Illegal fishing is a sort of fishing in which boats violate the regulations of a fishery that is controlled by a coastal state or on the international oceans. Unreported fishing is one type of IUU fishing, in which fishing is not reported to the appropriate authorities or is reported incorrectly. Another sort of fishing is unregulated fishing, which is typically carried out by boats without nationality or boats flying the flag of a nation that is not a member of the regional organisation that regulates that fishing area or species. Wherever such fishing occurs, whether it be in open sea or coastal waters, the international community uses the expression "IUU fishing" to denote an activity that does not conform with national, regional, or global commitments for fisheries conservation and management.
