Perikanan skala kecil terutama perikanan payang merupakan salah satu tulang punggung mata pencaharian masyarakat pesisir di perairan Karawang, Jawa Barat. Peran nyata aktivitas perikanan pada keanekaragaman sumberdaya hayati laut adalah memanfaatkan sumberdaya hayati perairan laut di kawasan pesisir dengan kondisi kelimpahan sumberdaya ikan yang cenderung berfluktuasi pada tingkat yang relatif rendah. Penelitian dilakukan melalui survey lapang pada kurun waktu Agustus – Nopember 2018 dengan basis data hasil tangkapan dan upaya penangkapan pada rentang waktu 2016-2018. Beberapa data lingkungan terkait ragam keadaan cuaca yang digambarkan oleh data curah hujan, arah dan kecepatan angin digunakan untuk menggambarkan siklus adaptasi nelayan untuk mempertahankan mata pencariannya. Aktivitas penangkapan menggunakan perahu dengan tonase <10 GT dan rerata kekuatan mesin sekitar 20 PK, beroperasi dalam skala harian dengan alat penangkapan ikan utama adalah jaring payang. Perkembangan tahunan indeks kelimpahan sumberdaya ikan dengan alat tangkap payang pada kurun waktu 2004-2008 dan 2015-2018 cenderung menurun. Tahun 2004 nilai indeks kelimpahan sumberdaya ikan sebesar 268 kg/trip menjadi 199 kg/trip pada 2008 dan terus menipis menjadi sebesar 115 kg/trip tahun 2018. Hal ini mengindikasikan usaha perikanan cenderung berada pada kondisi tidak berkelanjutan bila tidak dilakukan pengelolaan. Keberlanjutan usaha perikanan masih dapat diharapkan jika dilakukan perubahan terhadap sistem usaha yang lebih bersifat menjadi gabungan individu perahu yang berukuran kecil menjadi usaha kelompok dengan perahu yang berukuran lebih besar diatas 10 GT dengan daerah penangkapan yang lebih jauh.One day pelagic seine (payang) fisheries, is one of the backbones of coastal community livelihoods in North Karawang waters, West Java. The significant role of fisheries activities to harvest small pelagic fish resource in coastal areas indicated that the monthly CPUE tend fluctuated and stabil at low level. The study was conducted through a field survey in the period August - November 2018 with a database of catches and efforts from 2016-2018. Some environmental data related to various weather conditions illustrated by rainfall data, wind direction and speed are used to describe the adaptation cycle of fishermen to maintain their livelihoods. Fishing activities using boat with tonnage <10 GT and average engine strength of around 20 PK, operating on a daily scale with the main fishing gear is payang net. The average annual catch per trip (CPUE) of payang fisheries within period of 2004-2008 to 2015-2018 tend to decrease. In 2004 the CPUE was 268 kg/trip then 2008 at 199 kg / trip, and continue to lower index in 2018 of 115 kg / trip. This indicates that the fishery business is suspected to be in an unsustainable condition if no sustainable management is carried out. Sustainability of the fisheries business can still be expected if changes are made to the business system which is more a combination of individual small-sized boats into group businesses with boats larger than 10 GT with more distant fishing grounds.

<p>Dua species ikan layang (<em>Decapterus russelli</em> dan <em>D. macrosoma</em>) merupakan komponen utama dalam perikanan pelagis di Laut Jawa dan Selat Makasar, ikan layang biru/malalugis (<em>D. macarellus</em>) adalah jenis dominan di perairan laut dalam sekitar Sulawesi dan Indonesia timur. Analisis struktur populasi tiga spesies layang tersebut dilaksanakan berdasarkan data struktur populasi (mtDNA) untuk memberikan saran pengelolaan berkelanjutan dan evaluasi WPP (Wilayah Pengelolaan Perikanan). Hasil menunjukkan dari masing-masing dua unit stok tiap species yang terditeksi setiap unit stok/unit biologi yang juga merupakan unit manajemen memiliki sebaran ‘spatial’ yang tidak selalu terbatas di suatu WPP, tetapi sangat dimungkinkan menyebar ‘lintas’ WPP (dua atau lebih WPP) yang umumnya memiliki karakteristik habitat sama; sedangkan keragaman habitat seringkali terlihat dalam satu WPP. Untuk tujuan pengelolaan secara berkelanjutan, pengelolaan sumber daya ikan pelagis kecil disarankan berbasis pada unit manajemen serta meliputi daerah sebaran dari unit manajemen tersebut. Daerah sebaran tersebut mungkin terdapat dalam satu WPP, tetapi seringkali akan meliputi dua atau lebih WPP (lintas WPP). Stok layang (<em>Decapterus russelli</em> dan <em>D. macrosoma</em>) Laut Jawa dan Selat Makasar (dua WPP) disarankan dikelola sebagai satu unit manajemen; sedangkan, stok malalugis yang memiliki ciri genetic sama yang tersebar lintas WPP Selat Makasar (bagian selatan), Teluk Bone, Teluk Tolo, Laut Flores, Laut Banda, Teluk Tomini dan Laut Maluku, disarankan dikelola sebagai satu unit manajemen; unit stok Laut Sulawesi dikelola secara terpisah sebagai unit manajemen yang berbeda. Dalam konteks perikanan layang di Laut Jawa fakta struktur populasinya (kasus D. macrosoma) tidak menunjukkan indikasi migrasi layang dari arah timur (Laut Banda atau Laut Flores) ke arah Laut Jawa seperti dihypotesakan oleh Hardenberg (1938).</p><p> </p><p>Two species of scads (Decapterus russelli and D. macrosoma) is a major component in the pelagic fisheries in the Java Sea and Makassar Strait, the mackerel-scads / malalugis (D. macarellus) is the dominant species around Sulawesi and the eastern waters of Indonesia. Population structure anlyses of those three species of layang was implemented to give a sustainable management<br />options and FMA evaluation, based on the population structure data (mtDNA). Results show from each two stock units by species detected each stock unit / units of biology is a management unit which is have a spatially distribute not only in one WPP/FMA, but it is possible to spread ‘cross’ of FMA (two or more FMA ) which is generally has the same habitat; whereas, the diversity of habitats are often exist. For the purpose of sustainable management, a management of small pelagic fish is recommended based on management units that covers an area of distribution<br />of its management unit. This distribution area may be contained in one FMA, but often will include two or more FMA. Stock of scads (Decapterus russelli and D. macrosoma) in the Java Sea and Makassar Strait (two WPP) suggested to manage as a unit of management; whereas, stock malalugis with the same genetic characters that are spread across in the FMA of Makassar Strait (south), Bone Bay, Tolo Bay, Flores Sea, Banda Sea, Tomini and Maluku Sea, it is suggested to managed as a single unit of management; however, the stock of Celebes Sea are managed separately as different management units. In the context of Java Sea fisheries the fact of the population structure (in case of D. macrosoma) did not shows an indication of west ward migration (Banda Sea-Flores Sea) to<br />the Java Sea like a Hardenberg (1938) hyphotese.</p>

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.

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.

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.
