The economics of conflicting interests: Northern Baltic salmon fishery adaption to gray seal abundance

摘要: The successful conservation of gray seals has led to increased seal-induced damage the Atlantic salmon fisheries Baltic Sea. This paper addresses conflict between a formerly endangered species, seal, and professional fishermen, whose livelihoods are affected by both management. We develop bioeconomic model that incorporates age structure seal populations. To determine social optimum, we maximize discounted net present value trap fishery, taking into account presence in form losses, which describe using function. By choosing optimal combination fishing gear over time, obtain socially efforts, stock size, catch. In addition, study private effects introducing technology subsidy aimed at mitigating seal-salmon conflict. results suggest technological adaptation would effectively reduce cause conflict, while encouraging such shift economic responsibility from individual fishermen broader public.
