the seasonal changes in the gonadotrophin-release-inhibitory activity of dopamine and responsiveness to gonadotrophin-releasing hormone were investigated by determining the effects of injection of pimozide , a dopamine receptor antagonist , des-gly10 [ d-ala6 ] lh-rh ethylamide ( lrh-a ) , or the combination of pimozide plus lrh-a on serum gonadotrophin ( gth ) levels of goldfish , held at 12 or 20 degrees c , at different stages of gonadal development .
