The present study explains the seasonal influence on fecundity, embryonic development and parental care of Amphiprion melanopus reared in aquaria. Water quality parameters like temperature 27 ± 2°C, salinity 29 ± 2ppt, ammonia 0.001 ppm, dissolved oxygen 4 ±2 ppm, pH 7.7 ± 0.2, light intensity 18 μ mol-1sec-1and photoperiod (13 L: 11 D) were provided. Brooders were fed with boiled oyster,shrimp and clam meet thrice a day and organic wastes wereremoved regularly. After obtaining maturation (4 months rearingin captive condition) successful spawning was observed. Thepercentage of fecundity, hatching, deformation and incubation were categorized into four seasons (summer, pre-monsoon, monsoon and post-monsoon) for a year. The spawning was occurred throughout the year except in December. The fertilization, hatchingand deformation rate were calculated as 92.85%, 85.64% and7.18%. There is no significant (P>0.05) changes were observedin fecundity and hatching rate seasonally. However, the incubationhours and deformation rate of egg clutch were significantly (P<0.01)varied based on the seasons. From this study, it is concluded thatthe spawning efficiency of red black anemone fish is not influencedby seasons throughout the year and it is feasible to culture in Indianenvironment.
