METHOD FOR SUPPLYING ARTIFICIAL FEED FOR CULTURING LARVAL SEA URCHIN

摘要

PURPOSE:To increase places of feeding to a larval sea urchin and reduce the residual feed by coating both surfaces of a substrate provided with many holes having a specified diameter and interval and the interiors of holes with an artificial feed for culturing the larval sea urchin, drying and solidifying the coated feed and supplying the feed thereto. CONSTITUTION:This method for supplying an artificial feed to a larval sea urchin is to coat both surfaces of a substrate provided with holes having 0.5-3.0mm diameter at an interval of 2-50 times the diameter and the interiors of the holes with an artificial feed for culturing the larval sea urchin, dry and solidify the coated artificial feed and supply the feed thereto. The resultant feed is good in feeding properties without deteriorating the survival ratio of the larval sea urchin.
