Illegal, unreported and unregulated fishing (IUU) is a broad term that refers to fishing without the permission of a nation state, or in contravention of its laws and regulations; unreported or misreported fishing; and fishing that is conducted in an area with no applicable conservation or management measures.
IUU is an issue around the world. The fishing industry observers believe IUU occurs in most fisheries, and accounts for up to 30% of total catches in some important fisheries.
