| Description
| - The aim of the present study was to study spawning stimulation in artificial reproduction of females pikeperch (Sander lucioperca L.) using %22Chorulon%22 containing the human chorionic gonadotropin (hCG) and compare with %22Supergestran%22 containing a mammalian GnRH ([D-Ala(6)]GnRHProNhet) analogue. The females were divided into eleven experimental groups and injected with hCG at 250, 500, 750, and 1 000 IU kg(-1) body weight (BW) and mGnRHa at 1, 2.5, 5, 10, 25, and 50 mu g kg(-1) BW. In all treatments, a single intramuscular injection of hormone was performed. Control group was injected with 0.9 % NaCl, 0.9 cm(3) kg(-1) BW. The average percentages of ovulating females were 88.5 +/- A 12.3 and 80.8 +/- A 10.9 % in hCG- and mGnRHa-treated groups, respectively. The average diameter of eggs was 0.95 +/- A 0.06 and 0.98 +/- A 0.06 mm in hCG- and mGnRHa-treated groups, respectively. Neither ovulation rate nor diameter of egg was statistically differed among hormonally treated groups. Statistical difference was observed only in hatching rate, where the average were 73.6 +/- A 14.4 and 50.6 +/- A 17.7 % in hCG and mGnRHa-treated groups, respectively. Among hormonally treated groups, the best results were observed in groups treated with hCG at 500 and 750 IU kg(-1) and in groups treated with mGnRHa at 25 mu g kg(-1). No ovulation was observed in the control group. This study indicated successful ovulation in pikeperch using a single intramuscular injection of hCG or mGnRHa analogue.
