About this Fishery

Blue crab is found in coastal waters in the western Atlantic from Nova Scotia to northern Argentina. This fishery operates in Louisiana state waters in the Gulf of Mexico, though more than half of the Louisiana blue crab is harvested in two areas — Lake Pontchartrain basin and Terrebonne basin.

Around 3,000 fishers target blue crab in baited traps. The fishery operates the entire year but typically has the highest landings from May through to August.

In 2005 Hurricane Katrina and Hurricane Rita caused devastation to fishing infrastructure, vessels and gear, leading to a substantial reduction in commercial fishing. However, landings remained high, indicating the abundance of blue crabs in the area.
