Effect of hormonal stimulation on captive broodstock maturation, induced breeding and spawning performance of striped snakehead, Channa striata (Bloch, 1793)

•Striped snakehead, Channa striata is a potential candidate species for diversification of aquaculture in Asia.•Broodstock developed in concrete tanks with sustained hCG implant resulted in increased gonadosomatic index and ova size.•Hormone implanted fishes showed better egg output, fertilization and hatching rate.•Method of broodstock development and captive breeding might help in the mass scale seed production of striped snakehead. In the present study, there was assessment of effects of gonadotropin treatments on broodstock maturation, induced breeding, and spawning outcomes of striped snakehead in captivity. The striped snakehead (n = 128) were equally distributed in four concrete tanks (15 m2) and hormone implants (500 IU human chorionic gonadotropin (hCG)/kg body weight) were inserted intramuscularly and striped snakehead broodstock administered this treatment were confined in two tanks and striped snakehead of a non-implanted group were confined in two tanks. The hormone implanted striped snakehead had a greater (P
