Effects of Different Hypothalamic Peptides and Neurotransmitters on Gonadotropin and Growth Hormone Secretion in Common Carp (Cyprinus carpio L.)

Effects of different hypothalamic peptides and neurotransmitter on gonadotropin and growth hormone secretion in 1-year common carp at midrecrudenceses indicated that TRH,L-DOPA,MT,GABA,LHRH-A and T3 could significantly stimulate GtH secretion,but their affecting time and tone were different from each other.TRH and LHRH-A also have GH stimulatory actions.No effects have been found of L-DOPA,MT and GABA on serum GH secretion; T3 has inhibitory effect on GH release.
