According to the present invention, a shelter has a shelter unit with valleys orthogonal to the flow of water in one direction so as to prevent the injected feed from being swept away by the flowing water. A reinforcement plate having the shelter unit disposed in the lower portion thereof is arranged parallel to the flow of the water, thus preventing wastes of young shell from piling up.La présente invention concerne un abri, qui comporte une unité abri présentant des creux orthogonaux par rapport à lécoulement deau dans une direction, afin déviter que les aliments injectés soient emportés par le flux deau. Une plaque de renfort, au fond de laquelle lunité abri est installée, est placée parallèlement à lécoulement deau afin de prévenir laccumulation de déchets de jeunes coquilles.본 발명에 따른 쉘터는 일방향의 유수흐름과 직교되도록 쉘터유닛의 골이 형성되어 투입된 사료가 유수에 의해 쓸려 나가는 것을 방지할 수 있고, 쉘터유닛이 하측에 설치된 보강판이 유수흐름과 평행하도록 배치되어 치패의 배설물이 쌓이는 것을 방지하는 효과가 있다.
