PROBLEM TO BE SOLVED: To provide a culture method in which a culture substrate and a bivalve never separate unintendedly, and water permeability is maintained well, thereby causing no adverse effect in the growth and survival of infaunal bivalves when culturing the infaunal bivalves in the sea by hanging.SOLUTION: The infaunal bivalves 7 and the particulate culture substrates 5 are accommodated in a flexible net bag 2 that has a mesh size to prevent them from flowing out, the net bag 2 is accommodated in a rearing container 3 that has a mesh size to prevent the bag 2 from flowing out, and the rearing container 3 is hung in the sea.【課題】海中に埋在性二枚貝を垂下養殖するに際して、養殖基質と二枚貝が不用意に分離してしまうことがなく、しかも、通水性を良好に維持して埋在性二枚貝の成長や生残に悪影響が生養殖方法を提供する。【解決手段】埋在性二枚貝７と、粒状の養殖基質５とを、それらが流出しない目合いを有し且つ可撓性を有する網袋２に収容し、網袋２を、網袋２が流出しない目合いを有する飼育容器３に収容し、飼育容器３を海中に垂下する。【選択図】図１
