【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。更多还原

【Abstract】 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、更多还原
