Trends in Abundance and Biological Characteristics of Chum Salmon
Chum salmon are the second most abundant salmon in the North Pacific Ocean. In the 1930s, chum salmon were abundant along the Russian coast and in British Columbia. The total catch of chum salmon was small from the late 1940s into the 1970s but increased in the 1980s, reaching historically high levels from the 1990s to the present. Ocean distribution of chum salmon is affected by sea surface te...
متن کاملTrends in Abundance and Feeding of Chum Salmon in the Western Bering Sea
Results from surveys of the western Bering Sea and adjacent Pacific epipelagic waters, performed by TINRO-Centre are reported. Surveys of the nekton community were conducted from 1986 through 2005, annually. Information on the distribution of all chum salmon by age group, the abundance and biomass of chum salmon, and other fish in the western Bering Sea and adjacent Pacific Ocean water are repo...
متن کاملScale and Otolith Patterns Prove Growth History of Pacific Salmon
Scale and otolith patterns are frequently used for age determination, growth estimation, and stock identification of Pacific salmon. However, little information is available about their formation mechanism such as circulus, check in the scale, and growth increment in the otolith. I clarified the formation mechanisms of scale and otolith patterns by rearing experiments using juvenile sockeye and...
متن کاملSalmon in the Arctic and How They Avoid Lethal Low Temperatures
With climate change, scientists and others are interested in the future of Pacific salmon in the Arctic. Chum, pink, sockeye, coho, and chinook salmon have been encountered in the Beaufort Sea, well within Canadian Arctic waters. Chum is the only salmon species regarded as natal to the Mackenzie River watershed, although both pink and chum salmon appear to be natal to Alaska’s North Slope river...
متن کاملPopulation structure of chum salmon (Oncorhynchus keta) across the Pacific Rim, determined from microsatellite analysis
Delineation of phylogenetically and adaptively distinct groups in the distribution of chum salmon around the Pacific Rim may lead to conservation of genetic diversity through an understanding of the origin and the evolutionary processes promoting and maintaining genetic differentiation. An evaluation of genetic variation in describing the population structure of salmonids, is a key component in...
