Abstract

Graded and ungraded channel catfish (Ictalurus punctatus) fingerlings stocked in three partitioned floating cages were reared for 140 days during the summer, 1982. Fish were fed to satiation once daily with a commercial pelleted ration. At harvest, graded fish averaged 403 g and ungraded 362 g. Coefficients of variation indicated graded fish were more uniform in size and a significantly greater proportion of the graded fish were of salable size (> 340 g).
