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.

Scomberomorus guttatus is a large pelagic fish commodity in Pangandaran Regency. It has the highest amount and production values, therefore it needs to be maximally utilized but remains its sustainability. The purpose of this research is to determine the most selective fishing gear for Scomberomorus guttatus commodities based on the frequency of Scomberomorus guttatus length, the proportion of the main catch and by-catch in Pangandaran Regency for sustainable and environmentally friendly capture fisheries management. The data used in this study are the number of catches, catch weight and length of the Scomberomorus guttatus catches from gillnet, longline, and beach seine. Data used in research collected during November 2018-January 2019 in Pangandaran Regency. Analysis data used in the study is the analysis of the selectivity of the types of catches and the selectivity of the length of the catchable Scomberomorus guttatus from each of fishing gears. The results showed that of the three fishing gears used to catch Scomberomorus guttatus, gillnet is the most selective and productive fishing gear for utilizing Scomberomorus guttatus commodity because it has a 43,2% of main catch, 84,6% of the feasible Scomberomorus guttatus size. Longline is a fishing gear that is only selective to the length size of the Scomberomorus guttatus that has a percentage of decent size catch equal to 86,4%, while beach seine isn't selective fishing gear and unproductive for Scomberomorus guttatus commodities due to it designed to catch a demersal fish.

Penelitian mengenai perikanan cantrang yang berkaitan dengan sumber daya ikan demersal sebagai hasil tangkapan utama dilaksanakan selama tahun 2006 - 2007. Penelitian ini bertujuan untuk mengetahui fluktuasi bulanan hasil tangkapan cantrang yang berbasis di Pelabuhan Perikanan Pantai Tegal Sari. Metode yang digunakan adalah survei yang meliputi pengambilan contoh dari hasil tangkapan, pencatatan buku bakul dan statistik perikanan pelabuhan. Hasil penelitian menunjukkan bahwa jumlah trip armada cantrang periode 2006 - 2007 didominansi oleh kapal berukuran 21 - 30 GT. Produksi bulanan Pelabuhan Perikanan Pantai Tegal Sari dari tahun 2004 - 2007 berfluktuasi. Secara umum, produksi bulanan pada bulan Nopember 2005 - Desember 2006 jauh lebih tinggi dibanding pada bulan-bulan di tahun 2004 dan 2007. Hal ini karena dipengaruhi oleh fluktuasi jumlah trip dan perkembangan unit penangkapan. Komposisi hasil tangkapan cantrang tahun 2006 berdasarkan pada hasil pengambilan contoh, didominansi oleh ikan coklatan (Scolopsis taeniopterus) (22%), kuniran (Upeneus spp.) (17,4%), dan swangi atau demang (Priachantus sp.) (9,7%). Ratarata laju tangkap pada tahun 2006 dan 2007 berturut-turut 333,6 dan 424 kg/hari. Laju tangkap tahun 2006 cenderung, dipengaruhi oleh fluktuasi musiman, sedangkan laju tangkap tahun 2007 cenderung naik, tidak terpengaruh oleh fluktuasi musiman. Daerah penangkapan armada cantrang yang berbasis di Pelabuhan Perikanan Pantai Tegal Sari adalah di sekitar pantai timur Lampung, Tanjung Selatan (Kalimantan Selatan), dan Tanjung Puting (Kalimantan Tengah). The research on danish seine fishery related to demersal fish resources as the main catch was carried out from 2006 - 2007. The research aimed to know monthly fluctuation of the danish seine catch in Tegal Sari landing base. The survey was conducted by sampling the catch, recording data from retailer’s book and landing base statistic. The results showed that number of trip from 2006 - 2007 was dominated by 21 to 30 GT vessel. Monthly production in Tegal Sari landing base on 2004 to 2007 was fluctuated. Generally, monthly production on November 2005 - Desember 2006 was higher than other months on 2004 and 2007. It was caused by fluctuation of trips number and unit fishing developement. The catch composition in 2006 based on sampling result, was dominated by lattice monocle bream (Scolopsis taenipterus) (22%), goatfish (Upeneus spp.) (17.4%), and purple spotted bigeye (Priachantus spp.) (9.7%). Average of catch rate in 2006 and 2007 was 335.6 and 424 kg per day, respectively. The catch rate in 2006 danish seine, Tegal Sari tended to be influenced by season fluctuation. While catch rate in 2007 increased and was not influenced by season. Fishing grounds of danish seine fleet in Tegal Sari landing base were in eastern coast of Lampung waters, Tanjung Selatan (South Kalimantan) and Tanjung Puting (Central Kalimantan), respectively.

ABSTRACTTernate Island lies in a strategic location as it is situated in the middle of  the main fishing ground for skipjack (Katsuwonus pelamis) fishing using pole and line (huhate) and fish aggregating devices (FADs). As typical pelagic fish, skipjack that is gathered near the water surface is the younger fish, likewise the ones which are caught around FADs. Therefore, this fishing method has caused serious problem due to the domination of young fish and increasing bycatch and discard. The objective of this research is to analyze the size structure of the fork length, appropriate size for catching, catch composition, bycatch and discard level. Pole and line catch samples were collected in 3 months fromMay to July 2018. The results show that in average, skipjack tuna caught in the study location was undersize. The total catch is predominantly targeted fish which has a higher economic value compared to bycatch and discarded fish. Even though bycatch in the pole and line fisheries are low, reduction efforts are still required. which can be done by sorting bycatch and unwanted fish then discard it into the sea when the fish is still alive.Keywords: biology, pole and line, sustainability status, Ternate City ABSTRAKPosisi Pulau Ternate sangat strategis karena berada di tengah perairan yang menjadi daerah operasi penangkapan cakalang (Katsuwonus pelamis) dengan alat tangkap huhate (pole and line) yang dibantu dengan penggunaan rumpon. Sebagaimana ikan pelagis lainnya,  ikan-ikan cakalang yang berkumpul di lapisan permukaan air cenderung tergolong ikan-ikan muda. Oleh karena itu, cakalang yang tertangkap di sekitar rumpon juga cenderung ikan-ikan yang masih muda. Fenomena ini menyebabkan munculnya sebuah masalah besar, yaitu dominasi ikan-ikan muda, selain itu juga sering tertangkap ikan yang bukan target tangkap yang terdiri dari bycatch dan discards. Tujuan dari penelitian ini adalah menganalisis struktur ukuran panjang cagak dan ukuran cakalang layak tangkap, komposisi hasil tangkapan, persentase bycatch dan discards. Sampel hasil tangkapan huhate dikumpulkan selama 3 bulan (Mei sampai Juli 2018). Hasil penelitian menunjukkan bahwa rataan cakalang di lokasi penelitian didominasi ukuran belum layak tangkap. Total hasil tangkapan didominasi ikan target, sementara itu bycatch yang tertangkap memiliki nilai ekonomis yang baik dan tidak ditemukan discards. Walaupun bycatch pada perikanan huhate rendah namun usaha-usaha untuk meminimumkan tetap perlu dilakukan. Salah satu usaha yang bisa dilakukan adalah menyortir hasil tangkapan, ada apabila ada ikan yang akan dibuang ke laut, dilakukan dalam keadaan masih hidup.Kata Kunci: Biologi, huhate (pole and line), status keberlanjutan, Kota Ternate

ABSTRACT The success of baited hook and line fishing gear is determined by the activity of fish in terms of finding and catching food. Adding shrimp extract on bait may increase the fishing power of the bait; but this kind of scientific information, particularly on the bottom hand line is not widely available. This study aimed to determine the effect of shrimp extracts on demersal fish catch in the surrounding fishing ground and to identify the species caught by the bottom hand line. This research was conducted in coastal waters Tateli Weru Village, District of Mandolang, Minahasa in October 2015 which was based on an experimental method. Six units of bottom hand line was operated, where three units using bait of scad mackerel marinated in shrimp extract, and three other units using plain bait of scad mackerel; and the data were analyzed using t-test. Total catches was 60 fish; 38 fish caught by bait with shrimp extract, and 22 fish caught by bait without shrimp extract. The results showed that use of bait with shrimp extract give more catches. Keywords: bottom hand line, extrack of shrimp, demersal fish, Tateli Weru   ABSTRAK Keberhasilan alat tangkap pancing dasar berumpan sangat ditentukan oleh aktivitas hidup ikan dalam hal mencari dan menangkap makanan.

Identification of fish species has an important meaning when viewed from a scientific angle because the entire sequence of subsequent work depends on the results of the correct identification of a species. The purpose of this research is to analyze the types (local, national, scientific name) and types of fishing equipment operating in the Bangka Island. This research was conducted in October 2018 to April 2019 at the Bangka Island. The method was used  purposive sampling. The analysis was carried out by descriptive analysis and PSR (Pressure, State, Response). The result show that there were 30 types of fishing gear that were included in seven classes that are surrounding nets, trawls, seine nets, lift nets, gillnets, traps, hooks and lines. The main fish caught from 30 types of fishing gear used are 73 species which are included in small pelagic fish, large pelagic fish and demersal fish consisting of 38 families. More than 50% of the local names of fish on Bangka Island are different from the names of national fish including Yellow Stalk Fish, in the Bangka area called the Ciu Fish (Selaroides leptolepis), local name Selar Como Fish called Hapau Fish (Atule mate), local name Tetengkek Fish is called Singkur Fish (Megalaspis cordyla), local name Kuwe Onion Trevally Fish is called Sweet Beautiful Fish (Carangoides caeruleopinnatus), Tembang Fish is the local name Tamban Fish (Sardinella gibbosa), Bloso Fish is the local name Buto Cin Fish (Saurida tumbil). Recommendations given are that stakeholders should pay attention to local name so there is no error in data collection and use of enviromentally friendly fishing gear by taking into account the selectivity of fishing gear.

Penelitian terhadap komposisi dan distribusi ikan petek (Leiognathidae) di perairan SelatMakassar (perairan timur Kalimantan), dilakukan pada bulan Juni sampai dengan Juli 2005 dengan menggunakan KM. Bawal Putih. Hasil penelitianmenunjukkan bahwa hasil tangkapan ikan petek (Leiognathidae)merupakan ikan dominan yang ke-2 dengan persentase 17,43%. Pada penelitian ini diperoleh 12 jenis ikan petek (Leiognathidae), dengan 3 genus yaitu Leognathus (7 spesies), Secutor (3 spesies), dan Gaza (2 spesies). Di antara ikan petek yang tertangkap, Leiognathus bindus mempunyai laju tangkap paling tinggi yaitu 12,53 kg per jam, dengan ukuran dominan antara FL 6,5 sampai dengan 7,0 cm, sedangkan Leiognathus splendens merupakan urutan ke-2 dengan laju tangkap 6,66 kg per jam, dengan ukuran dominan antara FL 10,0 sampai dengan 10,5 cm. Distribusi secara vertikal menunjukkan bahwa ikan petek, dominan tertangkap pada kedalaman perairan 21 sampai dengan 30 m, yang berlaku untuk semua jenis atau spesies ikan petek (Leiognathidae). Sedangkan distribusi horisontal ikan petek, dominan tertangkap di sekitar perairan Nunukan dan Tarakan. Research on catch composition, distribution, and some biological aspects of pony fish was conducted in June to July, 2005th using RV. Bawal Putih in the waters of East Kalimantan. Results show that the pony fish (Leiognathidae) provides the second largest component in the catch (17.43%), after Ariidae (30.02%). There were 3 genera of Leiognathidae i.e. Leiognathus (7 species), Secutor (3 species), and Gaza (2 species). Leioghnatus bindus was the highest catch rate within the Leioghnatidae group amoung to about 12.5 kg per hr, with the dominant size of FL 6.5 to 7.0 cm group, followed by Leioghnatus splendens with the catch rate of 6.75 kg per hr and the size of 10.0 to 10.5 cm. Based on depth distribution data it’s likely that the pony fish group was dominantly in the depth range of 21 to 30 m. Based on horizontal distribution data the pony fish group was dominantly in the East-Tarakan waters (1°49’ N–3°55’ N dan 117°53’ E–118° 31’ E).
