摘要
本文叙述了在室内挂制条件下,温度对黑龙江河兰蛤受精卵孵化和幼体生长发育的影响。发现兰蛤受精卵孵化和妨体生长发育的适宜水温为21.5～25.4℃,其中以24.5℃为最隹。在此温度范围内,受精卵孵化发育形成D形幼体,幼体生长迅速,成活率高达80％以上。
Effects of temqerature on hatching of zygotes and growth of sqats of the potamocorbula amurensis have been investigated. The results obtained showed that the suitable development temperatures range from 21.5℃ to 25.4℃. In this range of temperatures the spats graw rapidly aud the survival rate reaches above 80%, and the optimum temperature is 24.5C、
