The present invention uses a waste fungus bed in which chip material such as sawdust is made into one lump with hyphae that can be installed at a very low cost and is safe for navigating ships, etc. It is to develop and provide fish feeding methods using fungal beds. [Solution] Using a waste fungus bed (1) after cultivating white rot fungi, by substituting the waste fungus bed in the sea, living organisms of the family Funakidae are settled and grown, and the organisms are fed into fish food. The waste fungus bed is placed in a cage-like fishing reef (Y) submerged in the sea, and the waste fungus bed, wood pieces, or the waste fungus bed and wood pieces are submerged in the sea It is press-fitted together with water into a fish-shaped reef, the surface of the waste fungus bed is coated with natural rubber (2), and the waste fungus bed (1) is formed by solidifying sawdust, Feeding fish using a waste fungus bed characterized in that the waste fungus bed (1) is inserted into a spider-like fishing reef (Y) submerged in the sea. Method. [Selection] Figure 3【課題】この発明は、極めて安価で設置でき、しかも航行する船舶等にも安全なオガ粉等のチップ材を菌糸により一つの塊にした廃菌床を用い、魚類の与餌効果の高い廃菌床を利用した魚類の与餌方法を開発・提供する事にある。【解決手段】白色腐朽菌を栽培した後の廃菌床（１）を用い、該廃菌床を海中に沈設することでフナクイムシカ科の生物を着棲・生育させ、該生物を魚類の餌とすることを特徴し、前記廃菌床を、海中に沈設した籠状の漁礁（Ｙ）内に入れ，前記廃菌床、木片、あるいは前記廃菌床と木片とを、海中に沈設した籠状の漁礁内に水と共に圧入し、前記廃菌床の表面を、天然ゴム（２）でコーティングし、前記廃菌床（１）は、オガ粉を固めて構成されたものであり、外周に菌糸（Ｘ）でまとわれ、さらに、前記廃菌床（１）を、海中に沈設した籠状の漁礁（Ｙ）内に挿入することを特徴とする廃菌床を利用した魚類の与餌方法。【選択図】 図３
