Handling and confinement caused a steady increase in the plasma ACTH level in both coho salmon and rainbow trout. Within 2 min plasma ACTH levels had increased significantly, and by 30 min they were 5- to 8-fold higher than the basal ACTH level in unstressed fish. This type of stress also caused a pronounced elevation in plasma cortisol, which lagged behind the ACTH increase, although the degree of change was greater, the level rising between 20- and 50-fold. The plasma alpha-MSH level was… CONTINUE READING
