Assessment of grouper’s catch, diversity and abundance in Saleh Bay, West Nusa Tenggara, Indonesia

Abstract Grouper are demersal fishes that can be found in tropical and subtropical waters. In Indonesia, one of the areas where grouper production takes place Saleh Bay, a semi-enclosed water with small islands, coral reefs high diversity. Information’s about population abundance species Bay currently limited. The benefits this research to enhance availability information on diversity area as fishing ground for future improvement fisheries management Bay. Therefore, study aimed analyse diversity, equitability, richness dominance index different area. data were obtained from field observations fish landing data. caught have been calculated each gear based following parameters: (Shannon-Wiener), richness, index. results showed grounds spread over Fishers around islands reefs. ranged moderate category. We bottom longline highest compare other gears. no using examined gear, or it said evenly calculation equitability
