The research is aimed to reveal opportunity development of the capture fisheries in Talaud Islands Regency by using bionomy approach with Gordon-Schaefer model (Fauzy, 2005) con-cerning the dominant of illegal fishing activities around the area. The research was started by co-llected some secondary data on fish production and number of fishing units. Primary data were collected on catch composition and types of fishing gear. Gordon-Schaefer methods was applied to evaluate the tuna and skipjack resources in the area. The troll and pole and line are indicated as the dominant fishing gears used to catch the skipjack and tuna. In case of open access condition, the production will end up to 25,09 tons, while the resource rent will be end up to zero. For the development, simulations were exercised in 3 scenarios: 1) scenario of enhancing domestic fleet, 2) scenario of illegal fishing, and 3) scenario of net surplus. With those scenarios, if the illegal fishing could be eliminated, the capture fisheries in this regency could render economic value to 10 billion rupiah.

The purpose of this research was to determine the most selective mesh size of gillnet fishing gear for Pampus argenteus in coastal waters of Pangandaran Regency, West Java. Research on the selectivity of gillnet fishing gear was carried out in the coastal waters of Pangandaran, West Java Province, from August 2018 to January 2019. The method used in this research is experimental fishing, namely operating gillnet fishing gear directly in the fishing area with fishermen. The primary data collected was the measurement of the catch (fish weight, number, fork length, how the fish was caught, circumference (girth opercullum, maximum body girth). Meanwhile, the secondary data collected were supporting data from the Pangandaran District Fisheries and Marine Service, and literature study. In determining the sampling, the method used is the purposive sampling method. The operation of gillnets using 4.5 inches obtained a higher proportion of main catch (75%) than gillnets with a mesh size of 5 inches (44%). Gillnet with a mesh size of 4.5 inches, the silver pomfret caught was distributed between 17-22 cm in size with the highest mode in the 19 cm fork length. Unlike the gillnet fishing gear with a mesh size of 5 inches, the silver pomfret caught was distributed in the fork length range of 17-25 cm with the highest mode in the length class 19 cm fork length. mesh size 4.5 inches has a hanging ratio value of 0.51. Meanwhile, the 5 inch mesh size has a hanging ratio value of 0.54. Based on the length distribution, gillnets with a mesh size of 5 inches were more dominant in catching silver pomfret in a larger size class interval than gillnets with a mesh size of 4,5 inches. Based on the L50 value, both selective gillnets caught more fish at 50% second chance. The selectivity curve shows that gillnet fishing gear with a mesh size of 5 inches has more selective results than gillnets with a mesh size of 4.5 inches.

Payang merupakan alat tangkap dengan laju tangkap relatif tinggi di Teluk Jakarta, sedangkan bagan tancap dikenal kurang selektif karena hasil tangkapannya didominasi oleh ikan berukuran kecil baik jenis pelagis maupun demersal. Penelitian ini dilaksanakan dengan metode fishing experiment pada payang dan bagan tancap. Hasil penelitian menunjukkan bahwa hasil tangkapan payang dan bagan tancap didominasi oleh jenis ikan demersal namun proporsi tangkapannya tidak jauh berbeda dengan jenis ikan pelagis. Komposisi ikan hasil tangkapan payang pada Agustus dan Oktober didominasi oleh jenis ikan pelagis, sedangkan pada bulan Desember didominasi oleh jenis ikan demersal. Nilai laju tangkap payang untuk jenis ikan pelagis ditemukan tinggi pada Agustus dan Oktober disebabkan oleh dominasi ikan cekong (Sardinella lemuru) dalam jumlah besar. Komposisi ikan hasil tangkapan bagan tancap pada Mei didominasi oleh jenis ikan demersal, sedangkan pada Oktober didominasi oleh jenis ikan pelagis. Daerah penangkapan payang meliputi perairan Pulau Damar, Pulau Bendera, Muara Pecah, Muara Angke, Pulau Onrust, Pulau Putri, Kronjo, sedangkan daerah penangkapan bagan tancap terkonsentrasi di sebelah barat perairan Teluk Jakarta, sekitar Pulau Kayangan, Pulau Bidadari dan Pulau Onrust.   ABSTRACT Payang, a mini danish seine, is an artisanal fishing gear that has high catchability rate. Like payang, another dominant fishing gear in Jakarta Bay, the lift net, is also known as unselective fishing gear since small fish dominate its catch. This research uses the fishing experiment method with payang and lift net to figure out the gears' catch composition and catch rate. The result shows both fishing gears predominately caught the demersal fish group, but its proportion does not much from the pelagic group. During August and October, the catch composition of payang was dominated by pelagic fish, while demersal fish was caught mostly in December. The high catch rate for pelagic fish was recorded in August and October since cekong fish (Sardinella lemuru) dominated the cath. The catch composition of lift net was dominated by demersal fish during May, while pelagic fish were mostly captured in October. Payang’s fishing ground includes Pulau Damar waters, Pulau Bendera, Muara Pecah, Muara Angke, Pulau Onrust, Pulau Putri, and Kronjo, while the lift net dominates the western part of part of Jakarta Bay including Pulau Kayangan, Pulau Bidadari, and Pulau Onrust.

Abstract The purse seine is the dominant fishing gear operating at the Tumumpa Fishing Port with a vessel of >90%. The purse seines that have developed are large pelagic targets, with the main catch targets being skipjack, mackerel tuna, and tuna. Tuna, mackerel tuna and skipjack are important commodities for fisheries in Indonesia. This study aims to determine the characteristics of purse seine fishing gear and its catch in the Sulawesi Sea. Data collection was carried out for two years from 2019-2020 at Tumumpa Fishery Port. Indications for the use of fish resources are calculated by comparing the length-at-first-capture (Lc) with the length-at-first-mature (Lm). The results showed that purse seines are very dominant in exploiting large pelagic resources (skipjack, mackerel tuna and tuna) with the proportion reaching 78%, small pelagic (21% scads and 1% other fish). The large pelagic fishing season using the purse seine vessel occurs in May – November, with 2 peak seasons in July and September. While the small pelagic occurs in May – September, with the peak occurring in July. The size when the frigate tuna was first caught was at a fork length of 25.15 cm (Lc) and Lm in a size of 28.52 cm for females and 28.29 cm for males. Meanwhile, the first scads was caught (Lc) at a length of 21.4 cm with the length-at-first-mature (Lm) being 20 cm for the female and 19 cm for the male. Based on this analysis, it was shown that the purse seines is a selective fishing gear for small pelagic fish but not selective for large pelagic fish.

<p>Laut Banda merupakan salah satu daerah penangkapan tuna yang potensial di Indonesia, Jenis alat tangkap yang digunakan terdiri dari pukat cincin, huhate, rawai tuna, pancing ulur dan pancing tonda. Hasil tangkapan tuna di Laut Banda meliputi cakalang, madidihang dan tuna mata besar. Sumberdaya tuna di Laut Banda diduga masih merupakan sub stok sumberdaya tuna di perairan Pasifik Tengah dan Barat. Hasil kajian stok tuna oleh Western and Central Pacific Fisheries Commission (WCPFC) pada 2012 melaporkan bahwa stok cakalang dan madidihang tidak mengalami overfishing dan overfished, sedangkan tuna mata besar telah mengalami overfishing dan overfished. Hasil penelitian Pusat Penelitian Pengelolaan Perikanan dan Konservasi Sumber Daya Ikan (P4KSI) pada 2012 menunjukkan madidihang dan tuna mata besar tertangkap pukat cincin, huhate serta kombinasi pancing ulur permukaan dan pancing tonda pada stadium yuwana, dengan indikasi nilai Lc&lt;Lm. Jumlah yuwana madidihang dan tuna mata besar yang tertangkap pukat cincin masing-masing mencapai sekitar 7,9 ton (26%) dan 1,5 ton (5%) dari rerata total hasil tangkapan sekitar 30,29 ton/kapal/trip. Jumlah yuwana madidihang dan tuna mata besar yang tertangkap huhate sekitar 0,71 ton (15%) dan 0,23 ton (5%) dari rerata total tangkapan sekitar 4,79 ton/kapal /trip. Jumlah yuwana madidihang dan tuna mata besar yang tertangkap pancing ulurpancing tonda sekitar 17% dan 2% dari rerata total tangkapan sebesar 0,31 ton/kapal/trip. Saat ini hasil tangkapan tuna yang berasal dari pukat cincin tidak dikehendaki pasar ekspor, mereka lebih memilih tuna hasil tangkapan huhate ataupun jenis pancing lainnya. Oleh karena itu salah satu kebijakan pengelolaan perikanan tuna di Laut Banda adalah tidak mengembangkan alat tangkap pukat cincin, adapun huhate, pancing ulur-pancing tonda masih tetap dapat dioperasikan.</p><p> </p><p>Banda sea is one of potential tuna fishing grounds among others in Indonesia. Various fishing gear types were operatedin this fishing ground such as pole &amp; line (PL), tuna long line (LL), hand line (HL) and troll line (TR). Skipjack (SKJ), yellowfin tuna (YFT) and bigeye tuna (BET) are main species caught in Banda sea and currently assumed as one stock in the Western Central Pacific Ocean (WCPO). Recent stock assessment done by WCPFC in 2012 reported that BET is in overfishing state (F&gt;Fmsy) while YFT and SKJ are not in overfishing or overfished state. It was also reported by RCFMC that the size of catch of those species by various fishing gear indicating that value of Lc&lt;Lm or in other word that catches are in juvenile stage. The juvenile YFT and BET caught by purse seine were considerably high for 7.9 t (26 %) and 1.5 t (5%) of the total catch 30.29 ton/vessel/trip. YFT and BET caught by pole and line are only 0.71 t (15%) and 0.23 t (5%) of the total catch 4.79 ton/vessel/trip. YFT and BET caught by hand line and troll line were only 17% and 2% of total catch 0.31 ton/vessel/trip. Considering the high pressure of purse seine to juvenile of tuna resource and market preference, so that to the best fishing practice for resource sustainability it is suggestted for tuna management in Banda sea should be not to develop and increase the effort for purse seine and may shift to pole line, hand line and/or troll line are still openated.</p>

Catch rate, CPUE, biomass ratios and size selectivity from traditional longline and trammel nets of Turkish coastal small-scale fisheries were investigated in order to describe the Smooth-hound shark (Mustelus mustelus) fishery. The SELECT method was used to estimate the selectivity parameters of a variety of models for the trammel nets inner panel of 150 and 170 mm mesh sizes. Catch composition and proportion of the species were significantly different in longline and trammel nets. While mean CPUE of longline was 119.2±14.3 kg/1000 hooks, these values for 150 and 170 mm trammel nets were 5.3±1.2 kg/1000 m of net and 12.7±3.9 kg/1000 m of net, respectively. Biomass ratios of the by catch to Smooth-hound catch were found to be 1:0.32 for 150 mm trammel net, 1:0.65 for longline and 1:0.73 for 170 mm trammel net. The estimated modal lengths and spreads were found to be 91.1 and 16.2 cm for 150 mm and 103.2 and 18.4 cm for 170 mm, respectively. The modal lengths of the species as well as the spread values increased with mesh size.
