Oncorhynchus kisutch

Description Body fusiform, streamlined, laterally compressed, usually 18 to 24 in. (457 to 610 mm) in length and 8 to 12 lb in weight as marine adults and 10.8 to 25.8 in. (279 to 656 mm) fork length in Great Lakes freshwater populations body depth moderate, greater in breeding males. [Pg.106]

Color Adults in ocean or Great Lakes are steel-blue to slightly green on dorsal surface, sides brilliant silver, ventral surface white, small black spots on back, sides above lateral line, base of dorsal fin, and upper lobe of caudal fin. [Pg.106]

Distribution This species occurs naturally only in the Pacific Ocean and its tributary drainage. It is known in fresh water in North America from Monterey Bay, CA (in the sea infrequently to Baja California) to Point Hope, Alaska. In Asia, it occurs from the Anadyr River, USSR, south to Hokkaido, Japan. [Pg.106]

Biology Adults migrate from the sea or lake late in the season and over a prolonged period. Spawning is from early September to early October segregation into summer and autumn, or autumn and winter runs is more apparent in Asia than in North America spawning takes place in swifter water of shallow, gravely areas of river tributaries from October to March, but usually October to November or November to January in N. America. [Pg.106]

Toxicity Testing Species can be used as a model salmonid. [Pg.106]

Lead is toxic to all phyla of aquatic biota, but its toxic action is modified by species and physiological state, and by physical and chemical variables. Wong et al. (1978) stated that only soluble waterborne lead is toxic to aquatic biota, and that free cationic forms are more toxic than complexed forms. The biocidal properties of soluble lead are also modified significantly by water hardness as hardness increases, lead becomes less bioavailable because of precipitation increases (NRCC 1973). In salmonids, for example, the toxicity and fate of lead are influenced by the calcium status of the organism, and this relationship may account for the reduced effects of lead in hard or estuarine waters. In coho salmon (Oncorhynchus kisutch), an increase in waterborne or dietary calcium reduced uptake and retention of lead in skin and skeleton (Varanasi and Gmur 1978). [Pg.288]
