The effects of (ip, 10 injections over 20 days) of melatonin (75 μg 100 g−1 BW), the serotonin (5-HT)-synthesis blocker, para-cholorophenylalanine (p-CPA, 10 mg 100g−1 BW) and the catecholamine-synthesis blocker, α-methylparatyrosine (α-MPT, 10 mg 100 g−1 BW) on gonadotropin (GTH) secretion and ovarian activity were studied in Heteropneustes fossilis during late preparatory to early prespawning (April–May). The treatments resulted in significant reductions of plasma GTH and estradiol-17β levels… CONTINUE READING
