Abstract
The paper presents a bioeconomic analysis determining the resource rent and optimal effort of the Greenland shrimp (Pandalus borealis) fishery of the Davis Strait. The model simulates the expected yield and revenue applying a constant fishing effort on a varying shrimp stock. Application of selective gears as a measure to restrict over-exploitation is discussed in both biological and economic terms. Variability is introduced into the model by generating the stock size by age randomly from a distribution function developed from random numbers. Applying a lognormal distribution, the coefficients of variance are generated for both revenue and yield about 10 times higher than when a uniform distribution is applied. The optimum resource rent is obtained at an effort level about 50% lower than the one generating maximum biological yield. At constant effort a mesh size increase from 43 mm to 55 mm may reduce catches but increases revenue by 50%.
