Biological Evaluation Of Aquatic Plants As Potential Ingredients In Supplemental Feeds For Channel Catfish
A series of feeding trials were conducted in raceway-type aquariums with semi-purified diets for the purpose of biologically evaluating aquatic plants as diet ingredients for channel catfish. A protein concentrate extracted from water hyacinth was compared with casein for protein efficiency ratio (PER) with channel catfish fingerlings. The possibility that growth factors may be contributed by small amounts of dehydrated aquatic plant meal in the diet was tested by adding 5 or 10% water hyacinth meal or alfalfa meal to vitamin-free and vitamin-sufficient purified diets and to commercial-...
