To achieve these effects, methods of Largemouth Bass recruitment control should avoid reducing the productivity of their primary prey species, Bluegill Lepomis macrochirus . We tested this hypothesis by evaluating the effects of shoreline rotenone application on Bluegill and age‐0 and age‐1 Largemouth Bass density, growth, and survival in 15 Alabama small impoundments. Following treatment, Largemouth Bass age‐0 densities declined and mean age‐1 length increased, whereas Bluegill populations were not significantly reduced. Our study indicates that shoreline rotenone application may be a valuable method for reducing Largemouth Bass recruitment and increasing Largemouth Bass age‐1 growth in small impoundments. However, further research is needed to understand the effects of treatment on non‐target fishes and better assess the effects of factors such as impoundment surface area and treatment frequency and duration on the ultimate utility of the approach.","PeriodicalId":19263,"journal":{"name":"North American Journal of Fisheries Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135132867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most pervasive are questions about whether LIS users catch fish more effectively than non‐users. This project was designed to elucidate effects of LIS use on catch of Blue Catfish Ictalurus furcatus from Milford Reservoir, Kansas. Additionally, we sought to identify angler perception of LIS and quantify differences in angling behavior between users and non‐users. Methods We organized a Blue Catfish angling experiment where 16 anglers used LIS and 16 anglers did not. The experiment was followed by dissemination of a survey to measure angler experience and skill, perception of LIS, and identify behavior patterns from groups that did and did not have access to the technology. A multivariate linear model was used to identify how LIS use, angling experience, and self‐assessed angling skill influenced fish catch. Comparisons of LIS perceptions and angling behavior were also evaluated between treatment groups. Result There was no difference in Blue Catfish mass captured per five‐hour angling trial by anglers using LIS (mean = 14.57 kg, SE = 3.38) and anglers not using LIS (mean = 16.97 kg, SE = 2.29). However, self‐rating of angling skill was identified as a predictor in a supported model but little variation in catch was explained ( R 2 = 0.169). Anglers using LIS thought their time spent searching and catch would have been similar if they did not use LIS. Anglers that did not use LIS thought they would spend more time searching for fish and catch may have increased if using LIS. Time spent searching for angling locations was greater for anglers using LIS than those not using LIS. Conclusion Results from this study suggest use of LIS may influence Blue Catfish angler perception and behavior more than catch.","PeriodicalId":19263,"journal":{"name":"North American Journal of Fisheries Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135246395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of our study was to determine the effect of Salmincola californiensis on the vulnerability of Rainbow Trout to recreational angling and short‐term survival after being caught and released. We compared the prevalence and intensity of infection of S. californiensis on Rainbow Trout caught while angling and with a backpack electrofisher in May and October 2020 in Birch Creek, Idaho. In October, we also conducted a stress test (i.e. air exposure treatment) on trout caught by angling to determine the effects of parasitic copepods on short‐term survival of Rainbow Trout in a catch‐and‐release fishery. Infection with S. californiensis did not influence the vulnerability of Rainbow Trout to angling. After adjusting for sample size and size distribution, prevalence of infection in May was 48.3% for Rainbow Trout caught while electrofishing compared to 49.3% for Rainbow Trout caught while angling. In October, prevalence of infection was 41.2% for Rainbow Trout caught while electrofishing compared to 41.8% for Rainbow Trout caught while angling. We did not find a difference in short‐term survival of infected and uninfected Rainbow Trout after the stress test (4 ‐7 days after the test). We did not observe consequences of infection by parasitic copepods on vulnerability to angling or short‐term survival of Rainbow Trout in Birch Creek. However, conditions (i.e. low‐level of infection and relatively small fish) may not have been conducive to detecting differences in performance metrics; further testing at higher intensity of infection and with larger fish may uncover negative impacts of parasitic copepods on Rainbow Trout.","PeriodicalId":19263,"journal":{"name":"North American Journal of Fisheries Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135248056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Releasing water from off‐channel storage into small streams is a novel restoration strategy to offset impacts from anthropogenic flow alteration on salmonid fishes. To date, no studies have evaluated the ecological effects of small‐scale flow augmentations. Here, we quantify the effects of one such augmentation project on habitat connectivity, water quality, invertebrate drift, juvenile salmonid movement and survival. Our study took place in a Northern California stream and included an unusually wet summer (2019) and a more typical dry summer (2020). We found that differences in ambient streamflows between the two years mediated the physical and ecological effects of a 13.9 L/s augmentation treatment. In the dry year, habitat connectivity and dissolved oxygen markedly increased at sites > 1.5 km downstream from the point of augmentation, whereas during the wet year effects on those variables were negligible. In both years, invertebrate drift marginally increased following augmentation. Inter‐pool movement of wild juvenile steelhead ( Oncorhynchus mykiss ) and stocked Coho Salmon ( O. kisutch ) increased following augmentation during the dry summer but not the wet summer. Flow augmentation increased the survival probability for salmonids, with a larger effect during the dry summer (24% higher survival for Coho Salmon and 20% higher for steelhead), than during the wet summer (when no effect was observed for steelhead survival and Coho Salmon survival increased by 11%). This study indicates that appropriately designed small‐scale flow augmentations can improve conditions for rearing salmonids in small streams, particularly during dry years. More broadly, it provides empirical evidence that efforts to restore summer streamflow in small, salmon‐bearing streams can yield significant ecological benefits.","PeriodicalId":19263,"journal":{"name":"North American Journal of Fisheries Management","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135343954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strong avoidance responses to underwater sound and electricity have been shown to facilitate herding and mass removal of these fish. We conducted a telemetry study on a closed population of Silver Carp (i.e., 10 telemetered fish) to assess fine‐scale movement responses to herding stimuli. Two herding boats traveled along bank‐to‐bank transects through the study area (longitudinal progression rate = 0.37 m/s) emitting sound and electricity (“combination technique”) or no added stimuli (“control”). The combination technique was most effective in terms of increasing fish presence (2.2 x the control) in the refuge‐zones when herding had concluded and effective range (i.e., fish reaction distance; 1.6 x the control) relative to the herding boats. Fish median (~1 m/s) and maximum (~2 m/s) swimming velocity was relatively stable across fixed effects, except for the negative influence of water depth on maximum velocity. Water depth also exhibited a negative effect on fish reaction distance. Our results suggest effective range of the combination technique was conservatively 200 m (~20 dB re 1 μPa > ambient level) when accounting for water depth in the study area. Herding deployments less than 1 m/s (longitudinal progression) could control fish passing and maintain fish movements towards an intended location.

Boat identification numbers, positioned near the bow and present by law, were used as ‘tags’ in the analysis. Complete trip creel interviews at the sole access point provided information on trip characteristics. The long‐term mark‐recapture analysis of individual angling parties showed travel distance had a significant negative effect on party persistence among years and visitation within years. The distance effect was strongest for visitation, with visitation having a more negative relationship with distance than persistence. Persistence in the lake trout fishery was insensitive to fuel costs while the fuel cost covariate had a small though significant and negative effect on visitation. Time‐varying CJS models were ranked low with little model weight indicating the distance effect estimated for Lake Opeongo was a general phenomenon and did not vary by year.

Acute and chronic laboratory temperature tests have been used to develop protective thermal criteria, but these methods do not allow for testing the lethality of temperature interactions with other stressors. For instance, fish density and temperature interactions are likely to occur during low‐flow periods with high densities of fish stranded in a stagnant pool; but standard thermal tests only included one fish.We examined the effect of two acclimation temperatures that represent field temperatures (8°C and 18°C) on hatch success and larval survival, and the critical thermal maximum (CTMax) and minimum temperatures (CTMin). We then investigated how the interaction of density (n = 1, n = 10, n = 25 fish per 2 L) and temperature influence CTMax or CTMin.We found maximum egg hatch success and larval survival at 18°C and the temperature range for Bluehead Sucker larvae at 18°C was 7.2 ± 1.6°C to 32.1 ± 2.4°C. However, when the density of the larvae was high (n = 25 per 2 L) the upper thermal limit significantly decreased by 5.9°C.Our results indicate higher fish densities negatively affect the tolerance of the fish to increased temperature.
