Abstract

Wilayah Pengelolaan Perikanan Negara Republik Indonesia WPP-571 sesuai Permen KP mencakup perairan Laut Andaman dan Selat  Malaka. Perairan Selat Malaka merupakan perairan yang berbatasan langsung dengan batas wilayah maritim negara tetangga yaitu Malaysia. Perairan ini sebagai wilayah perairan yang cukup potensial sangat memungkinkan terjadinya praktek penangkapan ikan secara tidak sah. Dalam hal kegiatan pengawasan kapal perikanan yang ada WPP- 571, kepatuhan nelayan terhadap kegiatan aktivitas penangkapan ikan masih belum efektif atau masih belum maksimal dan ditambah lagi meningkatnya jumlah kapal perikanan yang beroperasi di WPP- 571. Informasi tentang pelanggaran kapal penangkapan ikan perlu di deskripsikan agar dapat menjadi informasi yang berguna untuk mengevaluasi kegiatan pengawasan kapal perikanan di WPP- 571.Tujuan dari penelitian ini adalah untuk mengetahui kesesuaian antara daerah operasi penangkapan ikan dengan izin operasi penangkapan ikan di WPP.menganalisis jenis pelanggaran yang terpantau di WPP-571 dan dan mengetahui partisipasi nelayan di PPS Belawan dalam mengurangi illegal fishing. Penelitian ini akan diawali dengan pengajuan surat hingga pada pengerjaan laporan penelitian. Rencana pengambilan data penelitian ini bertempat di Stasiun PSDKP Belawan dan PPS Belawan di Provinsi Sumatera Utara.

Abstract

Covid-19 brought their intensive effects in marine fishery subsector in Manado by the end of 2019. The research aimed at finding out how far the effect of purse seine fishery contribute on Gross Regional Domestic Product (GRDP) Manado between before and after Covid-19. Secondary data collected from of BPS Manado dan North Sulawesi in 2018 - 2022, while primary data i.e purse seiner’s catches and its value production from the annual reports of Tumumpa coastal fishing port by direct observation on board. Data was analyzed using Location Quotient (LQ) approach. The result of data analysis showed, there was a declining production during Covid-19 due to a lack of fishing operation activities, having a consequence in fish production value decreasing, because the fish distribution obstruction from the centres of producer to the centres of consumer. Before Covid-19 period, it gained the average catches of 10,7 million tons.yrs-1 (increasing 17,46% yrs-1), with production value of Rp. 159,6 billion yrs-1 (increase 23,23% yrs-1). During Covid-19, average cathes of purse seiner was 11,3 billion tons yrs-1 (decline 8,25% yrs-1) and production value of Rp. 204,3 billion yrs-1 in average (decline of 8,30% yrs-1). Purse seine fishery contribution on GRDP Manado decrease from 0,10% yrs-1 before Covid-19 (2017-2019) to - 0.42% yrs-1 during Covid-19 (2020-2012). During these two periods, (marine) fishery subsector had a LQ < 1, meant that this subsector was really not a basis of the subsector. To fulfill the Manado society consumption on fishes, it is required to supply fishes from other locations. The other side, the business of purse seiner fishery brought an agreeable advantage.

Abstract

Bigeye scad (Selar crumenophthalmus Bloch 1793) is rich source of proteins, Omega-3 fatty acids, and various important vitamins and minerals for human body, that makes the fish has an important economic value. Additionally, because of forming an important shoal on coastal seawaters, the fish is frequently captured, notably by purseseiners in an important quantity from the FMA 716 of North Sulawesi seawaters. The intensiveness captures of the fish may affect the sustainability and continuity life of the species. The research aims at analyzing some biological reproduction aspects of species based on gender and fishing season. The 400 samples, 200 tails on May and 200 tails on August 2022, have selected by a purposive random sampling from the captures. Data analisys refers to some common formulas, such as the length and weight size structure, sex and weight ratio, W-L relationship (W = aLb, W = weight, g), L = length (cmFL), a and b constants, condition factor (K), length at first capture (Lc50%). The legal size is determined by comparing the length at first capture (Lc50%) observed and at first maturity (Lm50%) reference. On May, the sample weight is 33,439 g (51.8% of 400 samples), the sex and weight ratios are 1:1.08 and 1:1.36 respectively with the conversion factor (cf) of 1.26. The average length and weight sizes are 21.62 ± 0.17 cm and 167.20 ± 5.15 g respectively, where the average weight per 1 cmFL is 7.67 ± 0.18 g. The L-W relationship follows W = 0.1492 L 3.0785 (r = 0.86) for male, W = 0.0566 L 3.8088 (r = 0.90) for female, and W = 0.0864 L 3.4940 (r = 0.91) for all, with K average of 1.60 ± 0.02 for male, 1.66 ± 0.03 for female, and 1.63 ± 0.02 for 200 samples. On August, the sample weight is 31,115 g (48.2% of 400 samples), the sex and weight ratios are 1:1.50 and 1:1.82 respectively, with cf of 1.21. The average length and weight sizes are 21.49 ± 0.16 cm and 155.58 ± 4.71 g respectively, where the average weight per 1 cmFL is 7.19 ± 0.17 g. The L-W relationship follows W = 0.1515 L 3.047 (r = 0.88) for male, W = 0.0789 L 3.5485 (r = 0.88) for female, and W = 0.0836 L 3.5023 (r = 0.90) for all samples, with K average of 1.50 ± 0.02 for male, 1.58 ± 0.03for female, and K of 1.55 ± 0.02 for 200 samples. On both fishing seasons, all captures are categorized a positive allometry (b>3) and 96.75% of captures has a legal size. All females have passed their first maturity stage. For this reason, the fishermen must consider carefully when they catch the fishes, outside of the two months. Considering the intensiveness of fishing activities to such species, it is indispensable since early for all stakeholders designing a regulation to limitate captutes by gender size and fishing seasons, for all species of high potential and economic value of high density of shoals.
