The present invention relates to a double tube type shelter for cultivating sea cucumber, and comprises: a separate cage frame installed in the seabed; an outer fixed frame fixed to the cage frame; an inner shelter put in the outer fixed frame; an outer net for preventing small sea cucumbers present inside the inner shelter from escaping to the outside, and a funnel for blocking an entrance of the shelter. The shelter of the present invention is constituted in an assembly structure in the cage frame and installed in the seabed, and thus the facility is scarcely destroyed by strong sea waves, thereby increasing the survival rate of cultured organisms such as sea cucumbers, and allowing the organisms to absorb organic matters contained in the mud of the seabed and thus costing less feedstuff. Further, the shelter of the present invention is less influenced by the variation of water temperature, such as the high water temperature during the summer season and the low water temperature during the winter season, and can cultivate sea cucumbers in a condition in which the inhabited environment necessary for the growth of sea cucumbers is almost similar to that in the natural state, thereby securing fishery resources and thus significantly contributing to promotion of fisheries. |
