ABSTRACT<br />Effort to exploitation the fishery resources can do in various ways, catching effort by use of hand line is one of the efforts in the field of fisherie. The study was conducted in the Sabutung Island Waters of Pangkep Regency, aims was to investigate the effect of different of hook size and the species composition of the catch of hand line using different of hook size. The effectiveness of hook size is determined by the highest of catches.The method used is experimental fishing on the fishing operation of hand line during 30 trips. Data analysis used normality test and ANOVA test done with SPSS 16.0. The results showed that the differences between hook size number 10 with number 8 and 12 gave influences to the amount of catch. It’s showed by sig score hook size no.10 is 0,00 and sig score hook size no.8 and 12 is 0,00 which them have sig score less than 0,05 and it meant H0 pushed away so it concluded that the hook size influenced the fishing catch. The compositions of fish catch during the study based on the amount and weight were short mackerel, Bigeye scad, Indian scad, yellow tail and diodon histrix. Short mackerel were the most species of fish caught during the research that is equal to 41,2% of the 364 tail of the total catch.<br /><br />Keywords: hand line, hook size, small pelagic fish<br />-------<br /><br />ABSTRAK<br /><br />Usaha mengeksploitasi sumber daya perikanan dapat dilakukan dengan berbagai macam cara, salah satu diantaranya adalah usaha perikanan tangkap dengan menggunakan pancing ulur (hand line). Penelitian dilakukan pada September-Nopember 2012 di Perairan Pulau Sabutung Kabupaten Pangkep, bertujuan untuk mengetahui pengaruh perbedaan ukuran mata pancing dan komposisi hasil tangkapan dari tiga ukuran mata pancing yang berbeda sehingga diperoleh ukuran mata pancing yang efektif.

Studies on the exploitation and catch fluctuations of pelagic fishes have been undertaken in order to understand the fishery systems, annual and seasonal change of fishing effort and catches, as well as species composition. The study was based on the daily monitoring data of the purse seiners. The results showed that generally the fishing activities is one day fishing, the increase of fishing effort reflected in the number of fishing units and the number of trip, while the trend of production and catch rate were fluctuated by either annual or seasonal; the peak of catch rate was occurred in 2007, 2008 and 2012 periods, during December to June were low catches, and are going in the peak season in September-October. The lowest catch rate is about 100kg/trip and the maximum of 4.3 tons/trip (the average of 1.3 tons/trip), however the fail of fishing was often occurs and reached 30% of the total number of trips; the failed fishing was decline from year to year. The catch rate (kg/trip/day) was showed a pattern fluctuations; the small pelagic fish mainly the scads (Decapterus spp.) and clupeids (Bali sardine, Sardinella lemuru), respectively 33% and17%, whereas the dominan large pelagic fish is ‘tongkol’/frigate tuna (Auxis thazzard). The changes of species domination was occurred either in annually or seasonally.

Bagan perahu merupakan salah satu jenis alat tangkap di PPN Karangantu yang beroperasi pada malam hari. Bagan perahu menarik ikan target tangkapan yaitu ikan pelagis kecil fototaksis positif menggunakan atraktor cahaya berupa lampu. Salah satu kendala nelayan bagan perahu adalah pencahayaan lampu mengalami pembiasan. Penggunaan lampu bawah air bertujuan untuk mengurangi pembiasan. Tujuan dari penelitian ini adalah mengetahui pengaruh penggunaan lampu bawah air terhadap hasil tangkapan bagan perahu dan mengetahui komposisi hasil tangkapan bagan perahu dengan dan tanpa lampu bawah air. Penelitian ini dilakukan selama 10 trip menggunakan metode experimental fishing. Selisih berat total hasil tangkapan antara bagan perahu dengan dan tanpa lampu bawah air pada trip 1 sebesar 33,4 kg, trip 2 sebesar 38,9 kg, trip 3 sebesar 31,1 kg, trip 4 sebesar 41,1 kg, trip 5 sebesar 28,8 kg, trip 6 sebesar 30,5 kg, trip 7 sebesar 35,4 kg, trip 8 sebesar 34,3 kg, trip 9 sebesar 38,7 kg dan trip 10 sebesar 31,6 kg sehingga menunjukkan hasil tangkapan lebih banyak bagan perahu dengan lampu bawah air. Hasil tangkapan utama bagan perahu adalah ikan Teri (Stolephorus sp.) dan Cumi-cumi (Loligo sp.). Hasil tangkapan sampingan bagan perahu antara lain ikan Petek (Leiognathus sp.), Tembang (Sardinella sp.), Lemuru (Amblygaster sirm), Selar Kuning (Selaroides leptolepi) dan Layur (Lepturacanthus savala). Kesimpulan yang dapat diambil yaitu terdapat pengaruh antara lampu bawah air dengan hasil tangkapan pada bagan perahu. Boat lift net is one type of fishing gear at PPN Karangantu which operates at night. Boat lift net attracts the target catch fish, the small pelagic fish is positive phototaxis using a light attractor in the form of a lamp. One of the constraints of fishermen on the boat chart is that the lighting has experienced refraction. Underwater lamp aims to reduce refraction.The purpose of this research is to know the effect of underwater lamp usage on boat lift net fishing catch and to know the composition of boat lift net with and without using underwater lamp. This research was conducted for 10 trips using experimental fishing methods. The difference in total catch of boat lift net with and without underwater lamp on trip 1 is 33,4 kg, trip 2 is 38,9 kg, trip 3 is 31,1 kg, trip 4 is 41,1 kg, trip 5 is 28,8 kg, trip 6 is 30,5 kg, trip 7 is 35,4 kg, trip 8 is 34,3 kg, trip 9 is 38,7 kg and trip 10 is 31,6 kg so it shows the catch is more the boat lift net with underwater lamp. Fish targets of the boat lift net are Anchovy (Stolephorus sp.) and Cuttlefish (Loligo sp.). The bycatches of boat lift net are Pony fish (Leiognathus sp.), Fringescale sardinella (Sardinella sp.), Indian sardinella (Amblygaster sirm), Trevally (Selaroides leptolepi) and Hairtail fish (Lepturacanthus savala). The conclusion that can be drawn that there is an influence between underwater lamp and catches on the boat lift net.

Fish Catch

The purse seine is the dominant fishing tool at the Birea Fish Landing Base (FLB) which generally catches small pelagic fish. Handling fresh fish is an important part of the chain of the fishing industry. The problem that dominates fishermen and owners is the decline in the quality of fish caught due to fishing time at sea, so that preservation technology is needed that is able to maintain the quality of the fish longer from being caught until landed in the fishing port.The purpose of this study was to analyze the handling and quality of the purse seine fish catch and to analyze the handling and quality of the fish catch after landing from the purse seine ship. This research was conducted on a purse seine vessel in Bantaeng Regency from February to March 2020. Of the five vessels that were the object of research, vessels with better fish quality were vessels that used management with a ratio of 1: 1 meaning 1 kg for 1 kg of fish. The behavior management of fish traders in the market and the travel time from the fish caught to the market are factors that influence the effect of the decline in fish quality.

<p>Ikan Malalugis adalah ikan pelagis kecil yang merupakan hasil tangkapan utama nelayan di perairan Laut Sulawesi. Pada tahun 2012 dilaporkan bahwa perikanan pelagis kecil menjadi salah satu hasil perikanan yang penting, dan hasil tangkapan yang dominan dari perikanan pelagis kecil tersebut adalah ikan malalugis biru (Decapterus macarellus). Jenis ikan malalugis memiliki sifat bermigrasi dan membentuk gerombolan kecil yang mana sangat dipengaruhi oleh kondisi lingkungannya. Tipe arus pasut di Teluk Manado (Laut Sulawesi) merupakan arus pasut bolak balik (reversing current). Banyaknya arus yang begitu aktif merupakan salah satu faktor yang mendukung habitat ikan malalugis. Diduga kekhasan sifat distribusi arus di daerah laut Sulawesi ini yang membuat kelimpahan ikan malalugis relatif tinggi di perairan Sulawesi Utara dibandingkan dengan daerah perairan lainnya di Indonesia. Kelimpahan ikan malalugis yang tinggi mendorong ikan ini menjadi komoditas penting dalam sektor perikanan di Laut Sulawesi. Meski demikian pada tahun 2012 dilaporkan bahwa tingkat produksi ikan malalugis mengalami penurunan. Hal ini diduga karena terlalu tingginya tingkat eksploitasi atau diakibatkan oleh adanya perubahan dalam kondisi ekosistem ikan tersebut di Laut Sulawesi. Oleh karena itu studi ini dilakukan untuk mengkaji tingkat daya dukung lingkungan terhadap keberlangsungan sumberdaya perikanan malalugis di wilayah perairan Laut Sulawesi.</p><p><br /><em>Malalugis fish is a small pelagic fish that constitute the main catch of fishermen in the waters of North Celebes Sea. In 2012 it was reported that small pelagic fishery became one of the important fishery products and it was dominated by the species of Malalugis (Decapterus macarellus). This species has a typical behavior which was highly mobility and forming fish schooling and strongly influenced by environmental conditions. The type of tidal current in North Sulawesi coast is reversing current. This kind of current could make a very active current in the water which is suitable for the habitat of Malalugis. This distinctiveness of current was considered as a trigger for relatively high abundance of Malalugis in this area compared to its </em><em>abundance in other water body of Indonesian territory. In 2012, total catch of this species has been reported to be decreased; thismay caused by either high level of exploitation nor changing on its habitat or even both. This study was conducted to investigate the capability of ecosystem and habitat of Malalugis to support its sustainability.</em></p>

One of potential fishing grounds for small pelagic fish in Southeast Mallucas Regency is Rosenberg Strait waters. In this region, a study on the effect of different light intensities of floating lift net on fish catches was carried out. The analyses were done on light distribution of 4 light intensities different: Petromaks Lamp and Underwater Lamps of each 18 watt, 36 watt and 54 watt. This study showed that catches of floating lift net using different light intensities were statistically significantly different. The use of 36 watt and 54 watt underwater lamp yielded the same amount of catches but higher than that of 18 watt-underwater lamp and petromaks, both in number and species. Catches consisted of 17 species, 16 fishs and 1 mollusca. Number of species and size also varied with light intensity used. There were 13 fishs species dominated by Stolephorus indicus as much as 46.9 kg or 22% for petromaks catches, 14 fishs species dominated by Rastrelliger kanagurata as much as 64 kg (31%) for 18 watt underwater lamp, 17 fishs species dominated by Rastrelliger kanagurata as much as 76 kg (28%) for 36 watt underwater lamp, and 15 fishs species dominated by Stolephorus devisi as much as 54.8 kg (22%) for 54 watt underwater lamp, respectively. Based on the results, it is recommended that the use of light intensity in fishing operations of floating lift net should be 36 watt and 54 watt underwater lamps, due to high catches, both in number and species. Beside that, since light fishing has also caught illegal fish size, number of this fishing gear type should be controlled.

Lembeh Bay waters possess sufficient potency of small pelagic fish resources that could be managed for people prosperity, particularly fisheries communities. One of the fishing gears operated in Lembeh Strait is aerial traps. The success of aerial traps operation is the availability of target fish resources, the control of target fish behavior, and hauling time. One of the influencing factors of net hauling time isroller that functions to lower and lift the net in light fishing. This study utilized 3 different roller diameters, 10 cm, 15 cm, and 20 cm,installed over each aerial traps and simultaneously operated. Fishing operations were done 7 times once a day, from October 21th, 2017, and October 23th to 28th, 2017. Results found that the roller size highly significantly affected the time of net hauling and catches, 262 seconds for 10 cm diameter, 215.86 seconds for 15 cm diameter, and 178.86 seconds for 20 cm diameter, respectively. Total catches obtained in 3 aerial traps using different rollers were 4450 kg (18.43 %) of mackerel (Decapterus sp), 5250 kg (21.74 %) of yellowstripe scad (Selaroides sp), 5500 kg (22.77 %) of bullet tuna (Auxisrocii), 5750 kg (23.81 %)of sardines (Sardinella sp), and 3200 kg (13.25 %) of squids (Loligo sp).Keywords: roller diameters, aerial traps. ABSTRAKPerairan Selat Lembeh memiliki potensi sumberdaya ikan pelagis kecil yang cukup potensial untuk dikelola bagi kemakmuran masyarakat pada umumnya dan khusunya masyarakat nelayan. Salah satu alat tangkap yang diusahakan oleh nelayan yang berkegiatan di perairan Selat Lembeh adalah bagan. Keberhasilan pengoperasian bagan adalah tersedianya sumberdaya ikan target, pengendalian tingkah laku ikan target serta waktu pengangkatan atau penarikan jaring (cang). Salah satu faktor yang mempengaruhi waktu pengangkatan jaring yaitu roller. Pada bagian atas rumah bagan terdapat alat penggulung (roller) yang berfungsi sebagai katrol untuk menurunkan dan mengangkat jaring bagan pada malam hari (light fishing) terutama pada hari yang gelap dengan menggubakan lampu sebagan alat bantu penangkapan. Perlakuan yang digunakan dalam penelitian ini adalah 3 (tiga) penambahan diameter roller dengan ukuran berbeda yaitu: 10 cm, 15 cm, dan 20 cm yang dipasang pada tiap bagan (1 bagan 1 ukuran roller) dan dioperasikan secara bersamaan. Pengoperasian dilakukan sebanyak 7 (tujuh) kali pada hari-hari yang berbeda, yaitu dilakukan pada bulan Oktober 2017, dimulai pada hari Sabtu tanggal 21, Senin tanggal 23 – Sabtu tanggal 28. Perbedaan beberapa ukuran roller pada bagan apung, berpengaruh sangat nyata terhadap waktu penarikan jaring dan hasil tangkapan yaitu lebih cepat, dengan rincian waktu pada penambahan diameter 10 cm 262 detik, diameter 15 cm 215,86 detik, dan diameter 20 cm 178,86 detik. Hasil tangkapan total yang diperoleh selama pelaksanaan penelitian pada 3 alat tangkap bagan dengan ukuran penambahan sampul roller yang berbeda sebanyak 4450 kg (18,43 %) malalugis (Decapterus sp), 5250 kg (21,74 %) tude (Selaroides sp), 5500 kg (22,77 %) deho (Auxisrocii), 5750 kg (23,81 %) sardin (Sardinella sp) dan 3200 kg (13,25 %) cumi (loligo sp).Kata-kata kunci: diameter roller, bagan apung.

Main Factor

Generally, fishery resources are open access which means that anyone can participate without having these resources. This is shown by an increase in the utilization of fish resources that will lead to a crisis in which when the rate of exploitation goes beyond the ability of regeneration that makes the catches more economical (economic overfishing). Moreover, this will take place in conditions of uncontrolled fishing. The main factor causing this crisis is the uncontrolled human intervention toward the existing fishery resources. The exploitation of these resources can lead to an imbalance between the input and the potential capture of fish resources so that it can lead to over-fishing, overcapacity, inefficiency arrest, resource rents decline, degradation of the resource stock and a decrease in production. The degradation impact of small pelagic fish resource, especially Layang fish in Ambon also is the reduction of producer welfare, especially the welfare of fishermen and coastal communities. This is due to, among others, the lack of control from the government as the authors,, and the lack of understanding of resource actors (local fishermen) about the nature of fish resources which are open access. Thus, the calculation of the depreciation of small pelagic fish resources, especially lyang fish, and welfare aspects which are considered important to know as a point of reference as well as an early warning signal to determine whether the extraction of small pelagic fish resources, especially layang fish in Ambon has exceeded their capabilities.
