Effect of different diets on reproductive performance of skunk clownfish, Amphiprion akallopisos (Bleeker 1853) and water policy from Andaman & Nicobar Islands.

Abstract

The skunk clownfish, Amphiprion akallopisos was studied to access the effect of different wet feeds on reproductive performance such as no. of eggs, spawning frequency, fertilization rate, and hatchability etc. for the first time from Andaman & Nicobar Islands. The wet feeds such as cuttlefish meat, squid meat, fish meat, and prawn meat as control were used. The result from the present study showed that the number of eggs was significantly influenced by the given feed. The fishes served with cuttlefish meat provided the maximum number of eggs (448 ± 5.88) whereas, others are given fewer numbers in comparison with cuttlefish meat. However, fertilization and hatchability were not affected by the tested diets. There was no significant difference in egg length and tasted diets as the capsule had maximum width 1mm in cuttlefish fed group, whereas the highest larval length was observed with squid meat-fed group. It is revealed that the maximum number of spawning was observed in the brooder fishes fed cuttlefish and showed higher reproductive efficiency than others. Hence results from the present study will be helpful for researchers to work on deeper aspects of broodstock nutrition, entrepreneurs, and hobbyists for captive spawning. The law and policy for conservation and management of corals such as tourism, mining, as well as over fishing have been studied for the sustainable production of this species for the marine ornamental fish trade.
