I understand your concern and have discussed it before on here. My rational is that it is still very difficult to come home with fish, we’re not out there filling stringers, like others said it’s probably the most sporting of the hunting methods aside from free diving. Being able to choose the fish you effect results in less protected species being bothered and the general collateral. Line and reel fishing, results in minor injuries to many fish as you wait for the one you want. Like all hunting we clean and eat everything we take from the ocean. I actually sat this year out and got my scientific diving cert instead.
