Abstract

高知県水産試験場は水産庁委託研究「貧酸素水塊被害防止対策事業」において、浦の内湾の貧酸素化防止技術開発として潮汐ダムを取り上げ、潮汐ダム実用化のための基礎資料を得ることを目的に、平成3年度から6年度にわたり現地実験を実施した。本研究は、潮汐ダムの実用化の一環として、浦ノ内湾の湾口近くの出水枝湾に位置し、深浦漁業協同組合の所管するクルマエビ幼稚仔保育場の一部を改造して造成された模擬潮汐ダムにおいて、水産試験場との共同で平成6年度に調査研究したもので、ここでは特に噴流による底層のDO改善調査結果について述べる。

This study was carried out in 1994 as a chain program for putting the tidal dam to practical use. The experimentaldam was made by reconstructing a nursery facility for prawns in possession of Hukaura Fisheries CooperativeAssociation near the mouth of Uranouchi bay.The dissolved oxygen improvement effect of buoyant jet was examined as a factor of environment reformationby tidal dam. To identify the species of fish and shellfish living in the reservoir, they were caught at thereservoir gate when the tidal dam was demolished.The problems of the practical tidal dam was discussed. The tidal dam has several advantages. First it uses thetidal energy-an extremely stabilized natural energy. Second, it contributes to the environment improvement ofbay area. Besides, it can do much for developing the sightseeing and leisure facilities.
