3 3 SURVEY AND MANAGEMENT SUMMARY The Lake Jacksonville fish community was surveyed from June 2008 through May 2009 using an electrofisher, gill nets, and trap nets. A vegetation survey was conducted in August A roving creel survey was conducted from December 2008 through May 2009 and collected angler use and harvest information. This report summarizes results of the surveys and contains a management plan based on those findings. Reservoir description: Lake Jacksonville is a 1,208-acre reservoir on Gum Creek (a tributary of the Neches River), Texas, built to provide water for municipal and industrial purposes. Boat and bank angler access is adequate. Handicap-specific facilities were present in the parking lot and restrooms near the main boat ramp. Water is clear and low in productivity. Land surrounding the reservoir is highly modified for residential development and approximately 40% of the shoreline has bulkhead at the land/water interface. Management history: Important sport fish include sunfishes, largemouth bass, channel catfish, white crappie and black crappie. Largemouth bass are managed with an 18-inch minimum-length limit; remaining species are managed under the statewide harvest regulations. Supplemental largemouth bass sampling was conducted in 2006 and stockings were conducted in 2006 and An integrated vegetation management plan was initiated in 1997 featuring triploid grass carp stocking, release of hydrilla flies, herbicide treatments, and native plant introduction. Vegetation surveys have been conducted twice a year (early spring and late summer). Herbicide treatments were continued annually but hydrilla continued to expand. In 2006 and 2007 a total of 3,890 triploid grass carp were stocked (10 fish/hydrilla acre). In July 2007 a major flood event removed most of the hydrilla and grass carp herbivory prevented reestablishment. By summer 2008 hydrilla was reduced to trace coverage and native vegetation was sparse. Fish community: Prey species: Threadfin shad were present in the reservoir but the prey base continued to be dominated by sunfish species. Electrofishing catch rate of both threadfin and gizzard shad increased over previous surveys; however, most gizzard shad were too large to serve as prey. Catch rates of sunfishes <6 inches was high. Overall prey availability was adequate. Catfishes: Channel catfish, although still present, were rare. Only one channel catfish was collected by standardized gill netting in spring White bass: White bass were still present in Lake Jacksonville but abundance is low. Black basses: Largemouth bass were the most sought-after species by anglers at Lake Jacksonville during the winter/spring creel survey and angler success was high. Relative abundance was similar to previous surveys but size structure has continued to improve since Spotted bass were present but contribute little to the fishery. Crappie: Crappie was the second most sought after sport fish during the winter/spring creel surveys; however, no crappie were collected in trap nets in Management strategies: Conduct additional electrofishing in fall 2010 to monitor largemouth bass and prey populations. Discuss the possibility of the City of Jacksonville purchasing advanced channel catfish fingerlings. Continue native vegetation restoration and discuss the possibility of removing protection for triploid grass carp. Solicit partners to construct and install bamboo fish attractors.
4 4 INTRODUCTION This document is a summary of fisheries data collected from Lake Jacksonville from June 2008 through May 2009.The purpose of this document is to provide fisheries information and make management recommendations to protect and improve the sport fishery. While information on other species was collected, this report deals primarily with major sport fishes and important prey species. Historical data are presented with the 2008 and 2009 data for comparison where appropriate. Reservoir Description Lake Jacksonville is a 1,208-acre reservoir on Gum Creek, Texas, a tributary of the Neches River. The reservoir was built to provide water for municipal and industrial purposes. Lake Jacksonville is slightly eutrophic with a mean mg/m 3 chlorophyll a = 4.58 (Texas Commission on Environmental Quality 2008). The littoral zone consists of a variety of physical habitat types (Table 4). The majority of the shoreline is a combination of bulkhead and boat docks (38%), eroded shoreline with boat docks (28%) or featureless (26%). Boat access is adequate, but bank access was limited to city park locations. Boats can be launched from three public ramps and a city owned marina provides fuel on the water. There are no handicap-specific facilities, but most are accessible. Other descriptive characteristics for Lake Jacksonville are found in Table 1. Management History Previous management strategies and actions: Management strategies and actions from the previous survey report (Ott and Bister 2005) included: 1. Continue electrofishing on a biennial basis to monitor and evaluate the largemouth bass (Micropterus salmoides) population. Conduct electrophoretic analysis of age-0 largemouth bass during fall 2008 to assess the success of stocking recommended for 2005 and Action: Florida largemouth bass (M. s. Floridanus) fingerlings were stocked in spring 2006 and Optional electrofishing was conducted in fall 2006 and genetic analysis of largemouth bass was conducted during routine electrofishing in fall Monitor changes in the aquatic plant community through annual surveys. Recommend construction of a replacement fish barrier to allow the possibility of additional triploid grass carp (Ctenopharyngodon idella) stocking, as was proposed under the integrated hydrilla (Hydrilla verticillata) management plan. Continue assisting the City of Jacksonville in obtaining USACOE matching funds (if available) to offset costs for herbicide treatments. Continue assisting the City in obtaining discounted herbicide and or experimental products to control hydrilla. Assist the City of Jacksonville in obtaining hydrilla flies (Hydrellia pakistanae) as an additional control measure for hydrilla and as part of the integrated management plan Action: Aquatic plant community was assessed through exotic vegetation surveys conducted in the spring and late summer each year. An improved fish barrier was designed and installed at the outflow and grass carp were stocked at an effective rate of 10/hydrilla acre. City was able to obtain USACOE matching funds in 2005 and 2006, and district staff coordinated herbicide donations to supplement matching funds. District staff and USACOE released 750,000 hydrilla flies in Consult with the City of Jacksonville about obtaining advance-sized channel catfish (Ictalurus punctatus) from a private vendor. Assist assisting the City of Jacksonville in seeking sponsorship to offset the cost of a stocking program. Evaluate the efficacy of any resulting stocking program during routine gill netting in spring Action: Funding for channel catfish stocking was diverted to hydrilla control. Gill netting was conducted in spring Include Lake Jacksonville in news releases that promote angling opportunities in the East Texas area. Give presentations about the lake and fisheries to interested groups and area residents as requested. Provide lake-specific regulation posters to angling-oriented businesses serving the Lake Jacksonville area. Maintain regulation signs previously mounted at public and private boat ramps on Lake Jacksonville. Action: News releases and interviews regarding the fishery and habitat management plan
5 5 have been provided to local media. Presentations have been conducted to the Jacksonville City Council, and with angler and home owner groups. Regulation posters and posters informing the public about the habitat management plan have been provided. Harvest regulation history: Sport fishes in Lake Jacksonville have been managed with statewide harvest regulations except for an 18-inch minimum-length limit for largemouth bass (Table 2) which was imposed in Regulations have not changed since the last survey (Ott and Bister 2005). Stocking history: Triploid grass carp and Florida largemouth bass are the only species stocked since the last survey report. Triploid grass carp were stocked as part of an integrated vegetation management plan. Florida largemouth bass were initially stocked in 1975 and have been stocked periodically since then to enhance the trophy potential of the fishery. A complete stocking history is found in Table 3. Vegetation/habitat history: Aquatic vegetation has historically been scarce on Lake Jacksonville. However, in fall 1995 approximately 20 acres of hydrilla was discovered and rapidly expanded. To control the hydrilla an integrated vegetation management plan was initiated in This plan featured low density triploid grass carp stocking, herbicide treatments, and native plant introduction. Following a flood in February 1999 the grass carp barrier was removed disallowing any additional grass carp stocking. Annual herbicide treatments were conducted but hydrilla continued to expand to over 300 acres with approximately 95 acres of native vegetation. In 2006 an improved fish barrier was constructed and in 2006 and 2007 a total of 3,890 triploid grass carp were stocked (10/hydrilla acre) and approximately 750,000 hydrilla flies were released. In July 2007 a major flood event removed most of the hydrilla and grass carp herbivory prevented reestablishment. By summer 2008 <1.0 acre of hydrilla and only approximately 30 acres of native vegetation were observed. METHODS Fishes were collected by electrofishing (1 hour at 12, 5-min stations), gill netting (5 net nights at 5 stations), and trap netting (5 net nights at 5 stations). Catch per unit effort (CPUE) for electrofishing was recorded as the number of fish caught per hour (fish/h) of actual electrofishing and, for gill and trap nets, as the number of fish per net night (fish/nn). A vegetation survey was conducted in August 2004 and was repeated at the beginning and end of the growing season 2005 through Roving creel surveys were conducted from December 2008 through May Surveys consisted of 9 creel days per quarter (4 weekdays and 5 weekend days); angler counts were instantaneous and were conducted at a random start time during the survey day. All survey dates were randomly selected and all surveys were conducted according to the Fishery Assessment Procedures (TPWD, Inland Fisheries Division, unpublished manual revised 2005). Sampling statistics (CPUE for various length categories), structural indices [Proportional Stock Density (PSD), Relative Stock Density (RSD)], and condition indices [relative weight (W r )] were calculated for target fishes according to Anderson and Neumann (1996). Index of vulnerability (IOV) was calculated for gizzard shad (Dorsoma cepedianum), (DiCenzo et al. 1996). Relative standard error (RSE = 100 X SE of the estimate/estimate) was calculated for all CPUE statistics and for creel statistics and SE was calculated for structural indices and IOV. For largemouth bass, ages were determined using otoliths from 13 specimens with lengths ranging from inches. Water level data were obtained from the United States Geological Survey web site (USGS 2008). RESULTS AND DISCUSSION Habitat: Physical habitat types were similar to those found in previous surveys. Littoral habitat consisted mainly of bulkhead and boat docks, eroded shoreline with boat docks, and featureless. Hydrilla has been reduced to less than one acre and is present only where it is protected by the grass carp barrier at the outflow. Alligator weed (Althernanthera philoxeroides) was the only other prohibited species identified and occupied approximately two acres. Native emergent vegetation occupied approximately 30 acres of the reservoir (2.5% coverage) and is most abundant in the far upper end and at the upper ends of the Byrd Branch and Cat Creek arms. Dominant native emergent and floating leaved species included: fragrant
6 6 water lily, (Nymphaea odorata), maidencane (Panicum hemitomon), common reed (Phragmites australis), giant cutgrass (Zizaniopsis miliacea), and yellow water lily (Nuphar luteum). Submersed native species included: coontail (Ceratophyllum demersum), pondweed (potamogeton spp.), and wild celery (Vallisneria Americana), (Table 4). Native plant exclosures have been reconstructed in Cat Creek and Byrd Branch and contain wild celery colonies. Creel: Directed fishing effort by anglers was highest (68%) for largemouth bass during the winter 2008 through spring 2009 creel survey (Table 5). Crappie represented the second highest directed effort (14%). However, few crappie anglers were encountered during the creel period and relative standard error (RSE) is high for this estimate. Total fishing effort for all species at Lake Jacksonville was 9,656 hours from December 2008 through May 2009 and anglers spent an estimated $36,990 on direct expenditures (Table 6). Adverse weather during spring 2009 likely reduced total effort and angler expenditures; three of the 9 creel days surveyed for the quarter resulted in zero effort. Prey species: Both threadfin shad (D. petenense) and gizzard shad were present in Lake Jacksonville (Appendix A). The gizzard shad electrofishing catch rate (13/h) increased slightly from the 2004 (4/h); none were collected in 2006 (Figure 2). Furthermore, Index of Vulnerability (IOV) for gizzard shad was 15 indicating that most were too large for predators to consume. Threadfin shad electrofishing catch rate (111/h) was somewhat higher than in recent surveys (8/h, 2004; 0/h, 2006) and is likely related to habitat changes. Nutrients previously tied up in macrophyte biomass (hydrilla) were then available for phytoplankton production. However, overall abundance of shad was still low and the prey base continued to be dominated by sunfish species. The sunfish community included redbreast sunfish (Lepomis auritus), bluegill (L. macrochirus) and redear sunfish (L. microlophus) and all species were abundant. Combined catch rate for all sunfish species was 518/h, (Appendix 1). Fish collected were mostly <6 inches (Figures 3, 4, and 5) and functioned primarily as prey. Although 11% of the angler effort was directed at sunfish species during the December 2008 through May 2009 creel survey, no harvest was documented. Catfish: Lake Jacksonville supports a low-density channel catfish population with poor natural recruitment. Poor recruitment is likely related to high water clarity (Secchi visibility >6 ft) and consequential predation by largemouth bass. Only one channel catfish was caught by gill net in 2009 (Figure 6) and that individual was large (23 inches) and mature. No evidence of recruitment was detected. This was similar to 2005 when no channel catfish were caught and 2001 when only 6 were caught. No directed angling effort for catfish was documented during the creel period. White bass: Similar to previous surveys in 2001 and 2005 white bass (Morone chrysops) catch rate in gill nets continued to be low (Figure 7). Low abundance of white bass in Lake Jacksonville is likely a result of poor spawning habitat in the relatively small streams that feed the reservoir. It may also be related to the relatively low density of shad present as the relative weight (W r ) of the single specimen collected was only 80. No directed angling effort for white bass was documented during the creel period. Black basses: Spotted bass were collected by electrofishing at a higher rate than past surveys (Figure 8) but all were small (an 11 inch specimen was the largest collected). It is unlikely that this species contributes appreciably to the fishery; no catch or harvest of spotted bass was documented during the creel period. Electrofishing catch rate of largemouth bass in 2008 (80/h) was similar to 2002 (79/h) and 2006 (78/h), (Figure 9). Catch rate of stock-size (>8 inches) largemouth bass was similar to 2006 but was nearly twice what was caught in Proportional stock density (PSD) has continued to improve from 37 (slightly below the target range) in 2004 to 73 (slightly above the target range) in Relative weight (W r ) was >90 for fish >8 inches in length and showed marked improvement from The improvement in W r is likely due to greater prey accessibility as a result of reduction in hydrilla. Average age for largemouth bass at 14 inches ( ) was 2.6 years (N =13, range 2-4 years) and was similar to growth in other lakes of similar size in the area. The prevalence of Florida bass alleles in the population was similar to previous surveys despite the stockings in 2006 and 2007 (Table 8); but the percentage of pure Florida largemouth bass declined. However, in 2008 microsatellite DNA analysis was used to determine
7 7 largemouth bass genetic composition and results may not be directly comparable to historical data. The largemouth bass fishery at Lake Jacksonville is the most popular of any species with 68% of the directed angling effort in the December 2008 through May 2009 creel survey. Angler success was unusually high with an angler catch rate of 1.8 fish per hour (Table 7). Anglers released 55% of legal fish caught; however, fish held in live wells by tournament anglers comprised 50% of the harvested fish observed (Figure 10) so it is likely that eventual release was higher. Crappie: No crappie were collected by trap net in fall 2008 and trap net catches (Appendix A) and catch rate in previous surveys were low (Ott & Bister, 2001; Ott & Bister, 2005) Fourteen percent (1,318 hours) of the estimated angler effort was directed toward crappie during the December 2008 through May 2009 creel survey and although reported angler success was high (7.9 fish/h), only one party interviewed targeting crappie actually caught any during the creel period and relative standard errors around catch and harvest estimates were high (Table 9).
8 8 Fisheries management plan for Lake Jacksonville, Texas Prepared July 2009 ISSUE 1: Lake Jacksonville has traditionally provided a high-quality largemouth bass fishery and it is important to local anglers. Changes in habitat have influenced angler perceptions of fishery status. MANAGEMENT STRATEGY 1. Continue electrofishing surveys every other year beginning in 2010 to monitor largemouth bass and prey populations. 2. Continue conducting outreach presentations to area angling groups as requested. 3. Continue providing information to local news media concerning the status of the fishery. ISSUE 2: The channel catfish population is of low density and continues to be hindered by recruitment problems. Periodic restocking with fish large enough to escape predation is necessary to produce a fishery. MANAGEMENT STRATEGIES 1. Now that hydrilla is under control and city funding may be more available, revisit the idea of accessory stocking with > 10-inch fingerlings. 2. Solicit partners with angling and/or home-owner groups to finance stocking. ISSUE 3: The Lake Jacksonville aquatic vegetation community consists primarily of emergent and floating-leaved species in the upper end of the reservoir. Nursery colonies of several native submersed species are still present in Byrd Branch and Cat Creek where exclosures protect them from grass carp herbivory. Several water-front property owners have shown interest in partnering with TPWD by allowing exclosures and plant introductions in front of their property. MANAGEMENT STRATEGIES 1. Continue annual vegetation survey to monitor recovery of native and or exotic plant species as grass carp mortality lessens herbivory. 2. Maintain existing exclosures to ensure continued production of native plant propagules. 3. Continue soliciting partners among property owners and angler groups in native plant restoration. 4. Consult with the City of Jacksonville about additional habitat enhancement as stated in the Lake Jacksonville Aquatic Vegetation Management Plan. 5. Implement additional native aquatic plant enhancements where and when possible. 6. Solicit partnership with angling groups to construct and install artificial reefs. ISSUE 4: Triploid grass carp stocked for hydrilla control have successfully reduced hydrilla below the level specified in the Lake Jacksonville Aquatic Vegetation Management Plan and are interfering with native vegetation recovery. MANAGEMENT STRATEGIES 1. Under the terms of the integrated management plan discuss with the City the possibility of removing protection of grass carp and allowing angler harvest. SAMPLING SCHEDULE JUSTIFICATION: The proposed sampling schedule includes an annual habitat survey, additional electrofishing in 2010, and mandatory monitoring in (Table 10).
