Available in PDF, EPUB and Kindle. Book excerpt: Aerial surveys to observe milt clouds produced by spawning herring in Southeastern Alaska waters hold promise as a method for assessing the extent of spawn deposition. Flights are conducted at altitudes of 500 to 700 feet and at cruising speeds of 120 knots. The mileage of beach utilized for spawning is recorded on reduced prints of navigation charts. The surveys have resulted in the discovery of 80 previously unreported spawning beaches. Observations during these preliminary flights have also added valuable information on the time of spawning and the physical characteristics of the beaches.

Download or read book Herring and People of the North Pacific written by Thomas F. Thornton and published by University of Washington Press. This book was released on 2021-01-31 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herring are vital to the productivity and health of marine systems, and socio-ecologically Pacific herring (Clupea pallasii) is one of the most important fish species in the Northern Hemisphere. Human dependence on herring has evolved for millennia through interactions with key spawning areas—but humans have also significantly impacted the species’ distribution and abundance. Combining ethnological, historical, archaeological, and political perspectives with comparative reference to other North Pacific cultures, Herring and People of the North Pacific traces fishery development in Southeast Alaska from precontact Indigenous relationships with herring to postcontact focus on herring products. Revealing new findings about current herring stocks as well as the fish’s significance to the conservation of intraspecies biodiversity, the book explores the role of traditional local knowledge, in combination with archeological, historical, and biological data, in both understanding marine ecology and restoring herring to their former abundance.

Download or read book Alaska Herring History written by James Mackovjak and published by University of Alaska Press. This book was released on 2022-07-18 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alaska Herring History is a thoroughly researched, well-documented, and comprehensive chronicle of Alaska’s herring fisheries. Author James Mackovjak describes the evolution of these fisheries from the late nineteenth century to the present, including harvest, processing, markets, and sustained-yield management considerations. The book is divided into three parts based on the purposes for which herring have been harvested. Part I is a history of the reduction (fertilizer/fish meal/fish oil) and cured (salted) herring industries and the bait-herring fisheries; part II is a history of the roe-herring fisheries in Southeast Alaska, Prince William Sound, Kodiak Island, lower Cook Inlet, Togiak, and Norton Sound; and part III is a history of the herring spawn-on-kelp industry. Historical and contemporary photos and illustrations—as well as graphs and charts that help summarize the development and, in some cases, the demise of the fisheries—augment this detailed look at the evolution of Alaska's herring fisheries. Balancing scientific details, historical facts, and personal anecdotes from experts in the field, Alaska Herring History will be of interest to historians, social scientists, biologists, and fishery managers and makes an important contribution to Alaska fisheries literature.
