another major hurdle:fishmeal

But even fully contained facilities still contend with another major hurdle:fishmeal.About 10% of the seafood caught globally is used to feed animals,including carnivorous farmed fish.Researchers are working on fish feed made of insects and plant-based proteins,but for now many inland fish farms are connected to overfishing.All these obstacles can make sustainable aquaculture feel a long way off,but innovative farmers are finding new ways to responsibly farm the seas.
