Grouper is an important economic commodity whose existence continues to be sought after by fishermen. Knowing the types of fish landed and marketed at TPI Lewoleba will be very helpful as a basis for sustainable fisheries management that is appropriate for improving the quality of fish on the market, starting from the fishing management process, handling fishery products, processing, marketing and so on, so that it can also improve the welfare of the fishing community. This research was carried out at TPI Lewoleba in September 2024 – December 2024. The aim of this research was to determine the type of grouper (Serranidae) caught by fishermen landed at the TPI Lewoleba market. The method used in this research is descriptive research method. The results of the research are the types of grouper fish (Serranidae) landed at the TPI Lewoleba market, namely the species Cephalopholis boenak, Variola louti, Epinephelus ongus, Epinephelus fasciatus, and Cephalopholis miniata, Plectropomus leopardus, Epinephelus coeruleopunctatus, and Anyperodon leucogrammicus, Plectropomus oligacanthus, Plectropomus areolatus, and Epinephelus macrospilos, Cephalopholis sonnerati and Epinephelus undulosus. Based on the identification results of grouper fish (Serranidae) landed at the Lewoleba Fish Auction Place (TPI), 13 species were recorded.

Abstract

Lembata Regency marine waters have a high level of biota diversity. The purpose of the study was to determine the species composition and diversity index of grouper (Serranidae). Data analysis was carried out by calculating the index value of species diversity, species evenness and species dominance. The results showed that the species composition landed at Lewoleba Fish Auction Site (TPI) was dominated by Cephalopholis boenak species at 10%, followed by Variola louti, Epinephelus ongus, Epinephelus fasciatus, and Cephalopholis miniata at 9%, then followed by Plectropomus leopardus, Epinephelus coeruleopunctatus, and Anyperodun leucogrammicus at 8%, followed by Plectropomus oligacanthus, Plectropomus areolatus, and Epinephelus macrospilos at 7%, followed by Cephalopholis sonnerati at 6%, and the last was Epinephelus undulosus at 3%. The diversity index (H') varied from 2.452 to 2.548. Based on the index value, the diversity index category is moderate (1 < H' < 3). The diversity index (E) varied from 0.956 to 0.993. Based on the index value, the evenness index category is high or evenly distributed. The dominance index (E) varies from 0.080 to 0.093. Based on the index value, the dominance index category is low or almost no dominance.
