The present invention addresses the problem of providing a bivalve farming raft which: can be discarded without being burned; does not use foamed styrol, which is often discarded to drift in the sea; is less likely to cause stress concentration due to external force of ocean waves and tidal current and therefore is less likely to be deformed (e.g., twisted), damaged, and swept away; does not greatly sway due to ocean waves and therefore enables shells being farmed to grow well; has a simple structure; has high durability; and can have a prolonged lifetime. The present invention also addresses the problem of providing a bivalve farming method. The problem can be solved by: a bivalve farming raft for farming bivalves which is provided with a body from which two or more suspended ropes for farming bivalves can be suspended, the body itself having a greater effective buoyancy when floating in water than the total weight-in-water of the plurality of suspended ropes which are directly bound to and suspended from the body; and a bivalve farming method using the raft.
