Bighead Carp

چکیده
In the United States, bighead are polycultured with channel catfish in approximately 5,100 acres of earthen ponds, including an estimated 4,000 acres in Arkansas, 500 in Mississippi, and 600 in Alabama. Bighead are an important source of additional income that, at times of low catfish prices, has kept some fish farmers in business. The primary market is to live-haulers who sell to specialty markets in large cities. The current U.S. market is limited and easily saturated. Wide fluctuations in price and unique marketing requirements for bighead have prompted farmers to seek alternative markets.
