Estimated at around 20% of global catches, i.e. between 11 and 26 million tons, illegal fishing or IUU fishing (Illegal, Unreported and Unregulated) represents a loss of 10 to 23 billion euros each year worldwide. In addition to this economic observation, these illegal practices permanently endanger the management and conservation measures in place, food security and the living conditions of communities. Fighting illegal fishing therefore means promoting environmental, social and economic development.
