Exploration of Skipjack Fishing Ground Through Sea Surface Temperature and Catches Composition Analyzes in Palabuhanratu Bay Waters

Fishing ground condition is usually affected by oceanographic parameters. One of the oceanographic parameter that had been used in forecasting the availability of pelagic species such as skipjack is sea surface temperature (SST). Skipjack fish is the main target for boat seine net fishery in Palabuhanratu Bay from June to October 2007. Information on skipjack fishing ground availability is very important in order to optimize fishing operation. The purposes of the study are: to determine the SST distribution, to analyze the catch composition of skipjack, to determine the relationship between SST and skipjack catch, and to forecast the skipjack fishing ground in Palabuhanratu Bay from August to October 2007. The research consist of two stages. The first stage was conducted in Palabuhanratu Bay waters in August-October 2007, using survey method, with ten samples of boat seine net (payang). The second stage conducted on December 2007 to collect the SST data, which downloaded from the internet. The range of SST in Palabuhanratu Bay waters ranged from 22oC - 29oC in August 2007, 21oC - 27oC in September 2007 and 20oC - 31oC in October 2007. The SST had no significant effect on catch volume of skipjack in Palabuhanratu Bay during August until October 2007, but gave effect to the size distribution. The big skipjack distributed at the wide range of SST, but the small skipjack distributed at the narrow range of SST. The potential fishing ground of skipjack in Palabuhanratu Bay during September 2007 was found at Teluk Ciletuh, Ujung Karangbentang, Cimaja, Teluk Cikepuh, Ujung Genteng, and Gedogan waters

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

Zonasi Perikanan Pasi Untuk Kepentingan Pemanfaatan Secara Berkelanjutan Sumberdaya Ikan Kakap Merah Di Kepulauan Lease (Pasi Zone for Interest Sustainable Utilization of Red Snapper Resources in Lease Islands)

Pasi is a specific fishing ground for Red Snapper in Lease Islands. Recently, the exploitation of the red snapper population is tend to increase due to high demand of local, regional and International market as well as object for fishing tourism. This condition will threat the sustainability of the resources as if it is unmanaged in good way. Zone determination is one of the alternatives of good fisheries resources management. If it is done in a right way, it will add value to community without disturbing the sustainability. The objectives of the present study were to determine fisheries pasi zone to the sustainability importance of red snapper resources in Lease Islands. Data used included study of potential of red snapper resources, oceanographically condition, fishing ground (pasi), and fisheries value system namely basic value of ecological component, social and technology as well as PRA method (Participatory Rural Appraisal). Based on the criteria which were formulated of all aspects, specific zonation was made for pasi region in Lease Islands. The analysis showed that there were 4 out of 25 pasi determined as shelter zone, 21 pasi was for sustainable fisheries zone sub-zone of catch whereas 13 pasi was determined as utilization zone sub-zone fishing tourism
