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

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.

Suatu riset yang bertujuan untuk mendapatkan data dan informasi tentang aktivitas penangkapan dan distribusi udang galah (Macrobrachium rosenbergii) di daerah aliaran Sungai Kapuas, Kalimantan Barat telah dilakukan dari bulan Juni sampai dengan Desember 2005. Riset dilaksanakan dengan metode survei dengan cara mendatangi lokasi-lokasi tempat ada aktivitas penangkapan udang galah (Macrobrachium rosenbergii). Frekuensi survei 2 kali pada musim kemarau dan 2 kali pada musim hujan. Wilayah perairan yang disurvei adalah daerah aliaran Sungai Kapuas dalam Kabupaten Pontianak, Kota Pontianak, Kabupaten Sanggau, dan Kabupaten Sintang. Data dianalisis dengan metode deskriptif dan tabulasi. Dari survei ditemukan 9 jenis alat tangkap yang digunakan nelayan untuk menangkap udang galah (Macrobrachium rosenbergii) yaitu pancing, rawai, bubu, jala, jaring, blad, rompong, stroom, dan pukat rantau. Catch per unit of effort terkecil terjadi pada alat tangkap bubu yaitu 1,39 g per per unit per jam, terbesar adalah jala yaitu 416,67 g per unit jala per jam. Intensitas penangkapan terlihat dominan di perairan bagian hilir mencakup wilayah Kabupaten dan Kota Pontianak. Distribusi ukuran bobot individu udang galah (Macrobrachium rosenbergii) yang banyak tertangkap oleh nelayan (nilai modus) dari 4 kali survei bervariasi antara 17,73 sampai dengan 40,00 g (Kabupaten Pontianak); 19,31 sampai dengan 47,01 g (Kota Pontianak), 17,79 sampai dengan 45, 35 g (Kabupaten Sanggau), dan antara 25,08 sampai dengan 85,52 g (Kabupaten Sintang). Kualitas air pada habitat tempat udang tertangkap di daerah aliaran Sungai Kapuas dalam batas-batas yang layak untuk mendukung kehidupan ikan dan udang. A study aimed to obtain recent data and information about capture activities and distribution of giant freshwater (Macrobrachiumrosenbergii) prawn in Kapuas River,West Kalimantan was conducted from June to December 2005. Survey method was used in each research stations that are Pontianak district, Pontianak City, Sanggau, and Sintang districts. The stations were selected based on fishing activities and habitat condition. Field survey was completed by conducting 4 times surveys including dry and rainy seasons. Data collected were analyzed by using tabulation and descriptive method. The results showed that there were 9 types of fishing gears commonly used to catch giant freshwater (Macrobrachium rosenbergii) prawn. These fishing gears were : hook and line, long line, pot traps, cast net, gill net, barrier traps, surrounding net, electrical fishing, and surrounding net. Catch per unit effort of the cast net was the highest (416,67 gr per unit per hour, whereas, pot trap was the lowest (1,39 g per unit per hour). Water quality in each stations indicated suitable for aquatic organisms. The capture intensity showed that in downstream(Pontianak District and Pontianak City) was more dominant than in upstream (Sanggau and Sintang Districts). Distribution of weight based on modus indicated variation in each stations, which are 17.73 to 40.00 g (Pontianak District), 19.31 to 47.01 g (Pontianak District), 17.79 to 45.35 g (Sanggau District),and 25.08 to 85.52 g (Sintang District).

The Status

Fish biodiversity on Hau (Bassac) river was investigated to assess the status of species composition and fishing by fishing gears during a year. Sampling was implemented monthly at the upper part (An Giang province), middle part (Can Tho City) and lower part (Soc Trang province) of Hau River using trawl net as main sampling gear. Additionally, fish composition was also recorded from four other most popular fishing gears including cast net, gill net, fixed net and hook operated in the study sites. Fish species composition was determined by fishing gears and their abundance (CPUE) was calculated only from the main sampling gear (trawl net). The results showed that a total of 176 fish species belonging to 16 orders and 49 families was recorded. Perciformes was the most abundant group with 51 species followed by Cypriniformes with 46 species. The number of fish species was decreasing from upper part to lower part. Trawl net was considered the most destructive gear as up to 145 fish species caught by this device, followed by gill net with 98 species, fixed net 75, cast net 57, and hooks 16 species. CPUE was very low ranging from  0.53 kg.ha−1 h−1 to 26.30 kg.ha−1 h−1. Higher CPUE was recorded at lower part in compared to upper part and middle part, and at dry season in compared to rainy season. Regulation on fishing gears, fishing ground and season should be taken into consideration to protect and conserve the resources.

Understanding global fisheries patterns contributes significantly to their management. By combining harmonized unmapped data sources with maps from satellite tracking data, regional tuna management organisations, the ranges of fished taxa, the access of fleets and the logistics of associated fishing gears the expansion and intensification of marine fisheries for nearly a century and half (1869–2015) is illustrated. Estimates of industrial, non-industrial reported, illegal/unreported (IUU) and discards reveal changes in country dominance, catch composition and fishing gear use. Catch of industrial and non-industrial marine fishing by year, fishing country, taxa and gear by 30-min spatial cell broken to reported, IUU and discards is available. Results show a historical increase in bottom trawl with corresponding reduction in the landings from seines. Though diverse, global landings are now dominated by demersal and small pelagic species.

Ikan terubuk (Tenualosa macrura Bleeker, 1852) merupakan komoditas perikanan yang penting di Bengkalis, Provinsi Riau. Populasi terubuk di Bengkalis sangat menurun akibat dieksploitasi meskipun pembatasan penangkapan juga telah diterapkan melalui metode konservasi. Upaya selain konservasi juga melalui budidaya ikan namun upaya ini terkendala oleh ketersedian ikan terubuk hidup baik sebagai induk maupun ikan dewasa. Tulisan ini membahas hasil uji coba pengoperasian alat penangkap ikan jaring dua lapis untuk menangkap ikan terubuk hidup. Uji coba penangkapan dilaksanakan pada tahun 2015 – 2016 di perairan Selat Bengkalis dan sekitarnya. Hasil uji coba penangkapan menunjukkan bahwa jenis ikan yang dominan tertangkap adalah ikan biang-biang (Setipinna breviceps) dan nomei (Harpodon sp). Laju tangkap jaring dua lapis terhadap ikan terubuk berkisar 0,7 - 2,6 ekor/setting. Jumlah ikan terubuk yang tertangkap dalam kondisi hidup mencapai 27,1% dari total tangkapan ikan terubuk. Nilai ukuran panjang pertama kali tertangkap ikan terubuk dengan jaring dua lapis (Lc) yaitu 17,43 cmFL. Terubok (Tenualosa macrura Bleeker, 1852) is an important fish commodity in Bengkalis, Riau Province. The terubok resosurce in Bengkalis is heavily degraded due to the high exploitation even fishing limitation was applied in term of species conservation. Conservation efforts through fishculture are constrained by the availability of live terobuk fish as both parent and adult fish. This paper present the results of fishing trial of double-net fishing gear for catching alive terubok fish. Fishing trial was conducted in 2015-2016 periods in Bengkalis strait waters and its adjascent. The results shown that the dominant fish catches of doublé net were Shorthead hairfin anchovy (Setipinna breviceps) and bombay duck (Harpodon sp). Double gill net catch rate for terubok were between 0,7 -2,6 fish/setting. Number of alive terubok fish was 27,1% of total terubok catches, length of first capture (Lc) value of terubok by using doublé net was 17.4 cm FL.

Destructive Fishing

Peristiwa overfishing semakin marak terjadi di beberapa wilayah perikanan Indonesia akibat penggunaan alat tangkap yang merusak (destruktif). Jika hal ini terus dilakukan, maka kelestarian sumberdaya dikhawatirkan akan semakin menurun. Maka dari itu dibutuhkan strategi agar usaha perikanan tangkap ramah lingkungan secara ekologi dengan cara mengidentifikasi alat tangkap berdasarkan kriteria Code of Conduct for Responsible Fisheries (CCRF). Tujuan dari penelitian ini adalah untuk menganalisis alat tangkap ramah lingkungan di PPI Celong berdasarkan Sembilan kriteria CCRF. Metode penelitian yang digunakan adalah deskriptif mengenai alat penangkapan ikan yang ramah lingkungan di Pangkalan Pendaratan Ikan (PPI) Celong pada bulan Desember 2017 dengan wawancara dan observasi lapangan. Responden diambil secara sensus sebanyak 121 orang. Hasil analisis ramah lingkungan menghasilkan skor 17,87 pada arad, 27,44 pada trammel net, dan 28,40 pada gill net. Kesimpulan yang diperoleh dari penelitian ini adalah status alat tangkap arad tidak ramah lingkungan, trammel net ramah lingkungan, dan gill netsangat ramah lingkungan. Arad termasuk dalam kategori tidak ramah lingkungan karena cara pengoperasiannya yang tidak selektif dan merusak dasar perairan. Overfishing are increasingly prevalent in some Indonesian fishery areas due to the use of destructive fishing gear. If it continues, then the sustainability of resources feared will decrease further. Therefore a strategy is needed for eco-friendly fishery business by identifying fishing gear based on the criteria of Code of Conduct for Responsible Fisheries (CCRF). The purpose of this research is to analyze the eco-friendly fishing gear at Celong Fishing gear based on Nine criteria of CCRF. The research method used is descriptive of eco-friendly fishing gear at Celong Fishing Port in December 2017 with interviews and observations. Respondents who were taken by census was 121 respondents. The results of eco-friendly analysis resulted in a score 17.87 for  arad, 27.44 for trammel net, and 28.40 for gill net. The conclusions obtained from this research are arad status is not eco-friendly, trammel net is eco-friendly, and gill net is very eco-friendly. Arad is categorized as eco-unfriendly due to its non-selective way of operating and damaging the sea base.

Fish Species Diversity

Fish species, fishing gear and crafts in the most polluted river Buriganga were inventorial. During December, 2012 to November, 2013, a total of 56 fish species belonging to 20 families and 9 orders were recorded. Cypriniformes observed to be the most dominant order with 18 species (32%). The highest fish diversity was recorded during monsoon season, and lowest during winter. Maximum diversity variance (7.616 ± 2.76 Sd) observed in the monsoon season for 56 species (220 individuals). Also 12 different types of gears of two categories (active and passive) and two types of crafts were observed to be used for fishing in the study area. The highest number of species of fishes (n = 56) recorded in August and lowest (n = 3) in April and May 2013. Strong correlation between water depth and number of fish species (r = 0.74) and fishing activities (r = 0.96) was observed.Bangladesh J. Zool. 45(1): 11-26, 2017

Artisanal fisheries in the coastal zone of Itaipu-RJ play an important role in the local market, but little is known about production and productivity of the fisheries. From April 2001 to March 2003, we monitored a total of 618 landings from the beach-seine (99), the gill nets ("corvineira" - 331, "linguadeira" - 40 and "rede alta" - 25), the hook and line (98), the squid jigging (17), and the spear fishing and trap fisheries (five and three, respectively). The total monitored production was 21866 kg and the catch per unit effort (CPUE) 35.4 kg.trip-1. Considering the number of effective fishing days and the average daily production per fishing gear, the annual production was estimated at 136687 kg (0.2% of the state's production in 2004). Predominant resources were: Micropogonias furnieri,Trichiurus lepturus, squids (Loligo spp.), clupeiform fishes (Sardinella brasiliensis, Cetengraulis edentulus, Pellona harrowerii and Harengula clupeola), Eucinostomus spp., Cynoscion spp., Menticirrhus spp., Caranx crysos and Selene setapinnis. The combined analysis using hierarchical and non-hierarchical classification methods, separated four fishing gears and five species groups, based on their similarity patterns, identifying gears that most effectively capture the different fish groups. The beach-seine was less selective and most productive fishery in the summer. The "corvineira" was the second most productive fishery with higher yields in the summer and fall. Catches of "linguadeira" included rays and Paralychthys spp., wherereas the "rede alta" caught primarily M. furnieri,Mugil spp. and sharks.
