Abstract

Pongok Island possesses small islands surrounded by waters with some primary commodities of sea farming. Seeking appropriate locations for marine aquaculture is a careful planning step to acquire optimal results. The sustainability of sea farming areas should be set based on considering species for easy implementation. This research aimed to analyse the area's suitability for aquaculture activities of seaweed cultivation, rearing groupers, and lobsters in floating net cages, and pearl oyster farming.  This research occurred from June to November 2022 in Pongok Islands, South Bangka Regency, Indonesia. The method used in this research consisted of parameters weighting and scoring for cultivating seaweeds, groupers, or lobsters utilizing floating net cages and pearl oysters.  Sea water samples analysis was processed in the Marine Science Laboratory of Bangka Belitung University and PT Global Quality Analytical, Bogor – West Java.  Collected data were then scaled based on expert justification of scaling priority on aquaculture suitability. The mapping area of sea farming locations based on potential resources was then determined using map software. This research indicates that cultivating seaweeds is recommended to be established in two stations, 1 (149.79 ha) and 2 (186.46 ha), that are very suitable (S1) and the suitable (S2) categories, respectively. Station 3 (325.41 ha) and 4 (4.11 ha) are grouped into very suitable (S1) categories for pearl oysters and groupers or lobsters using floating net cages, respectively. The total estimate for sea farming in the waters of Pongok Island is 665.77 ha. Allocating seawater spaces should be assigned for sustainable fishery management. Maps of area suitability for sea farming can obviate conflicts in seawater areas.

Abstract

Gelasa Island has a coral reef ecosystem as a habitat for biota including coral reef fish, turtles, and others. The coral reef has been damaged due to anthropogenic activities. The purpose of the study was to determine the percentage of coral reef cover and the abundance of coral reef fish. The study was conducted in March 2024 in the waters of Gelasa Island. The method used was UPT (Underwater Photo Transect) for coral reefs and UVC (Underwater Visual Census) for coral reef fish, and the PAST 4.03 application to determine the diversity, uniformity, and dominance index. The results of the study showed that the percentage of coral reef cover in the waters of Gelasa Island was in the good category with an average of 52.42%. The abundance of coral reef fish was 49,114 ind/ha in the very rare category. The highest abundance of coral reef fish species was Neopomacentrus anabatoides, Pomacentrus alexanderae, and Caesio cunning. Based on the category, major fish have the highest abundance. The diversity value is in the moderate category, the uniformity value indicates an unstable community, and the dominance value is in the low category.
