FEED USING PEELED KRILL AS THE STARTING MATERIAL AND METHOD OF PREVENTING DECREASE IN FISH GROWTH RATE BY USING THE SAME

摘要

It is intended to provide a substitute for fish meal that has been used as a protein source in feeds for cultured fishes. It is also intended to effectively utilize krill as a feed material which has been employed as a feed material only for limited purposes. Specifically, a feed using krill as a part or the whole of the protein source, characterized in that peeled krill are used as the krill. It is preferable that the fluorine content of the krill has been lowered to 250 mg/kg or less on the basis of dry weight by peeling. A method of preventing a decrease in the growth rate of fish by using krill as a starting material of a feed characterized in that peeled krill are employed as the protein source of the feed for cultured fish.
