- W3206601697 abstract "A renewable natural resource system such as a fishery involves both economic and ecological principles. In a natural state, fish populations reach an equilibrium level based on the carrying capacity of the environment. Human exploitation of the resource can be sustainable provided that it is consistent with this natural carrying capacity. Economic analysis of fisheries suggests that economically efficient resource use can be compatible with ecological sustainability. Setting annual harvest equal to natural growth, we can then identify an economically optimal equilibrium for the harvest level that maximizes net social benefit and is also ecologically sustainable. But open-access conditions, without harvest limits, create a strong tendency toward overexploitation in many fisheries and can even lead to the collapse of the fishery. On a global scale, fishing fleet capacity has continued to increase, with the result that over 90% of the world’s fisheries are being fished at or above the maximum sustainable yield. In recent years, despite an increase in global fishing effort, wild catch levels have remained relatively constant. Policies for maintaining sustainable yield and rebuilding depleted fisheries can involve a combination of regulation and market mechanisms. International conventions have set guidelines for territorial rights and management practices. Countries can require fishing licenses or impose quotas to limit access to the fishery. Region-wide quotas can be difficult to enforce, but systems of individual transferable quotas have been successfully implemented. Fish is an important protein source, especially in the developing world, where demand can be expected to grow as population and income rise. Consumption patterns can be modified to promote more sustainable fisheries management through consumer awareness and certification or ecolabeling programs. With little potential to increase global wild fish catch, increasing fish demand will need to be met through expansion of aquaculture. Aquaculture has great potential but can also involve significant environmental costs. Recent efforts to reduce the environmental impacts of aquaculture show promise, but more progress is necessary." @default.
