Potency of reef fishes in Tuhaha bay waters, Central Maluku Regency, Maluku Province, Indonesia

Abstract

The research aimed to provide data on taxa composition, density, standing stock and potency of reef fishes at Tuhaha bay waters in 2017. There were 35 families, 105 genera and 243 species of reef fishes found in Tuhaha bay. Four areas of coral reef at good until excellent categories and various habitat had high species richness of reef fishes. Species richness, density and standing stock of major reef fishes species were higher than target and indicator species. Potency (biomass) of economically food fish (target species) ranged from 1.65 - 5.59 tons ha−1 of coral reef (total 2.93 tons ha−1). Total potency, Maximum Sustainable Yield and Allowable Total Catch of economically food fish in 389,70 ha of Tuhaha bay coral reef area were 1,141.82, 590.91 and 456.73 tons, respectively. The status of reef fishes in two coral reef areas belonged to a high category, while the other nine areas had a moderate category.
