Abstract

The production of barong shrimp (Panulirus spp) is mostly caught from the sea, although restocking efforts have been initiated, the results have not had an impact. The high demand and its economic value increase the frequency of catching efforts, therefore information on the stock condition of barong shrimp (Panulirus spp) and their distribution habitat is needed to create a sustainable resource. This study aims: to obtain the stock of sustainable potential and the distribution of their habitat in the waters of East Java. The research method uses the Walter-Hilborn model approach, the results conclude that the standard type of fishing gear is Trap, the prediction of potential biomass stock in open access conditions in 2030 is 37,763.64 Kg, the remaining stock in 2030 is 21 percent ( %), sustainable fishing effort 143,2000 trips/year, maximum sustainable catch 45820.15kg/year, fishing power 0.0000004, habitat distribution dominance in Water Management Area 712.

Abstract

Blue swimming crab (Portunus pelagicus) as an export product relies mostly on catches, one of which is in Fishery Management Area 712, where this research was carried out. The frequency of fishing efforts continues to increase because of its high economic value; however, there is not much information about the resource as a basis for following up on Law Number 45 of 2009 concerning measurable fish catches based on control output. Descriptive research method with the aim of mapping crab resources based on the "Walter-Hilbron Non- Equilibrium Model" The results showed that the maximum catch production (CMSY) was 63,886.114 kg/year with standard Trammel net fishing gear, intrinsic growth was 50.91%/year, the carrying capacity of the waters was 50195,336 Kg/year, dominant species was Portunus pelagicus, Optimum effort (Eopt) 6363750 trip/year with a resource potential of 25097.668 kg/year. This information forms the basis for resource mapping in order to increase inclusive and sustainable economic growth.
