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.

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.

Studies were conducted on catch assessment of some artisanal marine fishing gears operated in Cox’s Bazar and Teknaf areas from April 2014 to April 2015. Sixteen types of fishing gears were identified, of which gill net, beach seine net, estuarine set bag net, marine set bag net and trammel net occupy major fishing activities. Although estuarine set bag net (ESBN) is a legally restricted fishing gear recorded the highest catch per unit effort (CPUE) (110 kg/gear/day) in July followed by marine set bag net (MSBN) (105 kg/gear/day) in Cox’s Bazar and the highest CPUE was recorded 100 kg/gear/day by ESBN in June followed by MSBN (90 kg/gear/day) in Teknaf. Out of 52 species of fishes, the major fish species abundantly caught by these gears were Poa (Otolithoides argenteus), Churi (Trichiurus haumela), Loittya (Harpadon nehereus), Ranga choukha (Lutjanus johni), Lal poa (Johnius argentatus), Olua (Coilia dussumieri), Rup chanda (Stromateus chinensis), (Stromateus argenteus) and Ilish (Tenualosa ilisha). Besides these fish species, 10 commercially important shrimp species and 3 important crab species were also recorded during the study period. The peak season of availability of most fish species was June and July while lean season was December and January. This study indicated that Otolithoides argenteus) was the dominant fish species followed by Trichiurus haumela, Harpadon nehereus and Coilia dussumieri.Progressive Agriculture 27 (2): 228-234, 2016

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.

Fishery potential utilization in the waters of Aceh Jaya was dependent on fishing technology and still limited.The type of fishing gears which used in Aceh Jaya were beach seine, line fishing, gillnet, and liftnet. Liftnet used by Patek fishermen was floating liftnet. Bagan was classified in light fishing. The type of lamps which used by fishermen was fluorescent and set on the surface, whereas the surface lamp was less effective for use. This research used underwater lamp. The aims of this research were to get underwater lamp construction and determine the LED effectiveness. Construction of underwater lamp designed an innovation, that was the dimmed, so that fish which have aggregated by the light would more focus to the liftnet. The research methods were descriptive, fishing gear construction design, experiment or experimental fishing. Underwater lamp lights could help Patek fishermen for fishing and  got maximum catches. Total catches by using fluorescent light were 2343 kg. Meanwhile, total catches with underwater lamp were 3779 kg. Fish species that were caught by lift net were anchovy, peperek, tembang, mackerel, selar, japuh, and layur for 10 trip, 5 trip in the dark and the bright moon. Seen that there were differences of catches amount and composition by using fluorescent lamps and underwater lamp. The results of research it was concluded effective underwater lamp as a tool in fisheries liftnet.
