“The aquafeed manufacturing industry is widely recognized as one of the fastest expanding food industries in the world. Fish meal is the

main protein source in aquafeed, but supply is limited, which means that alternative sources must be used. From a processing point of view, extrusion is the most efficient way of turning plant protein into fish feed. Twin screw extruders offer a definite advantage in this.The goal for production of aquatic feed is to manufacture a nutritionally complete product that achieves the desired product characteristics.

While all aspects of the process are important, a number of the unit operations of the manufacturing process are critical to achieve

this goal.
