Abstract Poso in Sulawesi, primarily the Lake Poso and Poso River, is known as eel (Anguilla spp.) fishing areas. Therefore, research of eel fishing is required as base information for evaluating and determining policies for its activities. The eel fishing research in the Poso area was conducted through primary data observations, secondary data traces, and interviews from April to June 2021. The fishing activities take place in the Lake Poso and Poso River shore and the rivers of the lake inlets. The fishing gear that contributed greatly to the catch was fence traps and spears. The local community’s fence trap called waya is a unique gear only found in this area, and it is installed in Poso River around the lake outlets. The gears block the rivers to catch downstream migration eels. The spear is fishing gear (including for eels) operated at night in shallow waters, especially in the outlets of Lake Poso. The eel production recorded from the Poso areas for the last four years has been 6.7–15.5 tons per year, and the highest production was in Pamona Puselemba.

Artisanal fishing is an important traditional activity on the coast of Espírito Santo (ES) State, southeastern Brazil. Despite this, there is a lack of updated data on artisanal fishing and its interfaces with socioenvironmental oceanography. The present study describes the social profile of fishers (gender, age, education, and period of professional activity) and the fishing activity (fishing gear and target species) along the coast of Espírito Santo State. Interviews with semi-structured questionnaires were carried out with 366 artisanal fishers living in 10 fishing communities. The interviewed fishers are mostly male, with low education, who had been fishing for more than 41 years (32%). The fishers described 59 target ethnospecies, with eight being common in 90% (n = 9) of the communities under study. These workers use the following fishing gear: line, longline, gillnet, trawl net, and harpoon. Socioenvironmental oceanography enables obtaining basic information on artisanal fishing, which can support the development of public policies for the sector with a view to maintaining this activity in Espírito Santo State.

Destructive fishing activities are fishing activities using materials, tools or means that damage fish resources and their environment, such as using explosives, toxic materials, strum, and other fishing gear that are not environmentally friendly (Marine and Fisheries Ministerial Decree Number 114, 2019). This activity still occurs in Maluku waters, including in Sawai Bay. The study aims to identify destructive forms of fishing in the waters of Sawai Bay and provide control recommendations to reduce the destructive fishing activity. The study was conducted in January-June 2020 in Sawai Bay. Data collection uses the purposive interview method, while the data is analyzed descriptively. The results showed that in the waters of Sawai Bay, three destructive fishing activities were identified, namely fishing using bombs/explosives, fishing using toxic materials and coral mining activities. Four control strategies are recommended as an effort to reduce destructive fishing activity in the waters of Sawai Bay in the future.   ABSTRAK Aktivitas perikanan merusak atau Destructive Fishing adalah kegiatan penangkapan ikan dengan menggunakan bahan, alat atau cara yang merusak sumberdaya ikan maupun lingkungannya, seperti menggunakan bahan peledak, bahan beracun, strum, dan alat tangkap lainnya yang tidak ramah lingkungan (KepMen KP Nomor 114, 2019). Aktivitas ini masih terjadi pada perairan Maluku, termasuk di Teluk Sawai. Penelitian ini bertujuan untuk mengidentifikasi bentuk-bentuk penangkapan ikan yang merusak pada perairan Teluk Sawai serta memberikan rekomendasi pengendalian untuk mereduksi aktivitas perikana.

While the use of gear restrictions to regulate fishing activity seldom has the objective of improving economic efficiency, it is capable of achieving that result under some conditions. It can also reduce economic efficiency. This paper explores the way several factors affect the sign and magnitude of welfare gains from fishing gear restrictions. These factors include, among others: the fixity or variability of the price of fish and the presence or absence of diminishing short-run average product of effort. Some generalizations are offered regarding the characteristics of fisheries in which gear restrictions are most likely to produce welfare gains.

Abstract Commercial fisheries and oil and gas extraction are both spatially extensive industries in the North Sea (NS), and inevitably there is physical interaction where the two activities coincide. Regular contact between fishing gear and pipelines may risk pipeline integrity and could lead to gear snagging. It is also known, anecdotally, that some vessels target pipelines, potentially benefiting from local artificial reef effects. The impacts of pipeline decommissioning options (removal vs. in situ) on commercial fisheries must be evaluated as part of the consenting process, but the degree of interaction between the two is presently unknown in the NS. Vessel Monitoring System (VMS) data for the Scottish demersal fleet were analysed with spatial data on pipelines. Approximately one-third (36.1%) of trips fished within 200 m of a pipeline over a 5-year period, suggesting that pipelines are subjected to regular interaction with fishing gear. The fishing effort (in hours) associated with pipelines was 2.52% of the total effort, compared to 1.33% in an equivalent area of seabed 1 km away, implying modest aggregation of fishing around pipelines. Only a small percentage (0.93%) of fishing trips actively targeted pipelines as fishing grounds. The highest level of fishing around pipelines occurred in the northeast NS. Pipeline sections with >100 h of fishing were typically larger diameter pipelines. The results suggest that pipeline decommissioning may have both negative (displacement of aggregated effort) and positive (reduced snagging potential) outcomes for commercial fisheries. It is recommended that where there is little or no fishing activity associated with pipelines, receptors other than fishing should be prioritized when selecting decommissioning strategies. Additionally, the intensity of fishing around pipelines should be used to inform the frequency of post-decommissioning integrity monitoring for any pipelines left in situ.

This study aims to determine the productivity of skipjack fish in the waters of Ternate Island. Optimum efforts that produce maximum catch and still maintain stock biomass in equilibrium conditions. Fishing activities are activities carried out to get several catches, to meet demand as a source of food. The demand causes an economic cycle where profits and losses will occur so that fishing activities will be carried out by increasing fish production to achieve maximum profits by fishing businesses. Production and effort data obtained from the Ternate Archipelago Fisheries Port (PPN) and related agencies in the past 5 years (2012-2016) experienced fluctuations. Catches per unit of capture effort (CPUE), reflecting the comparison between the catch and the effort spent. The catch in principle is the output of the fishing activity, while the effort that is needed in principle is input from the fishing activity. CPUE calculations must be standardized for fishing gear first because based on production data there is more than one fishing gear commonly used to catch skipjack fish. It can be seen that in 2013 and 2014 the level of utilization of skipjack fish resources was in the optimal utilization category because the range of skipjack fish production was between 74% to 82%, whereas in 2012 and 2016 the use of skipjack fish in a year was 65% smaller so it was categorized underexploited and in 2015 the level of utilization of skipjack fish resources has experienced overfishing because it has passed the maximum limit that has been set which is 4,252,461.31 tons/year.

Tongkol komo (Euthynnus affinis) merupakan komoditas perikanan ekonomis penting. Di Selat Malaka sumber daya tongkol komo merupakan stok bersama antara Indonesia dan Malaysia yang telah dimanfaatkan secara intensif dengan berbagai alat tangkap. Dalam rangka pengelolaan sumber daya  ikan tongkol komo di Selat Malaka supaya tetap lestari, penelitian ini dilakukan dengan tujuan memperoleh informasi mengenai parameter populasi, aspek biologi dan aspek penangkapan. Penelitian dilakukan secara observasi, enumerasi dan wawancara. Hasil penelitian menunjukkan nilai berbagai parameter populasi; panjang maksimum tercapai (L) = 64,25 cmFL, laju pertumbuhan (K) = 0,96/tahun, laju kematian alami (M) = 1,38 /tahun, laju kematian karena penangkapan (F) = 1,41/tahun, panjang pertama tertangkap (Lc) = 34,5 cmFL dan panjang pertama matang gonad (Lm) = 41,02 cmFL dan laju pengusahaan (E) = 0,50. Dari aspek biologi diperoleh; nisbah kelamin betina : jantan =1 : 1,15, puncak gonad matang dan indek kematangan gonad terjadi pada Maret dan November, mangsa dominan ikan teri (Stolephorus sp.). Alat tangkap utama untuk penangkapan tongkol komo berupa pukat langgai (purse seine). Nilai CPUE tertinggi diperoleh pada Juli dengan musim penangkapan terjadi pada periode April-Juli. Kontribusi tangkapan ikan tongkol komo sebesar 17,42-27,20 % dari total tangkapan ikan. Jenis ikan tangkapan utama yang berinteraksi dengan tongkol komo adalah kembung (Rastrelliger sp.) dan layang (Decapterus sp). Parameter yang bersifat negatif  terhadap kelestarian populasi ikan tongkol komo, seperti ukuran ikan dan hasil tangkapan per unit usaha nilainya kecil. Parameter yang bersifat positif antara lain; rasio antara nilai kematian alami dengan nilai laju pertumbuhan masih dalam kisaran normal dan nilai tingkat pengusahaan masih dalam kisaran optimum. Penangkapan ikan tongkol komo di Selat Malaka masih dalam keadaan normal, tetapi perlu pengawasan terhadap mata jaring dan alat tangkap yang digunakan serta aktifitas penangkapan pada musim pemijahan. Adanya interaksi dengan jenis ikan pelagis kecil dan dominasi ikan teri dalam isi lambung, sehingga dalam pengelolaan ikan tongkol komo harus dilakukan bersama dengan kedua komoditi. Mackerel tuna (Euthynnus affinis) is an important economic fishery commodity. In the Malacca Strait, mackerel tuna  resource is a share stock between Indonesia and Malaysia that has been used intensively with various fishing gear. In order to manage the fish resources of  mackerel tuna  in the Malacca Strait to be sustainable, this research is conducted with the aim of obtaining information on parameteer population, biology aspects and fishing aspects. The research was conducted by observation, enumeration and interview. The results showed the values   of various population parameters: length infinity (L”) = 64.25 cmFL, growth rate (K) = 0.96/year, natural mortality rate (M) = 1.38 /year, capture mortality rate (F) = 1.41 /year, length of first captured (Lc) = 34.5 cmFL and length of first maturity (Lm) = 41.02 cmFL and exploitation rate (E) = 0,50. Biological aspect was obtained; sex ratio female : male = 1: 1.15, peak of mature gonad  and index gonad maturity occurred in March and November, main prey are anchovy (Stolephorus sp.). The main fishing gear for catching mackerel tuna is purse seine. The highest CPUE value was obtained in July with the fishing season occurring in the April-July period. The contribution of catch mackerel tuna are 17.42-27.20 % of the total catch of fish. The main species of fish that interact with mackerel tuna  are mackerel (Rastrelliger sp.) and sardine  (Decapterus sp). Negative parameters to sustainability of mackerel tuna population such as fish size and catch per unit effort are small. Positive parameters are the ratio between the value of natural mortality and the rate of growth is still within the normal range and the level of exploitations rate is still within the optimum range. The fishing of mackerel tuna in the Malacca Strait is still in normal condition, but it is necessary to monitor of the nets mesh size and fishing gear used and fishing activity on spawning season. The existence of interaction with small pelagic fish species and the dominance of anchovy in the contents of the stomach, so that in the management of mackerel tuna fish should be done together with the two commodities.

ABSTRAKNelayan memiliki keterbatasan modal untuk memenuhi kebutuhan investasi dan biaya operasional. Kondisii ini berimplikasi terhadap kelangsungan usaha yang dimiliki. Salah satu strategi yang dilakukan oleh nelayan untuk memenuhi kebutuhan modal adalah dengan cara berhutang. Sumber hutang nelayan didapat dari ‘pengambe’. Tujuan penelitian ini adalah untuk mengkaji permasalahan hutang sebagai pengikat hubungan nelayan dan ‘‘pengambe’.. Penelitian dilakukan pada tahun 2015 di Kabupaten Jember Provinsi Jawa Timur. Data primer dan sekunder digunakan dalam penelitian ini. Pengumpulan data dilakukan melalui wawancara mendalam dan studi literatur. Analisis data dilakukan secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa nelayan membutuhkan ‘pengambe’ untuk menambah kekurangan modal untuk membeli perahu, alat tangkap, dan pemasaran ikan. ‘pengambe’ menjadi penolong, namun ikatan hutang membuat nelayan terikat dan tidak dapat bebas menentukan harga. Rekomendasi yang diberikan adalah perlu diperkuat program pemberdayaan ekonomi dan lembaga permodalan di lokasi sehingga dapat bersinergi dengan ‘pengambe’ . ‘pengambe’ menjadi salah satu aktor yang harus dilibatkan dalam rancangan dan implementasi pengembangan kelembagaan ekonomi masyarakat lokal. Pengalihan wewenang dan dan tanggung jawab ‘pengambe’ kepada lembaga permodalan lokal harus dilakukan secara perlahan dan bertahap sehingga tidak menimbulkan konflik kepentingan. ‘pengambe’  tidak kehilangan mata pencaharian dan nelayan dapat menjadi mandiri mengakses modal seiring dengan peningkatan kemampuannya merencanakan dan mengelola keuangan.Title: Debt As A Binding Relationship Between Fishers And ‘Pengambe’ In The Jember Regency, East Java ProvinceABSTRACTFishers have limited capital to fulfill the need of investment and operational costs of fishing activity. These conditions imply to the sustainability of their business. Debt is one of fishers’ strategy to meet the capital needs, and it is obtained from the ‘‘pengambe’. Purpose of the study was to evaluate debt problems as a binding relationship between fishers and ‘‘pengambe’. Research was conducted in 2015 in Jember Regency, East Java Province. This study used primary and secondary data and they were collected through in-depth interviews and literature studies. Data were analyzed with qualitative descriptive method. The results showed that fishers need ‘pengambe’ to provide them with capital to buy boats, fishing gear and fish marketing. ‘Pengambe’ is a helper for the fishers, but they become strictly bounded and consequently incapable to determine fish prices. This study recommends the necessity to encourage economic empowerment program and local capital institutions to have a mutual relationship with ‘pengambe’.  ‘Pengambe’ should be involved in local economic institution development design and implementation. Authority transfer and responsibility of ‘pengambe’ to the local capital institution should be executed in a gradual step to avoid conflict of interest. Therefore, ‘pengambe’ not lose their livelihoods and fishers able to self-access capital along with ability improved to plan and manage their finance.

Perairan estuaria Sungai Musi merupakan daerah penangkapan ikan yang potensial di Provinsi Sumatera Selatan, sehingga di wilayah ini terjadi aktifitas penangkapan yang cukup padat. Akibatnya terjadi tekanan yang cukup besar terhadap sumberdaya ikan di kawasan ini. Fungsi ekologi estuaria sebagai spawning ground dan nursery ground mulai mengalami gangguan akibat intensitas penangkapan yang besar. Beberapa alat tangkap ikan yang tidak selektif beroperasi dalam jumlah banyak sehingga menyebabkan penurunan terhadap stok ikan. Akibatnya konflik pemanfaatan ruang sering terjadi antar sesama nelayan atau pengguna lainnya. Seperti konflik jaring trawl dengan gillnet dan pancing rawai dan konflik nelayan tuguk dengan pengemudi kapal. Untuk menyelesaikan konflik di atas dan menjaga kelestarian sumberdaya ikan di estuaria Sungai Musi, beberapa langkah pengendalian yang direkomendasikan adalah melakukan pengaturan penangkapan ikan, melakukan sosialisasi peraturan perikanan kepada masyarakat, meningkatkan kapasitas kelembagaan pengelolaan perikanan, pelarangan penggunaan alat tangkap tertentu, dan memberikan bantuan modal usaha kepada nelayan.Estuary of Musi River is a potential fishing areas in South Sumatra Province, so that in this region occur fairly heavy fishing activity. The consequence is a large pressure on fish resources of this region. The ecological functions of estuaries as nursery ground and spawning ground, begin to experience problems due to the large fishing intensity. Some fishing gear that does not selectively operate in large quantities resulted in a decline of fish stocks. As the result spatial use conflicts often occur between fishermen or other user, as examples is the conflict between trawl fishing with gill nets and longline operator and the operator of driver tuguk ship. To resolve the above conflict and preserve the fish resources in the estuary of the River Musi, a few recomendation that must be addressed several step must doing fisheries regulations to disseminate to the public, enhance institutional capacity for fisheries management, ban the use of certain fishing gear and provide venture capital assistance to fishermen.
