Shifts in Mediterranean fish farming increase pressure on wild fish stocks

448_9938719983_cd8c5c1bb8_bFish farming in the Mediterranean has increasingly shifted from producing fish such as grey mullet, which are herbivores near the bottom of the food chain, to species such as sea bass, which are predators.

This ‘farming up’ the food chain requires wild fish to be caught to provide feed. A return to farming fish lower in the food chain would use marine resources more efficiently, a new study says.
