Abstract:
Snakehead fishes of family Channidae play an important role in fish biodiversity with 32 total species. Channa striatus is an important fish of Channidae family. It is very useful and economic important fish used as food, game, ornamental and pest controller fish in different regions. This is a native of Indian subcontinent, found in India, China, Pakistan, Sri Lanka, Bangladesh, Nepal, Vietnam and Malaysia etc. The culture production and conservation by aquaculture have much important for present scenario because the population of Channa striata fish species decline by several anthropogenic activities due to destruction of their natural habitats and over fishing. The reproductive biology has the important part of Gonado-somatic Index for the aquaculture production. It is direct effect to survival growth breeding mechanism and their technology formation. Present study provides the basic idea for the Gonad-somatic index which express the relative change in gonad weight to the percentage of body weight. Present study indicates the Channa striatus GSI in around Etawah District (Uttar Pradesh) India, during study period from January to June. GSI have increased with gonadal development and maturation of this fish. GSI value was minimum at January during pre spawning period was 0.274 ± 0.014 and maximum at peak maturation period during June 4.32 ± 0.24 in female and in male GSI is 0.138 ± 0.026 minimum and 0.230 ± 0.018 maximum.
