The document estimates that global fisheries subsidies total over $30 billion per year. Around 66% of subsidies, or $21 billion, enhance fishing capacity and can lead to overfishing. Management subsidies aimed at monitoring, control, and stock assessments can help reduce overfishing, but their effectiveness varies between developed and developing countries. Lower levels of illegal fishing are associated with better managed fisheries, and reducing fuel subsidies could help generate more funding for management programs.
