Abstract

Sebagai anggota Indian Ocean Tuna Commision (IOTC) Indonesia wajib mengadopsi isi Resolusi IOTC 10/12 yang mengatur pengelolaan sumberdaya ikan hiu thresher (famili Alopiidae). Secara spesifik Indonesia belum melaksanakan pengelolaan sumberdaya hiu thresher karena spesies tersebut belum mendapatkan perhatian serius. Tulisan ini bermaksud menyampaikan hasil penelitian tentang ikan hiu thresher (Famili Alopiidae) yang tertangkap rawai tuna di Samudera Hindia berbasis di Cilacap. Data diperoleh dari kegiatan pengambilan contoh di pelabuhan tahun 2010, kegiatan observasi di atas kapal rawai tuna bulan Januari 2010 dan laporan statistik PPS Cilacap tahun 2006-2010. Hasil kajian menunjukkan bahwa: (a) di perairan Indonesia ada dua spesies dari tiga spesies hiu thresher yang ada di dunia, yaitu hiu monyet atau pelagic thresher (Alopias pelagicus Nakamura 1935) dan hiu paitan atau bigeye thresher (A. superciliosus Lowe 1840). Satu spesies lainnya yang belum pernah ditemukan adalah thinfin thresher (A.vulpinus Bonnaterre1788).  Dilihat dari teknologi rawai tuna yang digunakan, daerah sebaran hiu thresher sama dengan tuna di Samudera Hindia, sehingga sulit untuk menghindari tidak tertangkapnya hiu thresher oleh rawai tuna. Jumlah dari jenis hiu monyet yang tertangkap rawai tuna di Samudera Hindia berkisar 0,1-0,6 % dan hiu paitan berkisar 0,1-1,3 % dari total tangkapan. Ukuran hiu thresher yang tertangkap rawai tuna umumnya ikan yang telah dewasa (berkisar 54-74%) dan diduga telah mengalami pemijahan. Hampir semua bagian hiu thresher dimanfaatkan sebagai bahan pangan dan farmasi. Selain dipasarkan di dalam negeri, ikan hiu thresher juga diekspor terutama siripnya ke manca negara dan terbanyak ke China. As a member of IOTC, Indonesia is obliged to implement all IOTC’s resolutions including resolution 10/12 on the conservation of thresher sharks (Family Alopiidae) caught in association with fisheries in the IOTC area of competence. Indonsia has not implementing the Resolution 10/12 yet, especifically for thresher sharks as an important resource. Therefore, in order to support implementation of the IOTC Resolution 10/12, this paper presents results of a research on thresher shark caught by tuna long line operated in Indian Ocean based at Cilacap was carried out.  Data obtained by port sampling program in Cilacap Fishing Port in 2010, onboard observer program on the commercial tuna long line vessel based in Cilacap on January 2010 and annual report (fisheries statistic) of Cilacap Fishing Port 2006-2010 were used within this paper. The result showed that: (a) thresher sharks are one of bycatch in tuna long line fisheries; (2) there are two species of thresher shark caught by tuna long liner i.e. pelagic thresher (Alopias pelagicus Nakamura 1935) and bigeye thresher (A.superciliosus Lowe 1840), while thinfin or fox thresher (A.vupinus Bonneterre 1788) has not been noted in the catch composition so far.  The percentage of pelagic and bigeye thresher sharks caught by tuna long liner were 0.1-0.6 % and 0.1-1.3 % of the total catch, respectively. Mostly, the thresher shark caught by tuna long line is adult fishes (54-74%) this predicted that this species has spowned.  The products of thresher are marketed locally and exported, mainly to China, especially for their fin.

Abstract

Perairan karang Scott (Scott Reef) yang terletak disekitar Pulau Datu berada di Perairan Laut Timor – Australia khususnya di lokasi MoU Box 74. Banyak nelayan tradisional Indonesia yang berasal dari Pulau Rote Alor dan Madura menangkap teripang di kawasan tersebut sebagai mata pencahariannya secara turun temurun. Suatu penelitian merupakan kerjasama antara Pemerintah Indonesia (Badan Penelitian dan Pengembangan Kelautan dan Perikanan) dan Pemerintah Australia (Australian Fisheries Management Autority) telah dilakukan pada bulan September 2008. Sebagai bagian dari penelitian tersebut, telah dilakukan pengamatan teripang yang mencakup aspek biologi (panjang, berat, identifikasi jenis) dan aspek penangkapan (hasil tangkapan, deskripsi perahu dan alat tangkap). Hasil penelitian teridentifikasi 20 jenis teripang yang ditangkap oleh 29 unit armada tangkap yang berasal dari Pulau Rote Alor dan Madura. Terdapat 5 jenis teripang yang dominan tertangkap dan mempunyai nilai ekonomis tinggi yaitu Holothuria nobilis, Stichopus chloronutus, Bohadschia argus, Bohadschia marmorata dan Bohadschia sp. Peralatan yang digunakan adalah pancing, lampu lentera, kacamata selam, tombak, dan keranjang penampung. Scott Reef or Datu Island waters was located in Timor Sea-Australian side, namely Mou Box 74. Since many years ago fishing activities had been going by Indonesian traditional fisherman from Rote Island Alor and Madura. The main fishing activities was to collect sea cucumber (“trepang”). The research was done a collaboration between The Agency for Marine and Fisheries Research and Development (AMFRD) Ministry of Marine Affairs and Fisheries and Australian Fisheries Management Authority (AFMA) in September 2008. Length and weight measurements, species identification were conducted for biological parameters and ( total catcth, boat description and type fishing gear for fisheries aspects). There were 20 species of sea cucumbers or trepang identified. That caught by 29 units of fishing boats in Datu Island came from Rote Island, Alor and Madura. The dominant species of Holothuria nobilis, Stichopus chloronutus, Bohadschia argus,  Bohadschia marmorata and Bohadschia sp have economically importen sea cucumbers. Fishing equipments, lantern lights, goggles, spears, and basket traps were used for collection of sea cucumbers.
