Abstract

Tanjung Luar is the center of shark fisheries in Indonesia because it has more shark catches than any other fish landing places in Indonesia. The aims of this study were to present the catch characteristics and the relative abundance of some sharks landing in Tanjung Luar, Lombok. Data were obtained through the interview with enumerators and from their daily monitoring record on the shark landing at Tanjung Luar, East Lombok during eleven months period from January to November 2015. Data statistics were calculated descriptively and presented as a percentage of relative abundance. The result shows the shark caught in 2015 has fluctuated monthly with the peak of catch occurred on September 2015. Total shark caught were about 237.5 tonnes and average landing per day was 1.4 tonnes. Species composition of overall catch comprised of 28 species which belong to 11 families. Among those species, Silky shark/Carcharhinus falciformis (42.06%), Blue shark/Prionace glauca (10.45%) and Blacktip shark/Carcharhinus limbatus (10.31%) were predominant as indicated having relative abundance more than 10%.

Abstract

Kajian penutupan area dan waktu penangkapan udang telah dilakukan, menyusul pemberlakuan moratorium perizinan usaha perikanan tangkap dan pelarangan pengoperasian trawl di Laut Arafura. Kajian ini diperlukan untuk memberikan perspektif pilihan strategi dalam upaya pemulihan stok, dengan pertimbangan manfaat ekonomi dan keberlanjutan sumberdaya udang di Laut Arafura. Dalam status lebih tangkap yang tinggi, lebih banyak diterapkan strategi penutupan musim pada periode pemijahan dan masa perekrutan untuk melindungi induk dan juvenile udang. Dari data biologi, runut kehidupan, dan pola penangkapan udang, diperoleh dua pilihan strategi, yaitu: penutupan sepanjang tahun area penangkapan di sisi barat laut Arafura yang diketahui sebagai habitat pemijahan udang, atau menghentikan seluruh kegiatan pengoperasian pukat udang dan pukat ikan di Laut Arafura pada musim puncak pemijahan, yaitu periode Februari dan Agustus-September. Keputusan pemilihan kedua strategi tersebut memiliki konsekuensi yang berbeda dari sisi biologi, ekonomi dan sosial. Penutupan musim akan efektif jika disertai tindakan lain seperti kontrol tangkapan dan pembatasan jumlah armada/alat tangkap serta kebijakan teknis lainnya seperti kewajiban penggunaan by-catch reduction device (BRD) pada pukat udang dan ikan, penempatan observer diatas kapal, kewajiban penggunaan peralatan vessel monitoring system (VMS) dan sistem pelaporannya.Assement of seasonal and area closure of fishing has been conducted, following the enactment of moratorium on the capture fisheries business and the prohibition of trawling operations in the Arafura Sea. This work is needed to provide a strategic option perspective in the efforts of rebuilding stock, taking into consideration the economic benefits and sustainability of shrimp resources in the Arafura Sea. In situation ofheavy over-exploited, more seasonal closing strategies are adopted during the spawning period and recruitment periods to protect broodfish and juveniles. Based on biological data including life history and shrimp fishing patterns, two strategic options are obtained, i.e., year-round closing of fishingareas on the western side of Arafura Sea known as shrimp spawning habitat, or stop shrimp and fish trawl fishing activities in all areas of the Arafura Sea duringpeak spawning season, i.e., in February and August-September. Decisions on the selection of these two strategies have different biological, economic and social consequences. Seasonal closure will be effective if accompanied by other measures such as catch control and fleet/fishing gear restrictions and other technical policies such as obligation to install by-catch reduction device (BRD) on shrimp and fish trawls, placement of observer onboard of the vessels, obligation to install the equipment of vessel monitoring system (VMS) and their reporting systems.

Abstract

Perlindungan terhadap tiga jenis hiu martil (Sphyrna lewini, S. mokarran, S. zygaena) dan satu jenis hiu koboi (Carcharhinus longimanus) dilakukan dengan diterbitkannya Peraturan Menteri Kelautan dan Perikanan Nomor 59/PERMEN-KP/2014 jo. PERMEN KP No. 34/PERMEN-KP/2015. Peraturan ini menekankan pada pelarangan terhadap pengeluaran hiu dan produk turunannya dari Wilayah Negara Republik Indonesia. Untuk mengetahui efektivitas implementasi regulasi tentang hiu tersebut dilakukan kajian yang dilakukan di empat tempat pendaratan hiu, yakni di Palabuhanratu (Jawa Barat), Cilacap (Jawa Tengah), di Tanjungluar (Lombok Timur) dan di Kota Kupang (Nusa Tenggara Timur). Pengumpulan data dilakukan melalui penelusuran literatur, enumerator, pengamatan langsung dan wawancara dengan nelayan dan pemangku kepentingan. Analisis dilakukan secara diskriptif kualitatif. Hasil kajian menunjukkan bahwa secara keseluruhan terbitnya regulasi pelarangan perdagangan produk hiu belum dipahami sepenuhnya baik di tingkat nelayan, pedagang produk hiu maupun aparat penegak hukum. Hasil kajian merekomendasikan hal sebagai berikut: (1) Kegiatan sosialisasi pemahaman peraturan kebijakan konservasi sumber daya hiu perlu dilakukan secara intensif dan berkesinambungan; (2) Kebijakan peraturan pelarangan ekspor produk hiu (PERMEN KP No.34/PERMEN-KP/2015) perlu segera diperpanjang kembali minimal untuk satu tahun kedepan, berdasarkan pertimbangan karakteristik biologi hiu dan sistem pendataan terhadap hiu Appendiks II CITES yang belum baik; (3) Penyusunan aturan dan ketentuan lengkap perlu dilakukan oleh Ditjen Teknis mengenai pemisahan produk hiu dan mencatat volume berdasarkan jenis hiu yang ditetapkan masuk Appendiks II CITES yang akan diperdagangkan, dan; (4) Penguatan data hiu Appendiks II CITES terus dilakukan dengan pendataan yang mencakup daerah penangkapan, jumlah hiu yang tertangkap, dan distribusi penjualan hasil tangkapan hiu.Protection of three species of Hammerhead sharks (Sphyrna lewini, S. mokarran, S. zygaena) and one species of Whitetip shark (Carcharhinus longimanus) was carried out with the issuance of Ministerial Regulation No. 34/PERMEN-KP/2004 KP and the extension of Ministerial Regulation No. 59/ PERMEN-KP/2015. The regulations emphasize the prohibition on the release of sharks and derivative products from the Territory of the Republic of Indonesia. To find out the effectiveness of the regulation implementation on sharks, a study was conducted in four shark landing sites: Palabuhanratu (West Java), Cilacap (Central Java), Tanjungluar (East Lombok) and Kupang (East Nusa Tenggara). Data collection is done through literature review, enumerator, direct observation and interview with fishers and stakeholders.The analysis is done in qualitative descriptive. The results of the study indicate that the overall regulation on the ban on trading of shark products, has not been fully understood either at the level of fishermen, shark product traders or law enforcement officers. The results of the study recommend the following: (1) The socialization of understanding of the regulations on the conservation policy of shark resources needs to be carried out intensively and continuously; (2) The regulation on the ban on the export of shark products (Ministerial Regulation No.34 / PERMEN-KP / 2015) needs to be renewed at least for the next year, based on the consideration of shark biological characteristics and poor CITES Appendix II shark data collection system; (3) Preparation of complete rules and provisions needs to be published by relaed Directorate General concerning the separation of shark products and recording the volume based on the species of shark that is set in CITES Appendix II to be traded and; (4) Strengthening shark data record of CITES Appendix II consist of fishing areas, number of sharks, and sales distribution of shark catches.
