SEBARAN SPASIAL DAERAH PENANGKAPAN LEMURU SERTA INTERAKSINYA DENGAN SPESIES TERANCAM, PUNAH, DAN DILINDUNGI (ETP) DI PERAIRAN SELAT BALI
Abstract
The Bali sardinella (Sardinella lemuru) fishery in the Bali Strait is operated by purse seine and gillnet fleets from PPP Muncar and PPN Pengambengan, and its operations may interact with Endangered, Threatened, and Protected (ETP) species. Spatial information on fishing grounds and interaction locations is needed to support fisheries management and improvement efforts through the Fisheries Improvement Project (FIP). This study aimed to analyze the spatial distribution of lemuru fishing grounds by gear type and fleet origin, and to identify fishing grounds where interactions with ETP species occurred in the Bali Strait. Data were collected from May to August 2025 through interviews and participatory mapping with fishers at both ports, then mapped using ArcGIS and analyzed descriptively. A total of 139 fishing ground points were identified, comprising 110 purse seine and 29 gillnet points. Purse seines covered a wider area, extending to the central and southern parts of the strait and beyond the Bali Strait, whereas gillnets were clustered in coastal waters near their home ports. 55 ETP interaction locations were identified, with the highest number recorded for Muncar purse seines (47.3%), followed by Muncar gillnets (30.9%). Recorded ETP species included Rastrelliger brachysoma, Alopias pelagicus, Mobula mobular, and Rhizoprionodon acutus. Interactions were concentrated in Pangpang Bay, Alas Purwo, the central strait, Pengambengan, and Tabanan to Jimbaran. These five areas could be prioritized for monitoring ETP interactions in the management of the lemuru fishery in the Bali Strait.
