Abstract

Stock status of Yellowfin tuna in Indian Ocean on southern water of East Java currently is predicted undergoing overfishing or close to overfishing which is very alarming from sustainability context. A research has been done on Yellowfin tuna fisheries sustainability based on ecology, economy, technology, social and institutional dimensions. Collected data are analyzed using RAPFISH (multidimensional scaling/MDS, leverage analysis, monte carlo analysis), and comparison pairwess analysis to asses multidimensional sustainability of Yellowfin fisheries.Research result shows that Rapfish index for ecological sustainability is 57.83%, whereas economical, technological, social and institutional sustainability are consecutively: 68.14%, 98.03%, 44.89% and 47.88%.  Multidimensional sustainability status assessment result show sustainability index 64.54 %, or Fairly Sustainable. Of those dimensions, social and institutional dimension have the lowest proportion in Yellowfin fisheries in Indian Ocean economic exclusive  zone (EEZ) they are 7.63% and 4.24 %. Keywords: yellowfin tuna, sustainability, EEZ, Rapfish

Abstract

The objective of the research is to explain about the rules of the traditional social institution, especially characteristic and typology of property rights on artisanal fishery management system at Abang island. Traditional institution pattern commonly has function for keeping continuity of coastal resources, so management that did by local fisherman society in coastal villages feel to keep well fishery resources and ecosystem, not disturbed by capture activity for example intake of rock, bombardment of fish and usage of potassium. Study case method that using is rural rapid appraisal (RRA) for coastal community. This research was done in Abang island village Galang subdistrict Batam city, try to identify and documentating several characteristic and typology of property rights on artisanal fishery at Abang island village. Based on result of research there are 8 fishing gears that dominant used by local fisherman, and other 2 modern fishing gears. Operation of trawl that has been prohibited based on Keppres No. 39/1980, still found in territorial water of Abang island. Eight of fishing gears that operated by fisherman, had fishing ground in around of territorial coastal water, farthermost catch fish by distance 3 or 4 miles from coast line. Generally fisherman here included small scale and traditional fisherman category, meant they become fisherman hereditarily, heritage of their parents, by using simply fishing gears, but they orientated to market, most of catch fish and prawn sold to merchant and tauke, called artisanal fisherman. For appliance catch selected like line, fisherman of Abang island catch fish collectively by using fish aggregating device cooperation result among fisherman. Most of fishing gears used by fisherman in this area are trap, line, longline, setnet, gillnet, fish cage, seine and fish-net. From a number of fishing gears divided again become some types, like net consist of beach seine, apollo net (trammelnet), trawl kara ( Lobster), stromateus net, gillnet and crab net.

Abstract

ABSTRACTFish stock in marine is dynamic due to fluctuation in the annual total catch. Consequently, the estimate number of fish stock changes yearly, without exception in the coastal of Cilacap District. This current study was intended to reassess the condition of fish stock utilization in the coastal water of Cilacap in 2012. Data of fish production, effort, fish price, and effort cost in 1999-2012 are taken from the Office of Fisheries Agency of Cilacap District. Analysis of fish stock condition is carried out using Gordon-Schaefer bioeconomic model. The results showed that utilization of marine fish resource in the coastal water of Cilacap District was in the condition of over fishing both in terms of MSY or MEY.Key words: fish stock assessment, Gordon-Schaefer model, small scale of fisheries-------ABSTRAKStok sumberdaya ikan di suatu perairan laut selalu dinamis karena jumlah penangkapan ikan berubah setiap tahunnya. Konsekuensinya adalah bahwa dugaan stok ikan di suatu lokasi perairan juga berubah setiap tahunnya, tidak terkecuali di perairan pantai selatan Kabupaten Cilacap Provinsi Jawa Tengah. Penelitian ini bertujuan untuk menduga status tingkat pemanfaatan stok udang oleh nelayan skala kecil di perairan pesisir Kabupaten Cilacap dengan tahun acuan 2012. Data produksi udang, data upaya penangkapan, data harga udang, dan data biaya per upaya penangkapan tahun 1999-2012 bersumber dari Dinas Kelautan dan Perikanan Kabupaten Cilacap. Analisis kondisi tingkat pemanfaatan stok ikan dilakukan menggunakan model keseimbangan bioekonomi Gordon-Schaefer. Hasil penelitian menunjukkan bahwa pemanfaatan sumberdaya ikan laut di wilayah pesisir Kabupaten Cilacap telah berada pada kondisi lebih tangkap (overfishing) baik dari segi MSY maupun MEY.Kata kunci: pendugaan stok ikan, model Gordon-Schaefer, nelayan skala kecil

Abstract

Kegiatan penangkapan telah menyebabkan terjadinya penurunan stok dan biomasa simping. Penurunan itu dapat terjadi pada stadia spat, muda, dan dewasa. Perubahan ukuran tangkap yang semakin kecil juga merupakan pertanda bahwa telah terjadi upaya penangkapan yang berlebih. Berdasarkan analisis kepadatan, terdapat adanya perbedaan jumlah dan biomassa antara waktu pengamatan. Peningkatan biomassa yang terjadi, yatu 0,46 gram per 2 minggu dan laju penurunan kepadatan sebesar 0,657 ind/2 minggu. Pada bulan April kepadatan rendah, biomassa rendah, dan rasio biomassa terhadap kelimpahan juga rendah. Artinya tekanan penangkapan yang terjadi maupun pengaruh lingkungan besar saat bulan April.Kata kunci: biomassa, kelimpahan, simping, Kronjo

Abstract

This study aims : (1) to analyze the status of coastal ecosystems, (2) to analyze factors that affect the quality of coastal ecosystems, and (3) to prepare the direction on spatial planning in coastal areas of Ambon Bay Area. The analytical method used in this study is the analysis of ecosystem status, principal components analysis, analysis of Geographic Information Systems (GIS) and analysis of dynamic systems. The results showed that the condition of ecosystem status damaged in 2008, whereby, the status of mangrove ecosystems is moderate with a density of 1100 trees/ha, the status of seagrass ecosystems damaged by percentage cover of 38,76%, and the status of coral reef ecosystems are damaged by the percentage of live coral is 42,27%. Ecosystem conditions in Ambon Bay Area is affected by land use on land, namely forest area and population. Refferral of land use planning in Ambon Bay Areas wich recommended in this study for a period of 20 years of protected areas and cultivated areas. Protected areas is aimed at 9.480,70 ha or 41,21% of land area, while the allocation of space for the cultivation area is 10.416,30 ha (58,79% of land area). To reduce the pollutant into the waters, planned buffer zones (coastal and riverine border for 11,69% of land area), which serves to absorb pollutants and protect the inland waters of the tidal influence, while still controlling the waste coming into water By using dynamic systems analysis, created the scenario of land use planning in Ambon Bay Area that integrates land and wet land. The scenario used in this study is the optimistic, pessimistic and moderate scenarios. The variable that is used to determine of policy scenarios spatial planning based on the rate of population growth is 2,5% per annum, while variable forest area of at least 30% of the area. Of the three scenarios, the scenario chosen for the land use planning policy in Ambon Bay Areas in the future is to use the moderate scenario. The simulation results moderate scenario, the status of coastal ecosystems is improved from the criteria of the coastal ecosystem damaged by coastal ecosystems index 44,44% in 2008 turned into good condition with the index of coastal ecosystems 88,89% in 2029
