Blue Crabs mature early and carry their eggs for a short period
of time, making them more resilient to fishing pressure than
other crab species. Abundance varies throughout their range.
Habitat degradation in the Chesapeake Bay and Gulf of Mexico
threaten Blue Crabs in those regions. This fish may have high
levels of mercury and PCBs that could pose a health risk to
adults and children. More mercury and contaminant info here.
