The Bioeconomics of Resource Rehabilitation: A Commercial-Sport Analysis for a Great Lakes Fishery
We construct a fishery model which simulates: (a) stochastic population fluctuations and (b) harvest shifts between commercial and sport user groups. This model then assesses, for both commercial and sport harvesters, the bioeconomic impact of an ongoing rehabilitation plan for the yellow perch fishery of Green Bay, Lake Michigan. Overall economic gains from this plan are positive, with sport anglers reaping sizeable benefits, while commercial harvesters lose moderately. Using probing exercises which approximate economic optimization, the efficient allocation of harvest between sport and commercial user groups is also explored. Uncertainties about sport effort levels greatly influence this optimal allocation.
