Efektivitas Pemanfaatan Rumpon Pada Operasi Penangkapan Ikan Di Perairan Kei Kecil, Maluku Tenggara

One 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

Fishing Zone in Karimunjawa National Park

Karimunjawa National Park (KNP) consists of 7 zones i.e., core, protection, tourism, residence, rehabilitation, cultivation, and traditional fisheries utilization zone. Fishing activities in the traditional fisheries utilization zone (TFUZ) was not optimal because of limited of fishing zone information. The objective of this study was to determine the fishing zone based on major fish for each fishing gear. This study was conducted in KNP from October to December 2009. The major fish resources were determined through analyses of comparative performance index (CPI). Fish resource potential was analyzed by bio-economic model. The existence of fish resources were used as a basis of arrangement of fishing gear arround the fishing zone, through consideration of fishing gear characteristics, the characteristics of waters, the probabilities of conflict, degradation of fish resources, and regulations. Map of fishing zones were created using geographicl information system. Results showed that potential fishes around the TFUZ were reef fishes such as trevallies, yellow tail, and grouper. The potency of reef fishes was about 149 tons/year and pelagic fish of 19,080 tons/year. Fishing zones around the TFUZ consisted of (1) area of 0-3 miles from coastal line which was allocated as the fishing zone of reef fishes using hand line and fish trap, (2) area of 3-4 miles from coastal line which was allocated as demersal fishing zone using bottom gillnet, (3) area of 0-4 miles from coastal line which was allocated as pelagic fishing zone using surface gillnet, and (4) area that more than 4 miles which was allocated as pelagic fishing zone using dynamic fishing gear (troll line), and boat lift net
