A length–weight relationship was developed for pond‐raised hybrid catfish fingerlings, Ictalurus punctatus × Ictalurus furcatus . A total of 4663 fish were sampled ranging from 20 to 240 mm total length. Predicted weight (g) from length (mm) is based on the equation: Y = 0.000017311 X 2.868474309 ( r 2 = 0.996) where Y is the estimated individual fish weight and X is measured total length. The predicted values generated by this model differ from, but follow the same general trends seen with channel catfish, I. punctatus , fingerlings and can be used as a baseline for the development of a length–weight table for hybrid catfish fingerling production.
