The induction of laserpuncture on the reproductive acupoint of catfish can accelerate gonadotropin hormone formation from the pituitary especially gonadotropin II (GTH-II) which has a role in the final stage of oocyte maturation, ovulation and spawning stimulation. The purpose of this study is to evaluate the effects of laserpuncture induction toward the egg quality from crossbreeding catfish male var. Paiton and female var. Sangkuriang. The egg quality was measured by the following parameters: fertilization rate (FR), egg hatching rate (HR), and larvae survival rate (SR). The research treatments were conducted using two levels along with eight repetitions. The results show that the crossbreed catfish using laserpuncture induction affected the parameters by increasing the mean value of fertilization rate, egg hatching rate and larvae survival rate significantly (P < 0.05) compared with mean value of fish without induction. This study concluded that laserpuncture induction on the crossbreeding between broodstock of male catfish var. Paiton and female var. Sangkuriang will increase FR, HR and SR. © 2015 National Institute of Oceanography and Fisheries.
