I prefer eating reef fish to ahi. Shoreline fisher people like me have a far greater impact on fish and shellfish life than aquarium collectors. My guess is that oxybenzone has a far greater impact on reef life than the collectors. I would guess that the recreational and tourist boat industries are far more distructive of ocean life that aquarium fishers. 

So rather than bully a small identifiable group no matter how disagreeable their practices, let's step back and control all us culprits.
