UNEP calculates that investing $110 billion over the coming years in strengthened fisheries management – including the establishment of MPAs, the decommissioning and reduction of fleet capacity, and retraining of workers – will allow the planet’s fisheries to recover. Such an investment, backed by policy measures, would result in an increase in catch levels from 80 million tons now to 90 million tons in 2050, following an initial decline between now and 2020.
