Channel catfish, Ictalurus punctatus, from seven geographical locations and two inter-population crosses were raised under the same environmental conditions from the time of spawning until they were harvested at the Auburn University Fisheries Research Unit from June until November, 1971. Nine morphometric measurements were taken on ten fish from each strain. The strain means for total length were compared statistically by a one-way analysis of variance and by Duncan's new multiple range test. An analysis of covariance was used to correct for differences in total length on each of the other measurements. The correlation coefficients between total length and the other measurements were also determined. Highly significant differences between the strains were found for all of the measurements except caudal peduncle width. Possible commercial significance of the morphometric differences is also discussed.
