Purse seine is considered to be the most productive fising gear to catch pelagic fish, so there are many purse seiners that based in Bitung Oceanic Fishing Port operate in Fisheries Management Area of the Republic of Indonesia (WPP) 715 Moluccas Sea. There was and  issue that the catches of purse seiner around FADs was classified as immature fish. Therefore,  necessary to study the diversity and distribution of purse seiner catches in the area.  The data collection was done by direct observation and active participation in the field and deep interviews with the crews of Grasia 04 purse seiner. At each hauling, twenty fish from each species were taken randomly measured their fork lengths.  Catches during the study consisted of six species; namely skipjack (Katsuwonus pelamis), yellow fin tuna (Thunnus albacores), little tuna (Auxis thazard), scad mackerel (Decapteru smacarellus), rainbow runner (Elagatis bipinnulata), oceanic trigger fish (Canthidermis maculata) and trevally (Selaroides leptolepis). The dominatcatch in each hauling were skipjack, yellowfin, tuna and scad mackerel. Results were showed that most of the catches of Grasia 04 purse seinerin the waters of Moluccas Sea not legal size.Keywords: Composition and distribution catch, purse seiner Grasia 04, Molucca Sea. ABSTRAKAlat tangkap purse seine dianggap paling produktif untuk menangkap ikan pelagis, sehingga banyak kapal purse seine yang berpangkalan di  Pelabuhan Perikanan Samudera Bitung beroperasi di Wilayah Pengelolaan Perikanan RI (WPP) 715 Laut Maluku. Beberapa issue menyebutkan bahwa hasil tangkapan purse seine terutama di sekitar rumpon tergolong ikan-ikan yang belum dewasa. Oleh karena itu, perlu mempelajari keragaman dan distribusi hasil tangkapan purse seine di wilaya tersebut.  Pengumpulam data dilakukan dengan cara pengamatan langsung dan partisifasi aktif dilapangan, wawancara dengan anak buah kapal KM Grasia 04.

This study examines the fishing productivity of handling with operated by a fisherman in Majene district, West Sulawesi. Fishing activity utilizing FADs as a fishing ground. Fishing Productivity was obtained from the weight ratio of the amount of catches and duration of fishing time. Fishing productivity is determined for each type of fish catches, namely skipjack tuna (Katsuwonus Pelamis), yellowfin tuna (Thunnus albacares), and mackerel tuna (Auxis thazard). The proportion of the total catches of skipjack tuna showed greater than other fish species. The relationship between fishing productivity with the time fishing is declining with increasing duration of time fishing. Cluster analysis showed that there are two clusters of fishing productivity for 23 fishing activity. Fishing ground with the largest production was in the FADs in 118031'44,8''E and 118°34'16.0"E, and 04030'25.6"S and 118029'37,3''BT. Large pelagic fish species observed is the skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), and tongkol (Auxis hazard). Fishing productivity shows the downward trend and the fishing ground for the production of tuna, mackerel and yellowfin tuna fish highest in FADs at position 04026’06,3”S and 118031’44,8’’E ; 04030’25.6”S and 118029’37,3’’E.<br /><br />Keywords: FADs, fishing productivity, handline, large pelagic, majene<br /><br />ABSTRAK<br /><br />Ikan pelagis besar merupakan salah satu komoditi perikanan yang memiliki nilai ekonomi yang relatif tinggi, sehingga pengembangan perikanan pelagis besar dapat meningkatkan ekonomi masyarakat dan daerah. Tujuan penelitian ini adalah menentukan produktivitas penangkapan ikan pelagis besar menggunakan pancing ulur. Penelitian ini dilakukan pada Bulan Juli-September 2012. Penelitian ini mengkaji produktivitas penangkapan pancing ulur yang dioperasikan nelayan di Kabupaten Majene, Sulawesi Barat. Aktivitas pemancingan memanfaatkan rumpon sebagai daerah penangkapan ikan. Produktivitas penangkapan diperoleh dari perbandingan berat jumlah hasil tangkapan dengan lama waktu pemancingan.

Pukat cincin merupakan salah satu jenis alat penangkapan ikan yang digunakan oleh nelayan di Indonesia untuk menangkap ikan pelagis termasuk tuna dan cakalang. Cakalang dan madidihang/tuna sirip kuning merupakan komoditas perikanan penting di Indonesia untuk kebutuhan pasar domistik dan ekspor. Penelitian ini bertujuan untuk mengetahui karakteristik alat tangkap pukat cincin pelagis besar terutama yang menangkap cakalang dan madidihang di perairan WPPNRI 572 dan 573 (Samudra Hindia). Pengumpulan data dilakukan selama tiga tahun dari 2016-2018 di 18 pelabuhan perikanan yang armadanya melakukan aktivitas penangkapan di perairan WPPNRI 572 dan 573. Indikasi proporsi ikan yang sudah dan belum matang gonad dihitung dengan membandingkan ukuran ikan dengan ukuran pertama kali matang gonad (Lm). Hasil penelitian menunjukkan bahwa alat tangkap pukat cincin sangat dominan dalam mengeksploitasi sumber daya cakalang dan madidihang dengan proporsi mencapai 95% di WPPNRI 572 dan 66% di WPPNRI 573. Kebanyakan ikan yang tertangkap didominasi oleh ikan yang belum matang gonad dengan proporsi sebesar 67% untuk cakalang dan 94% untuk madidihang. Hasil analisis menunjukkan bahwa pukat cincin tidak termasuk alat yang selektif untuk menangkap ikan madidihang. Selanjutnya untuk target ikan cakalang, ukuran mata jaring harus diperbesar untuk mencegah tertangkapnya ikan yang belum matang gonad.Purse seine is one of dominant fishing gear used to catch pelagic species include skipjack and yellowfin tuna, two commercial species in Indonesia’s marine waters. This research aimed to analyze characteristic of purse seine fishery focusing on skipjack and yellowfin tuna within FMA 572 and 573. All the catch-effort data was collected from 18 fishing ports during the period of 2016-2018. All the vessels (purse seiners) were known to be actively fished within FMA 572 and 573. Proportion of mature and immature fish were calculated by comparing the fish length with its length at first maturity (Lm). The results showed that purse seine was a significantly gear to catch skipjack tuna and yellowfin tuna with proportion of 95% in FMA 572, and 66% in FMA 573, respectively. Most of the catch were dominated by immature fish with proportion of 67% for skipjack tuna and 94% for yellowfin tuna. The study concluded that purse seine is not recommended to exploit yellowfin tuna. Futhermore for targeting skipjack tuna, mesh-size of the net need to be in creased, allowing immature fish to escape from the gear that maintain sustainability.

Abstract Cendrawasih Bay and the Pacific Ocean are known as potential fishing areas and as fish spawning locations in Fisheries Management Area 717. Larval dispersal in the waters is strongly influenced by oceanographic parameters. This study was conducted to examine the relationship between oceanographic parameters and fish larval dispersal in FMA 717. This research was conducted using KR Bawal Putih III in November 2019. A number of 42 stations were determined for observation. Environmental parameters included temperature, salinity, dissolved oxygen, chlorophyll-a, turbidity, and photosynthetic active radiation (PAR), were measured using SBE 19 plus V2 CTD while pelagic fish larvae were collected using a bonggo net. Analysis of the correlation of oceanographic parameters with pelagic fish larvae abundance and spatial distribution was calculated using PCA (Principal Component Analysis) statistical analysis. The results showed that the pelagic fish larvae was influenced by temperature, salinity, PAR, chlorophyll-a, turbidity, and DO. Temperature and salinity have a direct interaction to the abundance of pelagic fish larvae.

Large pelagic fish live on the water surface in groups. Skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), mackerel tuna (Euthynnus affinis), mackerel (Scomberomous guttatus) are species of fishes that mainly catches by fishermen using purse seines. This study aims to determine the length and weight of large pelagic fish in the water of Idi Rayeuk and best the fishing season. This research was conducted in one month. Fish samples were collected from fishermen that used purse seine and landed their catches at the Idi Rayeuk Fishing Port, East Aceh. Additionally, the data was derived from the fishing port time-series during 2015 to 2019. The result showed that the yellowfin tuna (Thunnus albacares) has a length between 37 - 58 cm with a weight of 1.0 - 3.2 kg, skipjack tuna (Katsuwonus pelamis) 32 - 58 cm in length and weight 0.5 - 3.0 kg, mackerel tuna has 33 - 54 cm of length with a weight of 0.6 - 2.5 kg, and mackerel has 44 - 66 cm of length and weighing 0.7 - 1.7 kg. Its also found that the peak season for catching yellowfin tuna (Thunnus albacares) and mackerel tuna is May and June, and the lowest season in December for the yellowfin tuna, and December and January for the mackerel tuna. The peak season for skipjack fishing occurs in May, August, and October, and the low season occurs in November and December. Meanwhile, the peak season for fishing mackerel occurs in May, September, and October, while the low season occurs in January, February, and March.Keywords:Fishing seasonLarge pelagicPurse seineIdi RayeukAceh

Abstract Yellowfin tuna Thunnus albacares is one of the major species of tuna caught in the Fisheries Management Area (FMA) 573 of the Indian Ocean. Its production contributed to 35.83% of the total production of tuna in 2013. The study was conducted to assess the population dynamics of this species in FMA 573, based on length-frequency data collected in 2013-2017, and was analysed using FiSAT II software. The results obtained show length-weight relationship of W = 0.000052 FL2.78, negative allometric growth and growth equation of Lt = 194.25 (1-e-0.51 (t + 0.1889)). The length at first capture was estimated at 140 cm FL. Recruitment season occurs between July and September, with a peak in August. The rate of total mortality (Z) was 2.32 yr-1, including natural mortality rate (M) of 0.69 yr-1 and fishing mortality rate (F) of 1.63 yr-1. The exploitation rates of yellowfin tuna were estimated to be 0.70, indicating that it has exceeded the optimum exploitation rate (E = 0.5) and that overexploitation had occurred. There is an obvious need for consistent monitoring and surveillance of fishing fleet, type and size of fishing gear, as well as the fish size and quantity of the catch.

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.

Sumber daya ikan di perairan Indonesia merupakan salah satu modal menuju kemakmuran bagi bangsa, apabila dikelola secara berkelanjutan.Kajian potensi dan tingkat pemanfaatan tahun 2015, merupakan salah satu dasar utama dalam merumuskan pengelolaan tersebut menuju pemanfaatan sumber daya yang lestari bagi kesejahteraan bangsa. Secara keseluruhan komposisi jenis sumber daya ikan di perairan Indonesia didominasi kelompok ikan pelagis kecil sebesar 36 % dan ikan pelagis besar sebesar 25 %. Potensi sumber daya ikan di perairan Indonesia adalah sebesar 9,931 juta ton per tahun dengan potensi tertinggi terdapat di WPP 718 (Laut Arafura) sebesar 1,992 juta ton/tahun (20%), di WPP 572 (Samudera Hindia sebelah barat Sumatera dan Selat Sunda) sebesar 1,228 juta/tahun (12 %) dan di WPP 711 (Selat Karimata, Laut Natuna dan Laut Cina Selatan) sebesar 1,143 juta ton/tahun (12 %). Tingkat pemanfaatan secara keseluruhan terlihat didominasi kondisi overfishing (indikator warna merah) sekitar 49 %, diikuti kondisi fully-exploited (indkator warna kuning) sekitar 37 % dan kondisi moderat (indikator warna hijau) hanya 14 %. Kelompok ikan yang mengalami kondisi overfishing paling tinggi adalah kelompok udang Penaeid, lobster, kepiting dan rajungan, yang mencapai 63 % dari kondisi overfishing saat ini. Dalam perspektif yang demikian, opsi pengelolaan yang harus segera dilakukan adalah mengurangi jumlah upaya penangkapan pada WPP yang mengalami kondisi overfishing serta meningkatkan upaya pada WPP yang tingkat pemanfaatannya masih moderat dan fully exploited.Fish resources within Indonesian waters (i.e. teritorial and archipelagic waters) including Indonesian Economic Exclusive Zone if under sustainably management it would contribute a significant role as a source of nation welfare. Scientific advice on stock status and its exploitation rate are required as an input to support an apropriate fisheries management. Generally, fish resources in these waters are dominated by two main fish groups such as small pelagic fish by 36 % and large pelagic fish by 25 %. Indonesia fish resource in 2015 was estimated for 9,931 million tons/year with comprises of 1,992 million ton/year (20 %) in fisheries management area (FMA) 718 (Arafura sea), 1,228 million/year (12 %) in FMA 572 (western of Sumatera of Indian ocean and Sunda strait) and 1,143 million tons/year (12 %) in FMA 711 (Karimata strait, Natuna sea, and south China sea). Most of fish resources (49 %) were in the status of overfishing with red indicator, folowed by fully-exploited state(37 %) in yellow indicator and only 14 % in the moderate state (green indicator). Among all nine fish groups, the overfishing state (up to 63%) is recorded from group of shrimps (Penaidae), lobster, and crabs. The management options in these prespective is urgently suggested to reduce fishing effort at the level of f.opt (fishing optimum) for overfishing fish groups. Whilts possibly to increase effort for fish groups with fully and moderate exploited state at the level off opt.
