An experiment was conducted to know the effect of different dosages of HCG implanted hormonal pellets on gonadal maturation of striped murrel Channa striata. Sixty four broodfish of Channa striata (500-700g ) were randomly distributed in 8 tanks, in duplicates, following a completely randomized design. Each tank (8 m2) contained 8 numbers of fishes (4 males and 4 females). Fishes were implanted with different doses of sustained HCG hormone pellets such as: HCG pellets @ 500 IU/Kg body weight of fish (T1), HCG pellets @ 750 IU/Kg body weight of fish (T2), HCG pellets @ 1000 IU/Kg body weight of fish (T3) and pellets without HCG as control (C). A water depth of 50 cm was kept throughout the experimental period and about 30% of water was exchanged on alternate day. After 5 weeks of hormonal implantation, sample was taken for the estimation of reproductive hormones (estradiol and testosterone), gonadal development (egg diameter, gonadosomatic index (GSI)). Breeding performances (eggs output, fertilization rate and hatching rate) were also estimated for all the groups. The estradiol level, testosterone level, ova diameter, GSI, eggs output and hatching rates were significantly high (p<0.05) in treated group in comparision to control group. T2 showed highest testosterone level (84.76 ± 2.37 pg/ml), GSI (3.94 ± 0.180%), fertilization rate ((95.0 ± 2.0%) and hatching rate (91 ± 2.5%). The results of the present study indicated that HCG @ 750 IU/Kg body weight of fish may be suitable for better maturation and spawning performance of C. striata fish in captivity.
