Results were as followo : (1) The oyster larvae did not show skototaxis. (2) The oyster larvae set on the collector when their shell height were about 300 μ.. (3) The spats grew in shell height about 450-500 μ a day. (4) After 24 hours the sorviving spats decreased in number to 70% of that of first day and to 13% after 48 hours. (5) Most of the larvae set on the collector during the tidal current is there. (6) Ratio of shell height to shell length, while larger than 1 in fuil grown plankton larvae, become <1 after setting, but in a while the height grows faster again until the form of adult is attained.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1. 自然の状態では larvaの附着は,走暗性に依るよりも,物理的理由に依って附着する場合が多いと考えられる。2. 附着直後の Spat の大きさは,殼高が300μ位,或は此れよりもわずかに小さいものと思われる。3.附着後数日間は Spat の殻高が1日当り470μ前後成長する。4.
