Seasonal Disparity in Fecundity and Embryonic Development of Cinnamon Anemone Fish, Amphiprion melanopus (Bleeker, 1852) In Captivity

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 were removed regularly. After obtaining maturation (4 months rearing in captive condition) successful spawning was observed. The percentage of fecundity, hatching, deformation and incubation were categorized into four seasons (summer, pre-monsoon, monsoon and post-monsoon) for a year.
