Pengelolaan Perikanan Cakalang Berkelanjutan Dengan Pendekatan Bioekonomi Di Kabupaten Flores Timur (Sustainable Fisheries Management of Skipjack Tuna with Bioeconomic Approach in East Flores District)

Territorial waters of East Flores has the large potential of fish resources. One of them is skipjack tuna, where the utilization of these resources are used to meet the needs of the national and International market. This resulted in considerable pressure on resources, so it requires a calculation based on the optimization of the utilization of biological factors. This research was conducted to analyze the status of utilization of resources and looking for the best management regime in achieving sustainable fisheries. This research was conducted in the Larantuka, East Flores District, NTT Province in March to April 2014. This study uses a bioeconomic analysis which is accompanied by some estimate of the social discount rate. In this study, bioeconomic analysis using two approaches, namely input and output. The analytical method used is the CPUE (Cacth Per Unit Effort) analysis, biological and economic parameters, optimization of estimation static and dynamic. Dynamic optimization in this analysis, conducted with estimated level of the sensitivity social discount rate value to resource extraction. The results in this study shows that in the period 2003-2012, the skipjack tuna resource utilization efforts have not experienced symptoms of overfishing, so the chance in an effort to utilize the resource is still wide open

Model Bioekonomi Eksploitasi Multispesies Sumber Daya Perikanan Pelagis Di Perairan Selat Bali (Bio-economic Model of Multispecies Exploitation of Pelagic Fishery Resources in the Bali Strait)

Bali Strait has potential abundance of pelagic fishery resources such as Indonesian oil sardine (lemuru), frigate mackerel (tongkol), scad mackerel (layang), short-bodied mackerel (kembung) and others which can be caught mostly using purse seine. Fishery resources are combined and also known asmultispecies; therefore this research aimed to analyze the model of bio-economic multispecies exploitation of pelagic fishery resources in Bali Strait. The analytical methods that used in this research were estimated dynamic model of Walters and Hilborn (1976) and analysis of bio-economic model. The results showed that actual production of exploitation of pelagic fishery resources in Bali Strait, was lower than the rate of sustainable production especially Indonesian oil sardine and short-bodied mackerel. Production and fishing effort were below the actual optimal value. The management of pelagic fishery resources in Bali Strait did not show a good level of economic efficiency. Thus the exploitation of pelagic fishery resources in Bali Strait using purse seine could still be increased

Pengaruh Perbedaan Atraktor Terhadap Hasil Tangkapan Juvenil Lobster Dengan Korang Di Desa Sangrawayan, Palabuhanratu (the Effect of Different Attractor Against Catch of Juvenile Lobster by Korang in Sangrawayan Village, Palabuhanratu)

This research has been done in Palabuhanratu bay, Indonesia. Juvenile lobster (Panulirus sp.) is the main target fish in this research. This research was used Fish Aggregating Devices with two different types of attractor. This research was aimed to known differences in the effectiveness of attractor that had been calculated used on Mann-Whitney Methode. Attractor which used for comparison were seaweed and palm leaf as a test and a seaweed as a control. Korang was a tool that used to gotten a data and put a attractor. The result of comparition show that a total of catches with seaweed and palm leaf more than seaweed. From the result concluded that seaweed and palm leaf more effective than seaweed
