Kind Code: A1 A metal lattice-shaped member, which is large enough to cover the entire target fish reef or a portion of a fish reef inhabiting the aquatic organisms to be raised, and which is provided with a doorway (4) having an upwardly open door (3) in a part thereof. In this case, the gap between the lattices of the cover is such that a human fist cannot enter, and the door has a weight that cannot be opened manually. [Selection diagram] Fig. 1
