PROBLEM TO BE SOLVED: To provide a shellfish culture apparatus capable of capturing spawn and floating larvae of shellfish to rear them in conditions and states close to a habitat at a low cost and preventing shellfish in culture from escaping or flowing out on waves of the sea surface or water surface.SOLUTION: A shellfish culture apparatus 1 includes: a rearing net part 2 stretched near the sea bottom or the water bottom; a capture/protection net part 3 connected on one end side to the rearing net part and laid over to cover the top of the rearing net part; a first support member 4 supporting the other end side of the capture/protection net part in a vertically movable manner; and a buoyant body 6 mounted to the other end side of the capture/protection net part to vertically move the other end side of the capture/protection net part according to the vertical movement of the sea surface or the water surface. Green laver is stuck to the rearing net part and the capture/protection net part, and the other end side of the capture/protection net part is vertically moved in the spawning period of shellfish to capture spawn or floating larvae. After captured, the spawn or floating larvae are held and reared between the capture/protection net part and the rearing net part. |
