The U.S. Department of Commerce - in conjunction with the National Marine Fisheries Service; the Regional Fisheries Management Councils; and other relevant federal agencies, state fisheries management agencies, and tribes - should develop fishery management plans that remove the human causes of fish population decline, including the elimination or mitigation of habitat degradation activities and incentives that encourage such activity. These plans should adopt the precautionary principle in decision-making that in the face of scientific uncertainty, err on the side of resource conservation. These plans should address reduction in capitalization; improvement in the precision of science used for decision-making; quantitative assessments of social and economic effects associated with specific fisheries; public and private mitigating actions; reductions of bycatch, or sea life incidental to the catch of targeted species; improved cooperation and coordination among fisheries and land management agencies, private industry, hydropower agencies, and other stakeholders; and better programs to prevent accidental introduction of exotic species.
