Assesmen Risiko Ekologi (ARE) Perikanan Tuna Pole and Line di Flores dan Tonda di Flores dan Pelabuhanratu
Abstract
Abstrak
Kegiatan perikanan tuna dengan penggunaan alat tangkap pole and line dan tonda berisiko menyebabkan kerentanan (risiko ekologi) yang dapat menganggu keberlanjutan stok tuna. Untuk itu dilakukan penelitian menilai kerentanan menjadi parameter risiko ekologi menggunakan pendekatan analisis productivity dan susceptability analysis (PSA) pada jenis ikan tuna sirip kuning (ukuran baby tuna), tongkol, lemadang, dan cakalang. Pengumpulan data biologi dan ekologi dari alat tangkap pole and line dilakukan di Flores dan pancing tonda di Pelabuhanratu. Selanjutnya, analisis laboratorium dilakukan pada Laboratorium Biologi Perikanan, Departemen Manajemen Sumberdaya Perairan, Fakultas Perikanan dan Ilmu Kelautan IPB. Hasil analisis produktivitas dan susceptabilitas alat pole and line untuk ikan baby tuna 1,42 dan ikan tongkol 1,98. Nilai ini menunjukkan tingkat kerentanan dan risiko ekologi pada ikan tongkol tergolong tinggi dan ikan baby tuna masih rendah. Analisis PSA dari alat pancing tonda pada ikan baby tuna diperoleh sebesar 2,34; ikan lemadang sebesar 2,34; dan ikan cakalang 2,18. Nilai ini menunjukkan bahwa kerentanan tinggi dan risiko ekologi pada ketiga jenis ikan tersebut juga tinggi karena penggunaan pancing tonda. Penggunaan alat tangkap pole and line serta pancing tonda pada perikanan tuna menyebabkan tingginya risiko pada ikan tuna sirip kuning (ukuran baby tuna), lemadang, cakalang, dan tongkol.
Abstract
Tuna fishery activities using pole and line fishing gear and tonda have the risk of causing vulnerability (ecological risk) which can disrupt the sustainability of tuna stocks. For this reason, a study was conducted to assess vulnerability which is a parameter of ecological risk using the productivity and susceptibility analysis (PSA) approach to the fish’s species are albacares (baby tuna), mackerel, lemadang, and skipjack. Biological and ecological data collection from pole and line fishing gear was carried out in Flores and trolling and tonda in Pelabuhanratu. Furthermore, laboratory analysis was carried out at the fisheries biology laboratory, Department of Aquatic Resources Management, Faculty of Fisheries and Marine Sciences IPB. The results of productivity and susceptibility analysis of the pole and line for baby tuna and Euthynnus are 1.42 and 1.98. This value shows the level of vulnerability where the ecological risk of tuna is high and baby tuna also low. The PSA analysis of the tonda for baby tuna was 2.34; lemadang was 2.34; and skipjack was 2.18. This value indicates that the high vulnerability and ecological risk of the three species of fish are also high due to the use of tonda. The use of pole and line fishing gear and tonda lines in tuna fisheries causes a high risk for albacares (baby tuna), mackerel, lemadang, and skipjack.
