Abstract
These studies concerned the changes in gonadotropin (GtH2) blood plasm a levels during a 24 h period in mature female carp during the spawnin g season (L:D=16:8). The aim of this research is to clarify whether th e pineal gland is implicated in circadian rhythm of of GtH2 release in the mature carp females. The result showed that the pinealectomy did not affect neither the level nor the pituitary GtH2 release rhythmicit y, and its amplitude and acrophase. Probably pineal gland does not exe rt a major influence on circadian organization of GtH2 release in the carp.
