Restoring fish stocks in the EU and UK to sustainable levels would provide significant economic benefits. According to the document, catching fish at maximum sustainable yield (MSY) would result in an additional 3.5 million tonnes of catch worth €3.2 billion annually, supporting over 100,000 jobs. While it would cost €10-12 billion to compensate fishermen during a 4 year moratorium, the investment would be recovered within 4.6 years. Maintaining fish stocks below MSY amounts to ongoing economic losses of over £2.7 billion per year and 100,000 jobs.
