Special Section: Hatcheries and Management of Aquatic Resources (HaMAR)

The American Fisheries Society (AFS) has routinely assessed the contributions of hatcheries to natural resource management, and issued recommendations to guide managers in the best uses of hatchery-origin fish. In response to changes in fisheries management policy, new information on supplementation and rehabilitation, and fisheries issues that had arisen, AFS undertook a new assessment in.. read more →

Climate Change Adaptation and Restoration of Western Trout Streams: Opportunities and Strategies

Climate Change Adaptation and Restoration of Western Trout Streams: Opportunities and Strategies Climate change is contributing to the severity and rate of stream degradation by changing the timing of peak flows, altering flow regimes, creating more frequent and intense disturbances, and increasing stream temperatures. Herein we describe three case studies of trout stream adaptation that.. read more →

AFS Letter on Wisconsin Budget Situation

Proposed Budget Undermines Critical Fish and Wildlife Research and Training Programs Wisconsin’s fish and wildlife resources are an immense treasure for the state and its residents. Nearly 2.5 million residents and another 1 million non-residents (over 16 years of age) participate in fishing, hunting or wildlife associated recreation in Wisconsin and contribute substantially to the.. read more →

Transactions Journal: A Sex-Determining Gene (sdY) Assay Shows Discordance between Phenotypic and Genotypic Sex in Wild Populations of Chinook Salmon

Abstract Sex is determined genetically in most fishes, but the gene responsible for sex determination is not known for the vast majority of fish species, including Chinook Salmon Oncorhynchus tshawytscha. The purpose of this study was to characterize a putative sex-determining gene (“sexually dimorphic on the Y-chromosome” [sdY] gene) in Chinook Salmon and develop a.. read more →

Transactions Abstract: Morphometric Contribution to the Detection of Introgressive Hybridization in the Endangered Owens Tui Chub in California

Abstract The Owens Tui Chub Siphateles bicolor snyderi has become endangered by introgressive hybridization with the Lahontan Tui Chub S. bicolor obesa since the 1960s. Adequate conservation strategies require prior identification of pure populations, which is usually difficult because the diagnostic features presented in the formal subspecies description do not always allow unequivocal determination of.. read more →

• Transactions Abstract: Quantifying Avian Predation on Fish Populations: Integrating Predator-Specific Deposition Probabilities in Tag Recovery Studies

Abstract Accurate assessment of specific mortality factors is vital to prioritize recovery actions for threatened and endangered species. For decades, tag recovery methods have been used to estimate fish mortality due to avian predation. Predation probabilities derived from fish tag recoveries on piscivorous waterbird colonies typically reflect minimum estimates of predation due to an unknown.. read more →

• Transactions Abstract: Does Catch-and-Release Angling Alter the Behavior and Fate of Adult Atlantic Salmon During Upriver Migration?

Abstract To reproduce, Atlantic Salmon Salmo salar return to freshwater rivers and migrate upriver to spawning areas. This migration is the basis for recreational fisheries, which for conservation reasons are increasingly characterized by catchand-release angling. The effectiveness of catch and release for Atlantic Salmon conservation is contingent on the ability of individuals to recover from.. read more →

• Transactions Abstract: Reproductive Complexity in a Long-Lived Deepwater Fish, the Blackgill Rockfish

Abstract Fish populations are regulated by complex biological processes and ecosystem interactions. To inform stock assessments and management models, a clear understanding of a species’ reproductive biology is necessary, particularly in long-lived species, for which estimates of sustainable yield are sensitive to such parameters. Deviations from traditional views of iteroparity in marine fishes (e.g., prolonged.. read more →
