Grabowski, T.B., J.J. Isely, and R.R. Weller. 2004. Age and growth of flathead catfish, Pylodictis olivaris Rafinesque, in the Altamaha River, Georgia. Journal of Freshwater Ecology 19:411-417
Flathead catfish were introduced to the Altamaha River system, Georgia in the 1970’s. We determined the length-weight relationship, Von Bertalanffy growth parameters, and back calculated lengths by examining the sagittal otoliths of 331 individuals captured from this population. We found that there were no sex related differences in length weight relationship or Von Bertalanffy growth parameters. Flathead catfish in the Altamaha River system grow at about the same rate as individuals in other introduced populations.
