Abstract

Abstract. The Arafura waters are rich in fishery resources such as shrimp, demersal fish, pelagic fish, and crustaceans. The Tenggiri fish (Scomberomorus commerson) is the mainstay of pelagic fisheries and is dominant landed in 2 (two) locations in Poumako (Mimika) and Dobo (Aru Islands). The number of samples measured during the study was 2,645 species derived from the waters of Arafura. The production of fisheries increased to be an indication that it is necessary to manage the intensive utilization of fish resources to keep the population. Management requires basic scientific study of biological aspects and population dynamics of Narrow-bareed mackerel. The study was conducted from March to December 2017 in Poumako and Dobo. The 35-130 cmFL fish size structure is dominant at a size of 95 cmFL with negative allometric growth. The length at the first catch is 78 cmFL with a growth rate of (K) = 0.86 per year and an infinitive length (L?) = 136.5 cmFL. Fish were first to catch at the age of 10 months, and the age reached infinitive (L?) is 9.5 years old. The recruitment of the fish from August (11.82%) up to October (18.13%) with a peak of September at 23.75%. The fishing mortality (F) is higher than that of natural mortality (M) so that the exploitation rate (F) = 0.67, which indicates that overfishing has occurred in this area. One form of fisheries management that can be done is to limit the fishing season to provide the opportunity of fish to reproduce and recruitment to restore the population.Keywords: Biological aspects, dynamic population, Scomberomorus commerson, Arafura, Poumako, Dobo Abstrak. Perairan Arafura kaya akan sumberdaya perikanan baik udang, ikan demersal, ikan pelagis dan krustasea. Ikan tenggiri (Scomberomorus commerson) menjadi andalan perikanan pelagis dari perairan ini dan dominan didaratkan pada dua lokasi yaitu di Poumako (Mimika) dan Dobo (Kepulauan Aru). Jumlah sampel yang diukur selama penelitian adalah 2.645 ekor ikan tenggiri. Adapun tujuan dari kajian ini untuk perencanaan pengelolaan terhadap pemanfaatan ikan tenggiri yang semakin pasif dieksploitasi sehingga populasinya tetap terjaga. Oleh karena itu pengelolaan ini memerlukan dasar kajian ilmiah berupa aspek biologi dan dinamika populasi ikan tersebut. Penelitian ini dilakukan dari Maret hingga Desember 2017 di Poumako dan Dobo. Hasil analisis distribusi panjang ikan menunjukkan nilai antara 35-130 cmFL, dimana dominan yang tertangkap pada ukuran 95 cmFL dengan pola pertumbuhan allometrik negatif. Ukuran pertama kali ikan tertangkap adalah 78 cmFL dengan laju pertumbuhan (K) = 0,86 per tahun dan panjang infinitif (L?) = 136,5 cmFL. Ikan pertama kali tertangkap diestimasikan pada usia 10 bulan dan umur saat mencapai panjang infinitif (L?) adalah 9,5 tahun. Rekruitmen ikan ini diestimasikan berlangsung pada Agustus (11,82%) hingga Oktober (18,13%) dengan puncak rekruitmen terjadi pada bulan September sebesar 23,75%. Nilai kematian akibat penangkapan (F) lebih tinggi dibandingkan dengan kematian alamiah (M) sehingga tingkat pemanfaatannya (F) = 0,67 yang artinya ikan sudah mengalami overfishing. Salah satu bentuk pengelolaan perikanan ikan tenggiri yang dapat dilakukan adalah dengan membatasi musim penangkapan agar memberikan kesempatan ikan melakukan reproduksi dan rekruitmen di perairan sehingga dapat memulihkan populasi.Kata kunci: Aspek biologi, dinamika populasi, Scomberomorus commerson, Arafura, Poumako, Dobo

Abstract

AbstrakPenangkapan ikan di perairan Arafura banyak dilakukan oleh nelayan dari Pulau Jawa diantaranya Jakarta, Probolinggo, Pati, dan Indramayu. Nelayan dari Probolinggo yang menangkap ikan di perairan Arafura (WPP 718) menggunakan alat tangkap jaring dan pancing rawai dengan tujuan utama adalah ikan demersal, yaitu kakap (Lutjanus spp.), kerapu (Epeniphelus spp.), lencam (Lethrinus lentjan.), dan lainnya. Pemanfaatan ikan demersal terutama ikan lencam (Lethrinus lentjan) yang terus-menerus akan memicu terjadinya perubahan stok populasi ikan di perairan, sehingga diperlukan analisa ilmiah sebagai dasar pengelolaan perikanan. Tujuan dari analisa ilmiah ini untuk menjadi nilai kontrol dalam pengawasan jumlah eksploitasi ikan dan bahan pengkajian stok ikan lencam (Lethrinus lentjan). Penelitian dilakukan Februari hingga Desember 2017 di TPI Mayangan Probolinggo. Struktur ukuran ikan 23?65 cmFL dengan dominan pada ukuran 50 cmFL dengan ukuran pertama kali tertangkap (Lc) 44,5 cmFL. Laju pertumbuhan (K) 0,32 per tahun dengan panjang asimtotik 74 cmFL. Tingkat kematian karena penangkapan (F) lebih tinggi daripada tingkat kematian alami (M) dan tingkat eksploitasi E = 0,57%, yang berarti telah terjadi overfishing. Pengurangan eksploitasi sebesar 14%, dan penetapan ukuran layak tangkap serta ukuran legal diperdagangkan dapat menjadi upaya dalam dalam menjaga populasi ikan lencam.Abstract Fishing in Arafura waters is mostly done by fishermen from Java, including Jakarta, Probolinggo, Pati, and Indramayu. Fishermen from Probolinggo who catch fish in Arafura waters (FMA 718) use fishing nets and longline fishing with the main purpose being demersal fish, namely snapper (Lutjanus spp.), Groupers (Epeniphelus spp.), Lencam (Lethrinus lentjan) and others. Exploitation of demersal fish, especially lencam fish (Lethrinus lentjan) which will continually trigger changes in fish population stock in waters, so the scientific analysis is needed as a basis for fisheries management. The purpose of this scientific analysis is to become a control value in monitoring the amount of fish exploitation for fish stock assessment  (Lethrinus lentjan). The study was conducted from February to December 2017 at TPI Mayangan Probolinggo. The size structure of fish 23?65 cmFL with a dominant size of 50 cmFL with the length at first capture (Lc) 44.5 cmFL. Growth rate (K) 0.32 per year with an asymptotic length of 74 cmFL. The fishing mortality (F) is higher than the natural mortality (M) and the exploitation level E = 0.57%, which means overfishing has occurred. The 14% reduction in exploitation and the determination of catch size and legal size of trade can be an effort in maintaining fish populations.

Abstract

Pelagic fish are spesies that live in water column at depth of 100 to 200 meters from surface. They migrate as a group looking for nutrient and spawning place. Potential fisheries comodities in Indonesia including pelagic fish have high economic value. Then, stock assessment of pelagic fish measurement is important to researched. The research was conducted in May – June 2016 surrounding South China Sea waters using Madidihang 02 Research Vessel operated by Marine Fisheries Affair (MFA) Republic of Indonesia. To estimate the density of pelagic fish hydro-accoustic equipment and oceanography parameters were used and measured during the campaign. The split beam echosounder was use in aim to obtain precission position and number of fish target. The highest density of fish was found around Tambelan Island and Anambas Island. Statistically pelagic fish density has correlation with chlorophyll-a, salinity, temperature, and sea current velocity. The statistical analysis between pelagic fish density and those oceanography parameters (as statistic variables) yields positive vector correlation.

Abstract

Status stok merupakan salah satu dasar utama dalam merumuskan pengelolaan sumber daya ikan yang berkelanjutan di WPP NRI. Tulisan ini bertujuan untuk mengevaluasi status stok sumber daya ikan di WPP NRI dan alternatf pengelolaannya. Penelitian dilaksanakan pada tahun 2015-2016 dengan menggunakan metode holistik dan analitik. Hasil analisis menunjukkan potensi sumber daya ikan di perairan Indonesia (WPP NRI) adalah sebesar 12,54 juta ton per tahun dengan potensi tertinggi sebagai ikan pelagis kecil sebesar 4,88 juta ton/tahun (39 %) dan yang terendah adalah lobster sebesar 11.159 ton (1 %). Berdasarkan WPP NRI, potensi sumber daya ikan tertinggi sebesar 2,64 juta ton (21 %) terdapat di WPP NRI 718 (Laut Aru dan Laut Arafura) dan yang terendah sebesar 425.444 ton di perairan WPP NRI 571 (Selat Malaka dan Laut Andaman). Tingkat pemanfaatan ikan di WPP NRI secara keseluruhan didominasi status fully-exploited (indikator warna kuning) sekitar 44 %, diikuti status overfishing (indikator warna merah) sekitar 38% serta status moderat sekitar 18 %. Agar sumber daya ikan di perairan WPP NRI berada dalam tahapan yang berkelanjutan, maka harus dilakukan penataan upaya penangkapan dengan mengurangi jumlah upaya penangkapan sesuai acuan upaya optimal (f.opt) pada WPP yang mengalami kondisi overfishing dan meningkatkan upaya di WPP yang tingkat pemanfaatannya masih moderat dan fully-exploited. Stock status of fish resources were a basis advices to define an apropriate fisheries management towards sustainable fish resource. The purpose of this study was to evaluate the stock status of fish resources and its management alternative in FMAs. The study was conducted from 2015 to 2016 using a holistic and analytic method. Estimation of all fish potency in Indonesia marine waters was 12.54 million tons/year which the highest potency was small pelagic fish group about 4.88 million tons/year (39 %) and the lowest potency was spiny lobster group about 11,159 tons/year (1 %). Based on the FMAs, the highest potency was about 2.64 million tons/year (21 %) in FMA 718 (Aru sea and Arafura sea) and the lowest potency was about 425,444 tons/year (3 %) found in FMA 571 (Malacca strait and Andaman sea). Most of fish resources was in the condition of fully-exploited (44 % yellow color) followed by overfishing (34 % red color) and moderate (21 % green color). Fish groups which included in the highest overfishing by FMAs were squid group. Management alternatives in those prespective are suggested to decrease the fishing effort at the level of f.opt (fishing optimum) by fish groups on the FMAs experiencing overfishing accordingly and to increase an effort at the level of f opt for fish groups on the FMAs in the fully exploited and moderate condition

Abstract

Bigeye tuna is an important fish resource in the Indian Ocean. This species like other tuna species needs to be managed properly in both national and international levels. Therefore some data and information on population structure and bioreproduction are required for management purpose. The current research was conducted to identify the population structure and bioreproduction of bigeye tuna (Thunnus obesus) in west off Sumatera and south off Java and Nusa Tenggara of Indian Ocean where tuna fishing spots are important. This research was based on catch landed by fishermen from the Indian Ocean during 2010. Analysis of population structure was done using DNA genetic analyses and bioreproduction by using histology technique. Results show that the population structure of the bigeye tuna in the Indian Ocean consisted of two different sub populations namely sub population of west off Sumatra and sub population of south of Java and Nusa Tenggara waters. Most of catch (about 39%) was categorized as immature fish (GI I). The immature fish was mostly found in west off Sumatera waters, meanwhile the catch in south off Java and Nusa Tenggara waters was mostly categorized as mature fish. This result may indicate that south off Java and Nusa Tenggara waters is a spawning ground of the bigeye tuna.

Abstract

Scientific advices on population dynamic of banana prawn (P. merguiensis de Man) are required as an input to support an apropriate fisheries management. This study aims to identify the population parameters of the banana prawn in Tanah Laut waters. The study was conducted in Tanah Laut based on monthly enumeration data (January to November 2016). Results has been shown that the length size of carapace at first maturity of banana prawn was 43.39 mm. Sex ratio of males and females was 1 : 0.8. The chi square test indicated that comparison of male and female of the banana prawn was significantly different. It means that there was not balance in number between males and females. The spawning season of banana prawn in Tanah Laut waters happened throughout year and reached the peak on November (south-east monsoon). The growth parameter of banana prawn was 1.05/year with maximum carapace length (Loo) of 55.0 mm. Instantaneous total mortality (Z) and natural mortality (M) were 6.05/year and 1.58/year, respectively. While fishing mortality (F) and exploitation rate (E) respectively were 4.47/year and 0.74/year respectively. The exploitation rate of banana prawn in Tanah Laut waters was high. Therefore, fishing effort of the banana prawn in that waters should be reduced to about 48 % for next coming year.
