The commercial harvest of farm-raised seafood in the ocean
Sustainable mariculture supports food provisioning needs through practices that can be maintained over the long term. This includes not compromising the water quality in the farmed area and not relying on wild populations to feed or replenish the cultivated species. Some mariculture practices, although they do not compromise future harvests, may impact the delivery of other goals through habitat destruction and accidental release of non-native species. These factors do not affect the sustainability of mariculture, but their impact upon the sustainability of other goals is captured as pressures when assessing such goals. The Israeli Mediterranean assessment Mariculture sub-goal uses the official reference point of 8,000 tons of fish harvested by year 2020. The new reference point assumes that production is driven by socially-related factors such as economic demand, coastal access, and infrastructure availability.
About this score

A high score can mean that a country is sustainably harvesting as close to the maximum amount of farmed fish and seafood as possible based on its own 
potential. A low score can indicate one of two things – that seafood is being farmed in an unsustainable manner or that regions are not maximizing their potential to farm fish and other marine animals in their coastal territory.

The current score suggests both the potential for fish farming is not maximized and that the current practice can be managed more sustainably.
