概要

論文の詳細を見る
The foregoing sections of this rep o rt show the results of a biological, survey in which the principal fouling organisms as found in Tomioka Bay, Amakusa, were determined taxonomically, and their seasonal succession and general ecology were investigated. Methods employed include the use of panels of slate, glass-plates, glazed tiles, and bamboo cylinders suspended in the water. To study normal fouling the surface of panels was untreated purposely.船底に附着する生物の主髓をなすフヂツボ及びヒドロイデスは, 兩者共に干潮時と雖も水面上に露出すること無きが故に, 之を海岸に於て採集すること不可能にして, 專ら船底或は海中に浸漬せる物體に附着せしものより選定剥離して實驗に供せざるべからず。即ち生物の附着し易き試驗板を海中に浸漬し, 適當なる期間を經て之を引揚げ附着生物の採集を行ふ除り。
