Changes in Physiological Indicators and Behavioral Responses Induced by Pinealectomy in Rainbow Trout (Salmo irideus)
ABSTRAKT
There were the darkening of skin, decreased motor activity, disrupted phototaxis, and disturbed schooling behavior as the consequences of surgical destruction of the pineal organ in females of rainbow trout. The numbers of polymorphous-nuclear leukocytes in the blood and oocytes at higher stages of their maturity also declined. Taking into account the multiform participation of pineal secretion in regulation of reproductive function and other processes in the organism, the authors believe that it is possible to stimulate or artificially inhibit the pineal activity by regulating the light intensity for the purposes of growth acceleration or increasing the immune reactivity of fishes.
