We determined the combined effects of salinity (10, 15, 20, 25, 27, 30 and 33 psu) and cold storage (4 ± 1°C) for 5, 14, 90 and 180 days for extending the lifespan of subitaneous eggs of the calanoid copepod Acartia sinjiensis. The hatching success rate of the eggs decreased with an increase in the cold storage period. The average proportion of viable A. sinjiensis eggs after 90 days was >40% except at a salinity of 10 psu. Eggs hatched at different times depending on storage and salinity. Specifically, >55% of the eggs stored for 14 days under the salinities of 25 and 30 psu and >45% of those stored for 90 days with salinities of 30 and 33 psu hatched. However, some eggs stored for 180 days hatched which only occurred at salinity 30 psu. These results can help optimize cold storage conditions to improve the viability of stored copepod eggs.

冷藏和盐度对中华猕猴桃（桡足类：Calanoida）卵孵化的影响

我们确定了盐度（10、15、20、25、27、30 和 33 psu）和冷藏（4 ± 1°C）5、14、90 和 180 天的综合效应，以延长calanoid桡足类Acartia sinjiensis . 卵的孵化成功率随着冷藏期的延长而降低。可行A的平均比例。 辛集除盐度为 10 psu 外，90 天后的鸡蛋>40%。根据储存和盐度，卵在不同时间孵化。具体而言，在 25 和 30 psu 的盐度下储存 14 天的卵中有 >55% 的卵孵化，在 30 和 33 psu 的盐度下储存 90 天的卵中有 >45% 的卵孵化。然而，一些储存了 180 天的卵孵化了，这些卵仅在盐度 30 psu 时发生。这些结果可以帮助优化冷藏条件，以提高储存桡足类卵的生存能力。
