What is IUU?What is IUU? Complex definition: FAO / International Plan of
Action to Prevent, Deter, and Eliminate Illegal, Unreported and Unregulated Fishing (IPOA-IUU)
Essentially is ‘Catches taken within an EEZ which are both illegal (contravene rules & regulations) and retained, and which are usually unreported, and all unreported catches taken in high seas waters subject to a Regional Fisheries Management Organization’s (RFMO) jurisdiction’ (MRAG 2008).
Includes a ‘multitude of sins’.
Where & at what costs?Where & at what costs? A global problem - Occurs in most regions. Not only in EEZs of developing world & high-seas
areas, but also in EEZs of major developed countries.
Total value IUU losses worldwide are ca. 11 – 26 million tonnes, worth USD 9 – 25 billion (Pauly et al. 2002, MRAG 2005, EC 2007, Agnew et al. 2008).
Products from IUU imports into the EU conservatively estimated at EUR 1.1 billion (EC COM/2007/0601).
European Court of Auditors has criticized fisheries control within EU waters & proposed measures to tackle the problem (ECA 2007).

• For exampleFor example: EU fisheries ministers agreed : EU fisheries ministers agreed TACs in 2006 on average 45% higher than the TACs in 2006 on average 45% higher than the catches recommended by ICES scientific catches recommended by ICES scientific advice. Science-based advice has often formed advice. Science-based advice has often formed the basis for ‘talking-up quotas’ (Aps et al. the basis for ‘talking-up quotas’ (Aps et al. 2007).2007).

There are few technical impediments to obtaining the necessary data.
Policy, legal and institutional arrangements, particularly at the international level, need to be more firmly established & actively implemented, in particular flag State duties & responsibilities.
