Optimum Allocation of Fishery Resources in the Gulf Palabuhahratu is a study that aims to study the optimum allocation of fisheries resources in the waters of the Gulf Palabuhanratu. Level of fish production, the amount or level of effort and resource rent value represents the optimum value calculated in this study. The optimum value is then used to determine the optimum volume of catch per level of effort, the amount of fishing gear, number of fishermen and rent-seeking optimum value for each fisherman.

Growth function of production surplus and Pontryagin Maximum Principles used as an approach for optimum allocation. This model uses components of the real input prices and costs are approximated by the consumer price index. Biological parameters, such as r, q, and K is estimated using the estimation model-Hilbron Walters (WH: 1976) and CYP (1992). Estimation model WH (1976) Logistic growth function-based, whereas CYP (1992) Gompertz growth function.

Analytical solution using Maple 9.5 for small pelagic fish resources in the surrounding waters of the Gulf Palabuhanratu with a discount rate of 4.04% yield optimal biomass value SDI (x *) amounted to 1888.85 tons, the optimal yield (h *) amounted to 1448.05 tons and optimal effort (E *) as many as 12 777-level trip fishing gear chart. Rent value of small pelagic fish resources to reach USD 1053.97 million, while the value of rents over time it reached USD 26088.56 million. Analytical results of the SDI demersal biomass yield optimal values (x *) of 7211.35 tons, the optimal yield (h *) amounted to 2758.30 tons and optimal effort (E *) as many as 11 250-level fishing tools fishing trip. Rent value of demersal resources to reach USD 1264.05 million, while the value of rents over time it reached USD 31288.36 million.

Result of calculation of optimum allocation of fish resources in the waters of the bay resulted in an optimal amount of catch (quota) per trip that can be caught by fishermen in the surrounding waters of the Gulf Palabuhanratu. Optimum catch per trip level chart to catch small pelagic fish at a discount rate of 4.04% is 113.33 kilograms, while the optimal catch level per trip fishing for demersal fish catch totaled 245.18 pounds. Optimal amount of fishing gear based on dynamic analysis is as many as 43 units of the chart to capture the level of small pelagic fish and as many as 38 units of fishing level to catch demersal fish. Consequently, the optimal expected number of fishermen chart is 85 persons and as many as 113 people fishing rod.
