Abstract
The effect of three native GnRH peptides, viz; salmon GnRH (sGnRH), mammalian
GnRH (mGnRH) and chicken GnRH II (cGnRH II), on spawning of the catfish Heteropneustes
fossilis (Bloch) was compared. D-Lys6sGnRH, was used as the control. The peptides were
synthesized by the Merrifield solid phase method, purified by HPLC and reconstituted in
saline. The fish were injected intramuscularly. cGnRH II was more potent than both sGnRH
and mGnRH in inducing spawning in this species of catfish. There was no significant difference
in the average diameter of the egg obtained using the three peptides
