Download or read book Ecological Studies of Sockeye Salmon and Related Limnological and Climatological Investigations Brooks Lane Alaska 1957 written by Theodore R. Merrell and published by . This book was released on 1964 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological studies on the fresh-water phases of the life history of sockeye salmon and studies on related limnology and climatology were made at Brooks Lake, Alaska, in 1957. Data are presented and interpreted on adult sockeye salmon spawning distributions and behavior, age, sex, length, fecundity, and bear predation; on juvenile sockeye salmon ages, food, growth, migration from the lake, relative abundance, and distribution in the lake; and on climatological and limnological factors that may influence sockeye salmon behavior and abundance.

Download or read book Living Marine Resources written by Edwin S. Iversen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living Marine Resources provides a thorough, up-to-date introduction to all aspects of fisheries science. This clearly written text offers insight into a topic of increasing importance--the wise utilization and management of sea fisheries to maximize production without exceeding their carrying capacity. Adoption of the approaches presented will improve the conservation and management of the many world fisheries that are suffering from years of inefficient practices. The book is divided into five sections, beginning with an introduction to the ocean environment and the various resource species. Part two examines fisheries biology, including age, growth, fecundity, and mortality, enabling readers to appreciate yield models designed to give estimates of maximum sustainable yield and maximum economic yield. The third part covers gear, methods, and landings and includes material on the handling and processing of seafood as well as aquaculture. In part four, yield models are presented to introduce students to theories on population dynamics, stock assessment, and management. The book concludes with coverage of recreational fisheries, including socioeconomic importance, catch and effort research, management techniques, and their interface with commercial fisheries. Living Marine Resources is an invaluable introduction to the subject for advanced undergraduate and graduate students of fisheries science. In addition, the material presented will be valuable to fishery and social scientists, fishery officers and administrators, and students in biology, engineering, economics, and law.

This book was released on 1963 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Differences in hyoid teeth and spotting counts among samples from four related populations of Yellowstone cutthroat trout, Salmo clarki lewisi Girard, reached species and subspecies levels as defined by some workers. Body coloration varied significantly among fish in six spawning runs of Yellowstone Lake, Wyo. The use of coloration, spotting, and hyoid teeth counts in cutthroat trout for taxonomic purposes needs reevalution.
