A Length–Weight Relationship for Channel Catfish Grown under Commercial Conditions in Mississippi

A length-weight relationship was developed for channel catfish (Ictalurus punctatus), 13–67 cm total length, grown under commercial conditions in Mississippi. In total, 8,885 fish were sampled from ponds stocked at 11,100 to 19,800 fish/hectare. Predicted weight from total length is based on the equation log e (weight, g) = 0.27357209 + 0.25646117 cm – 0.003298348 cm2 + 0.0000184 cm3 (r 2 = 0.9885). This relationship is very similar to that found for pond-raised channel catfish in Kansas, but weights for pond-raised fish up to 55 cm total length were greater than those for wild channel catfish in Alabama.
