Abstract

Perikanan layang yang didaratkan di Pelabuhan Perikanan Nusantara (PPN) Prigi merupakan perikanan pelagis yang disusun oleh tiga spesies sumber daya ikan layang yaitu layang anggur (Decapterus kuroides), layang benggol (Decapterus ruselli) dan layang deles (Decapterus macrosoma). Aturan kendali tangkap pada perikanan layang kerap menggunakan model konvensional spesies tunggal, meski secara teknis tidak sesuai digunakan pada perikanan layang tercampur yang disusun oleh lebih dari satu spesies (multispesies). Aplikasi feedback harvest control rule (HCR) merupakan alternatif aturan kendali tangkap yang tervalidasi yang dapat digunakan untuk perikanan multispesies. Pada penelitian ini dilakukan estimasi jumlah tangkapan yang diperbolehkan (allowable biological catch/ABCy) dengan menggunakan dua aturan kendali tangkap yaitu feedback HCR dan model konvensional surplus produksi Schaefer (1954) dengan menggunakan data hasil tangkapan dan upaya penangkapan (trip) dalam kurun waktu 2011 – 2020. Hasil estimasi model Schaefer (1954) menunjukkan ABCy bahwa hanya dapat diestimasi untuk layang anggur, sementara dua spesies layang lainnya, tidak memenuhi asumsi model Schaefer (1954). Penggunaan aplikasi feedback HCR pada ketiga spesies layang lebih praktis karena mampu mengestimasi ABCy tanpa perlu dilakukan pemisahan data hasil tangkapan dan upaya penangkapan berdasarkan spesies.

Abstract

Small scale fishing is a very important part of the fisheries sector. Not only play an important role in enhancing food security, but also becomes an absorbent for workers without the need for educational. Actors in the small-scale fishery, as defined by Law 45 of 2009, are fishermen who fish their daily needs with the largest size of 5 (five) Gross Register Tonnes (GT) of fishing boats. The fishermen of Prigi are dominated by small fishermen, where the fleet is no larger than 5 GT. The number of small-scale fishing gear in Prigi exceeds 60% of the total gear. The dominance of small-scale fisheries promotes good management with long-term goals, namely the sustainability of fisheries. Today's management of fisheries management has shifted from conventional management to community-based management. In order to support the community-based management of fisheries management, various information about the community, which is the policy objective, is needed. To this end, small-scale fisheries research in Prigi and strategies for the adaptation of the extended fishery fisheries were carried out. The method used is the snowball sampling method and the calculation of the diversity of catching resources. Fishermen who are the subject of the research are small-scale fishermen who operate ships under 5 GT. The gear is stretch fishing, gillnets and tonda fishing rods. There are small fishermen in Prigi who have different types of gear that are used at that time depending on the season of the fish. The selection of fishing gear by fishermen is likely to be caused by different expertise, skills and experience of fishermen in the operation of fishing gears. In addition, the capital held by fishermen to produce fishing gear and the economic level of the fish caught will also likely affect the fishers in choosing the type of fishing gear used each day. The adaptation strategies of fishermen to unpredictable catches are divided into two groups, namely the catch strategy and the search for alternative sources of income.

Abstract

Tawangrejo fishers located in Binangun, Blitar are a group of fishers who conducted destructed fishing. Once fish population decreased, they believed that they must recover the fish population in the Brantas river, especially for a ray-finned fish, Puntius bramoides (Valenciennes, 1842) that live endemic, by forming Community based surveillance named POKMASWAS Fajar Bengawan. The POKMASWAS actively monitor and prohibit destructive fishing, also initiate ecotourism called Badher Bank such as river tracking, fish feeding and fishing. However, Badher Bank still has some constraints related to service management and infrastructure availability. Therefore, the aim of these activities was to increase the service of Badher Bank ecotourism by assisting the group management and building a rest facility for tourists. The results of these activities were the workshop and capacity building for POKMASWAS and the provision of a gazebo. Now, Badher Bank has been well managed with improved management skills and excellent ecotourism services.
