The effect of low salinity levels on byssal re‐attachment behavior in Pteria penguin juveniles was observed in the laboratory. Juvenile pearl oysters were submerged in seawater blended to 8.0, 12.0, 16.0, 20.0, 24.0, 28.0, and 32.0 salinity levels for a period of 48 hr. The sub‐lethal salinity level was greater than 20.0 psu. Although salinity levels of 20.0 and 24.0 psu did not affect the oyster survival, the observed byssogenesis activity was significantly reduced and locomotion activity was delayed. Description of the effects of low salinity levels on the byssal re‐attachment behavior of P. penguin juveniles provides a foundation for the design of more complex experiments and approaches to further the exploration and development of improved pearl production techniques.

翅虾牡蛎Pteria企鹅的再附着行为对低盐度的响应

在实验室中观察到低盐度水平对Pteria企鹅幼体的再附着行为的影响。将幼年珍珠牡蛎浸入盐度为8.0、12.0、16.0、20.0、24.0、28.0和32.0的海水中48小时。亚致死盐度水平大于20.0 psu。尽管盐度为20.0 psu和24.0 psu不会影响牡蛎的存活，但是观察到的副代发生活性显着降低，运动活动被延迟。低盐度对企鹅幼体的再附着行为的影响的描述为更复杂的实验和方法的设计奠定了基础，以进一步探索和开发改进的珍珠生产技术。
