INTRODUCTION This Federal Aid Project provided funding to the Alaska Department of Fish and Game, Division of Commercial Fisheries, for collection of biological and fleet performance data at major ports of landing in Southeast Alaska and Yakutat during the 1987-1991 troll, gill net, and purse seine fisheries. This data is used by federal, state, and private agencies in a variety of management and research applications. All port sampling activities associated with coded microwire tag (CWT) recovery, troll fishery performance data (FPD), biological sampling for scale, age, sex, and size (AWL) data, and sex-ratio sampling were unified under this project. Federal Pacific Salmon Treaty research funding supported the sampling of sockeye salmon for AWL data in southern Southeast Alaskan catches and escapements. his project supported three components: (1) CWT sampling; (2) AWL sampling and; (3) FPD sampling. This report includes summaries of CWT, AWL, and FPD sampling effort. Tables of sampling effort for the final year of the contract, the 1990 season, are presented here. Tables of sampling effort for prior years of the contract are presented in the appropriate annual reports. CODED MICROWIRE TAG RECOVERY Methods and Procedures Project goals were to a minimum of 20 of both the chinook and coho salmon harvested in the troll and net fisheries; 20 of the chum salmon harvested in each of the Districts 101-11 net fisheries; and 20 of the sockeye salmon harvested in the each of the Districts 101 through 108 seine and gill net fisheries. The fall run of chum salmon in the District 102 purse seine fishery is not specifically d since it is a wild stock fishery and none of the stocks targeted are represented by coded wire tags. The same is true for the District 115 gill net fishery. Pacific Salmon Commission funds supported increased sampling effort on chinook salmon throughout the year. Alaska Department of Fish and Game employees representatively d chinook, coho, chum, and sockeye salmon for CWT data throughout the duration of the 1987-1990 troll, purse seine, and gill net fisheries. rs were stationed at the principal ports of Sitka, Port Alexander, Pelican, Juneau, Petersburg, Wrangell, Ketchikan, Craig, Excursion Inlet, Hoonah, and Yakutat. Data and heads of all marked fish d were sent to the Fisheries Research, Enhancement, and Development Division's (ADF&G) tag lab in Juneau on a weekly basis. The sampling effort was monitored throughout the season and adjustments were made in manpower and sampling assignments among the ports to assure that the sampling level was representative throughout the region. Results and Discussion Our CWT sampling goals were generally met or exceeded for all species in the troll and gill net fisheries. However, some undersampling of coho, chum, and sockeye salmon occurred in the purse seine fisheries. This undersampling
typically occurs around the peak of the pink salmon return when rs have to search through many pink salmon to find the species they wish to. Some undersampling also occurred in those purse seine and gill net fisheries in which few of the target species were caught. Project personnel d 118,06 (35.6) of a total catch of 33,06 chinook salmon in the 7/1/90-6/30/91 troll fisheries (Table 1). A total of 67,766 coho salmon were d from the troll fisheries, for a sampling rate of 20. (Table 2). In the 1990 regional purse seine fisheries, a total of 5,022 chinook (Table 3), 81,033 coho (Table ), 225,6 chum (Table 5), and 202,585 sockeye salmon (Table 6) were d, resulting in respective sampling rates of 3, 21, 21, and 21. In 1990 gill net fisheries, regional personnel d,373 chinook (Table 7), 108,758 coho (Table 8), 202,657 chum (Table 9), and 128,03 (Districts 101-108 only) sockeye salmon (Table 10). This effort corresponded to 28 of the chinook, 21 of the coho, 29 of the chum, and 39 of the sockeye (Dist. 101-108) salmon harvested. These totals include Annette Island Fishery Reserve gill net catches which were d in Metlakatla, under a separate program, by local residents. SCALE, AGE, SEX, AND SIZE SAMPLING Methods and Procedures The annual goal of the project is to develop a comprehensive data base on the abundance, age, sex, and size composition of sockeye, chum, coho, and chinook salmon in Southeast Alaska catches and escapements. This data base should enable us to test models which estimate stock contributions and interceptions, to determine migratory timing patterns, to develop spawner/recruit relationships, and to make preseason and in-season forecasts of returns. Scale, age, sex, and size data (AWL) were collected by ADF&G employees from catches at all ports listed above, and escapements of chinook, sockeye, chum, and coho salmon from throughout Southeast Alaska and Yakutat during the summer of 1990. Project personnel d chinook salmon from the winter troll fishery, chinook and coho salmon from the summer troll fishery, and chinook, coho, sockeye, and chum salmon from the purse seine and gill net fisheries. From the Yakutat area set net catches we d chinook, coho, sockeye, and chum salmon. Chinook, coho, sockeye, and chum salmon escapements were d by ADF&G and other agency personnel in many major and minor systems in the region. Sampling goals, by stratum, were designed to collect sufficient numbers to estimate the proportion of each age class to within 2 5 percentage points 90 of the time in each stratum based on the standard binomial formulae (Cochran 1977). For major net fisheries, the desired strata was for weekly catch by district and gear type. Troll fishery strata combined districts into quadrants. Those species with more age classes required greater sizes. Generally between 00 to 500 s per strata were sufficient to achieve the goals. Pink salmon sex-ratio sampling was conducted to accumulate the data base required to determine if run timing could be monitored based on the sex ratios found in
the weekly harvests. The goal was to a minimum of 300 pink salmon for sex each week from locations within the purse seine fisheries. Particular sampling locations were chosen because they: 1) were usually open to weekly fishing; and 2) we could usually obtain mixed s from these locations. Results and Discussion In general, all AWL sampling goals were achieved in 1990. The 1990 AWL collection by species, gear, and week are presented in Tables 11-20. Compilation of AWL data for sockeye salmon were currently under review and will be presented by Rowse (in prep). Compilation of data for other species is currently being prepared by Pahlke (in prep) for chinook salmon, Dangel (in prep) for chum salmon, and Wood (in prep) for coho salmon. AWL data for salmon d in Yakutat area fisheries will be presented in Rowse (in prep). A summary of the numbers of pink salmon sex-ratio d in 1989, as well as the s sex-ratio, is presented in Table 21. FISHERY PERFORMANCE DATA The project goal was to 2,000 randomly selected summer troll fishery deliveries for FPD. Alaska Department of Fish and Game employees d summer troll deliveries to the ports listed above for fishery performance data. The FPD sampling was conducted in conjunction with CWT sampling. Troll fishermen were interviewed at the time of landing to obtain catch and effort data. This FPD data was used primarily to estimate chinook salmon harvests to date and to project catch rates as sales receipts ("fish tickets") that provide this information are not available until several days after the fish are sold. These estimates were essential for in-season regulation of the fishery to insure that chinook salmon catch quotas set by the Alaska Board of Fisheries, the North Pacific Fishery Management Council, and the Pacific Salmon Commission were not exceeded. Approximately 1,922 complete FPD interviews were obtained from the 1990 summer troll fishery. Detailed FPD sampling rates are presented in Table 22.
