PURPOSE:To improve adhesion of an administration substance to a solid feed and to effectively prevent the substance from dissolving or dispersing into water by adding the administration substance such as a medicine to the solid feed for fish and shells in the presence of a specified spreading agent. CONSTITUTION:To a solid feed for fish and shells produced in advance, an administration substance such as a medicine or a medicine for promoting nutrition is added in the presence of one or more spreading agents selected from sodium polyacrylate, sodium alginate and CMC. This invention enables a suitable selection of a necessary kind of an administration substance corresponding to various conditions, e.g. a state of growth of fish and shells or a state of disease outbreak and enables direct administration of the feed immediately after adding a required amount of the administration substance to the feed at a feeding spot, etc. |
