<；P>；PROBLEM TO BE SOLVED: To provide a fish farming feed mixture and the like using bamboo and suitable for practical use as a sample additive of saltwater fish. <；P>；SOLUTION: A method for producing the fish farming feed mixture includes: a step of obtaining bamboo powder by pulverizing bamboo, a step of drying the bamboo powder, and a step of adding fermentative bacteria to the dried bamboo powder to ferment the powder. Since the bamboo powder thus obtained by crushing not bamboo grass but bamboo is used, a supply amount is secured, and at the same time, sterilizing power is suppressed so as to add fermentative bacteria such as lactic acid bacteria, and it is possible to demonstrate favorable characteristics as the fish farming feed mixture, such as an intestinal function regulating action. The average particle diameter of the bamboo powder is preferably 40-500 &mu；m, and the moisture percentage of the bamboo powder is preferably 30-50%. As fermentative bacteria, lactic acid bacteria or bifidobacteria are suitably used. <；P>；COPYRIGHT: (C)2011,JPO&INPIT
