Top Southern Hardshell Clam Fishing Countries

The Southern Hardshell Clam (Mercenaria campechiensis), a robust bivalve native to the Gulf of Mexico and the southern Atlantic coasts of North America, is prized for its firm texture and mild flavor. This species thrives in sandy and muddy coastal habitats, where it is harvested both commercially and recreationally. The top countries engaged in Southern Hardshell Clam fishing are the United States and Mexico, with the U.S.—particularly the Gulf Coast states like Florida, Texas, and Louisiana—leading in both wild harvest and aquaculture production. Mexico also supports a significant clam fishery, especially along its Gulf coastline. The industry is vital for local economies, supporting jobs in harvesting, processing, and distribution, while also facing challenges related to habitat degradation and water quality, which are addressed through management and conservation efforts.
