Broodstock nutrition is one of the most important research areas in aquaculture. In this
study, sebae clownfish was used to find out the influence of diet on reproductive performance
parameters like egg production, fertilization rate, hatchability, and larval quality. The feeds used
were of marine origin such as squid, cuttlefish, deep sea prawn, immature and mature mussel.
The diets were analyzed for their proximate composition, amino acids profile, fatty acids profile
and astaxanthin. The sub-adult fishes were collected from wild and conditioned prior to
experiment. Data were collected after initial three spawning to achieve stability in egg production
and quality. The egg production was found to be significantly influenced by diet and those fed
cuttlefish meat gave the highest number of eggs per clutch (1520±260 eggs). The fertilization
rate and hatchability were found to be unaffected by the tested diets. The highest larval survival
(62.3±7%) after 12 days post hatching was obtained for fish groups fed deep sea prawn. The
dietary carotenoid content was also found to influence the egg and larval pigmentation. The
result also indicates the importance of dispensable amino acids in egg production. The role of
protein, lipids, and essential fatty acids in the broodstock diets for sebae clownfish are also
discussed.
