Catfish farms suffered great losses when using polyculture with Bighead Carp, a species that turned out to be a good host for the crustacean parasite Lernaea cyprinacea. This parasite is also known to affect salmonids and eels.

The market for live Bighead Carp (Hypophthalmichthys nobilis) in the United States is limited (the typical consumer will buy only enough fish for the current day’s meal) and easily saturated. However, some vendors can sell only 100 to 500 pounds of bighead each day

Additionally, bighead carp (Hypophthalmichthys nobilis) can be an important source of revenue for catfish farmers during times of low catfish prices. In polyculture with catfish, bighead carp provided additional revenues of $95 to $391 per acre at market prices of $0.25 to $0.70 per pound, respectively. However bighead raised alone, the break-even prices above variable and total costs assuming $0.28 and $0.52 per pound, respectively.

The net benefit of stocking Bighead Carp (Hypophthalmichthys nobilis) with catfish was substantially higher. Net benefits ranged from $1,628 to $2,743 annually from a 6-ha (15-acre) pond.
