Abstract: A significant problem hindering the emergence or the continued growth of aquaculture in many marine areas is the conflict that arises among it and other ocean uses. We develop a framework to clarify the choice of the optimal scale of aquaculture when that use impacts a commercial fishery. We identify a range of potential impacts, both positive and negative, and analyze how one or more might affect the carrying capacity of a fish stock. We conduct a numerical simulation to illustrate a case where aquaculture and fishery uses interact in the ocean and compete in the product market, and we find that an ocean area could be devoted exclusively to aquaculture. This result depends strongly upon assumptions about the nature of the interaction, the geographic distribution of fish, and the aquaculture production technology. We also investigate the behavior of the model when both uses are able to coexist.
