Abstract

Growth and colour quality of hatchery bred clownfish, Amphiprion sebae were monitored in three sets of feeding trials with polychaetes, trash fish and clam meat. The increment in length (4.55±0.17 cm) and weight (5.15±0.57 g) were found to be more in fishes fed on polychaetes followed by fishes fed with trash fish (4.11 ±0.08 cm and 4.95±0.5 g) and clam meat and (4.10 ±0.05 cm and 3.38 ±0.62 g). Enhanced colour quality was also noticed in fishes fed with polychaetes. Fatty acid profile showed a high level of PUFA in polychaetes compared to other two feeds. Two ñ way ANOVA indicated significant variations in length and weight in relation to days of experiment and treatments. The present study shows usefulness of polychaetes in enhancing the growth and colour quality of ornamental clownfish.
