abstract
The present study was aimed to perform induced breeding of Telescopic eye gold fish (Carassius auratus auratus) in captivity by administering WOVA-FH hormone at different doses. The study was conducted during the period from January-March, 2018 at Chennai, Tamil Nadu for 3 months. All the breeding pairs were bred including control. Significant (<0.05) difference were observed in the success rate of spawning at different dose among treatments and in control. WOVA- FH at a dose of 0.7ml/kg and 1.4ml/Kg was found to be effective for male and female respectively with 74% fertilization rate, 82 % hatching rate and fecundity of 1185-1205 eggs/female. Variability in hormone dose induced resulted in variability in latency period (5-9hrs), fecundity (767-1205 eggs/female), fertilization rate (46-74%) and hatching rate (52-82%). The positive response to synthetic hormone (WOVA-FH) with considerable fecundity, fertilization and hatching rate makes it possible to conduct the breeding program of this species commercially and the method can be applicable for commercial culture.
