Optimum Fisheries Resources Allocation at the Waters of Palabuhanratu Bay : Demersal Fisheries Resources

In this paper, production surplus function and Pontryagin Maximum Principles were used as the approach for optimum allocation. Production surplus function and Pontryagin Maximum Principles were used as the approach for optimum allocation. Biological parameter, such as r, q, and K estimated with Walters-Hilbron (WH: 1976) and CYP (1992) estimator models. WH (1976) was basically using Logistic growth function, while CYP (1992) was basically using Gompertz growth function. Based on the analytical solution using MAPLE 9.5 for demersal at Palabuhanratu Bay with annual continues discount rate ( δ)=4,04%, per year optimal biomass (x*) = 7.211,35 tonnes, optimal yield (h*) = 2.758,30 tonnes and optimal effort (E*) = 11.250 trip in hand line standard level. The demersal resources rent is estimated Rp 1.264,05 million, while its over time rent = Rp 31.288,36 million. Using annual continues discount rate of 4,04%, optimal harvest per trip as hand line standard level of effort is 245,18 kg. The number of optimal fishing gears based on the dynamic analytical model is arround 38 unit as hand line standard level. Consenquently, optimal number of hand line fishermen can be calculated to be 113 people, respectively
