Etical fishing

with companies over-fishing and illegal operators pillaging the oceans, where do we turn for ethical insight on how to handle overfishing of our oceans. do we look for it in Eco labs that are providing sustainable fish? or do we turn to fish farms to solve the problem. i think that education would probably be in our best interest if we want to save fish from extinction. through education we can teach young and old what is happening with our oceans and what will be the end result if we do not do something.
