Abstract

The present study was aimed to perform induced breeding and to observe embryonic and larval development stages of Comet gold fish (Carassius auratus) in mature males and females by administering hormone of double dose in female and a single dose in male by intramuscular injection of ovaprim at a dosage of 0.5, 0.7, 1.0 and 1.2 ml/kg body weight. Spawning was observed six hours after the injection at ambient temperature (18-22oC). Fertilization rate of eggs were found 50.34, 51.47, 47.30 and 48.24 % respectively with the response of 0.5, 0.7, 1.0 and 1.2 ml/kg of ovaprim. Hatching rates were found 44.35, 43.79, 39.83 and 36.00 % respectively with the same doses. The fertilized eggs were adhesive, translucent and spherical in shape with diameter ranging between 0.9- 1.0 mm and were whitish in color. The hatchlings were transparent and measured 1.3- 1.7 mm of total length with a large oval head, a well defined yolk sac and a short tail. At approximately seven weeks the larvae attained an average total length of 15.2 mm and the fry had acquired some scales, visible pigmentation was general, and the body essentially resembled the adult. Due to good response to synthetic hormone (ovaprim), considerable fertilization and hatching rate, short embryonic period and fast larval development it is possible to conduct breeding program of this species commercially and is suitable for commercial culture.
