Abstract
The tenacity of oyster spats in air was examined under different temperature and humidity, as this kind of nature of the animal has a much important relationship to the transportation of them in the distance.
At about 25-30°C a greater part of oyster spats died within 3 days even if at any humidity. When temperature in experiment falls below that in room, the majority of oyster spats could live longer than 4 days under high humidity which is much effective to prolong the tenacity of spats. The higher humidity becomes in the atmosphere, the much more water a spat seems to contain within. It is necessary to sustain W/Tθ×100>7 in order to keep up the survival rate more than 80%.
