摘要
分别选取进口质量较好卤虫卵、进口质量较差卤虫卵、台湾产卤虫卵和天津产卤虫卵进行标准条件孵化、自然条件孵化及去壳卵孵化.结果发现,天津产卤虫卵,颜色、形状正常,每1 g卵数为19×104,孵化率最高,达94.0%.质量较差的进口卵,颜色、形状不太正常,每1 g卵数为35×104,孵化率最差.在标准和自然条件下,卤虫卵均在36h达最高孵化率,但标准条件下的孵化率高.去壳卵的孵化率最高,孵化24 h时,最高孵化率达96.8%比标准条件孵化时快近12 h.但去壳卵易结团或结块下沉,不易漂浮.
The experiment is to compare the incubation of four kind of eggs of Brine shrimp. The result shows that the hatching rate of the shell removed Sunshine brand Brine shrimp produced in Tianjin is the best under incubational, indoor or natural conditions, with the maximum hatching rate 94.0% . And the next is Phoen 2x, followed by Goldenfish, and the worst is Choice. The egg of four kind of Brine shrimp incubation reached maximum hatching rate in 36 h, but the shell removed egg of Brine shrimp incubatoin reached maximum hatching rate in 24 h, with the maximum hatching rate 96. 8% .
