Title

COMPARISION OF THE EFFECTIVENESS GNRHA HORMONE(OVA-FACT) AND CARP PITUITARY EXTRACT ON REPRODUCTION INDEXES OF BARBUS SHARPEYI

Pages

  70-80

Abstract

 Barbus sharpeyi in family Cyprinidae is an endemic fish of the Khozstan province of Iran. The Iranian Fisherie Organization (Shilat) produces up to 1-5 million fry (1-2 g b.w.) to restock the horal azem and lagoon Shadgan population annually. These fish are produced by artificial breeding using CARP PITUITARY EXTRACT (CPE). The objective of this study was to assay the effectiveness of a gonadotropin releasing hormone analogue (D-Ala6, Pro9-Net GnRH) in combination with the dopamine antagonist DOMPERIDONE (DOM) on spawning success, latency period, weight of stripped egg mass/weight of stripped egg mass+remnant ovaries, and fertilization success in Barbus sharpeyi. Seventy two fish were divided into 12 groups and injected intraperitoneally as follows: 5 mg/kg, b.w. of CPE as positive control, GNRHA and DOM 30 jlg/kg, b.w. double injection (10-90%) 24 h apart. Propylene glycol injected fish were used as negative controls. The results showed that the GNRHA and DOM in two injection lead to higher spawning success and weight of stripped egg mass/weight of stripped egg mass, and fertilization success and spawning rate and latency period in comparison with positive control (P <0.05), while no significant differences inhaching percent and embryo viability and masuring egg were found ( P<0.05). Therefore, it can be concluded that like many other cyprinids, dopamine inhibitory tone is active in Barbus sharpeyi and it is necessary to combine GNRHA with a dopamine antagonist for spawning induction.
