21. Red Snapper
> Reason to avoid: Declining populations, negative habitat impact
> Farmed or wild-caught: Wild-caught
Perhaps the Gulf of Mexico’s most famous fish, red snapper has been seriously overfished, and fishery managers allow a catch that’s 50% higher than recommended. In addition, bycatch — of sharks, groupers, porgies, and other species — accounts for a staggering 44% of the total taken.
