Abstract

Crab (Portunus pelagicus) an export product, many caught by fishermen Pasuruan. Until now production is still relying on the catch from the ocean given the results of cultivation is not allowed. The high economic value of crabs has increased the frequency of the catch effort, it affects the willingness Rajungan existing resources because that is necessary to study on the resource potential of the sustainable fishery in Pasuruan, in order to create a sustainable resource. The specific objective of this study to:/ determine the resource potential of the stock reserves crabs (Portunus pelagicus) sustainable fishery in Pasuruan by applying the model of Walter and Hilborn method to obtain the maximum catch (CMSY), efforts to catch (EMSY) as well as the potential for sustainable (Pe). This research uses the descriptive method and the sampling technique is purposive sampling. The results showed that the value CMSY 61.860,7 kg/year, EMSY 788 750 trips/year, the type of fishing gear gill nets remains a fishing gear standard, the value of the growth rate intrinsic population (r) Rajungan amounted to 66.93% per year, maximum carrying capacity of the water (k ) of 369,703.9141 kg/year, the ability to capture (q) of 0.00000012 and resource potential Rajungan (Pe) of 184,851.9571 kg/year. The potential of biomass reserves in 2030 amounted to 82886.95 kg open access conditions, so when compared with the potential for sustainable by 2030 only the remaining 40%.
