Farming doesn’t always mean tilling the ground for crops. In the flat valley along the Mississippi River, in a distinctive region of northwestern Mississippi referred to as “the Delta,” rich soils do support agriculture. But the flat land and abundant groundwater are also suited to aquaculture. Aquaculture simply means cultivating aquatic plants or fish for food. In this part of Mississippi, it means catfish farming.
Catfish are raised in Arkansas and Alabama, but Mississippi has led the nation in catfish production since the 1980s. The farm-raised catfish eat high-protein food pellets made of soybeans, corn, wheat, vitamins, and minerals. The pellets float on top of the water, so the fish don’t eat like wild bottom-feeding catfish do. The result is healthier fish with a cleaner, milder taste.
The Mississippi River meanders down the left side of these Landsat images. Green indicates vegetation: Bright green shapes are cropland, and darker green shades are forests. Surface water is dark blue. Besides the Mississippi, other streams and oxbow lakes are scattered across the region. The catfish ponds are the distinctive blue squares and rectangles among the cropland. The washed-out pink areas are harvested fields.
