EA Preliminary Study on Domestication of Bluespotted Snakehead (Channa Lucius, Channidae) in Concrete Tank

Abstract

This study aim to gain insight into the domestication of Channa lucius female kept in a concrete tank as much as four plots of each size 200×200×75 cm. C. lucius each concrete tank maintained by four females with an average weight of 300 ± 20 g/individual and four males with an average weight of 500 ± 50 g/individual. Treatment in this experiment consisted of four groups are control group (injection 0.9 NaCl) and exposed to 100 μg/kg body weight, 150 μg/kg body weight and 200 μg/kg body weight of LHRHa hormone preparations. Dose level best to increase the reproductive potential of C. lucius was 200 μg/kg body weight with time reaching a matured gonads 62 ± 12 days, fecundity was 2,617 ± 250 eggs/spaw, egg diameter 1.87 ± 0.02 mm, the survival embryo 85.92 ± 0.52% and hatching rate 82.41 ± 0.60%. Dose level of LHRHa was significantly (p<0.05) with time mature gonadal, fecundity and eggs diameter. Whereas hatching rate and embryo survival not significantly (p>0.05) between treatments, but significantly (p<0.05) different from the control group.
