Why Are Wild Caught Fisheries Important?
One of the most fundamental services the ocean provides people is the provision of seafood. It helps to meet the basic nutritional needs of over half of the world’s population. Over one billion people rely on fish as a daily source of protein. 87% of the world’s wild caught fisheries are fully exploited, overexploited or depleted.

What Does This Score Mean?
This sub-goal assesses the amount of wild-caught seafood that can be sustainably harvested. The population biomass (the weight of fish in the ocean) of each landed stock is compared to the biomass that can deliver the stock’s maximum sustainable yield. The geometric mean of the values for all stocks in an area, each weighted by its proportional contribution to the total catch, gives the overall fisheries stock status for that area.
The goal target is for regions to have their biomass of wild stocks within 5% of the amount that can sustainably deliver the maximum sustainable yield. Regions are penalized for both under- or over-harvesting. Penalties for under-harvesting are half as large as for over-harvesting.
The current score indicates that most regions are significantly below their sustainable target values. Some regions are jeopardizing their future landings with unsustainable yields, while others are not producing as much wild-caught seafood as they could.
