Stress, osmoregulation, and the hormone cortisol in yearling coho salmon, Oncorhynchus kisutch

Creator:

Redding, Joseph Michael

Abstract:

Freshwater (FW) and seawater (SW) acclimated yearling coho salmon, Oncorhynchus kisutch, were subjected to severe confinement stress in FW, SW, or a medium (1/3 SW) that was approximately isosmotic to the fish's blood. Chronic stress caused osmotic imbalances in FW and SW, but not in 1/3 SW. In SW, blood...

Physiology of interrenal function in juvenile coho salmon (Oncorhynchus kisutch) and effects of hatchery rearing practices

Creator:

Patino, Reynaldo

Abstract:

Periodic determinations of plasma hormone levels suggested that changes in interrenal activity are unrelated to changes in thyroidal or gonadal activity during development (smoltification) of juvenile coho salmon (Oncorhynchus kisutch). Moreover, in an experiment where fish were reared under various conditions of crowding and water inflow rate, it appeared that...
