Measures by which a national government, regional or state authority attempts to influence or control the behavior of individuals, companies, and communities in the fisheries sector to achieve certain objectives. The measures can be of varied kinds, including fiscal measures, (e.g., taxes, subsidies, public investments, etc.); trade measures (e.g., import and export duties; quotas); social measures (health and education services); regulations (i.e., on food quality; means and types of fish harvesting; individual transferable quotas); and others.
