To solve problems of rather difficult fixation and growth of animals and vegetables on the surface of concrete or wood to necessitate a long time for the fixing and proliferation and lower the efficiency for the fixing and growth of especially crustaceans, arthropods and/or shellfish, mollusks and/or coelenterates and/or protochordates.

The invention provides a simple method for producing a construction for undersea installation to activate the fixation and growth of crustaceans, arthropods and/or shellfish, mollusks and/or coelenterates and/or protochordates and promote the growth of the marine animals, effective for the aquaculture of the animals, contributing for the activation of aquatic resources, and enabling the reuse of the used waste as a weed-controlling material. The method comprises the use of a structure for undersea installation obtained by packing vegetable materials such as forestry products containing wood chips produced from thinned wood or construction and demolition waste or cereal by-products in a net bag.
