Induction of ovulation and spawning in the catfish, Clarias batrachus (L.) by prostaglandin F2 alpha.
Administration of low doses of prostaglandin F2 alpha (PGF2 alpha), i.e. 10 and 100 ng/g b.wt, was ineffective in inducing ovulation and spawning in mature catfish. However, doses of 200 ng/g b.wt of PGF2 alpha elicited partial response, and 500 ng/g b.wt of PGF2 alpha induced profuse ovulation and spawning similar to that induced by administration of human chorionic gonadotropin (HCG).
