The objective of this study was to determine the feasibility of raising carp on pig manure and coli, Brassica campestris. The use of pig feces as a source of fish food has been questioned by researchers (Hickling 1968). Coli was selected for dietary intake by fish since it is used for human consumption by the Indians of Guatemala. Commercial fish food (Silver Cup) was used for a control diet. These diets were both combined and used as a single source of food.
