Abstract
The pituitaries of male and female common carps were subjected to the treatment with recombinant human activin A. Basal LH secretion decreased in females during wintering, but stimulated basal and sGnRH-induced LH secretion during ovulatory period. It stimulated LH secretion in males during wintering, but not during spawning, suggesting sex-specific effect of activin on LH secretion in common carp.
