Protein/Energy Requirement of the Red Crawfish
Abstract
A study was conducted to determine the optimum protein to energy ratio for red crawfish (Procambarus clarkii). Six experimental diets were formulated which contained 20, 30, or 40% protein and 2500 or 3500 kcal/kg gross energy. Growth decreased as dietary energy increased in crawfish fed 20 and 30% dietary protein. Growth of crawfish fed 40% dietary protein decreased as dietary energy decreased. In general body protein decreased as dietary energy increased. Crawfish fed low energy (low fat) diets exhibited lower body fat. Also, body fat tended to decrease as dietary protein increased. Data indicated that dietary protein/ energy imbalances affected performance. In addition, 30% dietary protein and 2500 kcal/kg dietary energy appeared to be adequate for good growth and protein deposition.
