On a staple diet supplemented with bloodworms and brine shrimp, a young channel catfish can grow as much as an inch a month. Percent frequency of occurrence (O i), mean percent frequency by number (MN i) and prey-specific abundance (P i) were calculated. Within certain limits, catfish grow faster as the protein content of their diet is increased. But they also feed at the surface.
