PROBLEM TO BE SOLVED: To provide an aquatic resource-activating structure improving insufficiency of vegetable nutrient resources such as fallen leaves, foliage, fallen trees and the like flowing into the sea from forest lands via rivers as a result of development of revetment, dikes and the like of the rivers which is recently pointed out as one of reasons for such a phenomenon called "rocky-shore denudation" in which seaweeds are reduced and thus undersea rocky stretch or the like are barely exposed, especially in the coastal area along the Sea of Japan in Western Japan.SOLUTION: The aquatic resource-activating structure is produced by binding a material prepared by mixing a mixture of vegetable materials such as forest products consisting mainly of wood chips containing wood including at least thinned wood, and cereal by-products, with marine product materials except a shell or Cephalopoda material via a binding agent to solidify the bound material. The aquatic resource-activating structure inexpensively and greatly facilitating fixation of seaweeds, effective for aquaculture of seaweeds themselves, contributing to activation of fishery resources and thereby substantially contributing to industries, is obtained by an aquatic resource-activating method which is simple and includes using the aquatic resource-activating structure.COPYRIGHT: (C)2013,JPO&INPIT【課題】近年、特に北日本の日本海側沿岸地域では、海藻が減少して海底の岩場等がむき出しになる所謂磯焼けが問題となっている。この原因のひとつとして、河川の護岸、堤防等の整備によって山林から河川を経由して流入する落葉、枝葉、倒木等の植物性の栄養源の不足が挙げられている。【解決手段】少なくとも間伐材を含む木質を原料とする木材チップを主材料として含む林産物や穀類副産物などの植物性材料の混合物と、貝類又は頭足類に由来する材料を除く水産物材料を混成したものを結着剤により結着固化して形成したされてなる水産資源賦活用構造体を用いるという簡便な方法によって、安価に非常に海藻類の定着が容易く海藻自身の養殖漁業として有効であり、さらに漁業資源の賦活に寄与する水産資源賦活用構造体を得ることが出来、以って産業に多大なる貢献をする事が出来るものである。【選択図】図1
