摘要
自行研制的高分子吸附剂装置,在两处中等规模的中国对虾育苗场进行了应用实验。结果表明,在其他条件一致的情况下,应用装置与使用自然海水育苗对比,卵子的孵化率平均提高11.8%,无节幼体到蚤状幼体变态率平均提高10.2%;应用装置与使用EDTA(2.0mg/L)比较,卵子的孵化率平均提高7.5%,无节幼体到蚤状幼体的变态率平均提高3.6%。
This paper summarizes the results of expanded applicat ion of heavy metal ionremoval device used in rearing seedlings of Penaeus chinensis on a productive scale as follows:(1) Under same conditions, use of the device increases by 1 1. 8% the average egg hatching rateand increases by 10. 2% the average metamorphosis rate from nauplii to protozoea (comparedwith that in natural seawater); increases by 7. 5% the average egg hatching rate and increases by3. 6% the metamorphosis rate as compared to using 2. 0 mg/L EDTA in the rearing system. Thedevice can effectively remove toxic heavy metal ions from culture seawater.
