Effects of feed protein concentration and feeding rate combinations on quality of pond water and effluent in channel catfish culture Academic Article uri icon

abstract

  • Abstract Three feeds with different concentrations of crude protein were applied to 400 m2 channel catfish ponds at the Auburn University Fisheries Research Unit. Fish were fed to satiation with the 28% crude protein feed: the other two diets (32% and 36% crude protein) were applied in amounts calculated to provide the same crude protein input as for the 28% crude protein diet treatment. Using this practice, feed application decreased as feed crude protein increased; likewise, phosphorus and organic matter loads to the ponds decreased …
