Since 1966, a study has been conducted in earthen ponds of the Auburn University Agricultural Experiment Station, Auburn, Alabama, to evaluate the potential of suspended cages for culturing catfish, from fingerlings to marketable size, and to develop the basic techniques necessary for the extension of the culture. This paper presents the developments obtained in the study. Experiments on effects of stocking density per volume of cage, cage positioning relative to the environment and to other cages, and cage mesh size on production are discussed.
