Plasma levels of the hormones insulin and insulin-like growth factor-I (IGF-I) were assessed as indices of growth for individual juvenile coho salmon Oncorhynchus kisutch. Smolts were tagged in April, introduced to seawater in May, and reared at two

Coho salmon Oncorhynchus kisutch from the Strait of Georgia were used to test the hypothesis that slower growing fish in their first ocean year had lower survival over the late fall and winter than faster growing fish. The Strait of Georgia provided

The second paper evaluating the environmental risks associated with the culture of Atlantic salmon in the Pacific Northwest addresses organic wastes released from net-pens. It begins with the minor effects caused by dissolved nutrients from organic w

Salmon farms in British Columbia now typically produce over 2000 mt of fish during each 18- to 24-month production cycle. An 18-month study of Stolt Sea Farms' Arrow Pass farm was undertaken in 1996 to examine the spatial and temporal extents of chem

We hypothesise that salmon year class strength is determined in two stages during the first year in the ocean. There is an early natural mortality that is mostly related to predation, which is followed by a physiologically-based mortality. Juvenile s

The relationship between smoltification and smolt-to-adult return (SAR) of spring chinook salmon Oncorhynchus tshawytscha from the Deschutes River, Oregon, was examined for four release groups in each of three successive years. Fish were reared, mark

Atlantic salmon were reared in fresh water at ambient temperature or under conditions of constant 11°C temperature from November to April. One of the ambient temperature groups was not fed during November and December in order to produce small fish

Both yearling and underyearling (zero-age) coho salmon in fresh water showed spring- and/or summer increases in plasma thyroid hormone concentrations. The peak in plasma thyroxine (T 4 ) was larger and occurred earlier during the spring in yearling f
