Book Description
Sport-angler effort and harvest of Chinook salmon Oncorhynchus tshawytscha were estimated from a creel survey conducted at 2 distinct hatchery release sites along the Juneau shoreside from 1 June to 28 August 2022. This time period aligned with liberalized sport bag and possession limits targeting Alaska hatchery Chinook salmon production at a designated sport harvest hatchery area encompassing these 2 hatchery release sites as well as adjacent marine waters. Sport anglers harvested an estimated total of 2,628 Chinook salmon across both hatchery release areas, including 1,462 (SE = 207) at Macaulay Salmon Hatchery and 1,165 (SE = 259) at Fish Creek. The total Chinook salmon harvest observed at Macaulay Salmon Hatchery (1,462) included 1,383 (SE = 207) large and 80 (SE = 80) non-large fish. The total Chinook salmon harvest observed at Fish Creek (1,165) included 982 (SE = 221) large and 183 (SE = 55) non-large fish. Total effort (angler-hours) was estimated at 18,905, including 12,623 (SE = 629) at Macaulay and 6,282 (SE = 481) at Fish Creek. The stock composition based on genetic analysis revealed Chinook salmon harvested in these 2 distinct hatchery release areas were approximately 99% enhanced-origin fish from the Andrew Creek stock. Large Chinook salmon (defined as fish >28ʺ total length) dominated the total catch across both areas (approximately 84%). The age composition of large Chinook salmon harvested by sport anglers across both areas was dominated by age-1.3 fish (>80%). Residents comprised about 65% of all interviewed anglers.

Book Description
Sport anglers fishing from shore in the Juneau area of Southeast Alaska target and harvest Chinook salmon Oncorhynchus tshawytscha, primarily during April - August, the duration of which can be truncated due to wild stock management measures. Angler effort, catch, and harvest data will be collected from June through August 2022 from shore-based anglers at 2 prioritized locations in the Juneau area associated with Alaska hatchery release sites. 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. Chinook 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 to the sport harvest will be estimated for both locations.

Book Description
Haa Leelk'w Has Aan' Saaxu / Our Grandparents' Names on the Land presents the results of a collaborative project with Native communities of Southeast Alaska to record indigenous geographic names. Documenting and analyzing more than 3,000 Tlingit, Haida, and other Native names on the land, it highlights their descriptive force and cultural significance. With community maps, tables, and photographs, this book will be invaluable for those seeking to understand Alaska Native geographic perspectives. As Tlingits from the Hoonah Indian Association explain in the book: "Long before Russian, French, Spanish, and British explorers mapped and named the mountains and bays of the Huna Tlingit homeland, we identified special places in our own vibrant, descriptive ways. Tlingit place names reflect important natural resources, ancestral stories, sacred places, and major geological and historic events. Our place names describe more than just inanimate locations for we perceive the mountains, glaciers, and streams to be as alive and aware as ourselves. Rather, they capture the history, emotions, and stories of our enduring relationship with a living, evolving landscape." "The new benchmark against which all future work will be measured." -Richard Dauenhauer, author of Russians in Tlingit America "Thomas Thornton and his Tlingit colleagues show how 'grandparents' names on the land' provide exquisite scaffolding for human ecologies in North America's far northwest--a moral universe inhabited by a community of beings in constant communication and exchange. This book will be a resource for the ages." -Julie Cruikshank, author of Do Glaciers Listen? Local Knowledge, Colonial Encounters, and Social Imagination "Restoring Tlingit placenames and their meanings will root our people back in place and decolonize the landscape, and Thornton has provided us with a fundamental tool to do exactly that. Sh t--oghaa xhat ditee--I am grateful." -Lance A. Twitchell, Xh'unei, University of Alaska Southeast Thomas F. Thornton is senior research fellow and director of the Environmental Change and Management Program at the Environmental Change Institute, School of Geography and the Environment, University of Oxford He is the author of Being and Place among the Tlingit.

Book Description
Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Book Description
The Bowhead Whale: Balaena mysticetus: Biology and Human Interactions covers bowhead biology from their anatomy and behavior, to conservation, distribution, ecology and evolution. The book also discusses the biological and physical aspects of the Arctic ecosystem in which these whales live, with careful attention paid to the dramatic changes taking place. A special section of the book describes the interactions of humans with bowheads in past and present, focusing on their importance to Indigenous communities and the challenges regarding entanglement in fishing gear, industrial noise and ship strikes. This volume brings together the knowledge of bowheads in one place for easy reference for scientists that study the species, marine mammal biologists, but, equally important, for everyone who is interested in the Arctic. - Presents the only current book dedicated to this species - Includes short, high-impact chapters that make it possible to review all bowhead biology in one compact volume - Illustrated with never-before published photos of bowheads in their natural environment - Provides a platform for an in-depth understanding of indigenous whaling

Book Description
The book presents half a century's worth of Japanese-style fish and shellfish prints in full colour, by artist, scientist, and all-around fish-enthusiast Chris Dewees. We follow his evolution, from being exposed to the fascinating gyotaku style as a graduate student, to his current status as an internationally recognised master in the field. He documents his journey and growth by sharing fifty years of experiences and adventures. In recent years Dewees has done more writing, and these stories and poems are linked to his art.

Book Description
This is the ninth volume of ten in the The Natural History of the Crustacea Series. The chapters in this volume synthesize the diverse topics in fisheries and aquaculture. In the first part of the book, chapters explore worldwide crustacean fisheries. This section comes to a conclusion with two chapters on harvested crustaceans that are usually not within the focus of the mainstream fisheries research, possibly because they are caught by local fishing communities in small-scale operations and sold locally as subsistence activity. In the second part of the book, the authors explore the variety of cultured crustacean species, like shrimps, prawns, lobsters, and crabs. Chapters in the third part of the volume focus on important challenges and opportunities, including diseases and parasitism, the use of crustacean as bioindicators, and their role in biotechnology.
