[Influence of captivity on the pituitary gonadotropic area and correlative modifications of the sexual cycle in Serranus cabrilla Linné (Teleosts, Serrinidae)].

In Serranus cabrilla, ventral pars distalis contains characteristic gonadotropic cells which present morphological and functional variations in relation with sexual cycle and captivity. Their secretory activity, particularly marked when confinement begins before spawning, and gonads evolution are examined within various experimental conditions.
