Pukat cincin merupakan alat tangkap utama untuk perikanan pelagis kecil serta mempunyil peranan penting di dalam pengusahaan sumber daya perikanan di Laui iawa Armada pukat cincin berkembang pesat sejak tahun 1976 dan daerah penangkapan tersebar luas di perairan paparan Sunda, di antaranya Laut Jawa, Selat Makassar, Laut Cina Selaian, Selat Karimata, dan saat ini telah mencaoai perairan Sulawesi. Tahun 1994 diindikasikan perkembangan daerah penangkapan ini telah mencapai maksimum. Tujuan dari penelitian ini adalah untuk mengemukakan perkernbangan hasil tangkapan dan upaya ikan pelagis di Laut Jawa berdasarkan pada data berbasis hasil tangkapan pukat cincin yang mendarat di Pekalongan tahun 2002 2007. Hasil perrelitian menunjukkan bahwa ikan layang (DecapterLts spp.) tetap merupakan jenis utama atau dominan hampir di semua daefah penangkapan, yailu 52% dari seluruh hasil tangkapan. Hasil tersebut tidak berbeda ciengan hasil pada tahun 1985-1992. Jumlah trip mengalami penurunan yang cukup signifikan pada bulan Nopember 2005 karena adanya kenaikan harga bahan bakar minyak Penurunan jumlah trip ini diikuti dengan menrngkatnya jumlah hari di laut menjadi sekitar 2 buian. LaJu tangkap ieius mengalaml penurunan dari 1.OOO,7 kg per hari pada tahun 2004, menjadi 409 kg per hari pada tahun 2007. Ratarata laju tangkap tefsebut jauh lebih kecil iika dibandingkan pada tahtrn '1992-1996 yang mencapai 2,387 kg per hari. Di antara 7 daerah penangkapan di perairan Laut Jawa dan Selat Makassar, laju tangkap lebih tinggi dijumpai di perairan sekitar Kepulauan Kangean, yaitu sekilar 950 kg per hari. Purse serne is the main fishing gear of small pelagic fisheries and lhe most impoftant Eeat for flsheries resoufces exploitation in Java sea. since 1976, purse selre has spread out quickly and thc selners were able to extend their exploitation area outsicle the Java sea. ln 1994, it itldicated lhat fishing area has .eached the naxinium point.

This paper summarizes and analyses the landing data collected at Santos, Brazil, during the 12 months period, July 1958-June 1959. These data are given in terms of weight landed of the more important fish and shrimp and also in terms of value. The distribution of the landings of each of the more important species is shown both according to the type of fishing gear used and fishing area. The fishing area is given in the form of statistical rectangles of 60 miles square. The landings are broken down to obtain a figure for the landing per hour of fishing for each species, for each gear and for each rectangle fished. This figure of landing per unit fishing time is used to compare one area with another, one gear with another, and one month with another for each of the important species. In this way, comparisons of the available density of a species by time, area and fishing gear are made.

Peningkatan strategi pengelolaan perikanan pelagis kecil terutama di perairan Laut Jawa tidak hanya dengan menilai stok ikan dan perikanannya, akan tetapi diperlukan juga menilai risiko dampak dari pengelolaan. Dalam tulisan ini disebutkan status estimasi stok dan risiko yang melebihi hasil tangkapan maksimum yang berkelanjutan/Maximum Sustainable Yieald (MSY) terkait dengan nilai referensi terhadap beberapa tingkat tangkapan alternatif yang dihasilkan dari penilaian stok dan risiko penangkapan. Analisis yang digunakan adalah model dinamika biomassa ikan dengan metode non-equilibrium. Data yang digunakan berasal dari PPI Sarang, Rembang yang merupakan basis perikanan pelagis kecil terbesar di Laut Jawa selain Pekalongan. Hasil analisis menunjukkan bahwa nilai MSY yang diperoleh adalah 13.820 ton yang dihasilkan dari upaya penangkapan sekitar 1.759 trip kapal pukat cincin mini. Jika pemanfaatan perikanan sesuai dengan kondisi saat ini, maka estimasi nilai risiko akan berada pada tingkat risiko tinggi, begitu juga jika tingkat pemanfaatan berada pada nilai MSY nya. Nilai risiko akan turun menjadi sedang-tinggi jika pemanfaatan dikurangi 10% - 20% dari kondisi saat ini. Jika tingkat pemanfaatan dikurangi 30% atau lebih, maka nilai risiko dalam 10 tahun berikutnya akan berada pada kondisi sedang-rendah.Improving the management strategy of small pelagic fisheries, especially in the waters of the Java Sea, not only by assessing fish stocks and fisheries, but also needs to determine the risk of management impacts. In this paper, it is stated that the status of stock and risk estimation that exceeds the Maximum Sustainable Yield (MSY) is related to the reference value in several alternative catch levels resulting from stock and risk assessment. The analysis used is a fish biomass dynamics model with a non-equilibrium method. The data used was from TPI Sarang in Rembang, which is one of the largest small pelagic fisheries bases in the Java Sea. Results show that the MSY value obtained is 13,820 tons resulting from the capture effort of approximately 1,759 mini purse seine trips. Suppose the fishery utilization is in accordance with the current conditions, in that case, the estimated risk value will be at a high-risk level, and also if the utilization level is at the MSY value. The risk value will decrease to moderate-high if utilization is reduced by 10% - 20% from the current condition. If the utilization level is reduced by 30% or more, the next ten-year risk value will be in the medium-low condition.

The utilization of fish resources by fishermen in the waters of Bone Bay uses different fishing gear and patterns as well as different utilization and management policies. This can affect the sustainability of existing fish resources, one of which is in the Bone Regency area. This study aims to analyze the technical aspects of purse seine and fishing gear used by fishermen in the waters of Bone Bay, especially in Bone Regency. Furthermore, the technical aspects of the vessel and fishing gear as a result of the calculation are compared with the provisions stipulated in the PERMEN-KP Number 71 of 2016 to determine the zone of the fishing area. This research was conducted in Panyula Village, which is the fishing base area of purse seine fishermen and the waters of Teluk Bone, starting from November 2016 to March 2017. This research uses a combination of survey methods and case studies. The type of data used consists of primary data and secondary data. Based on the technical aspects of purse seine vessels, ring trawl fishing gear and FAD fishing tools, purse seine units should be operated on Fishing Route II and Fishing Route III in accordance with Minister of Marine Affairs and Fisheries Regulation Number 71 of 2016.

The purpose of this study was to determine the yield and type of catch, the comparison of the number of catches and the efforts to manage electronic FADs on Gill Net fishing gear. This research was conducted in Bulukumba waters from February to March 2017. Data collection was carried out by direct observation of fishermen in Bulukumba waters. The samples used in this study were FADs installed by fishermen in the waters of Bulukumba as many as 20 locations. Based on the research results, fish catches with electronic FADs ranged from 98 to 131 fish per fishing trip with a total catch of 2,324 fish. Meanwhile, the usual FAD catches ranged from 51 to 84 fish per fishing trip with a total catch of 1,313 fish and the highest type of fish was selar, followed by male mackerel, Selar bentong, white Kuwe, Layang, Barracuda, selangat and Mata goyang. The ratio between the catch and the use of electronic FADs was 64%, while the regular FADs were 36%. Considering that FADs are an effective tool in collecting fish, a sustainable management strategy is needed, including by (1) community based management, (2) limiting fishing efforts, (3) stopping the addition of shallow marine FADs. , (4) use of fishing gear with large mesh sizes and (5) prioritize the use of deep sea FADs.

SynopsisThe Moray Firth has been intensively fished for many years and has been of great historic importance to the development of Scottish fisheries. The stocks of exploited species in the firth and their relations to other stocks in Scottish waters are described.Exploited demersal species include haddock, cod, whiting, plaice and lemon sole. The firth is an important nursery area for plaice, and is the most important plaice spawning ground in the North Sea.The Moray Firth is also an important nursery area for herring. Evidence suggests that these fish recruit to adult stocks in the Minch. In the early 1960s a pair trawl fishery for sprats started and the firth became the most important sprat fishing area in Scotland. However, recruitment of recent year classes has been too poor to sustain the fishery, which has now been closed in order to protect the juvenile heiring which were landed as by-catch.The distributions of shellfish species are closely related to the bottom sediments. Landings have become increasingly important as the demersal and pelagic fisheries have declined or moved further offshore. The fishery on the Norway lobster is now of particular importance and the catch per unit effort data do not suggest any decline in stock size. Other exploited species include squid, scallops, crabs and lobster.

To obtain data and information of fish trawl fishery performance operated in the Indian Ocean, a research was carried out through observation on board by observers as well as port sampling inSibolga Fishing Port by enumerators in September 2007, with the aimed to study the performance fish trawl fishery. These include fleet structure, trawl net design and construction, catch, fishing trip, fishing ground, and fishing operation. Results of research showed that there were 71 registered fish trawlers in Sibolga Fishing Port and only 25 boats active due to increasing of fuel price. The fleet structure of fish trawler consist of boat with size 31-114 GT which can be classified into 3 categories i.e. small(<60 GT), medium (60-150 GT), and large fish trawler (>150 GT). Design and construction of fish trawl net indicated that fish trawl net operates in the Indian Ocean was high opening trawl with head and ground rope of 27.8-41.5 m and 29,7-45.8 m, respectively. Fishing trip generally 10-12 days with effective days 7-9 days per trip and the number of net setting was 5-6 times each day. The fishing grounds of fish trawl based in Sibolga were the coastal waters area with maximum depth of 91 m. At least 40 species of fishes and shrimps identified during research and dominant fish species was ponyfish (Leiognathus spp.) threadfin bream (Nemipterus spp.), tall fin goatfish (Upeneus spp.), seacatfish (Arius sp.) as well as yellow striped goatfish (Upeneus vitattus). The average of catch of fish trawler fleet in the year of 2007 was 249.3 kg/haul and that number seems smaller than average of catch/haul previous years. This situation indicates that decreasing of catch per haul of fish trawlers based in Sibolga continues occurring and in other hand price of fuel raises significantly so that big fish trawlers size 150 GT with engine power more than 600 HP are not able to continue their fishing operation.

AbstractShark-like batoids (Order Rhinopristiformes) are normally taken as incidental catch in fisheries targeting other species, one exception is a poorly understood Indonesian tangle net fishery. Market surveys of Muara Angke landing port recorded landed catch for this fishery. Recent catch data from Indonesian Capture Fisheries (2017 – 2018) were also examined to provide contemporary information. During the market surveys, 1,559 elasmobranchs were recorded, comprised of 24 species of batoids and nine species of sharks. The most abundant were pink whiprayPateobatis faiand bottlenose wedgefishRhynchobatus australiae, the latter being the main target species. Catch composition differed between individual tangle net boat landings, likely reflecting different fishing grounds, seasonal variation and potential localised declines in species over time. The fishery is highly selective for larger size classes, but smaller size classes of target species are also caught in high numbers in other Indonesian fisheries such as trawl, small mesh gillnet, and hand- and long-line fisheries. As of July 2018, the tangle net fishery was still operating, but few wedgefish were caught and the main landed catch was stingrays. Evidence of substantial and rapid declines in landings of wedgefish species, raises concerns about the status of shark-like batoids and stingrays in Indonesia.

ABSTRACTSmall-scale fisheries are hard to assess because of the limited availability of data. Therefore, a method requiring easy-to-obtain catch-data is important for the assessment and management of small-scale fisheries. The objectives of this study were to assess the effect of fishing gear selectivity on a length-based metric method proposed by Froese by estimating three indicators using catch-data from Lane Snapper (Lutjanus synagris) collected in Honduras. These indicators are (1) the percentage of mature individuals in the catch, (2) the percentage of fish within the range of estimated optimal lengths to be captured and (3) the percentage of fish larger than the optimal length. These indicators determine the level of overfishing. The indicators were estimated separately for catchdata corresponding to gillnets, and each indicator was estimated with and without selectivity correction. Selectivity and mesh sizes of the fishing gear had a major impact in the estimation of indicators 1 and 2. As for indicator 3, it consistently showed a high level of exploitation. The three estimated indicators suggested that the Lane Snapper fishery in Honduras, is experiencing overfishing. Overall, the method proposed by Froese appears to be promising for the assessment of small-scale fisheries, but it should be used cautiously.

AbstractPelagic fisheries in the area of the eastern part of the Adriatic Sea, more precisely in the Croatian fishing grounds, are one of the most important types of fisheries in Croatia. In this paper, the quantitative and qualitative structure of catches obtained by the „ciplara“ purse seine in the Croatian part of the Adriatic Sea was analysed between 2013 and 2018. According to the data collected, the largest catches by this fishing gear were made in the coastal area, precisely in the fishing zones/sub-zones A/A4, E/E2, F/F2, C/C4 and G/G1. 70% of the catches consisted of targeted species, which indicates that the studied „ciplara“ purse seine is a selective fishing gear. Biological analyses are given for four target species.
