- Most species of crabs are caught in pots or traps that are designed to reduce bycatch and habitat damage.
- Red and blue king crabs, harvested for their legs, come primarily from a poorly managed Russian fishery — look for U.S. king crabs instead.
- Alaskan snow crabs from the Bering Sea have recovered from overfishing and the fishery is well-managed and closely monitored.
- Although blue crabs (hardshell and softshell) can generally withstand heavy fishing, habitat degradation in the Chesapeake Bay and bycatch in Gulf of Mexico shrimp fisheries continue to be concerns.
- Approximately 20% of Chesapeake blue crabs are caught on hookless "trot lines", which have the added benefit of zero bycatch since the bait is tied directly to the line. These are considered an "Eco-Best" if you can find them in the market.
