There are many schools of thought with fishing. Catch and kill what you are going to eat, catch and kill all, catch and kill selectively.... Fish is not an unlimited resource of course. We should all practice conservation when we can. In my opinion, based on species populations, more reproductive cycles for more rare fish before harvest should be stressed regardless. For species that are popular and numerous, we still need to practice conservation. That fish should have helped or reproduces at least 2-4 times. This would help our oceans for sure to recover. On the comercial side, rod and reel is the only way to go.
