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.

ABSTRACT<br />Sunda Strait is waters which have great fishery potential in Indonesia. Catches of the Sunda Strait were landed in Pandeglang Regency, one of which is in the Coastal Fishing Port (PPP) Labuan. Purse seine is fishing gear with the highest production in Sunda Strait. Species targets of purse seine are Fringescale sardinella, Mackerel, Short mackerel, Indian mackerel, Kawakawa, and Indian scad. The high price of the fish lead purse seine operation continuously. Increasing purse seine operation can lead to the scarcity fishery resources. Therefore, a study about fish exploitation rate is needed to know the utilization status. The purpose of this study was to evaluate the exploitation rate of multispesies fisheries which caught by purse seine in Sunda Strait based on catch data landed data in PPP Labuan. This study used the ELEFAN I methods and Pauly formula. The result showed that the exploitation rate of fish resources for female and male fringescale sardinella are 0,79 and 0,70; Island mackerel are 0,78 and 0,60; short mackerel are 0,85 and 0,88; Indian mackerel are 0,80 and 0,83; kawakawa are 0,95 and 0,90; Indian scad are 0,75 and 0,62. Nowadays, all fish which caught by purse seine in the Sunda Strait has been indicated to over-exploitation.<br /><br />Keywords: exploitation rate, pelagic fish, purse seine, Sunda strait<br />------<br /><br />ABSTRAK<br /><br />Selat Sunda merupakan perairan yang memiliki potensi perikanan yang cukup besar di Indonesia. Hasil tangkapan ikan dari Selat Sunda didaratkan di Kabupaten Pandeglang, salah satunya adalah di Pelabuhan Perikanan Pantai (PPP) Labuan. Pukat cincin merupakan alat tangkap dengan produksi paling banyak di Selat Sunda. Spesies yang merupakan target tangkapan pukat cincin yaitu tembang, kembung, kembung perempuan, kembung laki-laki, tongkol, dan layang. Harga jual ikan yang tinggi menyebabkan pengoperasian pukat cincin terus ditingkatkan. Pengoperasian pukat cincin yang terus meningkat dapat menyebabkan kelangkaan terhadap sumber daya perikanan. Oleh karena itu, perlu dilakukan kajian mengenai laju eksploitasi sumber daya ikan agar diketahui status pemanfaatannya. Tujuan penelitian ini adalah untuk mengevaluasi laju eksploitasi multispesies yang tertangkap pukat cincin di Selat Sunda berdasarkan data tangkapan yang didaratkan di PPP Labuan. Pada penelitian ini digunakan metode ELEFAN I dan rumus Pauly. Hasil analisis menunjukkan bahwa laju eksploitasi sumber daya ikan berturut-turut betina dan jantan spesies tembang sebesar 0,79 dan 0,70; kembung 0,78 dan 0,60; kembung laki-laki 0,85 dan 0,88; kembung perempuan 0,80 dan 0,83; tongkol 0,95 dan 0,90; layang 0,75 dan 0,62. Saat ini kondisi semua ikan hasil tangkapan dominan pukat cincin di Selat Sunda telah mengalami tangkap lebih.<br /><br />Kata kunci: ikan pelagis, pukat cincin, laju eksploitasi, Selat Sunda

In order to look at changes in coral and reef fish communities during the period of 2006 to 2013, this research was carried out at Bunaken National Park (BNP) with 26 observation sites. The existing data and information of reef fish communities in the park generally could not be used as representative for describing the whole region. Percentage of coral cover and fish abundance during the study period shows that Bunaken Island is more similar to other locations. Reef fish community structure as seen from ecological index (H' at all sites being categorized, E category labile and low category C) shows the condition of the reef fish community is still good. Changes in the structure of reef fish communities showed declining conditions compared to 2006, and coral cover continued to decrease compared to 1998 and 2007. Good overall reef fish and coral cover have decreased; it is thought to be related to the pressure in BNP. Some of the pressures in the region were (i) increasing numbers of domestic as well as foreign visitors, (ii) increasing number of residents in the region, as well as the burden of waste and trash from the Bay of Manado. Penelitian dilakukan di Taman Nasional Bunaken (Utara dan Selatan)   pada 26 lokasi  pengamatan untuk menganalisis perubahan struktur komunitas ikan karang melalui kajian dari suatu time series data dari beberapa penelitian sebelumnya. Data primer mengenai ikan-ikan karang diperoleh melalui visual sensus bawah air yang bersamaan dengan observasi terumbu karang menggunakan point intercept transect. Nilai persentase tutupan karang dan kelimpahan ikan menunjukkan bahwa pada lokasi pengamatan Pulau Bunaken paling baik dibandingan lokasi lainnya. Struktur komunitas ikan karang yang dianalisis dengan indeks ekologi menunjukkan indeks keanekaragaman (H’) di semua site masuk kategori sedang, indeks kesamaan (E) kategori labil dan indeks Dominansi (C) kategori rendah. Hasil penelitian ini menunjukkan bahwa kondisi komunitas ikan karang masih baik, sekalipun  perubahan struktur komunitas ikan karang menunjukkan kondisi yang menurun dibandingkan tahun 2006, begitu juga tutupan karang yang terus turun dibandingkan tahun 1998 dan 2007. Secara keseluruhan baik ikan karang maupun tutupan karang mengalami penurunan, hal ini diduga terkait dengan tekanan yang dialami kawasan TN. Bunaken. Salah satu tekanan terhadap kawasan adalah jumlah turis dari dalam maupun luar negeri yang semakin meningkat tiap tahunnya, penambahan jumlah penduduk di dalam kawasan, serta beban limbah dan sampah dari Teluk Manado.

ABSTRACT Pump handline is a traditional fishing gear commonly used by fishermen in the Gulf Amurang to catch demersal fishes/reef fishes. This handline uses artificial baits made of fiber cloth of different colors, and an effective bait color is unknown yet. This research aims to study the effect of artificial bait colors on the pump handline catches, and to identify the species. This research was conducted through experimental methods by operating four pump handline units using red and yellow artificial baits starting at 07:00 am until 14:00 pm. The catches were 33 fishes, consisting of 23 fishes caught with red baits and 10 fishes caught with yellow baits. The results showed that red and yellow artificial baits on the pump handline had different number of catches, the average catches per hour of the respective bait colors were 3.83 (4 fishes) and 1.67 (2 fishes). The catch species consisted of 17 species, and was predominated by groupers, parrot fish, snappers and goat fish. Keywords: pump handline, artificial bait, demersal fish/reef fishes.   ABSTRAK Pancing pompa merupakan alat tangkap ikan tradisional yang umum dioperasikan oleh nelayan di Teluk Amurang untuk menangkap jenis-jenis ikan demersal/ikan-ikan karang. Umpan yang digunakan adalah umpan buatan dari serat kain yang warnanya bervariasi, dan warna umpan yang efektif belum diketahui. Sehingga tujuan penelitian ialah mempelajari pengaruh warna umpan buatan terhadap hasil tangkapan pancing pompa dan mengidentifikasi jenis-jenis ikan yang tertangkap. Penelitian ini dilakukan melalui metode eksperimental dengan mengoperasikan empat unit pancing pompa yang menggunakan umpan buatan warna merah dan kuning pada pukul 07.00 hingga pukul 14:00 Wita. Hasil tangkapan yang diperoleh berjumlah 33 ekor ikan, terdiri dari 23 ekor tertangkap dengan umpan buatan warna merah dan 10 ekor tertangkap dengan umpan buatan warna kuning. Hasil analisis menyimpulkan bahwa umpan buatan warna merah dan warna kuning pada pancing pompa ternyata berbeda, karena umpan warna merah mendapatkan hasil rata-rata 3,83 (4 ekor) per jam, sedangkan umpan warna kuning rata-rata 1,67 (2 ekor) per jam.
