The gulf sustains 40 percent of the nation's commercial fish catch by volume and one-third of the nation's main sport-fishing activity. Over 90 percent of the fishing stocks, from shrimp to flounder, rely on bays and coastal wetlands to spawn, nurse, and rear. Today, these estuarine and coastal areas are being overtaken by some of the nation's worst extremes in pollution and habitat loss.estuariespollutionshellfishrunoffred tidesdevelopment projectshabitat destructionArticle
