Effect of Ovaprim, Ovatide, HCG, LHRH-A2, LHRHA2+CPE and Carp Pituitary in Benni (Barbus sharpeyi) Artificial Breeding

The Barbus sharpeyi is a species of the genus Barbus of cyprinidae with local name"Benni" distributed in shadegan and horolazim GnRHA2-effectiveness of Ovaprim, Ovatide, GnRHA2, LHRH-A2, LHRHA2+CPE and Carp Pituitary on spawning success, Latency period, working fecundity, fertilization success and hatching rate. 56 fish were divided into 7 treatments and injected intramuscullary as follows. 4mg kg*1 b.w.of CPE as positive control, Propylene glycol as negative control, 0.5 mg kg*1b.w. of Ovaprim, 0.5 mg kg* 1b.w. of Ovatide, 1000 Iu kg*1b.w. of HCG, 10^g kg*1b.w. of LHRH-A2, 10^g+2 mg kg*1 b.w. of LRHa+CPE in double injection 10 h apart. Results showed that LRHa+CPE combination yielded 87.5% spawning success in comparison with HCG, Ovaprim, Ovatide, LRHa and CPE. None of fish were ovulated in the groups of negative contol, HCG and LRHa, while 3/8 fish were ovulated in the group of Ovaprim and Ovatide(37.5%). 6/8 fish were ovulated in the group of CPE(75%). Therefor, LHRHa+CPE combination can be effected comparison CPE or alone other hormones.
