Potential of Fish Meal Rendered From Asian Carp to Support Aquaculture Feed Manufacturing
To determine the suitability of Asian carp to support aquafeed manufacturing, we evaluated seasonal and geographical variation in the body composition of Asian carp, performed standard digestibility studies with sunshine bass and rainbow trout, and compared production performance of carp FM to traditional menhaden FM.
Results indicate slight geographical and seasonal variation in body composition, though both species represent protein-dense raw materials suitable for FM production. Carp FM is highly digestible, although slightly less digestible than menhaden FM. Production performance of carp FM was similar to menhaden FM in practical diets. Overall, Asian carp FM appears to be a highly-digestible, nutrient-dense ingredient suitable for aquafeed production.
