Abstract
Yearling steelhead trout held in fresh water at cold temperatures (6.5° or 10°C) showed an increase in gill microsomal Na+, K+-stimulated adenosine triphosphatase activity during parr-smolt transformation, whereas trout held in warm water (15° or 20°C) did not. Adenosine triphosphatase activity increased and other indications of transformation were observed in fish transferred from warm to cold water, whereas the reverse occurred on transfer from cold to warm water.Keywords
