Atlantic salmon (Salmo salar L.) populations have declined rapidly in recent years across all
geographical ranges with populations becoming extinct within certain areas. Direct …

Salmo salar post‐smolts were reared in seawater under controlled laboratory conditions for
12 weeks. The fish were exposed to three constant temperature treatments (15, 10.5 and 6° …

The precision of growth estimates based on fish scales often remains uncertain because of
withinindividual variation in scale size and scale patterns, and also due to measurement …

Scale circuli yield valuable information about the life history, age, and growth of a fish.
However, because circuli formation is influenced by somatic growth, the rate at which circuli …

Variation in circulus spacing on the scales of wild Atlantic salmon is indicative of changes in
body length growth rate. We analyzed scale circulus spacing during the post‐smolt growth …

To address population declines, many salmon populations are supplemented with hatchery-
bred fish. Little is known about how growth performance of hatchery-bred and wild salmon …

Juvenile steelhead Oncorhynchus mykiss from a northern California Central Valley
population were reared in a controlled laboratory experiment. Significantly different rates of …

The abundance of wild Atlantic salmon (Salmo salar) has declined since the 1970s. The
major reason for the recent decline appears to be increased marine mortality. Before 1970s …

Fish scales have increasingly been used to quantify annual and seasonal growth trends and
in efforts to relate growth to environmental conditions. Understanding the timing of formation …

Indices of the monthly post‐smolt growth of three maturity groups of Atlantic salmon Salmo
salar from the Drammen River in Norway were examined. Scale samples were collected …
