Download or read book Yakutat Salmon Escapement Surveys 2022 2024 written by Richard A. Hoffman (Biologist) and published by . This book was released on 2022 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Alaska Department of Fish and Game, Division of Commercial Fisheries, monitors annual spawning escapements of Pacific salmon within the Yakutat Management Area. Aerial and ground surveys are methods used to develop escapement estimates of sockeye Oncorhynchus nerka, Chinook O. Tshawytcha, and coho O. kisutch salmon. Inseason assessment of salmon runs plays an important role in the management of the Yakutat commercial, subsistence, and sport fisheries where harvest adjustments can be made in order to meet escapement goals. This report provides operational guidelines for the locations and methods for conducting systematic surveys for obtaining peak index counts of local salmon stocks.

Download or read book Operational Plan Sockeye Salmon Escapement Studies at the Russian River 2023 2026 written by Jenny L. Gates and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Russian River sockeye salmon escapement assessment project, which began in 1962, is one of the oldest stock assessment projects in the state of Alaska. During 2023–2026, the Russian River weir will be operated annually from early June through the first 7 to 10 days of September. All species of fish seen passing the weir through the fish chute will be enumerated daily. Sampling of sockeye salmon for age, sex, and length data will be done each Friday, and the sample size each week will be based on the previous week’s fish passage. Sockeye and Chinook salmon spawning downstream of the Russian River weir to the confluence of the Russian River and the Kenai River will be assessed by a foot survey during the fourth week of August. Multiple foot surveys will also be conducted from mid-May to 10 June to assess spawning rainbow trout.
Download or read book Operational Plan Southeast Alaska Marine Boat Sport Fishery Harvest Studies 2023 written by Michael Jon Jaenicke and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine boat sport anglers throughout Southeast Alaska target and harvest Chinook salmon Oncorhynchus tshawytscha, coho salmon O. kisutch, Pacific halibut Hippoglossus stenolepis, lingcod Ophiodon elongatus, a variety of rockfish species Sebastes spp., and sablefish Anoploploma fimbria primarily during April to September. Angler effort, catch, and harvest data will be collected from late April to early September from returning marine boat anglers at the following ports: Yakutat, Elfin Cove, Gustavus, Juneau, Sitka, Petersburg, Wrangell, Ketchikan, Craig, and Klawock. Harvest sampling will be used to collect biological samples and associated data to estimate the age, length, and genetic composition of the Chinook salmon harvest, and Chinook and coho salmon will be inspected for missing adipose fins, indicating the head should be removed to recover a coded wire tag. Contributions of hatchery and wild coded-wire-tagged stocks (both Chinook and coho salmon) to the sport harvest will be estimated for all sampled ports, and the wild mature component of the Chinook salmon harvest in Division of Commercial Fisheries Salmon District 108 (Petersburg-Wrangell) and District 111 (Juneau) will also be estimated. Biological data from harvested Pacific halibut (lengths), lingcod (lengths and sex), and rockfish (lengths) will be collected from guided and unguided marine boat anglers. The length data will be converted via established species-specific, length-weight relationships to estimate average weights by species and angler type.

Download or read book Rebuilding of Marine Fisheries Global review written by Serge Garcia and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Rebuilding depleted stocks is a central part of the fisheries governance agenda. By analysing the available literature, Part 1 of "Rebuilding of marine fisheries" provides a global review of the emergence of the rebuilding paradigm, its key concepts, the trends in fishery resources, and the empirical evidence available on stocks depletion, collapse and rebuilding. It addresses the bio-ecological, economic, and human dimensions of rebuilding or restoration of stocks, multispecies assemblages and habitats/ecosystems and touches on the need for rebuilding at the whole sector level when depletion has become widespread and chronic. The human imensions of stocks and fisheries are given particular attention, looking at conflicting objectives, the bio-economy of rebuilding, its costs and benefits, and the distributional effects of the related reform among actors with their potential social consequences in the short and long terms. Governance is addressed in detail: legal and policy frameworks; rationale and objectives of a rebuilding regime; alternative rebuilding strategies; reference values and protocols; regulatory time-frames; risk management and harvest control rules; impacts of climatic oscillations; management tool-box; implementation guidance and performance evaluation. The document ends with a review of the determinants of success of a rebuilding programme."--Publisher's description for part 1.

Available in PDF, EPUB and Kindle. Book excerpt: Mathematical modelling is widely used in ecology and evolutionary biology and it is a topic that many biologists find difficult to grasp. In this new textbook Marc Mangel provides a no-nonsense introduction to the skills needed to understand the principles of theoretical and mathematical biology. Fundamental theories and applications are introduced using numerous examples from current biological research, complete with illustrations to highlight key points. Exercises are also included throughout the text to show how theory can be applied and to test knowledge gained so far. Suitable for advanced undergraduate courses in theoretical and mathematical biology, this book forms an essential resource for anyone wanting to gain an understanding of theoretical ecology and evolution.

Download or read book Wildlife and Recreationists written by Richard L. Knight and published by Island Press. This book was released on 2013-04-22 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildlife and Recreationists defines and clarifies the issues surrounding the conflict between outdoor recreation and the health and well-being of wildlife and ecosystems. Contributors to the volume consider both direct and indirect effects of widlife-recreationist interactions, including: wildlife responses to disturbance, and the origins of these responses how specific recreational activities affect diverse types of wildlife the human dimensions of managing recreationists the economic importance of outdoor recreation how wildlife and recreationists might be able to coexist The book is a useful synthesis of what is known concerning wildlife and recreation. More important, it addresses both research needs and management options to minimize conflicts.
