This is designed to artificially underwater marine organisms to the composition of the spawning grounds or formatting Chapter Sea Forest is a facility to facility relates to a box-Sung haejungrim seconds. This is designed as a box-Sung Sea Forest haejungrim seconds of the square cube shape, seaweed seed the seedling algae is a binding framework that meshes seaweed nurseries built framework that is built in the mesh frame a fixed frame that is built in the seaweed nurseries built home latches that secure the mesh frame and the seaweed nurseries built framework including the anchor bolt that secures the fixed peg haejungrim second fixed ropes and fixing the haejungrim seconds leading holes provided in the surface of the second sides haejungrim and by forming the second inner space haejungrim the haejungrim second inner space 54 is formed by placing the stone and in the space, doeyeo algae enlarged to form an area, algae spores released during seed maturation and reproduction is provided to facilitate mounting a new gijilreul and a weight per unit area is high, it is characterized in that the structure can be maintained securely from the storm. Further, a production process and production cost savings and simplification of the simplification of the structure of the mesh part of the fixed frame. There is an effect to protect the algae from the installation to the fence pirate biological networks and leading holmang the subject innovation (haejungrim second). In addition, it is effective to smooth the flow of sea water leading to the hole and increases the amount of oxygen supplied to the installation. Further, the present invention is to endure, and the wave field in a variety of structural stability, and the effect that can withstand a variety of environmental pollution, sea woods has the effect of creating an.본 고안은 수중에 인공적으로 수산생물의 산란장이나 서식장을 조성하기 위하여 시설하는 시설물인 바다숲 조성용 상자형 해중림초에 관한 것이다.본 고안은,정사각육면체형상의 바다숲 조성용 상자형 해중림초로서,해조류종묘상기 해조류종묘가 결착되는 메쉬틀상기 메쉬틀이 내장되는 해조류종묘내장틀상기 해
