نویسندگان

چکیده

Terjadinya penurunan produktivitas perikanan tuna di Perairan Selatan Jawa salah satunya disebabkan oleh adanya kondisi tangkap lebih yang terjadi akibat ketidaktersediaannya informasi geografis akurat terkait jumlah dan jenis spesies. Pendekatan spasial keragaman habitat spesies mampu memberikan prediksi tentang pada suatu daerah penangkapan. Penelitian ini bertujuan untuk menghasilkan peta klasterisasi berdasarkan data hasil tangkapan lokasi penangkapan diperoleh dari kapal rawai menangkap ikan Samudera Hindia mendaratkan tangkapannya Pelabuhan Perikanan (PPS) Benoa bulan September-November 2019 dengan menggunakan beberapa analisis yaitu: (1) (Shannon-wiener index Menhinick index) (ward-hierarchical clustering bootstrapped p-value). Berdasarkan kedua tersebut tiga klaster pola sebaran didominasi Thunnus albacares, (2) obessus, (3) berimbang. Informasi mengenai ketiga selanjutnya dapat digunakan sebagai rujukan penentuan pengelolaan upaya pembatasan kapasitas khususnya mengalami stok.
