Book Synopsis Alaska Herring History by : James Mackovjak
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.

Book Synopsis Distribution, Relative Abundance, and Movement of Skipjack Tuna, Katsuwonus Pelamis, in the Pacific Ocean Based on Japanese Tuna Longline Catches, 1964-67 by : Walter M. Matsumoto
Download or read book Distribution, Relative Abundance, and Movement of Skipjack Tuna, Katsuwonus Pelamis, in the Pacific Ocean Based on Japanese Tuna Longline Catches, 1964-67 written by Walter M. Matsumoto and published by . This book was released on 1975 with total page 802 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catch data of the Japanese tuna longline fishery from 1964 to 1967 were analyzed to determine the distribution, abundance, and movement of skipjack tuna, Katsuwonus pelamis, in offshore waters of the Pacific Ocean. Large skipjack tuna, as well as larvae, were found to be concentrated mainly in the east central equatorial Pacific. Movement of skip-jack tuna stocks was determined by following the shifting of high-CPUE (catch per unit effort) cells from one quarter to the next. The apparent movement of skipjack tuna stocks in the Pacific appeared to coincide with the circulation of the major ocean currents; counterclockwise in the southern hemisphere and clockwise in the northern hemisphere, except in the eastern Pacific where the current flow is counterclockwise. The movement patterns of high CPUE suggested that skipjack tuna adults or their progeny could move from one area to the next. The movement pattern was used also to determine the probable migratory routes followed by skipjack tuna tagged in the eastern Pacific and recovered near the Hawaiian and Christmas islands.
Book Synopsis Seasonal abundance and distribution of zooplankton, fish eggs, and fish larvae in the eastern Gulf of Mexico, 1972-74 by : Edward D. Houde
Download or read book Seasonal abundance and distribution of zooplankton, fish eggs, and fish larvae in the eastern Gulf of Mexico, 1972-74 written by Edward D. Houde and published by . This book was released on 1976 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zooplankton volumes and abundance of fish eggs and fish larvae were determined for stations on 12 cruises to the western Florida continental shelf. Contour charts of zooplankton volumes and of ichthyoplankton abundance are presented. A marked seasonality was observed for zooplankton and ichthyoplankton, highest zooplankton volumes and ichthyoplankton abundance occurring during May through September. Zooplankton volumes were highest and spawning by fishes most intense in the northern half of the study area (north of lat. 27°15ʹN). Fish larvae abundance (number under 10 m2 of sea surface) was highest at stations deeper than 50 m. Simple correlations among biological variables showed fish egg abundance-zooplankton volumes and fish egg abundance-fish larvae abundance to be positively correlated on most cruises. No clear relationships were observed between abundance or concentration of biological variables and temperature or salinity.
Book Synopsis Seasonal Distributions of Larval Flatfishes (Pleuronectiformes) on the Continental Shelf Between Cape Cod, Massachusetts, and Cape Lookout, North Carolina, 1965-66 by : W. G. Smith
Download or read book Seasonal Distributions of Larval Flatfishes (Pleuronectiformes) on the Continental Shelf Between Cape Cod, Massachusetts, and Cape Lookout, North Carolina, 1965-66 written by W. G. Smith and published by . This book was released on 1975 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Larval flatfishes, representing 4 families, 17 genera, and 15 species, were identified from collections taken during a 1-yr survey designed to locate spawning grounds and trace dispersion of fish eggs and larvae on the continental shelf. Most flatfishes began spawning in the spring, a time of marked seasonal temperature change. The seasonal distribution of larvae indicated that: 1) bothids had longer spawning seasons than pleuronectids; 2) pleuronectids spawned largely in the northern half of the survey area during the spring; 3) most bothids spawned in the southern half, beginning in spring and continuing through early fall; 4) although cynoglossids spawned incidentally off North Carolina, most of their larvae were transported into the survey area from spawning grounds south of Cape Lookout; 5) the few representatives of the family Soleidae originated south of Cape Lookout; 6) spawning that began in the spring proceeded from south to north as the season progressed, but spawning that began in the fall proceeded from north to south, suggesting that the onset of spawning is triggered by spring warming and fall cooling; 7) most species spawned within a relatively narrow range of temperature; 8) salinity had no apparent influence on spawning.
