September’s Fish of the Month is domestic farmed catfish.
There are 39 known species of catfish in North America, only one of which we farm commercially: the channel catfish. In the wild, channel catfish can live up to 40 years and grow to weigh nearly 60 pounds. They’re a freshwater species, thriving in clear water habitats with coarse sand or gravel bottoms. Channel catfish are omnivores, which mean they eat both plant food (such as algae and seeds) and animal food (such as snails and crawfish). They detect their food visually, but also have taste buds all over their bodies!
Channel catfish is one of the most commonly farmed fish species in the United States, generating the most volume and revenue of all domestically farmed fish. It’s an important industry in the southeastern U.S., particularly in Mississippi, Louisiana, Alabama and Arkansas. Channel catfish are farmed in closed, inland ponds. Those are a much more environmentally friendly alternative to farming fish in the open ocean, where pollution, escape and disease transfer often occur. Plus, because channel catfish are omnivores, they’re fed a primarily vegetarian diet instead of fishmeal – thereby minimizing the need to catch wild fish to feed farmed fish.
