3 Bison, Robert BC Ministry of Forests, Lands and Natural Resource Operations Presentation Title: British Columbia Steelhead Stock Status Review 2018 The vast majority of the estimated 423 steelhead populations in British Columbia belong to 3 major phylogenetic groups (MPG s); groups defined according to ancestral lineages and post glacial recolonization origins. In addition to these 3 major phylogenetic groups are 2 transition groups that reflect post glacial genetic mixing between the 3 MPG s. Steelhead population status within the North Coast MPG, which spans an area over the northern half of the steelhead range contained within the province, is informed mainly by the status of Skeena steelhead which appears to be stable over a 50 year monitoring time frame fluctuating near or above Smsy. All of the major population aggregates within the North Coast MPG lack data regarding fishery losses due to salmon fisheries which limits an understanding of status. The status of steelhead aggregates in the watersheds that are transboundary between BC and southeast Alaska are among the least understood within the North Coast MPG and BC in general. Steelhead population status within the Northern Transition group, located over a relatively small area along the mid latitudes of the BC coast, is informed mainly by Dean and Bella Coola steelhead. There is evidence that Dean steelhead may have undergone a decline to at least about the mid s while Bella Coola steelhead have clearly declined and remain in a state of relatively low abundance. As with the North Coast MPG stocks, data regarding fishery losses in salmon fisheries are lacking which limits an understanding of status. Steelhead population status in southern BC, which contains the South Coast MPG, and South Interior MPG and the Southern Transition group, is in a state of decline. In the South Interior MPG, the group is assessed by COSEWIC as containing two Designatable Units (DU s) named Thompson and Chilcotin. Both are currently classified by COSEWIC as Endangered and at imminent risk of extinction. The South Interior MPG shows a large and persistent decline in recruitment capacity, part of which is the result of a decline in per capita fecundity, but not exclusively. In the South Coast MPG, there is also evidence of wide spatial scale decline in recruitment capacity, most dramatically among winter run populations. Most recently, a decline in Gold River steelhead is particularly noteworthy given its history as a premier BC steelhead stream. The two major hatchery streams with the South Coast MPG are also exhibiting abundance declines within the last 6-8 years. Despite a few number of hatchery augmented streams in southern BC relative to the number streams that are not stocked, hatchery smolts appear to dominate the input of smolts into the Strait of Georgia and pinniped predation appears to account for a loss of the majority of the total smolt input. Within the South Coast MPG, pinniped predation, extreme climate events and climate trends, along with forestry related stream degradation are among the main conservation and management concerns. In the South Interior MPG and the Southern Transition, pinniped predation, offshore competition, and bycatch in salmon fisheries are among the main conservation and management concerns. Drought, forestry and agriculture related stream degradation, and hydroelectric operations are additional

5 Bumgarner, Joe Washington Department of Fish and Wildlife Presentation Title: Tucannon River Steelhead Management and Challenges from Overshoot at Columbia and Snake River Dams Joe Bumgarner and Todd Miller - WDFW In the Tucannon River, WDFW released a non-local stock of hatchery steelhead since the early 1980 s for harvest mitigation. Following ESA listing of steelhead in 1997, WDFW began testing a new localized stock utilizing natural origin returns. After a decade of testing, the local stock was adopted, and the non-local stock was eliminated from any further releases. The current program consists of both a conservation and harvest mitigation program. Two key questions have remained the same since the early 1980s: 1) What is the status/trend of natural steelhead returns? 2) Can hatchery program be operated with limited impacts to the natural population? Historical monitoring efforts to answer these questions included spawning ground surveys, adult trapping, and creel surveys. Spawning surveys were attempted for many years, but spring-time river conditions hampered surveys frequently, and lack of carcasses made it impossible to reliably estimate natural origin returns. Attempts to operate adult traps in the river to assess the natural returns or the new hatchery stock performance also proved unsuccessful. With the expanded use of PIT tags to monitor adult returns for both hatchery and natural steelhead from the Tucannon, and the installation of four in-stream PIT tag arrays, we now have a better understanding of steelhead migration, run timing, escapement, and spawning distributions. Initial overshoot rates for either hatchery natural or origin steelhead from the Tucannon River typically average about 60%, with 20% fallback, and nearly half remain above Lower Granite Dam and are dispersing to a variety of tributaries upstream. In the Tucannon River, on average about half of the natural origin fish are from other locations, and there are large numbers of hatchery steelhead from other programs during spawning. Natural fish have roughly the same distribution in the river, whereas hatchery releases tend to disperse relative to their release location. Strays from other programs tend to stay in the lower part of the river. With elimination of the LFH stock releases in the Tucannon, and a few years of no marked hatchery releases, we ve observed a near collapse of the fishery. Much of this is due to the shift in run timing, as most natural, Tucannon stock, and stray steelhead generally don t enter the river until after January. In answers to our management questions, natural returns are depressed in overall numbers, ~50% of Tucannon steelhead that cross Ice Harbor Dam never make back, and there are large number of hatchery strays present during the spawning season. Challenges to the hatchery program revolve around future harvest and could include the need for an adult trap in the lower Tucannon River for more aggressive management. Without an increase in harvest in the future, the hatchery program will likely be modified.

6 Camacho, Carlos Idaho Department of Fish and Game Presentation Title: Using genetics and scales to estimate Snake Basin steelhead emigration for VSP metrics at Lower Granite Dam Anadromous fish management programs in the Snake River basin include recovery planning and implementation efforts aimed at recovering ESA-listed wild steelhead stocks. However, specific data on Snake River steelhead populations are lacking, particularly for key smolt emigration parameters related to assessing the viability of salmonid populations. Starting in 2010, Idaho Fish and Game, in cooperation with Fish Passage Center s Smolt Monitoring Program, implemented a program to sample genetics and scales for ageing from wild smolts at Lower Granite Dam. The ultimate goal of this program was to develop productivity relationships at the genetic reporting group and MPG levels using stock-specific information relative to sex and age. For 2010 through 2017, smolt passage data and biological data collected from individuals trapped were used to decompose the annual smolt emigration into genetic stock, MPG, sex, and freshwater age abundance estimates. Furthermore, ad-intact hatchery fish were removed from the putatively wild fish collection using parental based tagging genetic techniques to refine estimates of truly wild fish. Wild smolt abundance and composition estimates were used to evaluate the status of wild populations relative to three viable salmonid population criteria: abundance, productivity, and diversity at the aggregate and genetic stock levels. We directly estimated juvenile abundance as well as elements of diversity such as sex ratio and age. For productivity analyses, age data was used to estimate abundance by brood year. In combination with similar adult abundance and composition at LGR, the smolt data will enable us to estimate adult-to-juvenile, juvenileto-adult, and adult-to-adult productivity at Lower Granite Dam. In addition, estimates by cohort could be used to forecast run sizes in subsequent years, and these forecasts are the basis for preliminary fisheries management plans in the Columbia River basin.

7 Cleary, Peter Nez Perce Tribe Presentation Title: Dispersion of Radio Tagged Steelhead Spawners in the South Fork Clearwater River South Fork Clearwater River steelhead adults were radio tagged in the fall and spring prior to spawning in the spring of 2013 to 2017 to evaluate and compare the spawning distribution of natural and two types of hatchery steelhead; a conventional program and a supplemental program. Returning hatchery and natural steelhead adults selected for radio tagging were either caught in the South Fork Clearwater River by sports anglers during the spring or at the Lower Granite Dam Adult Trap during the previous fall. Adults captured by sports anglers in the spring were identified by a combination of marks and tags. Adults captured at the Lower Granite Dam trap were identified by their juvenile PIT tag. Natural and hatchery steelhead spawn locations ranged from river kilometer 3 and 2, respectively, to river kilometer 100 for both groups with few fish spawning upstream of river kilometer 71 and showed no discernable differences between areas selected for spawning within the South Fork Clearwater River. Densities of hatchery spawners were visibly highest around juvenile release locations. Telemetry data of adult fish movement around river kilometer 71 suggests an adult migration passage barrier forms when discharge reaches approximately 1,000 cfs. The presence of a migration barrier with only one hatchery juvenile release site upstream of the migration barrier may explain why few adult steelhead spawners are utilizing the furthest upstream reaches of suitable steelhead spawning and rearing habitat in the South Fork Clearwater River.

8 Copeland, Tim Idaho Department of Fish and Game Presentation Title: Patterns of Iteroparity in Snake River Steelhead Trout Timothy Copeland, Carlos Camacho, Brett J. Bowersox, Michael W. Ackerman, Kristin K. Wright Steelhead trout have the most diverse life history repertoire of the Pacific salmonids. Unlike most of the other anadromous members of the genus, steelhead are capable of iteroparity (repeat spawning), but Snake River populations have perhaps the lowest iteroparity rates known for steelhead. In the Columbia Basin, steelhead managers are increasingly interested in increasing incidence of iteroparity as a conservation measure. However, there is little population-specific information about repeat-spawning steelhead to serve as a baseline to guide and evaluate management. In this study, we take advantage of three unique data sets to elucidate important patterns and characteristics of repeat-spawning steelhead in the Snake River basin in the last seven years. Repeat spawners were overwhelmingly female and were found in all stocks. There were slight majorities of iteroparous fish that first spawned after a year in the ocean and that skipped a year between spawns. Small females were most likely to survive to repeat spawn. Growth between spawns declined for larger, older steelhead. Percentage of repeat spawners ranged from 0.7% to 2.6% for steelhead spawning in Estimated abundance of repeat spawners doubled between 2010 and 2013 but then declined, lagging behind peaks in first-time spawner abundance. Therefore, conditions that promote survival to first spawning should eventually lead to more repeat spawners. Survival from first spawn to post-spawn emigration increased during the study but survival in the Columbia River estuary and Pacific Ocean declined such that overall survival to second spawn varied little. We hypothesize that iteroparity in Snake River steelhead is constrained by the rigor of the spawning migration (distance, elevation, timing) combined with a lack of timely post-spawn re-fueling. Hence, survival to second spawn is low for Snake River steelhead and most kelts need a full year to recondition. These factors are important to account for in any management regime to increase the incidence of iteroparity.

9 Craig, Bethany Washington Department of Fish and Wildlife Presentation Title: Monitoring Puget Sound Early Winter Steelhead Hatchery Releases Bethany Craig 1 * and Joseph Anderson 2 - (*) Presenter 1 Washington Department of Fish and Wildlife, Mill Creek Blvd., Mill Creek, WA, 98012, bethany.craig@dfw.wa.gov 2 Washington Department of Fish and Wildlife, 600 Capitol Way S, Olympia, WA, Oral presentation in Freshwater Ecology session at Pacific Coast Steelhead Management Meeting, Walla Walla, WA, March 20-22, 2018 WDFW s Puget Sound early winter steelhead hatchery programs support important tribal and recreational fisheries, and provide important cultural and economic benefits to western Washington. WDFW raises segregated, early winter steelhead in five watersheds in Puget Sound: the Nooksack, Stillaguamish, Snoqualmie, Skykomish, and Dungeness basins. While the early winter programs are designed to minimize risks to other populations, including ESA-listed wild Puget Sound steelhead and Chinook, monitoring is essential to ensure risks meet established conservation limits. WDFW and tribal co-managers recently initiated a comprehensive monitoring program to evaluate the genetic and ecological effects of the early winter programs on wild steelhead and Chinook. This talk will focus on efforts to quantify risks at the smolt life stage as fish are released from the hatcheries. Hatchery managers encourage rapid outmigration following release through releasing timing and volitional release strategy. To evaluate precocious maturation and the potential for residualism, we measured size, smolt index, sex, and maturity rates of early winter steelhead smolts at three facilities pre-release, and at two facilities after release in At pre-release the majority of sampled fish were smolting or transitioning to smolting, the sex ratio was approximately 50:50, and nearly all males were immature; however low levels of precocious maturation was detected at all facilities. The majority of non-migrant fish sampled after the end of the volitional release were male and 21% to 43% of males were mature or had initiated the maturation process. To evaluate the potential for ecological effects during outmigration, such as predation or competition, we monitored how quickly early winter steelhead smolts migrated after release via smolt trap catches. The first early winter steelhead were captured at downstream smolt traps within two to six days of the first release. Releases ranged from eleven days on the Dungeness to thirty-one days on the Stillaguamish, and the final early winter steelhead were detected eight to twenty-three days after the final release.

10 Cram, Jeremy Washington Department of Fish and Wildlife Presentation Title: Spatially Continuous Abundance and Age-Structure of Juvenile Steelhead Authors: Jeremy Cram and Dan Rawding Estimating juvenile abundance using spatially continuous mark-recapture methods for stream fishes may provide a viable alternative to site-based approaches that are less robust to patchy fish and habitat distributions. This presentation will focus on preliminary results from two years of investigation in Peshastin Creek, a key wild steelhead production area for the Wenatchee River. Results include fall parr abundance, distribution, and age-structure, estimates of spawner-to-parr survival, emigration patterns, and other life history information.

11 Daly, Elizabeth Oregon State University Presentation Title: The Changing North Pacific Ecosystem and Potential Impacts on Steelhead Elizabeth A. Daly *, Hillary L. Thalmann, and Richard D. Brodeur *Oregon State University, CIMRS, Hatfield Marine Science Center, Newport, OR Juvenile steelhead (Oncorhynchus mykiss) enter the northern California Current from the Columbia River and Northwest coastal rivers and include several populations listed under the US Endangered Species Act. However, relatively little is known about the response of these steelhead populations to interannual variability in ocean conditions. In , anomalously warm ocean conditions (including the warm blob ) persisted in the northern California Current and substantially affected the marine ecosystem. Returns of steelhead that out-migrated during the warm blob in 2015 were the lowest adult returns to the Columbia River in the last 20 years. Forecasts for cooler coastal waters in spring of 2018 are expected to be better for out-migrating salmon. However, winter PDO conditions are still positive, indicating above-average temperatures even during La Niña (cooler) conditions at the equator and the unusual ecosystem responses to the recent ocean conditions continue to be observed, even into To determine how steelhead respond to annual shifts in temperature, we compared juvenile steelhead diet composition, stomach fullness, size, and body condition across an 11 year timeseries ( , 2004, , ). This time-series included both the recent blob-influenced years as well as other warm, cold, and average temperature years. Steelhead from 2015 and 2016 exhibited some of the poorest body conditions and largest sizes in the time-series. In contrast, steelhead from 2010, a warm El Niñoinfluenced warm year, exhibited unusually high body condition and stomach fullness, but were quite small compared to the long-term mean. Steelhead diet composition varied between warm and cold years and between warm and average years, with steelhead consuming more insects, juvenile rockfish, and rare and unidentified fish in warm years. Unusual taxa were consumed in both 2015 (salps) and 2016 (juvenile smelts). These findings highlight the potential for warm ocean years to influence the diet composition and morphology of declining Columbia River steelhead populations, and may lead to a better understanding of what affects survival of juvenile steelhead in their early marine residence.

12 Faber, Derrek Oregon Department of Fish and Wildlife Presentation Title: Origin and Assignment of Hatchery and Wild Steelhead Spawning in Bakeoven and Buck Hollow Creeks, Deschutes River We identified the origin of steelhead (Oncorhynchus. mykiss) and fluvial redband trout (O. mykiss gairdneri) spawning in Buck Hollow and Bakeoven Creeks, eastside tributaries of the Deschutes River, from 2011 to Hatchery-origin steelhead were identified through the use of Parentage Based Tagging (PBT) used to identify broodstock at hatcheries in the Snake River basin. We used PBT results from these hatcheries to identify parent-pairs of adult offspring spawning in Bakeoven and Buck Hollow Creeks. Fin clips and external marks identified steelhead from the local Round Butte Hatchery, and coded wire tags and PIT tags identified steelhead from locations throughout the Columbia River Basin. Natural-origin steelhead and fluvial redband trout were identified using PBT as the juvenile or adult offspring of the parent-pairs collected in Bakeoven and Buck Hollow Creeks. Using these assignment methods, we were able to determine the hatchery origin, and release locations for hatchery-stray steelhead spawning in these tributaries. In addition, natural-origin assignments could be assessed and compared to the expected assignment rates given our known (and relatively high) trapping efficiencies. These assignment rates were much lower than expected, suggesting a prevalent source (or sources) of O. mykiss parents that were not sampled. The spawn-run timing of hatchery-origin steelhead was also evaluated and compared to natural-origin steelhead and fluvial redband trout, providing insight into the potential success of hatchery spawners. The assignment and source of hatchery and naturalorigin parents of fish returning to these tributaries offers understanding into the complex and diverse parent sources of Deschutes River Steelhead.

13 Falcy, Matt Oregon Department of Fish and Wildlife Presentation Title: Effects of Sea Lion Predation on Willamette River Winter Steelhead Viability Matt Falcy 1 and Bryan Wright 2 1 Oregon Department of Fish and Wildlife, Corvallis Research Lab, Hwy 34, Corvallis, OR ( matt.falcy@oregonstate.edu; Tel: ) 2 Oregon Department of Fish and Wildlife, Marine Mammal Program, 7118 NE Vandenberg Av, Corvallis, OR , USA California sea lions (CSL) began to regularly appear at Willamette Falls in the mid 1990s. A rigorous monitoring program began in 2014, revealing that CSL have consumed an average of at least 5300 salmonids per year in the immediate vicinity of Willamette Falls. At the same time, winter steelhead, which are listed as "threatened" under the federal Endangered Species Act, have declined in abundance. We conducted a population viability analysis of Willamette River winter steelhead to quantify extinction risk under current CSL predation rates, and the effect of removing CSL on steelhead extinction risk. The North Santiam population of winter steelhead has a 0.64 probability of extinction over 100 years if the 2017 predation rate by CSL is perpetuated, but probability of extinction drops to if CSL are absent. Other steelhead populations in the Willamette River showed qualitatively similar responses to CSL. Though many assumptions were needed to perform this work, the results suggest that CSL can extirpate winter steelhead populations, which has already occurred at "Ballard Locks" Washington. Removing CSL from Willamette Falls would greatly improve extinction risk.

MOVEMENT PATTERNS OF ADULT STEELHEAD AND ANGLERS IN THE MAINSTEM CLEARWATER RIVER, IDAHO Steelhead Oncorhynchus mykiss is a species of high economic value and supports popular sport fisheries across the Pacific Northwest. The purpose of this study was to describe movement and distribution patterns of wild and hatchery steelhead in the Clearwater River, Idaho. We were also focused on describing spatial movement patterns of anglers in the system. One-hundred-and-seventy-eight wild (n = 38) and hatchery (n = 140) steelhead were radio tagged at Lower Granite Dam in the fall of 2016 and spring of Steelhead tracking efforts have focused on the main-stem Clearwater River and Middle Fork Clearwater River. Tracking was conducted using twelve fixed stations and mobile tracking (automobile and drift boat). Steelhead movement data have provided insight on steelhead timing into the Clearwater River and timing into natal tributaries. Additionally, creel data was collected to provide information on the number of steelhead anglers and their locations. Results from this study will identify seasonal movement patterns of steelhead and distribution of anglers that will help manage the fishery.

15 Goodson, Kevin Oregon Department of Fish and Wildlife Presentation Title: Oregon s Steelhead Stock Status Kevin Goodson Oregon Department of Fish and Wildlife 4034 Fairview Industrial Drive, SE Salem, OR (503) Kevin.W.Goodson@State.OR.US Oregon steelhead have been classified by NOAA Fisheries into seven distinct population segments (DPS). Four of the DPS s are listed as threatened under the Endangered Species Act (ESA), and one is considered a species of concern. Steelhead in Oregon have seen a decline in abundance over the last two years. The statewide nature of the decline and regional drought suggests that poor juvenile and marine survival are likely causes. Data from dam counts and spawning surveys will be presented. Issues related to steelhead that Oregon is facing include pinniped predation, tributary overshoot, introgression/interactions with hatchery fish, and loss of habitat. These issues will be explored in separate presentations during the meeting. Oregon recently implemented new wild steelhead harvest fisheries in three coastal basins. Monitoring data from one of those fisheries will be shared.

16 Haeseker, Steven US Fish & Wildlife Service Presentation Title: Factors Associated With the Regional Patterns of Steelhead Survival in the Columbia River Basin Steelhead populations within the Columbia River basin enter the hydropower system at different locations with different levels of exposure to operational and environmental conditions during their juvenile outmigration. However, these populations share a common estuarine and oceanic environment following passage through the hydropower system. These common versus differential experiences allow for useful comparisons of population- and life-stage-specific survival rates and the factors that may be associated with those rates. In this presentation, we present mark-recapture estimates of in-river survival, ocean survival, and smolt-to-adult return rates for wild steelhead populations from the Yakima, John Day, and Snake rivers and examine how these survival rates vary over time and with environmental factors. Through simulation studies that incorporate these patterns of variability, we will explore survival targets and hydropower operations that may be necessary to support population recovery.

17 Johnson, Marc Oregon Department of Fish and Wildlife Presentation Title: Genetic influence from out-of-basin hatchery stocks on Upper Willamette River steelhead Marc A. Johnson, Thomas A. Friesen, David J. Teel, Donald M. Van Doornik, Maureen A. Hess, & James M. Myers Both resident and anadromous Oncorhynchus mykiss, respectively known as rainbow trout and steelhead, are native to Oregon s Upper Willamette River (UWR). Native UWR steelhead return from the ocean as adults during the late winter and early spring to spawn in the eastern tributaries of the basin that drain the Cascade Mountains. UWR steelhead are listed as threatened under the U.S. Endangered Species Act, and their recovery may be limited by effects from high-head dams, intense predation from pinnepeds, as well as ecological and genetic risks from hatchery-produced summer steelhead. In this study, we used baseline genotypic data from native UWR and nonnative hatchery-stocked steelhead to investigate genetic influence from the latter, as observed among unmarked juvenile samples collected at Willamette Falls ( ) and throughout the UWR basin (2014). Our results suggest a relatively low, but constant signal of natural production and hybridization from hatchery-stocked summer steelhead, originating from UWR tributaries with ongoing or past stocking histories. We discuss our ability to infer whether the patterns we observed can best be explained through ongoing introgression from hatchery steelhead, or whether past hatchery practices have left a genetic legacy in the UWR basin.

18 Johnson, Marc Oregon Department of Fish and Wildlife Presentation Title: Juvenile Physiology, Performance and Migration Behavior of Triploid Summer Steelhead Marc A. Johnson, Thomas A. Friesen, Andrew H. Dittman, Paul M. Olmsted, David L. G. Noakes, Ryan B. Couture, Carl B. Schreck, Thomas P. Quinn Ploidy manipulation can be used to sterilize and thereby genetically contain cultured fish that might otherwise interbreed with wild stocks. For salmonids, pressure-induced triploidy is sometimes used to sterilize resident trout species, but few studies have evaluated effects of triploidy on performance of free-ranging anadromous salmon and steelhead. Limited data from past studies suggest low return rates of sterilized adult salmon and steelhead, though mechanisms are unclear. Sterility may affect return rates through 1) failure to outmigrate as juveniles, 2) high mortality during or shortly after migration to saltwater, 3) failure to properly imprint upon and home to natal streams, 4) failure to manifest or respond to physiological cues that trigger adult spawning migration, or a combination of these. To identify and better understand the relative effects of factors influencing triploid performance, we produced two cohorts of triploid summer steelhead at the South Santiam Hatchery, Oregon, and compared metrics of growth, survivorship, plasma thyroxine, gill ATPase, outmigration timing and success, and adult return rates to those of full-sibling diploid controls. Overall, our results revealed slower growth, poor juvenile survival during transition to saltwater and significantly lower adult return rates by triploid steelhead, relative to diploid controls. These factors represent real challenges toward the application of induced triploidy as a management tool for free-ranging salmon and steelhead, though focused research may illuminate paths toward successful implementation.

19 Kendall, Neala W. Washington Department of Fish and Wildlife Presentation Title: Declining Pacific Northwest Steelhead Trout Adult Survival in the Ocean and Associated Ecosystem Indicators Kathryn L. Sobocinski (Long Live the Kings, NOAA Fisheries, Seattle, WA), Neala W. Kendall (WDFW, Olympia, WA), Correigh M. Greene (NOAA Fisheries, Seattle, WA) Marine survival of Puget Sound steelhead, documented from , declined since its peak in the early 1980s and has been consistently low since the early 1990s. We conducted a retrospective analysis aimed at evaluating how changing conditions in Puget Sound and the Pacific Ocean have related these steelhead marine survival rates, which are represented by time series data for 12 (2 wild and 10 hatchery) populations. We first developed hypotheses about steelhead marine survival based upon our mechanistic understanding of steelhead passage from their spawning streams to the Pacific Ocean and back. These hypotheses are related to steelhead predation, forage fish in Puget Sound, primary production in Puget Sound, estuary and early ocean conditions (specifically related to river flow and oceanography), and hatchery salmonid releases into Puget Sound. We then developed a suite of potential indicators that reflect changes to the environment of steelhead and are themselves changing over time and that are available or could be derived for the period of time of interest. These indicators include Puget Sound harbor seal abundance, resident orca abundance, herring spawning stock biomass, sea surface temperature, salinity, river flow rates and dates, and pink salmon abundance; Pacific Ocean SST, salinity, NPGO, PDO, MEI, PNI, NPI, upwelling index, and date of spring transition; Salish Sea human population abundance; and abundance and release dates of Puget Sound hatchery salmonids. To relate steelhead marine survival rates to the indicators we used generalized additive models (GAMs). Using model selection (based on AICc), we evaluated indicators individually and in combination, thereby addressing possible interactions and cumulative effects. The best-fitting model showed that seal abundance was strongly negatively related to steelhead survival rates, while SST and NPI values also had negative effects. PDO and the CV of hatchery subyearling Chinook release date had more moderate relationships with survival, with variable influence. Finally, there was a positive correlation between abundance of outmigrating hatchery fish and steelhead marine survival. We will continue to refine the models and assess the strength of the covariates in driving the model output.

20 Kendall, Neala W. Washington Department of Fish and Wildlife Presentation Title: Life-cycle Models for Yakima River O. mykiss: A Tool for Evaluating Environmental Factors on Fish Life History Strategy and Abundance Neala W. Kendall (WDFW, Olympia, WA), Chris Frederiksen (Yakama Nation, Yakima, WA) Neala.kendall@dfw.wa.gov, Chris_Frederiksen@Yakama.com Understanding how environmental factors will impact a fish s life history and abundance and therefore evaluating and prioritizing habitat restoration actions to promote conservation and recovery of Yakima River Basin steelhead/rainbow trout (Oncorhynchus mykiss) is a challenging but necessary management action. Given the complexity of these species habitats and life histories, there is also great interest in understanding the magnitude of climate change effects on salmonid habitat suitability and population persistence. Development and integration of existing O. mykiss life-cycle models can be used to identify limiting environmental factors and evaluate climate change effects that cause mortality at various life stages, acting as population bottlenecks. This work draws upon multiple existing life-cycle models to create updated, more biologically-accurate, population-specific models relevant to the Yakima River Basin. The updated life-cycle model predicts population abundance at each life stage and overall abundance and viability after a set number of years in accordance with various scenarios that captures anticipated changes to freshwater environmental variables (temperature and flow) and estuarine and ocean conditions. The outputs associated with the various scenarios can act as a decision support tool to guide restoration priorities so scientists and managers can focus on scenarios associated with higher population abundance and viability.

21 Klungle, Matthew M Washington Department of Fish and Wildlife Presentation Title: Assessing Environmental Factor That May Influence Life History Fiversity and Growth of Puget Sound Steelhead Smolts. Matthew Klungle, Washington Department of Fish and Wildlife, , matthew.klungle@dfw.wa.gov Clayton Kinsel, Washington Department of Fish and Wildlife, , clayton.kinsel@dfw.wa.gov Steelhead smolts typically have a more diverse life history in their freshwater phase than other Pacific salmonids and this diversity is expressed regionally among populations within the species. For example, the Nisqually River in South Puget Sound produces steelhead smolts that are larger on average than other Puget Sound smolts. Furthermore, steelhead smolts outmigrating from the Green River in Central Puget Sound and Nisqually River tend to be younger than conspecifics in North Puget Sound, suggesting that the Nisqually and Green rivers have higher growth rates. This presentation examines these growth rates and empirically assess what about the freshwater ecology of these systems produces smaller, larger, younger and older smolts. Specifically, we will compare growth among systems and assess whether environmental factors such as flow and temperature help explain some of the variability in four Puget Sound Rivers: the Dungeness, Skagit, Green and Nisqually.

22 LeMoine, Michael Upper Skagit Indian Tribe Presentation Title: Using demographic rates to estimate freshwater productivity of anadromous Oncorhynchus mykiss (steelhead) in the Skagit River, Washington. Author: Michael LeMoine, Upper Skagit Indian Tribe, Sedro Woolley, WA Anadromy in Oncorhynchus mykiss has been linked to individual decisions that are conditional to survival and growth during freshwater rearing. Both survival and growth can be influenced by environmental factors (e.g. temperature, flow, prey availability), and inter and intraspecific competition relative to genetic thresholds. Estimating changes in freshwater survival and growth can be important to tease out different factors selecting for anadromy and residency in O. mykiss, yet estimating O. mykiss survival through traditional Cormack-Jolley- Seber models can be complicated by the continuous emigration. I parameterized a Barker model, which estimates movement directly to estimate survival and emigration rates from two Skagit River tributaries. I used captures from summertime electrofishing surveys and subsequent resights and recovery from a stationary PIT antenna and season mobile PIT telemetry surveys. Freshwater productivity estimates from the Barker model were significantly lower and more precise than those attained by count estimates (adult to smolt ratios from spawn ground surveys and smolt trapping). Survival and emigration rates differed by stream and reach where survival was lower in reaches with warmer temperatures and emigration rates were higher in reaches with warmer temperatures and lower gradients. Even though this approach is not new, it is underutilized in steelhead monitoring. Over time, these demographic estimates may provide insight on reach and tributary scale influences on O. mykiss populations and can feed into demographic models for recovery planning.

23 Marston, Brian Alaska Department of Fish and Game Presentation Title: Status of Steelhead in Alaska Brian Marston Northern Kenai Peninsula Area Fishery Biologist Alaska Department of Fish and Game, Division of Sport Fish, Soldotna Alaska Steelhead Oncorhynchus mykiss are found in streams and rivers of coastal Alaska from Cape Muzon in Southeast (SE) Alaska to the Aleutian Peninsula of Southcentral (SC) Alaska at Port Moeller. Most of the known runs are small, containing fewer than 200 adults while the largest population in the Situk River of Southeast Alaska, averages 7-9,000 adult kelts. Kodiak Island and the Kenai Peninsula streams in southcentral Alaska also have runs from 200 to several thousand fish. Steelhead spawning in Alaska has been documented at elevations from 2 m in SE Alaska to 1,300 m in the Copper River drainage of SC Alaska. A total of ~ 4,500 km of stream are known to contain steelhead although much area remains to be surveyed. Sport fisheries occur in ~ 20 drainages. Yearly assessments of steelhead adult abundance are limited to 10 selected streams surveyed with snorkel counts, and 6 other streams assessed with weirs. These yearly assessments are done on streams in all of the largest sport fishery areas and are distributed throughout the known range of steelhead in Alaska. For 2016 and 2017 most streams in SE Alaska were at or slightly below average, while SC streams had very high counts or average counts. Length attributes as measured at the Situk River, where the largest fishery occurs, decreased markedly to the smallest on record in 2016 and returned to average in Two new steelhead research projects have also occurred recently on Kodiak Island (mark recapture) and on the Situk River (scale growth analysis and marine climate). Since 1995 sport fisheries have been conservatively managed with bait restrictions, spawning closures, yearly harvest limits of 2 fish and minimum size limits, or as catch and release only. In 2017 the largest southcentral Alaskan fishery in the Kasilof River was further restricted to catch and release only due to angler preference. Sport fishery catch across the state rose to exceed 20,000 fish in 2015 from a low of 10,155 in 2013 but has not recently achieved the average on 23,000. Sport fishery harvest continues to be low, descending to 65 fish in Directed commercial fishing for steelhead in Alaska has not occurred since Incidental harvests in commercial salmon fisheries were reportedly < 300 soon after 1995 but have increased to 860 fish in 2016 with new mandatory reporting requirements for incidental catch that were enacted in Reported subsistence use of steelhead is rare and remained below 100 fish per year for both 2016 and Overall resource management policy and regulation in Alaska is focused on preemptive management designed to avoid anthropogenic impacts to steelhead habitats and maintain the current abundance, age, and size attributes of the most heavily used wild steelhead populations.

24 Miller, Michael University of California, Davis Presentation Title: The Genetic and Evolutionary Basis of Summer Run Timing in Coastal Steelhead Coastal steelhead populations display two primary phenotypes in the timing and characteristics of their spawning migration across the southern part of their range in North America. Summer steelhead enter freshwater from the ocean in a sexually immature state during the late spring or early summer, migrate high into watersheds to near their spawning grounds, and hold over the summer in a fasted state while they sexually develop before spawning in the winter. Winter steelhead sexually mature in the ocean before entering freshwater in winter and migrating directly to their spawning grounds to spawn immediately. Because summer steelhead rely on cold, clean water throughout hot summer months, they are particularly vulnerable to anthropogenic activities that reduce water quality. Consequently, summer steelhead populations have either disappeared or dramatically declined since the arrival of Europeans. Here we use genomic methods to investigate the genetic and evolutionary basis of summer-run timing in coastal steelhead. Strikingly, we find that this complex phenotype is associated with the same single locus across multiple populations. Patterns of variation at this locus suggest that the summer-run alleles arose from a single evolutionary event and were subsequently spread to distant populations through straying and positive selection. Our results suggest that complex adaptive variation can depend on rare mutational events at a single locus and that, if summer-run populations are lost, the summer-run allele they depend on will also be lost and may take many thousands to millions of years to re-evolve.

25 Nelson, Jonathan California Department of Fish and Wildlife Presentation Title: California Steelhead: Management, Monitoring and Recovery Efforts Jonathan Nelson California Department of Fish and Wildlife, Fisheries Branch 830 S Street, Sacramento, CA ( , jonathan.nelson@wildlife.ca.gov California has six Distinct Population Segments (DPS) of steelhead as determined by the National Marine Fisheries Service (NMFS). The Northern California (NC), Central California Coast (CCC), California Central Valley (CV), South-Central California Coast (SCCC) DPS are listed as threatened under the Federal Endangered Species Act (ESA). The Southern California Coast (SCC) DPS is listed as endangered under ESA and the Klamath Mountains Province (KMP) DPS is not listed. In 2016, NMFS completed 5-year reviews of the five listed DPS and recommended not to change their listing status. There has not been a formal NMFS review of the KMP DPS since 2001 and the listing status of the KMP DPS remains not warranted. Based on limited census data on wild stocks, it appears that California s steelhead populations range from stable to declining. However, monitoring efforts in California to assess steelhead population abundance and trends remain limited challenging our ability to evaluate stock status. The California Department of Fish and Wildlife (CDFW) is working to expand the implementation of monitoring plans developed to assess both California Coastal and Central Valley steelhead populations. The primary limiting factors for California steelhead remain low streamflow and barriers impeding access to former habitat. Other challenges to steelhead recovery include habitat degradation, urbanization, poor land use practices, water diversions, hatchery practices, and drought. Many populations are still recovering from a prolonged drought that not only reduced habitat quality, but also restricted passage of migrating smolts, adult spawners, and kelts for several years. Recent natural disasters, such as fires and mudslides, as well as, a dam failure have further impacted some steelhead populations. Implementation of recovery actions for steelhead populations in California is critical. Current federal recovery plans exist for the five listed DPS (NMFS 2012, NMFS 2013, NMFS 2014, and NMFS 2016) and CDFW is updating the Steelhead Restoration and Management Plan for California (1996). Restoration efforts for steelhead have focused on priority recovery task recommendations in these documents. CDFW is also continuing to implement hatchery reforms identified by the California Hatchery Review Report (2012) and work with partner agencies to develop hatchery genetic management plans for steelhead programs.

26 Pepping, Michelle University of California, Davis Presentation Title: Using Genetics to Investigate the Spawning and Rearing Distribution of Summer and Winter Steelhead in the North Umpqua Basin The North Umpqua River is famous for its unique run of summer steelhead. Summer steelhead are present in far fewer rivers and typically have much smaller population sizes than winter steelhead. This is consistent with the steelhead in the North Umpqua Basin, where the summer population averages approximately one sixth the size of the winter population and is of greater conservation concern. Despite the importance and conservation concerns of North Umpqua summer stealhead, little is known about the locations they use for spawning and rearing. We collected juvenile steelhead tissue samples from many sites throughout the North Umpqua Basin and use recently developed genetic markers in the GREB1L region to distinguish their run timing. We found strong partitioning of summer and winter individuals within the basin, where different tributaries were preferentially utilized by a single run. Understanding which locations are important for the spawning and rearing of summer steelhead provides useful information for management and conservation to secure the long term persistence of this unique population.

Biological Sciences, University of Idaho, Moscow, Idaho 2) Columbia River Inter-Tribal Fish Commission, Portland, Oregon 3) Yakama Nation Fisheries, Toppenish, Washington 4) Nez Perce Tribe Fisheries, Lapwai, Idaho Every spring, large numbers of post-spawning steelhead kelts migrate downstream throughout the Columbia River Basin (CRB), but few return as repeat spawners. Reconditioning of female kelts is being implemented as a recovery measure for ESA-listed CRB steelhead stocks. Downstream migrating kelts are captured, held in tanks and fed, and then released in the fall to migrate upstream and spawn again. Research on the physiology of kelt reconditioning has shown that fish divide into consecutive and skip spawners (1 and 2 year spawning interval). Fish can be screened for maturation status using plasma estradiol level by mid-august, enabling separate management of consecutive and skip spawners. Consecutive maturation rates range widely, with typical rates near 60%. Maturation decisions appear to be made early, as significant differences in growth are found within 10 weeks after spawning. Rematuring consecutive spawners are larger and have greater energy reserves compared with maiden spawners in the fall, and have similar or higher plasma estradiol and vitellogenin levels. Studies using a hatchery kelt model have shown that reconditioned consecutive spawners are more fecund and produce larger eggs than maidens, with an additional increase for skip spawners, and that spawn timing is not substantially altered by reconditioning. Steelhead kelt reconditioning has the potential to contribute to recovery by increasing the stability, diversity, and productivity of listed populations.

28 Ruzycki, James Oregon Department of Fish and Wildlife Presentation Title: Estimating Escapement of Summer Steelhead Using Redd Surveys: What have we learned and where do we go? In 2002, we initiated an effort to refine summer steelhead redd survey methods to increase accuracy and precision of natural-origin spawner abundance (NOSA) estimates across several populations in Eastern Oregon. While index redd surveys had been conducted since the 1950 s, they were inadequate for estimating spawner status. We incorporated a statistical GRTS and rotating panel survey design to estimate and spatially represent steelhead populations across watersheds. Repeat surveys were incorporated to compensate for temporal variation within, and across years. To convert redd counts to spawner estimates, we developed fish/redd ratios by surveying a representative watershed that also had a reliable weir for counting passed adults. To improve accuracy, we employed several methods to compensate for our inability to observe redds given variable flow conditions. To increase precision, we stratified watersheds by stream classification and gradient with modest success. Despite these efforts, estimating NOSA using redd survey methods remains a challenge, which has encouraged us to continue exploring alternative methods for estimating spawners in watersheds that lack counting structures and monitoring infrastructure.
