Indicator 14.4.1 - Proportion of fish stocks within biologically sustainable levels

This indicator measures the sustainability of the world's marine capture fisheries by their abundance. A fish stock of which abundance is at or greater than the level, that can produce the maximum sustainable yield (MSY) is classified as biologically sustainable. In contrast, when abundance falls below the MSY level, the stock is considered biologically unsustainable. The indicator will measure progress towards SDG Target 14.4.
