SELEKSI KOMODITAS DAN TEKNOLOGI PENANGKAPAN IKAN UNGGULAN DI KABUPATEN KEPULAUAN ANAMBAS (The Superior Commodity and Fishing Technology Selection in Anambas Island Regency)
Abstract
ABSTRACT
Rumpon or Fish Aggregating Devices (FADs) had been used by purse seine and handline fishermen in Pacitan Regency since 2005. The use of rumpon has been associated with the catching of immature fishes in large number that would disrupt the sustainability of fish resources. The aims of this study were to measure fishing productivity of purse seine and handline fleets operated around FADs deployed in eastern Indian Ocean waters and analyze the size distribution and gonad maturity index of the catch. This study was conducted at Tamperan Fishing Port of the Pacitan Regency, East Java Province. Daily fish landing data from both fishing fleets were collected from the Tamperan auction hall from January to December 2014 for productivity calculation. About 289 fish samples from 6 dominant species was taken randomly on-board of 3 purse seine and 2 handlines vessels from 8 different FADs for size distribution and gonad analysis. The average productivity of purse seine fleets in 2014were 6,7 tonnes/trip (s = 5 tonnes/trip) while handling fleets average productivity were 0,9 tons/trip (s = 0,6 tons/trip. Purse seine catch were dominated by immature and juvenile fish while handlines catch were larger and already mature fishes.
Keywords:FADs, fishing productivity, gonad analysis
ABSTRAK
Rumpon atau Fish Aggregating Devices (FADs) telah digunakan oleh nelayan pukat cincin dan pancing ulur di Kabupaten Pacitan sejak tahun 2005. Penggunaan rumpon seringkali dihubungkan dengan penangkapan ikan yang belum dewasa dalam jumlah yang terlalu banyak sehingga dapat mengganggu keberlanjutan sumber daya ikan. Penelitian ini bertujuan untuk menghitung produktivitas alat tangkap pukat cincin dan pancing ulur yang dioperasikan dengan menggunakan alat bantu rumpon yang dipasang di Samudera Hindia bagian timur dan menganalisis ukuran dan tingkat kematangan gonad hasil tangkapannya. Penelitian ini dilaksanakan di Pelabuhan Perikanan Tamperan, Kabupaten Pacitan, Propinsi Jawa Timur. Data pendaratan ikan harian selama bulan Januari hingga Desember 2014 diperoleh dari unit pelaksana teknis tempat pelelangan ikan Tamperan untuk perhitungan produktivitas. Adapun sampel ikan sebanyak 289 ekor diambil dari 3 unit kapal pukat cincin dan 2 unit kapal pancing ulur yang beroperasi di 8 rumpon yang berbeda untuk analisis sebaran ukuran dan tingkat kematangan gonad ikan hasil tangkapan. Produktivitas rata-rata pada tahun 2014 untuk alat tangkap pukat cincin yaitu sebesar 6,7 ton/trip (s = 5 ton/trip), sedangkan pancing ulur yaitu sebesar 0,9 ton/trip (s = 0,6 ton/trip). Hasil tangkapan pukat cincin didominasi oleh ikan berukuran kecil dan belum dewasa, sedangkan pancing ulur menangkap ikan yang berukuran lebih besar dan telah dewasa.
