Is Farmed Better Than Wild?

Farm trimp often destroys mangroves and other coastal habitats, usually in southeast asia. They use a lot of pasticides and antibiotics. Worker exploitation is a huge problem. I think it would be best for me to buy the small stuff, rit like anchovies. That will be more sustain eating farmed shellfish, eating farmed seaweed. Instead of eating these top preditors like tunas, we could be eating sardines and anchovies.
