Keanekaramagaman Ikan Hasil Tangkapan yang Didaratkan di PPI Batu Belubang Kabupaten Bangka Tengah

Abstrak

The waters of Bangka Belitung are abundant in fisheries resources, supporting capture fisheries as a driver of the local economy. One of the key fish landing sites is the Batu Belubang Fish Landing Base (PPI) in Bangka Tengah Regency. This study aims to examine the diversity of fish catches in the region as a basis for sustainable fisheries resource management. Catch data from 2023 were analyzed to identify production trends, catch composition, and diversity levels using the Shannon-Wiener Index. The results show that the highest production occurred in October (256,246 kg), dominated by anchovies (56.01%) and squid (16.19%). The production value reached IDR 11.29 billion, with the highest values recorded in May (IDR 1.98 billion) and October (IDR 1.73 billion). The catch diversity index (H’=1.31) indicates a moderate level of diversity, reflecting a fairly varied abundance of fish species but dominated by certain species. This diversity serves as an indicator of ecosystem health and fisheries resource status. The findings can be utilized in species diversity-based resource management to prevent overexploitation and maintain ecosystem balance. Furthermore, diversifying high-value commodities, such as squid, has the potential to improve fishermen's welfare and sustainably increase regional income.
