Seasonal changes in the body and liver composition (water, lipid and nonlipids), liver weight and LSI (liver smatic-index) were studied fora period of 14 months in an air breathing fish, Channa striatus (Bloch). The lipid content was maximum (10.68%) in November and minimum (5.20%) in May. The variations in the water and lipid of body and liver showed almost identical trend. The water and lipid contents are inversely proportional to each other. The gonadal cycle and fattening of this fish also seem to be inversely related. The lipid and nonlipid contents were higher in males as compared to females but the water content in females was higher than the males. The LSI is males were higherthan the females.
