Available in PDF, EPUB and Kindle. Book excerpt: Primary objectives includede in this report included monitoring water temperatures and discharge in the upper Big Hole River, monitoring Arctic grayling population abundance, and maintaining minimum instream flows. Severe drought returned to the Big Hole basin in 1994: runoff of sub-normal snowpack occured approximately six weeks betfore long-term average and lack of summer precipitation resulted in critically low stream flows. Discharge fell below the minimum "survival" flow of 20 cfs on 11 days in June due to irrigation withdrawals and on 55 days from August to October, primarily due to withdrawals of stock water. Water temperatures reached lethal levels in late July, resulting in an extensive fish kill. Attempts to preserve instream flows included eliciting cooperation from water users and providing alternative means of wattering cattle. The grayling spawning populatrion was lightly sampled, but age structure was balanced with the bulk of pawners age 3 and 4. Spawning success appeared to be good as indicated by the catch-per-effort of young-of-the-year graling in Fall suverys. Fall population surveys in the Wisdom sectio indicated an increase in grayling abundance to 65 +/- 50 age 1+ per mile. Age structure was well balanced. Investigations of the fall migration into Deep Creek were inconclusive. Suveys of grayling released into Skinner MEadows indicated that limited numbers returned to the release site after wintering wlsewhere. The Axolotl Lake reserve brood was characterized and gametes were collected.

Book Synopsis Fish Conservation by : Gene S. Helfman
Download or read book Fish Conservation written by Gene S. Helfman and published by Island Press. This book was released on 2007-07-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fish Conservation offers, for the first time in a single volume, a readable reference with a global approach to marine and freshwater fish diversity and fishery resource issues. Gene Helfman brings together available knowledge on the decline and restoration of freshwater and marine fishes, providing ecologically sound answers to biodiversity declines as well as to fishery management problems at the subsistence, recreational, and commercial levels. Written in an engaging and accessible style, the book: considers the value of preserving aquatic biodiversity offers an overview of imperiled fishes on a taxonomic and geographic basis presents a synthesis of common characteristics of imperiled fishes and their habitats details anthropogenic causes of decline examines human exploitation issues addresses ethical questions surrounding exploitation of fishes The final chapter integrates topics and evaluates prospects for arresting declines, emphasizing the application of evolutionary and ecological principles in light of projected trends. Throughout, Helfman provides examples, explores case studies, and synthesizes available information from a broad taxonomic, habitat, and geographic range. Fish Conservation summarizes the current state of knowledge about the degradation and restoration of diversity among fishes and the productivity of fishery resources, pointing out areas where progress has been made and where more needs to be done. Solutions focus on the application of ecological knowledge to solving practical problems, recognizing that effective biodiversity conservation depends on meeting human needs through management that focuses on long term sustainability and an ecosystem perspective.
