Abstract: Bubu merupakan jenis alat tangkap dominan yang dioperasikan di Kepulauan Seribu berjumlah 44.480 unit dengan jumlah kapal 334 kapal. Penelitian ini mengkaji dampak ghost fishing oleh bubu tambun di Kepulauan Seribu. Ghost fishing adalah alat tangkap yang hilang, dibuang atau terbengkalai pada suatu perairan. Nelayan di Kepulauan Seribu sebagian besar menggunakan alat tangkap bubu, sehingga berpontensi terjadinya ghost fishing. Bubu yang dipasang (seakan-akan hilang) diamati selama 6 minggu untuk menentukan jumlah, jenis, bobot tangkapan, perilaku, dan mortalitas ikan, serta nilai ekonominya. Penelitian ini dilakukan dengan metode observasi langsung menggunakan 8 unit bubu tambun pada kedalaman antara 1-2,5 meter selama 6 minggu dan wawancara. Pada 8 unit bubu, rata-rata tangkapan mingguan mencapai 3–13 ekor, total 383 ekor. Keanekaragaman hasil tangkapan sedang (H’=2,81), didominasi ikan pasir (Pentapodus tritatus, 17,49%). Pada minggu ke- 6, hasil tangkapan yang didaratkan sebanyak 65 ekor dengan bobot 6.260 gram, didominasi ikan kakatua hijau (20,93%). Mortalitas terjadi pada ikan pasir (2,9%) dan ikan jarang gigi (20%), dengan kerugian ekonomi Rp 99.480. Kata kunci: bubu, ghost fishing, Kepulauan Seribu, keragaman, tingkah laku ikan, distribusi hasil tangkapan
Bubu is the dominant fishing gear operated in the Seribu Islands, totaling 44,480 units with 334 vessels. This study examines the impact of ghost fishing by bubu tambun in the Seribu Islands. Ghost fishing is a fishing gear that is lost, discarded or abandoned in a waters. Fishermen in the Seribu Islands mostly use bubu fishing gear, so there is the potential for ghost fishing. The installed bubu (as if lost) were observed for 6 weeks to determine the number, type, weight of catch, behavior, and mortality of fish, as well as their economic value. This study was conducted using direct observation methods using 8 bubu tambun units at a depth of between 1-2.5 meters for 6 weeks and interviews. Observation from 8 bubu units, the average weekly catch reached 3-13 fish, with a total of 383 fish. The diversity of the catch was moderate (H'=2.81), dominated by sandfish (Pentapodus tritatus, 17.49%). In the 6th week, the catch landed was 65 fish weighing 6,260 grams, dominated by green parrotfish (20.93%). Mortality occurred in sandfish (2.9%) and toothless fish (20%), with an economic loss of Rp 99,480. Keywords: trap, ghost fishing, Seribu Islands, diversity, fish behavior, catch distribution
