Get PDFMarine ornamental reef fish trade is a huge industry with trade value USD 200-350 million/ year. Seribu Islands, Jakarta is one of the main ornamental reef fish catch area in Indonesia. The aim of this study was to compare ornamental fishing activities with total allowable catch (TAC). Ornamental reef fish catch data were collected from fishermen annually within 2007-2009, while reef fish population data are collected using underwater visual census every two years. The results showed that the total catch of 18 marine ornamental reef fish species exceeded TAC in 2007. Then there were 22 species in 2008 and 17 species of marine ornamental fish in 2009 that their catches were more than TAC. In addition, fish that are always included in the ten highest caught fish within 3 years were Cryptocentrus cinctus, Pomacentrus alleni, Pterosynchiropus splendidus, Premnas biaculeatus, and Amphiprion ocellaris. Their catches exceeded TAC.Key words: Marine ornamental fish, Seribu Islands, Total Allowable Catch (TAC

PERUBAHAN GILLNETTER MENJADI TROLL LINER DI PPN PALABUHANRATU (Changes of Gillnetter into Troll Liner in PPN Palabuhanratu)
Get PDFABSTRACTFishing fleet in Palabuhanratu, especially for big pelagic fish such as tuna has shown increasing significantly since 2008. This is caused by implementation of rumpon (fish aggregating device) technology that makes fishing activities more efficient due to more exactly fishing ground. This condition made some gillnet fisherman modify their boat to troller that considered having high ability to catch tuna. The aimed of the research was to determine parts of gillnetter that can be modified to be operated as troller. The result showed that only upper parts of gillnetter that had significant modification to be operated as troller. Some upper part was reduced, the roof was eliminated and fish hold was added from 2 to 3 rooms. A little addition of buildings was constructed at the bow and new engine mounting was constructed as well to reach appropriate speed.Key words: gillnetter, modification, Palabuhanratu, troller-------ABSTRAKArmada penangkapan ikan pelagis besar, khususnya perikanan tuna, di Palabuhanratu mengalami perkembangan yang sangat pesat sejak tahun 2008.

TINJAUAN HUKUM DAN KEBIJAKAN KAWASAN KONSERVASI LAUT (KKL) MUKIM IE MEULEE, KOTA SABANG: Suatu Implementasi Pengelolaan Perikanan Tangkap di Pulau Kecil
Get PDFThe coastal area of Weh Island is divided into sub-districts (lhok) which are managed by traditional leader known as Panglima Laot. The Panglima Laot has the authority to regulate customary laws that aimed to bring social harmony and resolve conflicts concerning the marine resource use. In Anoi Itam and Ie Meulee of the east coast of Weh Island, the communities have high awareness toward the sustainable of the natural resources use, and this has led to the implementation of gear restrictions and no fishing zones regulations as part of their customary laws. These regulations have generated conflict with the other custom community, because the other custom community claimed that these existing customary regulations do not have legal base regulations. Gap analysis and analytical hierarchy process was used to analyze and describe the regulation that can be used as their optional regulation base. The result indicated that the Weh Island custom community had chosen a marine protected area that managed by community through Panglima Laot adopting regulations that recognised by local government. In the process of implementation, the determination area is a key priority (36.92%) followed by the establishment of management institutions (23.92%), financing (21.19%) and surveillance (17.94%)
EFEKTIVITAS PEMANFAATAN RUMPON PADA OPERASI PENANGKAPAN IKAN DI PERAIRAN KEI KECIL, MALUKU TENGGARA
Get PDFOne of ways to increase the fishing operation effectiveness is done by using fish aggregating device (FAD) called rumpon. The types of FAD used in Kei Kecil waters made from bamboos or plastic drum material. This research objectives are (1) determining catch composition around FAD, (2) comparing the effectiveness of two types of FAD on fishing operation, and (3) comparing the effectiveness of fishing gears, operated around the FAD. The method that used in this research was doing survey through observing fishing activities around the FAD. Fishing gear and FAD samples were determined through purposive sampling method. These data were collected from August to October 2007 in Kei Kecil Waters of South East Maluku. The kind of fish catch around FAD were scad mackerel, frigate mackerel, and barred spanish mackerel. The most dominant of catch was scad mackerel (80%), whereas percentage e of frigate mackerel and barred spanish mackerel were 19% and 1%. The composition of the length size of scad mackerel, frigate mackerel, and barred spanish mackerel were dominated by the large size. Type of bamboo FAD was more efective compared with the plastic drum FAD type. Purse seine fishing was more efective compared with gillnet and troll line fishing that operated around rumpon

Get PDFABSTRACTCilacap waters are rich with shrimp resource, particularly from Penaidae spp species, such as shrimp Jerbung (Penaeus merguensis) and shrimp Dogol (Metapenaeus endevouri and Metapenaeus ensis). Statistic data of shrimp in Cilacap showed shrimp production keep on declining, from 1,118,644 kg in 2004 to 818,595 kg in 2008. The declining production is suspected due to the increasing intensity of catching and the damage of ecology in coastal areas, particularly the mangrove. This research is aimed at mapping the mangrove areas, and estimating stock of shrimp resource in Cilacap. Data analysis was conducted by using spatial analysis and analysis of potential resource of fish. Results of the analysis showed that estimated mangrove forest in Cilacap in 2005 was about 14,502.55 ha, reduced to about 9,326.71 ha in 2007 and continue to decline to about 2,618.78 ha in 2009. Estimated score of MSY shrimp is 955,493.34 kg/year, with optimum catch 55,014.68 trips.Keywords: analysis of surplus production, Cilacap, mangrove, shrimp, spatial analysis------ABSTRAKWilayah perairan Kabupaten Cilacap kaya akan sumberdaya udang, khususnya dari jenis Penaidae spp., diantaranya yaitu udang jerbung (Penaeus merguensis) dan udang dogol (Metapenaeus endevouri dan Metapenaeus ensis).
