“…Carvalho et al (2011) menjelaskan bahwa perikanan skala kecilmemiliki potensi besar untuk mencip-takan kelebihan kapasitas dan eksploi-tasi berlebihan terhadap sumber daya pesisir karena ukuran kapal yang kecil telah membatasi kegiatan mereka hanya di daerah penangkapan yang terbatas.…”

Unit fishing and operation in Pacitan very varied, these variations complicated the management of fisheries. Understanding on fishing unit dynamic and characteritic is very important in fisheries management ABSTRAKUnit penangkapan ikan dan pengoperasiannya di Pacitan sangat beragam. Keragamannya menyulitkan pengelolaan perikanan. Memahami dinamika dan karakteristik unit penangkapan ikan, dan pengoperasiannya diperlukan untuk keberhasilan pengelolaan perikanan. Penelitian ini bertujuan untuk menganalisis karakteristik kapal atau perahu penangkap ikan, alat penangkap ikan, nelayan, daerah penangkapan ikan, dinamika pengoperasian alat penangkap ikan, dan menentukan pengelompokkan unit penangkapan ikan.Penelitian ini dilakukan pada bulan Februari, April dan Mei 2013 di Pacitan Kabupaten, Provinsi Jawa Timur. Pengumpulan data dilakukan dengan wawancara pribadi dan observasi. Data dianalisis secara deskriptif dengan tabel, grafik, gambar, dan analisis cluster. Hasil penelitian menunjukkan bahwa kegiatan penangkapan ikan tersebar di sepanjang pesisir Pacitan. Alat penangkap ikan yang dioperasikan adalah kapal motor, perahu motor tempel, dan perahu tanpa mesin. Perahu motor tempel mencapai 84 persen dari populasi perahu di Pacitan. Di sisi lain, alat penangkap ikan yang beroperasi di Pacitan adalah perangkap, pancing, jaring insang, pukat tarik, purse seine, dan jaring angkat. Menggunakan empat parameter (panjang kapal, tenaga mesin, kru, dan alat penangkap ikan) diperoleh setidaknya 6 pola jenis operasi penangkapan ikan. Variasi pola penangkapan ikan disebabkan oleh kemampuan modal dan keterampilan nelayan. Penelitian ini menyimpulkan bahwa unit penangkapan ikan di Pacitan bervariasi dan didominasi oleh perahu motor tempel yang memiliki 6 pola operasi penangkapan ikan.Kata kunci: Dinamika, karakteristik, unit penangkapan ikan, Pacitan

“…International and regional legislation also regulate the use of fishing nets in the area (European Council, 2005), banning the use of bottom and pelagic trawls within an area roughly coinciding with the EEZ (European Council, 1995). The local fishery is typically artisanal and essentially composed of small (<15 m) vessels using hooks and lines (longlines, handlines, pole-and-line; Pinho and Menezes, 2009;Carvalho et al, 2011;Morato, 2012). Gillnets and traps are limited to inshore coastal fishes and crustaceans.…”

Review of the Diversity, Ecology, and Conservation of Elasmobranchs in the Azores Region, Mid-North Atlantic

A vulnerable species group, such as, the elasmobranchs, in a data-deficient context presents a complicated management problem. Evidence suggests that the Azores islands, a remote archipelago on the Mid-Atlantic Ridge, serve essential functions in the life-history of species across taxa. The diversity of marine resources within its EEZ are exploited by local to international fleets, and the full extent of fishing pressure can often be underestimated. Although sharks and rays appear to be of minor importance in the fishery, the possibilities of illegal, unreported, and unregulated fishing raises concerns about these threatened species. However, this group has failed to attract management attention, visible in the lack of regional studies focused on biodiversity, ecology, or threats of elasmobranchs. Our work attempts to review and update the information on elasmobranchs of the Azores and identify potential threats, mainly by the local fisheries. We aim to highlight knowledge gaps that require further research and conservation actions. We (1) update the annotated checklist of elasmobranch species, (2) compare species distribution across a biogeographically similar section of the North Atlantic, and (3) analyze the interaction of elasmobranch species with local fisheries. We confirm 61 chondrichthyan species for the Azores (39 sharks, 17 rays, and 5 chimaeras), adding 19 species to the previous annotated checklist of 1997. The Azores elasmobranch species assemblage most resembles Madeira, the neighboring Macaronesian archipelago. Biogeographic affinities between the chosen regions of the North Atlantic are reflected in the taxonomic structure of families. Although underestimated in the local fisheries, elasmobranchs constitute a regular but highly variable portion of total landings. Misreporting and misidentification is perhaps the greatest concern in the local fisheries records, further aggravated by few existing catch regulations for elasmobranchs. Local knowledge indicates that the Azores serves as essential habitat for at least a few species in coastal areas and shallow seamounts, and potentially so for a number of deep-sea elasmobranchs. The intersection of fishery threats and local essential habitat functions around the archipelago warrants greater research effort and studies.

“…In short, in fisheries, the advance of the free market incentivized and gave rise to capital intensive and efficient practices through a push for technological advancements and industrial mode fisheries (Jacquet, 2009). This resulted predominantly in national strategies focusing almost exclusively on large-scale fisheries and a need for an increase in fishing effort and capacity (Carvalho et al, 2011). The end-result has in some countries been the establishment of de facto private ownership over future fishing opportunities and the establishment of markets where individual transferable fishing quotas (so-called ITQs) (e.g.…”
