Full textAbstract:
Objetivo: Identificar se há dificuldade no diagnóstico da patologia em razão das variadas manifestações clínicas e definir se há uma causa mais prevalente. Método: O estudo consiste em uma Revisão Integrativa de literatura, em que foram selecionados artigos das bases de dados: SciELO e MEDLINE, utilizando como critérios de inclusão artigos em português, inglês e francês, publicados entre 1922-2012; que abordassem o viés etiopatogênico da pelagra; e com qualquer delineamento metodológico. Foram utilizados os descritores: “pelagra”, “niacina” e “manifestações clínicas''. A amostra final foi constituída de 6 artigos. Resultados: Observou-se nos artigos que compõem a amostra que uma porcentagem alta de pacientes apresentam a “Pelagra Sine Pelagra”, ou seja, sem a manifestação das lesões dermatológicas características da pelagra, observando-se desse modo somente os distúrbios gastrointestinais e/ou neurológicos, dificultando o diagnóstico da patologia. No tocante à causa prevalente, é possível definir o alcoolismo como o fator de risco principal para o surgimento da doença. Conclusão: Concluiu-se que o perfil mais relatado foi o de indivíduos oligossintomáticos, em especial pacientes que apresentam quadros de “Pelagra Sine Pelagra”. A doença inicia-se com desordens dos órgãos digestivos, seguido do surgimento de lesões cutâneas, e, por fim, alterações nervosas. Em decorrência desse quadro arrastado e de nem sempre ser possível identificar a tríade clássica nos pacientes, tem-se um empecilho no diagnóstico tanto precoce quanto a longo prazo. Ademais, identificou-se alguns fatores de risco para a patologia, como alcoolismo, fator sazonal, radiação solar e desnutrição, sendo o alcoolismo a maior causa de pelagra na atualidade.

El 15 de marzo de 2019 el ciclón Idai golpeó intensamente a varios países el sudeste de África, entre ellos, Mozambique. Una de sus provincias más afectada fue Sofala y Médicos del Mundo España (MdM) respondió a la emergencia instalando centros de salud temporales en el distrito de Nhamatanda (provincia de Sofala), para atender las necesidades sanitarias básicas de la población afectada. En el mes de mayo de 2019 se detectó el primer caso de pelagra en un centro operado por MdM, al que siguieron otros muchos en las siguientes semanas. Esto provocó la necesidad de ofrecer una respuesta coordinada. MdM aunó esfuerzos con las autoridades sanitarias, así como con diferentes actores locales e internacionales en la articulación de un plan estratégico basado en la detección de casos, diagnóstico, tratamiento y prevención de la pelagra. En este artículo se describe la experiencia de MdM durante las ocho semanas en las que se detectaron y trataron los casos de pelagra.

Full textAbstract:
Pelagra es el nombre que se le ha dado a la condición poco conocida, resultado del déficit de vitamina B3 o niacina, una enfermedad potencialmente mortal la cual es caracterizada por una triada clásica de diarrea, dermatitis y delirio, que está asociada a factores de riesgo como desnutrición, pobreza, ingesta de ciertos medicamentos, alteraciones metabólicas entre otros. Pelagra es una enfermedad de diagnóstico clínico que difícilmente se considera en los diagnósticos diferenciales de pacientes que consultan en servicios de emergencias o que se encuentran internados en salones de hospitales y es de suma importancia debido a la mortalidad que conlleva un diagnóstico tardío.

Nelayan penangkap ikan yang efektif membutuhkan informasi sumberdaya ikan dan pola penyebarannya. Penelitian ini bertujuan untuk mengetahui pola sebaran sumber daya ikan yang dikaitkan dengan kondisi oseanografi WPP-NRI 715. Analisis dilakukan berdasarkan kombinasi metode hidroakustik dan profiling CTD pada stasiun oseanografi yang dirancang secara parallel pada jarak tertentu di lintasan tersebut. Hasil penelitian menunjukkan, estimasi ukuran ikan pelagis yang terdeteksi didominasi oleh ukuran kecil. Ikan pelagis kecil yang terdeteksi didominasi ukuran ikan antara 12-14 cm dan ikan pelagis besar ukuran ikan 28-31 cm. Kepadatan ikan pelagis kecil cenderung menurun dengan rerata faktor 0,4 dengan bertambahnya kedalaman, sebaliknya meningkat dengan rerata faktor 1,7 untuk ikan pelagis besar. Pada saat observasi, dikawasan perairan Laut Maluku bagian timur diindikasikan terjadinya upwelling ditandai dengan suhu rendah, salinitas tinggi, dan klorofil tinggi. Ikan pelagis besar lebih banyak ditemukan pada lokasi yang memiliki karakteristik suhu dan DO yang relatif lebih tinggi sedangkan salinitas lebih rendah dibandingkan dengan lapisan air yang didominasi ikan pelagis kecil. Informasi pola sebaran ikan pelagis ini diharapkan dapat dijadikan rujukan bagi pelaku perikanan tangkap dan masukan untuk bahan perumusan kebijakan pengelolaan perikanan tangkap yang berkelanjutan.Effective commercial fishers need information on fish resources and their distribution pattern. This study aims to determine distribution of fish resources in Indonesian FMA 715 through tracking hydroacoustic method and CTD profiling at stations within regular distances. The results showed that the estimated size of pelagic fish was dominated by small size fish groups. Small pelagic fish were detected at the size ranged between 12-14 cm and large pelagic fish was dominated by the size of 28-31cm. The density of small pelagic fish decreases with depth with average factor of 0.4, while the large pelagic fish with average factor of 1.7. An indicated upwelling incidence was likely occurred in the eastern part of Mollucas sea region, which were characterized by the low temperature, high salinity and high chlorophyll concentrations. Large pelagic fish were more occasionally found in locations with relatively higher temperature, DO characteristics and lower salinity compared with small pelagic fish. Information on the distribution pattern of pelagic fish is expected to be used as a reference for capture fishermen and inputs in formulating the policy the sustainable fisheries management.

Full textAbstract:
The marine area of Tojo Una-Una District has the potential for fishery resources and small islands resources which are used for fishery activities and marine ecotourism. Although most of its territorial waters are a conservation area of the Togean Islands National Park (TINP), in the utilization of fish resources in this area, some still use destructive tools that threaten the habitat and preserve of pelagic fish resources and the economic sustainability of local communities. This study aims to estimate the maximum economic potential of the catch and the level of utilization of pelagic fish resources in Tojo Una-Una district’s sea waters. The research data used combines time-series data from pelagic fish catches and fishing effort (trips) from 2003 to 2015, field survey data, and analyzed using the Gordon-Schaefer Bioeconomic Model approach or the Surplus Production Model. The estimation results show that the total maximum economic Yield (MEY) of pelagic fish resources in the waters of Tojo Una-Una District is quite large, namely 14,950.54 tons per year. Although the potential level of economic utilization of large pelagic fish resources is higher than the use of small pelagic fish, the potential economic rent obtained from the use of small pelagic fish is still higher than that of large pelagic fish. Given that the utilization of pelagic fish resources in the waters of Tojo Una-Una District is under MEY, a careful addition to the capacity of the fishing effort is needed to increase the economic benefits of fish resources for fishermen and the region.Keywords:Estimation,Maximum Economic Yield Pelagic FishABSTRAKWilayah perairan laut Kabupaten Tojo Una-Una memiliki potensi sumberdaya perikanan dan sumberdaya pulau-pulau kecil yang dimanfaatkan untuk kegiatan perikanan dan ekowisata bahari. Wilayah perairan Kabupaten Tojo Una-Una sebagian besar merupakan kawasan konservasi Taman Nasional Kepulauan Togean (TNKT), namun dalam pemanfaatan sumberdaya ikan di wilayah ini masih ada yang menggunakan alat yang sifatnya destruktif sehingga mengancam habitat, kelestarian sumberdaya ikan pelagis dan keberlanjutan ekonomi masyarakat lokal. Penelitian ini bertujuan untuk mengestimasi potensi ekonomi maksimum hasil tangkapan dan tingkat pemanfaatan sumberdaya ikan pelagis di perairan laut kabupaten Tojo Una-Una. Analisis data dilakukan dengan menggabungkan data time-series hasil tangkapan ikan pelagis dan upaya tangkap (trip) dari tahun 2003 hingga 2015. Data survei lapangan dianalisis dengan menggunakan pendekatan Model Bioekonomi Gordon-Schaefer atau Model Produksi Surplus. Hasil analisis menunjukkan bahwa total tangkapan maksimum ekonomi (MEY) sumberdaya ikan pelagis di perairan Kabupaten Tojo Una-Una mencapai 14.950,54 ton per tahun. Namun demikian, potensi tingkat pemanfaatan secara ekonomi sumberdaya ikan pelagis besar lebih tinggi dibanding pemanfaatan ikan pelagis kecil, meskipun potensi rente ekonomi yang diperoleh dari pemanfaatan ikan pelagis kecil masih lebih tinggi dibanding ikan pelagis besar. Kesimpulannya, pemanfaatan sumberdaya ikan pelagis di wilayah perairan Kabupaten Tojo Una-Una berada di bawah MEY, maka penambahan secara hati-hati kapasitas upaya tangkap diperlukan untuk meningkatkan manfaat ekonomi sumberdaya ikan bagi nelayan dan daerah.Kata kunci:Estimasi, Hasil ekonomi maksimum,Ikan Pelagis

Foi feito diagnóstico clínico e laboratorial de cirosse hepática em 32 pacientes, de pancreatite crônica em 13 e de outras doenças (pelagra, desnutrição, neurite periférica e hepatite alcoólica) em 50. Pacientes com apenas sintomas psiquiátricos não foram estudadas. A obtenção das informações ocorreu após alguns dias de tratamento. Em média a idade em que começaram a ter sinais e sintomas das doenças que motivaram a procura de hospital para tratamento foi de 35,30 ± 7,72 anos na pancreatite crônica, 36,53 ± 8,39 anos na cirrose hepática e de 33,90 ± 11,27 anos nas outras doenças. O tempo de ingestão da bebida foi de 15,92 ± 7,15 anos na pancreatite crônica, 14,62 ± 8,70 anos na cirrose hepática e 13,24 ± 9,58 anos nas outras doenças. Antecedentes familiares de alcoolismo estiveram presentes em 64,2% dos casos, geralmente marido ou companheiro. Nenhuma delas tinha outras mulheres na família com problemas de alcoolismo. A média do tempo de alcoolismo para o aparecimento de cirrose hepática nas mulheres (14,62 anos) foi menor do que a encontrada para homens da mesma população (21,10 anos), estudados em trabalhos anteriores.

Klorofil-a banyak ditemukan pada fitoplankton dan menjadi indikator kesuburan perairan. Keberadaan fitoplankton ditandai dengan kandungan klorofil-a yang tinggi dan diikuti oleh keberadaan zooplankton yang akhirnya mempengaruhi keberadaan organisme perairan lainnya seperti ikan pelagis kecil maupun ikan pelagis besar sebagai suatu rantai makanan. Interaksi antara konsentrasi klorofil-a terhadap keberadaan dan konsentrasi ikan pelagis di Laut Jawa belum banyak diketahui. Penelitian ini dimaksudkan untuk mengetahui hubungan interaksi antara klorofil-a terhadap konsentrasi ikan pelagis. Penelitian dilakukan dengan mengumpulkan data runtun waktu hasil tangkapan beberapa jenis pelagis besar dan kecil yang didaratkan di PPI Pekalongan tahun 2007-2011 serta data runtun waktu konsentrasi klorofil-a dari perairan utara Jawa yang diperoleh dari informasi sekunder.Metode analisis korelasi linear sederhana (bivariate correlation) digunakan untukmengetahui ada atau tidaknya pengaruh antar variabel klorofil-a dan konsentrasi ikan pelagis. Hasil penelitian menunjukkan bahwa ikan layang (Decapterus russelli) paling nyata mendapat pengaruh dari konsentrasi klorofil-a (P<0,05) dan berkorelasi positif terhadap konsentrasi klorofil-a dengan nilai koefisien korelasi ( r ) sebesar 0,56, sedangkan ikan pelagis lainnya berkorelasi negatif. Ikan tongkol (Euthynnus affinis) posisinya menempati rantai makanan paling tinggi sebagai pemangsa, mempunyai korelasi positif (r = 0,5) terhadap Rastrelliger kanagurta dan r = 0,56 terhadap Amblygaster sirm.Chlorophyll-a is a light-absorbing pigment that can be found in photosynthetic organisms such as algae and phytoplankton. The evidence of phytoplankton that indicated by high contents of chlorophyll-a may followed the evidence of zooplankton and other micro aquatic organism as a food chain component. An overview of interrelationships between chlorophyll-a and pelagic fishes in the waters around Java Sea have not much investigated. The research was attempted to study the interaction between chlorophyll-a abundance and the abundance of small and large pelagic as well as relationship among small and large pelagic as prey-predators component. Research conducted by collecting time series catch data of small and large pelagic species landed at PPI Pekalongan during the period of 2006-2012, as well as the data of chlorophyll-a abundance through previous research studies. The results showed that layang (Decapterus russelli) was the most significant species that positively correlated to abundance of chlorophyll-a (P < 0.05) with value of r = 0.6. while others pelagic species have negative correlation. As a predator species, tongkol (Euthynnus affinis) was positively correlated ( r = 0.5) to the abundance of banyar (Rastrelliger kanagurta) as well as juwi (Amblygaster sirm) with r value 0.56.

Full textAbstract:
Most freshwater fishes have short pelagic early life stages. Lake Michigan presents an interesting scenario for yellow perch (Perca flavescens), a species with a long pelagic larval stage that may not be well adapted to lakes with an expansive pelagic environment and extensive offshore transport. We investigated the possibility that early life stages of yellow perch were transported well offshore from their nearshore spawning grounds and explored whether food resources were more or less favorable offshore. To determine the extent to which pelagic age-0 yellow perch moved offshore, we sampled at multiple scales ranging from local (<2 km) to across the lake (>120 km). Evidence of offshore movement by fish larvae occurred at each scale. Yellow perch larvae were quickly transported offshore from nearshore spawning sites and remained in the offshore pelagia to sizes of at least 30 mm. Zooplankton density was greater offshore than nearshore, suggesting that pelagic age-0 yellow perch find improved food resources offshore compared with their nearshore spawning sites. Currents operating at oceanographic scales likely influenced the offshore movement of pelagic age-0 yellow perch in Lake Michigan. These currents, coupled with prey availability for pelagic age-0 individuals, may influence the recruitment success of this species.

We estimated the seston elemental composition (C, N, P) and its ratio in pelagic and littoral zones of mesotrophic shallow Lake Obsterno during two contrasting seasons, as well as the influence of macrophyte beds on the seston stoichiometry. In the both pelagial and littoral zones in summer the C: N ratio was small, 4.62 and 7.05 respectively. But it increased slightly during autumn to 5.66 in pelagic samples against 8.33 in littoral ones. The large N : P ratio and the small phosphorus content specially in the macrophyte covered littoral zone equal to 57.7 in July against 22.47 in September suggest a high level of phosphorus limitation in the littoral locations as a possible mediated reason suppressing zooplankton abundance in sumabundance in sum in summer. Our results in the both pelagial and littoral habitat showed a highly P limited situation in which the N : P ratio was larger in littoral with macrophyte than in pelagial zones. The obtained data of littoral seston stoichiometry were recorded for the first time and exceeded the classical Redfield ratio. The elemental imbalance between macrophyte covered littoral and pelagial suggest that nutrients, especially P, are more limiting in macrophyte beds in summer due to the resource competition between phytoplankton and macrophytes for nutrients, a poor food quality, low zooplankton abundance, as well as its poor taxon-specific elemental ratio in summer.

Pemanfaatan sumber daya ikan pelagis kecil di Laut Cina Selatan wilayah Indonesia (luasnya sekitar 595.000 km2), khususnya di perairan pantai Kalimantan Barat dengan sasaran utamanya ikan kembung (Rastrelliger brachyosoma) pada tahun 1991 telah mencapai 94% dari rata-rata hasil tangkapan maksimum lestari. Perkembangan penangkapan ikan pelagis kecil ke arah lepas pantai yang dirintis oleh armada pukat cincin Pekalongan sejak tahun 1985 di perairan Pejantan telah diikuti oleh nelayan Kalimantan Barat, khususnya di Pemangkat pada tahun 1990. Jumlah kapal pukat cincin Pemangkat yang pada tahun 1995 hanya enam unit, pada tiap tahunnya meningkat sampai mencapai 48 unit pada tahun 2003. Penelitian ini bertujuan untuk memperoleh gambaran perikanan pelagis kecil yang berbasis di Pemangkat dengan alat tangkap pukat cincin. Analisis dilakukan berdasarkan pada data log book tiap trip kapal pukat cincin pada periode tahun 2004 - 2006. Hasil tangkapan pukat cincin didominansi oleh ikan pelagis kecil, terutama 2 jenis ikan layang (Decapterus russelli dan D. macrosoma), bentong (Selar crumenophthalmus), banyar (Rastrelliger kanagurta), dan tembang (Sardinella gibbosa), serta jenis-jenis ikan lainnya yang bernilai ekonomis. Hasil tangkapan ikan pelagis kecil bervariasi menurut musim, yaitu paling tinggi pada musim peralihan 1 dan peralihan 2, serta paling rendah pada musim barat. Catch per unit of effort jenis-jenis ikan pelagis kecil dari tahun 2005 - 2006 pada umumnya cenderung turun, diduga akibat tingginya jumlah upaya dari banyak armada pukat cincin lain, baik dari wilayah Indonesia maupun dari luar negeri. Exploitation of small pelagic fish resources in the South China Sea of Indonesian region (around 595,000 km2) especially in the coastal waters ofWest Kalimantan Province which short bodied mackerel (Rastrelliger brachyosoma) as the main target had reached at a rate of 94% of the average of maximum sustainable yield. The development of fishing on small pelagic fishes toward off shore pioneered by purse seine fleet of Pekalongan (north coast of Java) since 1985 then followed by fishermen of West Kalimantan, especially in Pemangkat in 1990. The number of purse seine of Pemangkat that only 6 units in 1995 increased every year up to 43 units in 2003. The aim of this research was to describe small pelagis fishery in the Pemangkat landing site by purse seine. Analysis was conducted based on log book data of purse seiners during the period of 2004 to 2006. During the period of 2004 to 2006, the catch of Pemangkat purse seine was mostly small pelagic fish mainly composed of 2 species of scads (Decapterus russelli and D. macrosoma), big eye scad (Selar crumenophthalmus), Indian mackerel (Rastrelliger kanagurta), and fringerscale sardine (Sardinella gibbosa), also the other economic fishes. Both the catch varied between moonson. The highest catch was during the two intermoonsons and the lowest catch was during the west moonson. Catch per unit of effort of the small pelagic fishes from 2005 to 2006 mainly decreased, since the high amount of the efforts from purse seine fleets of the other locations of Indonesia as well as foreign countries.

Penelitian dilakukan pada bulan Desember 2018 sampai dengan Agustus 2019 dan sampling pengambilan data di provinsi Sulawesi Utara dan DKI Jakarta. Hasil analisis menunjukkan bahwa produksi legal ikan pelagis besar pada maximum economic yield (MEY) adalah sebesar 368.522,25 ton per tahun dengan effort sebanyak 554 902 trip per tahun dan perolehan rente sebesar Rp3,06 trilyun/tahun sedangkan produksi total (legal dan IUU fishing) adalah sebesar 530.451,63 ton per tahun dengan effort sebanyak 929 414 trip per tahun dan rente sebesar Rp6,73 trilyun/tahun. IUU fishing menimbulkan dampak hilangnya potensi perolehan rente ekonomi pada pemanfaatan sumber daya ikan pelagis besar di WPPNRI 715 yaitu sebesar Rp3,66 trilyun/tahun. Hasil penelitian menyimpulkan bahwa IUU fishing merugikan perikanan tangkap pelagis besar di WPPNRI 715 sehingga diperlukan rumusan kebijakan dalam pengawasan sumberdaya kelautan dan perikanan berupa peningkatan kualitas sumberdaya manusia dalam bidang perikanan, penggunaan satelit pemantauan dan kebijakan peningkatan kesadaran dan penegakkan hukum di laut.Title: Economic Impact of IUU Fishing on Big Pelagic Fish in WPPNRI 715This research aims to determine the economic impact of IUU fishing large pelagic fish in WPPNRI 715. The research is a case study with multistage random sampling. Data were analysed with bioeconomics model for fisheries. The research was conducted from December 2018 to August 2019, and the sampling areas of data collection was in the provinces of North Sulawesi and DKI Jakarta. The results of the analysis showed that the legal production of large pelagic fish at maximum economic yield (MEY) is 368,522.25 tons per year with an effort of 554 902 trips per year, and economic rent at IDR3.06 trillions/year. The total production (legal and IUU fishing) is 530,451.63 tons per year with an effort of 929.414 trips per year and economic rent of IDR 6.73 trillions/year. IUU fishing has an impact on the loss of potential economic rent on the large pelagic fish resources in the WPPNRI 715 amounting to IDR 3.66 trillion/year. The results showed that IUU fishing has a detrimental economic impact on the large pelagic fish in WPPNRI 715. Therefore, a policy is necessary to increase supervision of marine and fishery resources by improving the quality of fishery human resources, the use of monitoring satellites and policies to increase awareness and law enforcement at sea.

Penelitian ini bertujuan untuk mempelajari distribusi spasial kepadatan ikan pelagis serta hubungan dengan kondisi perairan pada musim peralihan di perairan pantai utara Jawa bagian timur dan Laut Flores, berdasarkan pada pengambilan contoh akustik dan 34 stasiun oseanografi pada bulan Oktober 2005. Data target strength menunjukkan bahwa rata-rata ukuran ikan pelagis yang terdeteksi di perairan pantai utara Jawa bagian timur adalah 10 sampai dengan 56 cm. Ukuran ikan di daerah lepas pantai lebih kecil dibanding daerah dekat pantai. Pada musim peralihan, kondisi suhu dan salinitas perairan relatif homogen. Sehingga faktor tersebut kurang signifikan terhadap distribusi keberadaan ikan. Diduga faktor lingkungan lain seperti faktor biologi dan kimia, berperan dalam pola penyebaran ikan pelagis kecil di perairan ini. Di Laut Flores dan sekitar Pulau-Pulau Sunda, densitas ikan tertinggi pada stratum 10 sampai dengan 50 m dengan ukuran 10 sampai dengan 20 cm terutama di beberapa lahan marginal seperti sekitar selat dan kepulauan. Selain merupakan lapisan tercampur di mana kondisi suhu dan salinitas relatif stabil pada kedalaman 10 sampai dengan 50 m, lahan marginal merupakan daerah subur tempat pertemuan 2 massa air yang berbeda yang membentuk front diharapkan merupakan tempat berkumpul ikan. Lapisan termoklin yang bersifat lemah berada di bawah 50 m, hal ini mempengaruhi densitas ikan yang semakin rendah pada kedalaman lebih dari 50 m. Ikan pelagis yang berada pada lapisan termoklin mempunyai ukuran yang lebih besar yaitu 14 sampai dengan 40 cm. Pada musim yang sama, rata-rata kepadatan dan ukuran ikan pelagis kecil di wilayah timur lebih rendah daripada sebelah barat. The aim of this research is to study the distribution of spasial density of pelagic fish with waters condition at intermonsoon in north of Java coast waters part of east and Flores Sea, based on acoustic sampling and 34 oceanography stations in October 2005. The target strength of fish indicated that pelagic fish measure in north of Java coast waters part of east is about 10 to 56 cm. Fish sizes in offshore is smaller than near shore. At intermonsoon, the waters condition of temperature and salinity was homogeneous relatively. Therefore, that are less to distribution of fish density. Anticipated, the others environmental factor like chemical and biological, was influenced to distribution of small pelagic fish in this area. In Flores Sea and Sunda Islands, the highest of fish density at 10 to 50 m and fish sizes about 10 to 20 cm especially in some marginal areas near archipelago and strait. At 10 to 50 m is mixed layer, where temperature and salinity was relative stabilize, the maginal areas is fertility waters which is passage of the shifting by two different water masses and front were formed . The weak termocline was formed below 50 m, maked fish density are progressively lower below 50 m. The pelagic fish residing in termocline layers have larger ones measure than stratum 10 to 50 m is about 14 to 40 cm. On same season, the fish measure and density of small pelagic fishes in east region is lower than at westside.

Title: Minimalization Distribution Cost of Fisheries Product Processing Industry: The Application of Transportation in Program SolverSolution to distribution problem of a commodity or product is necessary in order to minimize its distribution cost. Program solver is one of the most widely used software to solve problem related to transportation. Transportation model determines distribution cost of a product from port of origin to port of destination. This research purpose is intending on analyzing the application of program solver in minimizing fish distribution cost from suppliers to industrial centers. The result showed that efficiency distribution cost of tuna was Rp. 757.983.424,- and the efficiency distribution cost of small pelagic fish was Rp. 268.012.767,-. Distribution cost of tuna from Bitung to Surabaya is more efficient, distribution cost of tuna from Ternate to Makassar is more efficient, distribution cost of tuna from Medan to Surabaya is more efficient, distribution cost of tuna from Banyuwangi to Jakarta is more efficient, and distribution cost of tuna from the other ports of origin are more efficient to Makassar, Jakarta, Surabaya and the other ports of destination. Distribution cost of small pelagic fish from Bitung to Makassar is more efficient, distribution cost of small pelagic fish from Ternate to Surabaya is more efficient, distribution cost of small pelagic fish from Medan to Makassar is more efficient, distribution cost of small pelagic fish from Banyuwangi to Makassar and Surabaya is more efficient, and distribution cost of small pelagic fish from the other ports of origin are more efficient to Jakarta and Surabaya. Therefore, fish distribution from port of origin should be focused to a particular destination port in order to get more efficient distribution cost and stable fish supply in the destination area.

Perikanan pelagis di perairan Selat Bali telah diusahakan sejak lama. Data runtut tahun hasil tangkapan yang didaratkan cenderung berfluktuasi. Kajian ini bertujuan untuk mengetahui kondisi spasial dan temporal karakteristik oseanografi, terkait dengan dengan dinamika perikanan pelagis di Selat Bali. Data parameter oseanografi meliputi suhu permukaan laut (SPL) dan klorofill-a (chl-a) yang diperoleh dari citra satelit penginderaan jauh Aqua/Terra MODIS, sedangkan data sumberdaya perikanan pelagis berupa hasil tangkapan/satuan upaya (Catch per Unit Effort, CPUE) ikan pelagis diperoleh dari Tempat Pendaratan Ikan (TPI) Pengambengan, Jembrana - Bali pada periode Januari 2007 hingga Desember 2015. Uji statistik regresi linear berganda digunakan untuk mengetahui pengaruh parameter oseanografi terhadap kondisi perubahan sumberdaya perikanan pelagis. Sebaran spasial SPL menunjukkan bahwa pada Mei hingga November suhu permukaan laut cenderung rendah serta tidak ada perbedaan yang signifikan antara suhu di perairan pantai dan di laut lepas. Secara temporal terlihat bahwa suhu terendah terjadi pada musim timur yaitu pada Agustus 2007. Sebaran spasial chl-a menunjukkan bahwa peningkatan konsentrasi chl-a dimulai dari Mei hingga Oktober serta terdapat perbedaan yang signifikan antara chl-a perairan pantai dan laut lepas. Secara temporal terlihat bahwa konsentrasi chl-a tertinggi terjadi pada Oktober 2015. Faktor iklim yang merupakan faktor eksternal memberikan pengaruh terhadap perubahan konsentrasi chl-a pada lokasi penelitian. Faktor iklim tersebut adalah kecepatan angin dan kejadian El-Nino. Hasil analisis statistik menunjukkan bahwa perubahan parameter SPL dan chl-a secara bersama-sama berpengaruh signifikan terhadap perubahan CPUE ikan pelagis, namun secara parsial parameter chl-a memberikan pengaruh yang lebih signifikan dibandingkan dengan parameter SPL.Pelagic fisheries around Bali Strait have been exploited since decades. Based on monthly and annual landing data, fish production around Bali strait are very fluctuated. This study aims to determine the spatial and temporal conditions of oceanographic characteristics and how they relate to the dynamics of pelagic fisheries in the Bali Strait. The oceanographic parameter data consist of sea surface temperature (SST) and chlorophyll-a (chl-a) that obtained from Aqua / Terra MODIS remote sensing satellite imagery, while the dynamics of pelagic fish resource data indicated by Catch per Unit Effort (CPUE) derrived from landing place (TPI) Pengambengan, Jembrana - Bali in the period January 2007 to December 2015. Multiple linear regression analysis were applied to determine the effect of oceanographic parameters on the changing conditions of pelagic fishery resources. Spatial distribution of SPL indicates that in May to November sea surface temperature tends to be low and there is no significant difference between the temperature in coastal waters and on high seas. The temporal distribution shows that the lowest temperature occurred during the southeast monsoon in August 2007. The spatial distribution of chl-a showed that the chl-a concentration starts to increase from May to October and there were significant differences between chl-a coastal waters and high seas. The temporal distribution shows that the highest chl-a concentration occurred in October 2015. Climate factor which is an external factor has an effect on the change of chl-a concentration at the research location. Climatic factors are wind speed and El-Nino events. The result of the statistical analysis shows that the change of SPL and chl-a parameters together significantly influence on the CPUE of pelagic fish, but partially chl-a parameter gives highly significant effect than SST parameter.

Full textAbstract:
The Burgess Shale-type Lagerstätten of the Early Cambrian Maotianshan Shale record an apparently sudden conquest of pelagic niches by ten phyla of metazoans. One of these phyla is Chaetognatha, a group of predatory marine worms. Given their role as major predators in modern planktonic ecosystems, the chaetognaths discovered in the Maotianshan Shale (Yunnan Province, South China) suggest that the pelagos at the time was already quite complex. Modern chaetognaths, however, can be divided into benthic and pelagic forms; the pelagic nature of Eognathacantha ercainella should therefore be validated by strong morphological evidence.Knowing that planktonic animals present morphological adaptations that increase their buoyancy, we studied the drag produced during the active phase of chaetognath locomotion for the modern forms Paraspadella gotoi (benthic) and Sagitta elegans (pelagic). By using a motion model developed by Jordan in 1992, we could calculate the resistive force produced by the undulatory movement of chaetognaths' bodies.This mechanistic approach evaluates the effect of three motion parameters (relative speed, total length, and tail ratio) on the drag force produced during locomotion. Our results show that the increase of size contributes to higher drag while the shorter tail of the pelagic form balances this effect by reducing the wetted surface subject to friction. For chaetognaths, therefore, a bigger body (both in length and width) and a shorter tail indicate a pelagic lifestyle, a finding that can be applied to the study of the fossil Eognathacantha ercainella. A discriminant analysis can confirm that the Early Cambrian chaetognath presents a pelagic morphology with similarities to modern bathypelagic and mesopelagic species.

This study examines the fishing productivity of handling with operated by a fisherman in Majene district, West Sulawesi. Fishing activity utilizing FADs as a fishing ground. Fishing Productivity was obtained from the weight ratio of the amount of catches and duration of fishing time. Fishing productivity is determined for each type of fish catches, namely skipjack tuna (Katsuwonus Pelamis), yellowfin tuna (Thunnus albacares), and mackerel tuna (Auxis thazard). The proportion of the total catches of skipjack tuna showed greater than other fish species. The relationship between fishing productivity with the time fishing is declining with increasing duration of time fishing. Cluster analysis showed that there are two clusters of fishing productivity for 23 fishing activity. Fishing ground with the largest production was in the FADs in 118031'44,8''E and 118°34'16.0"E, and 04030'25.6"S and 118029'37,3''BT. Large pelagic fish species observed is the skipjack tuna (Katsuwonus pelamis), yellowfin tuna (Thunnus albacares), and tongkol (Auxis hazard). Fishing productivity shows the downward trend and the fishing ground for the production of tuna, mackerel and yellowfin tuna fish highest in FADs at position 04026’06,3”S and 118031’44,8’’E ; 04030’25.6”S and 118029’37,3’’E.<br /><br />Keywords: FADs, fishing productivity, handline, large pelagic, majene<br /><br />ABSTRAK<br /><br />Ikan pelagis besar merupakan salah satu komoditi perikanan yang memiliki nilai ekonomi yang relatif tinggi, sehingga pengembangan perikanan pelagis besar dapat meningkatkan ekonomi masyarakat dan daerah. Tujuan penelitian ini adalah menentukan produktivitas penangkapan ikan pelagis besar menggunakan pancing ulur. Penelitian ini dilakukan pada Bulan Juli-September 2012. Penelitian ini mengkaji produktivitas penangkapan pancing ulur yang dioperasikan nelayan di Kabupaten Majene, Sulawesi Barat. Aktivitas pemancingan memanfaatkan rumpon sebagai daerah penangkapan ikan. Produktivitas penangkapan diperoleh dari perbandingan berat jumlah hasil tangkapan dengan lama waktu pemancingan. Produktivitas penangkapan ditentukan pada masing-masing jenis ikan hasil tangkapan, yaitu cakalang (Katsuwonus pelamis), tuna ekor kuning (Thunnus albacares), dan tongkol (Auxis thazard). Proporsi jumlah hasil tangkapan menunjukkan cakalang lebih besar dibandingkan jenis ikan lainnya. Hubungan antara produktivitas penangkapan dengan lama waktu pemancingan menunjukkan kecenderungan menurun dengan bertambahnya lama waktu pemancingan. Analisis kluster menunjukkan terdapat dua kluster produktivitas penangkapan selama 23 aktivitas pemancingan. Daerah penangkapan ikan dengan produksi terbesar berada pada rumpon dengan posisi geografi 04026’06,3”LS dan118031’44,8’’BT ; 04030’25.6”LS dan 118029’37,3’’BT. Produktivitas penangkapan menunjukkan tren menurun. Posisi geografi rumpon yang memiliki produksi tuna, cakalang dan tongkol adalah pada posisi 04026’06,3”LS dan 118031’44,8’’BT ; 04030’25.6”LS dan 118029’37,3’’BT.<br /><br />Kata kunci: rumpon, produktivitas penangkapan, pancing ulur, pelagis besar, Majene</p>

<p>Kegiatan alih muatan (transhipment) umumnya dilakukan pada kapal pukat cincin pelagis besar yang dioperasikan dengan sistem grup, maka implementasi Permen KP Nomor 57/Permen Kp/2014 menjadi efektif bagi armada tersebut. Kajian dampak kebijakan ini terhadap aspek perikanan dan sumberdaya tuna telah dilakukan di perairan WPP 716 dan 717 khusus bagi perikanan pukat cincin pelagis besar berbasis di Bitung. Untuk kajian ini digunakan data yang dikumpulkan enumerator pada tahun 2013-2014, data pengamatan di atas kapal tahun 2013, dan data kapal yang diperoleh dari Ditjen PSDKP dan WCPFC. Hasil analisis menunjukkan bahwa jeda operasi penangkapan armada pukat cincin yang dioperasikan di WPP NRI 716 dan 717 yang berbasis di Bitung telah mengurangi pasokan bahan baku ke pabrik pengaelangan tuna di Bitung dan sekitarnya sebesar ± 40.968 ton ikan tuna sejak ± 8 bulan terakhir. Dalam rangka memenuhi sebagian pasokan bahan baku ke pabrik pengalengan tuna tersebut, sejak akhir Agustus 2015 sebanyak ± 10 kapal pukat cincin pelagis besar jenis penangkap yang sebelumnya dioperasikan dengan transhipment menjadi tanpa transshipment. Pada kapal-kapal tersebut dilakukan perubahan palkah nya sebelum dioperasikan sehingga memungkinkan tidak melakukan transhipment selama trip operasi penangkapan. Kapal pukat cincin pelagis besar jenis penangkap yang berukuran 181-220 GT dengan kekuatan mesin 600 HP merupakan ukuran ideal. Dengan tanpa beroperasi ± 8 bulan memberikan peluang tumbuh dan memijah bagi ikan dan diperkirakan ± 40.968 ton tuna tidak ditangkap. Ukuran cakalang yang awalnya ± 41 cmFL menjadi ikan dewasa berukuran ± 61 cmFL. Madidihang yang awalnya berukuran 40-41 cmFL menjadi ikan dewasa berukuran ± 70 – 71 cmFL. Bagi ikan tuna mata besar yang awalnya berukuran 40 cmFL menjadi berukuran ± 64 cmFL dan ikan tuna matabesar masih memerlukan ± 15 bulan lagi hingga mencapai ukuran dewasa (Lm 100cmFL).</p><p> </p><p>The practice of transhipment at large pelagic purse seine fleet group system makes the implementation of regulaiton PERMEN KP Nomor 57/Permen Kp/2014 regulation is effective for the fleet. Study on impacts of the practice of transhipment to the tuna fisheries and resources in Indonesian FMA 716 and 717 based at Bitung has been conducted. D ata and information are used in the study were from port sampling program year 2013 and 2014, onboard observer program of 2013, 2015 ship database from the Surveillance Directorate General and WCPFC. The analysis showed that since last 8 months, the operational pauses of the fleet based in Bitung and operating on 716 and 717 WPP NRI have reduced ± 40,968 tonnes of raw materials to the tuna canneries in Bitung and surroundings. Since August 2015 about 10 large pelagic purse seiners that are previously operated as large pelagic purse seiners with transshipment become to large pelagic pure-seiner without transshipment. The fish hold of the purse seiner have been revitalized so that possible to be operated without transhipment during fishing trip. Large pelagic purse seiner 181-220 GT class indicated as ideal size purse seiner that operated without transhipment. Having operational pauses of 8 month, it provides opportunity of 40,968 tonnes of tuna to grow and spawn. It is estimated the size of skipjack from the initial size of 41 cm FL become matured fish with size about 61 cmFL. Yellowfin tuna from the initial size of 40-41 cmFL become matured fish with size about 70 – 71 cmFL. Bigeye tuna from the initial size of 40 cmFL become about 64 cmFL and need atleast about 15 month to become matured stage i.e. 100 cmFL.</p>

Kepadatan dan penyebaran sumber daya ikan di perairan banyak dipengaruhi oleh variasi kondisi oseanografinya. Untuk mengkaji interaksi antara kondisi oseanografi dengan sebaran spasial ikan pelagis di Laut Jawa, telah dilakukan penelitian hydro acoustic dengan menggunakan KR. Bawal Putih III pada 17 Oktober-11 November 2017. Akuisisi data akustik menggunakan multi beam Simrad ME (70-120 kHz) dengan posisi transduser dipasang pada lunas kapal. Parameter lingkungan (oksigen, pH, salinitas, klorofil, suhu) diukur menggunakan CTD SBE 19 plus V2 dan parameter oseanogafi fisik (arah dan kecepatan arus) menggunakan ARM current meter, keduanya diturunkan secara vertikal sesuai kedalaman pada 48 stasiun. Analisa korelasi antara parameter oseanografi dengan kelimpahan ikan dan distribusi spasial menggunakan analisis statistik PCA (Principal Component Analysis). Hasil penelitian menunjukkan densitas ikan pelagis dipengaruhi secara berturut-turut oleh salinitas, oksigen, klorofil, pH dan suhu. Urutan ini didasarkan pada jarak dan kedekatan terhadap garis yang dibentuk faktor lingkungan terhadap titik pusat korelasi. Komponen lingkungan yang memiliki interaksi langsung dengan kelimpahan ikan pelagis adalah salinitas dan oksigen. Kedua faktor ini merupakan faktor utama dalam kegiatan osmoregulasi dan pembentukan energi untuk tubuh ikan, sementara keempat faktor lingkungan lainnya (klorofil pH, suhu dan kecepatan arus) berkorelasi secara parsial terhadap keberadaan ikan pelagis.The density and distribution of fish resources in the waters are much influenced by variations in oceanographic conditions. To examine interaction between oceanographic condition with spatial distribution of pelagic fish in Java Sea, hydroacoustic research was done using KR. Bawal Putih III on October 17 to November 11, 2017. Acoustic data acquisition used Simrad ME multi beam (70-120 kHz) with the position of the transducer installed on the keel. Environmental parameters (oxygen, pH, salinity, chlorophyll, temperature) were measured using the SBE 19 plus V2 CTD and physical oceanographic parameter (current direction and speed) using the ARM current meter, both are lowered vertically according to depth at 48 station. Correlation analysis between oceanographic parameter with fish abundance and spatial distribution using PCA (Principal Component Analysis) statistical analysis. Results show that density of pelagic fish was influenced respectively by salinity, oxygen, chlorophyll, pH and temperature. This sequence based on distance and proximity to the line formed by environmental factors towards the center of correlation. The environmental components that have a direct interaction with the abundance of pelagic fish are salinity and oxygen. These two factors are the main factors in osmoregulation and energy formation for fish bodies, while the other four environmental factors (chlorophyll pH, temperature and current velocity) correlate partially to the presence of pelagic fish.

This research activity took place in Manado City, North Sulawesi Province with activities centered on the Tumumpa Fishery Harbor (PPP). The data were recorded from capture fisheries activity conducted in the Sulawesi Sea and its surroundings landed in the Tumumpa Fishery Harbor. The purpose of this study was to analyze the stock value and Maximum Sustainable Yield (MSY) of pelagic fish in the Sulawesi Sea based on the approach of the surplus production model (Model Schaefer). This research is expected to be used as a consideration in the management of pelagic fish stocks in the Sulawesi Sea, and can be used as a basis for further research. This research uses secondary data collection method in the form of statistical document and record available. The data taken, including fish catch and fishing effort or effort (trip), from 2012 to 2016 (5 years). The results show that production value is inversely proportional to the value of effort, where the value of production from 2012 to 2016 has decreased every year, while the value of effort from 2012 to 2016 has increased. This condition indicates that the presence of pelagic fish stocks in the Sulawesi Sea and surrounding areas has been and is experiencing a decline that impacts on the decrease of production every year with a large percentage and this condition also indicates the occurrence of potentially overfishing. The value of MSY utilization of capture fishery resources in the Sulawesi Sea based on Tumumpa Fishery Harbor data were 16,305.45 tons / year for HMSY and 1,664,59 trips / year for EMSY, with TAC of 13,044.36 tons / year.Keywords : Capture fishery, MSY, Pelagic, Surplus Production Model, Tumumpa ABSTRAK Kegiatan penelitian ini berlangsung di Kota Manado, Provinsi Sulawesi Utara dengan kegiatan berpusat di Pelabuhan Perikanan Pantai (PPP) Tumumpa Manado. Aktivitas perikanan tangkap yang ditelaah berlangsung di kawasan perairan Laut Sulawesi dan sekitarnya berdasarkan data PPP Tumumpa Manado. Tujuan dari penelitian ini adalah untuk menganalisis nilai stok dan Maximum Sustainable Yield (MSY) ikan pelagis di Laut Sulawesi berdasarkan pendekatan model produksi surplus (Model Schaefer). Penelitan ini diharapkan dapat digunakan sebagai bahan pertimbangan dalam pengelolaan stok ikan pelagis di Laut Sulawesi dan sekitarnya, serta dapat digunakan sebagai dasar untuk penelitian selanjutnya. Penelitian ini menggunakan metode pengumpulan data sekunder berbentuk dokumen. Data yang diambil adalah data tangkapan ikan dan upaya penangkapan ikan atau effort (trip), dari tahun 2012 sampai dengan 2016 (5 Tahun). Hasil penelitian menunjukkan nilai produksi berbanding terbalik dengan nilai effort, di mana nilai produksi dari tahun 2012 sampai 2016 mengalami penurunan setiap tahunnya, sedangkan nilai effort dari tahun 2012 sampai tahun 2016 mengalami peningkatan. Kondisi yang terjadi ini mengindikasikan bahwa keberadaan stok ikan pelagis di Laut Sulawesi dan sekitarnya telah dan sedang mengalami penurunan yang berdampak pada penurunan produksi setiap tahun dengan persentase yang cukup besar di mana kondisi ini mengindikasikan terjadinya overfishing. Nilai MSY pemanfaatan sumber daya perikanan tangkap di Laut Sulawesi berdasarkan data PPP Tumumpa Manado sebesar 16.305,45 ton/tahun untuk HMSY, dan 1.664,59 trip/tahun untuk EMSY, dengan TAC sebesar 13.044,36 ton/tahun.Kata Kunci: Perikanan Tangkap, MSY, Pelagis, Model Produksi Surplus, Tumumpa

The gut contents of three species of cumaceans: Eudorella splendida, Vaunthompsonia inermis and Campylaspis maculata, and three species of tanaids: Nototanais antarcticus, N. dimorphus and Peraeospinosus pushkini from the shelf of Admiralty Bay and two cumaceans: Diastylis mawsoni and Ekleptostylis debroyeri from the deeper Antarctic shelf were studied. With the exception of Campylaspis maculata, which is a predator or scavenger, and Ekleptostylis debroyeri, whose gut was filled with mud only, detritus was an important diet component of all the species studied. On the basis of qualitative and quantitative components of diatom taxa it can be concluded that the food of Diastylis mawsoni comes from the pelagial, whereas the food of the other peracarids is of benthic origin. Species inhabiting the shallowest waters consume almost exclusively epipelic food, whilst those living below the euphotic zone feed mostly on particles sedimented from the pelagial; taxa occurring at intermediate depths feed on pelagic matter, but also of epiphytic and of epipelic origin.

A long-term time series of plankton records collected by the continuous plankton recorder (CPR) Survey in the northeast Atlantic indicates an increased occurrence of Cnidaria since 2002. In the years 2007 and 2008, outbreaks of the warm-temperate scyphomedusa, Pelagia noctiluca , appeared in CPR samples between 45° N to 58° N and 1° W to 26° W. Knowing the biology of this species and its occurrence in the adjacent Mediterranean Sea, we suggest that P. noctiluca may be exploiting recent hydroclimatic changes in the northeast Atlantic to increase its extent and intensity of outbreaks. In pelagic ecosystems, Cnidaria can affect fish recruitment negatively. Since P. noctiluca is a highly venomous species, outbreaks can also be detrimental to aquaculture and make bathing waters unusable, thus having profound ecological and socio-economic consequences.

Jenis ikan pelagis kecil merupakan sumber daya ikan dominan yang terdapat di wilayah perairan Laut Cina Selatan. Terdapat beberapa jenis ikan pelagis kecil yang merupakan hasil tangkapan utama antara lain adalah ikan layang (Decapterus sp.) dan kembung (Rastrelliger brachysoma). Penelitian terhadap biologi reproduksi (perkembangan kematangan gonad, sex ratio, dugaan musim pemijahan, dan length at first maturity) telah dilakukan terhadap 3 jenis ikan pelagis kecil (Decapterus russelli, Decapterus macrosoma, dan Rastrelliger kanagurta) yang tertangkap di Laut Cina Selatan. Pengambilan contoh biologi terhadap ke-3 spesies ikan dilakukan di tempat pendaratan ikan Palembang, Pemangkat, dan Pekalongan pada tahun 2003 sampai dengan 2005. Hasil penelitian menunjukkan ada peningkatan nilai gonado somatic index yang seiring dengan bertambah ukuran ikan. Kejadian ini mengindikasikan perkembangan gonad ke arah kematangan. Pola fluktuasi gonado somatic index yang terjadi berdasarkan pada musim (cenderung lebih rendah pada musim barat, semakin meningkat pada akhir musim barat, dan mencapai maksimum pada musim timur dengan diikuti ada penurunan gonado somatic index). Dengan pola demikian ini, mengindikasikan pemijahan utama terjadi sejak akhir musim timur dan berlangsung beberapa bulan sampai dengan musim peralihan. Secara umum, populasi ikan yang tertangkap didominansi oleh ikan yang dalam kondisi belum matang gonad. Jenis Decapterus russelli mencapai kematangan gonad yang pertama (length at first mature) pada kisaran ukuran 18,6 sampai dengan 21,2 cm TL; Decapterus macrosoma pada ukuran 20,5 sampai dengan 21,9 cm TL, sedangkan Rastrelliger kanagurta pada kisaran ukuran 20,4 sampai dengan 22,3 cm TL. Small pelagic fish is one of the most dominant species caught in South China Sea which round scad and Indian meckerel are the main catches. Research on biological reproduction such as gonad somatic index, sex ratio, spawning season, and length at first maturity for three main pelagic species, i.e., Decapterus russelli, Decapterus macrosoma, and Rastrelliger kanagurta, was carried out during 2003 to 2005. Research result shows that there was a tendency that the increasing value of gonad somatic index occurred together with increasing the size of fish. The fluctuation of gonad somatic index was affected by season, the low value of gonad somatic index was found during northwest monsoon, conversely the high value of gonad somatic index occurred during southeast monsoon. This phenomenon indicated that the main spawning season occurred during southeast monsoon on several months before the next intermoon son coming. Generally, the small pelagic species in this area caught abundantly on the mature stage. Length at first maturity for Decapterus russelli observed in the range of 18.6 to 21.2 cm in TL, Decapterus macrosoma recorded in the range of 20.5 to 21.9 cm in TL, and Rastrelliger kanagurta found in the range of 20.4 to 22.3 cm in TL.

Penelitian ini bertujuan untuk mempelajari perbedaan pola sebaran ikan pada musim barat dan peralihan di perairan utara Semarang sampai dengan Brebes, berdasarkan pada pengambilan contoh akustik dan oseanografi pada bulan Desember 2005 dan Mei 2006. Hasil menunjukkan secara spasial, pada musim barat di perairan utara Semarang sampai dengan Brebes kepadatan ikan pelagis lebih besar di daerah yang lebih dangkal yaitu sebelah selatan pada kedalaman <40 m, semakin ke tengah kepadatan semakin berkurang. Dilihat dari nilai target strength yang terdeteksi yaitu antara -60 sampai dengan -50 dB bahkan didominasi oleh ikan -60 sampai dengan -55 dB, sasaran merupakan ikan pelagis kecil yang rata-rata mempunyai ukuran 4 sampai dengan 12,5 cm. Pada musim peralihan sebaran kepadatan ikan pelagis kecil cenderung lebih merata dengan jumlah yang lebih rendah daripada jumlah ikan pada musim barat. Faktor pergerakan arah arus dan keberadaan sumber makanan yang lebih besar pada musim barat diduga merupakan penyebab perbedaan tersebut. Ikan pelagis kecil pada musim peralihan berukuran lebih besar dibandingkan ketika musim barat, dengan nilai target strength yang terdeteksi antara -60 sampai dengan -45 dB atau sekitar 4 sampai dengan 22 cm dan didominasi oleh ikan yang berukuran -55 sampai dengan -50 dB atau sekitar 7 sampai dengan 12,5 cm. Sebaran kepadatan Ikan demersal hampir merata pada ke-2 musim tersebut, pada musim peralihan kepadatan lebih rendah daripada musim barat. Ikan demersal pada musim barat terdiri atas ikan berukuran kecil (-55 sampai dengan -50 dB) atau sekitar 7 sampai dengan 12,5 cm terutama di daerah pada kedalaman <40 m, semakin ke tengah ukuran semakin besar yaitu antara -50 sampai dengan -45 dB atau sekitar 12,5 sampai dengan 22 cm. Pada musim peralihan, ikan demersal dengan target strength -55 sampai dengan -50 dB terdapat di kedalaman <40 m. Ikan demersal dengan ukuran -50 sampai dengan -45 dB mendominasi periode ini. Pada kedalaman >45 m terdeteksi ikan -45 sampai dengan -35 dB yang berkisar 22 sampai dengan 70 cm. The aim of this study is to understood the difference of fish pattern distributions at North West and intermonsoon in North of Central Java waters, based on acoustic and oceanography sampling in December 2005 and May 2006. At North West monsoon, the density of pelagic fishes was more gathering in narrower areas <40 m, and low fish density was going to middle areas. Seen from target strength the value was detected about -60 to -50 dB and it was dominated by fishes -60 to -55 dB, the targets for small pelagic fishes are about 4 to 12,5 cm. At the intermonsoon, distribution of small pelagic fishes density tends to be flat, but fish density at this time was the lower than North West monsoon. The higly current direction and food source factor at North West monsoon may cause this difference. The size of small pelagic fishes at the intermonsoon was bigger than fishes at North West monsoon, which target strength value was detected about -60 to -45 dB or 4 to 22 cm and dominated by fishes -55 to -50 dB of about 7 to 12,5 cm. The density distribution of demersal fishes almost flat at both monsoon. How ever at intermonsoon, the demersal fishes density was lower than that at North and West season. Demersal fishes at North West monsoon consisted of small fishes (-55 to -50 dB) with size of about 7 to 12,5 cm especially in narrow areas <40 m, and fish sizes the larger (-50 to -45 dB or 12,5 to 22 cm) were going to the middle areas. At intermonsoon, there were demersal fishes with target strength -55 to -50 dB at <40 m. Demersal fishes with target strength -55 to -50 dB were dominant at this time. At areas >45 m it was detected fishes of -45 to -35 dB target strength of about 22 to 70 cm.

Pengelolaan perikanan skala kecil di Kabupaten Bangka pada beberapa kurun waktu terakhir menunjukkan produktivitas yang semakin menurun. Hal ini disebabkan oleh pengelolaan ruang laut yang tidak hanya dimanfaatkan sebagai daerah penangkapan ikan, tetapi juga sebagai wilayah eksploitasi penambangan laut. Penelitian ini bertujuan untuk mengetahui status pemanfaatan perikanan skala kecil di perairan Kabupaten Bangka. Penelitian dilakukan dengan menggunakan data primer dan sekunder; analisis bioekonomi digunakan pada ketiga zona daerah penangkapan ikan (DPI) dengan memisahkan sumberdaya ikan pelagis dan demersal untuk melihat status pemanfaatan perikanan pada masing-masing zona. Ketiga zona daerah penangkapan ikan didasarkan pada kondisi eksisting menurut RZWP3K Provinsi Kepulauan Bangka Belitung, yaitu: Zona A (DPI dengan IUP), Zona A1 (DPI dengan IUP tanpa kegiatan), dan Zona B (DPI tanpa IUP). Hasil penelitian menunjukkan bahwa perikanan pelagis Zona A cenderung economical overfishing; sedangkan perikanan demersal sudah menunjukkan kondisi economical overfishing; Zona A1 berada pada kondisi underfishing; serta Zona B berada pada kondisi underfishing. Pemanfaatan perikanan Zona A dan A1 tidak mencapai 50% TAC; sedangkan pada Zona B hanya 15% TAC. Agar pemanfaatan perikanan baik pelagis ataupun demersal dapat berkelanjutan baik secara ekologi maupun ekonomi, pengelolaan perikanan skala kecil di perairan Kabupaten Bangka perlu dilakukan pengelolaan input pada upaya tangkap yang berbeda-beda pada tiap zona serta pengelolaan ekologi dan ekosistem.Title: Management of Small-Scale Fisheries in The Coastal Waters of Bangka Regency with Bioeconomic ApproachManagement of small-scale fisheries in Bangka Regency has recently shown decreased productivity. This is caused by the management of marine area which is not only used as a fishing ground, but also as an area of exploitation for off-shore mining. Based on these conditions, this study aims to determine the level of utilization of small-scale fisheries in the waters of Bangka Regency. This research uses primary and secondary data; bio-economic analysis was carried out in the three fishing ground zones by separating pelagic and demersal fish resources to see the utilization status of each zone. The three fishing ground zones are based on the existing fishing ground conditions according to RZWP3K Bangka Belitung Islands Province, namely: Zone A (fishing ground with IUP), Zone A1 (fishing ground with IUP without activities), and Zone B (fishing ground without IUP). The results showed that Pelagic Zone A fisheries tend to be economical, whereas demersal fisheries have shown economical overfishing; Zone A1 is under fishing; Zone B is under fishing. The utilization of fisheries in Zone A and A1 does not reach 50% TAC, while in Zone B it is only 15% TAC. For the utilization of pelagic and demersal fisheries to be sustainable both ecologically and economically, the management of small-scale fisheries in Bangka Regency waters needs to carry out input management for different fishing efforts in each zone as well as ecological and ecosystem management.
