Aquaculture, Capture Fisheries, and Wild Fish Stocks
AbstractIn a general equilibrium model, this paper examines how the rise of aquaculture and the decline of wild fish stocks are related. Two factors, population growth and technological improvement in aquaculture, have been studied in an aquaculture restricted entry case and an aquaculture free entry case. Both factors raise aquaculture production, while changes in wild fish stocks hinge on entry conditions. In the restricted entry case, population growth reduces wild fish stocks, but technological progress in aquaculture raises them. In contrast, in the free entry case, only technological advance in aquaculture affects and raises wild fish stocks.
