重金属离子除去装置在中国对虾育苗生产中的应用

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％。

EXPANDED APPLICATION OF HEAVY METALION REMOVAL DEVICE IN SEEDING REARING OF Penaeus chinensis ON A PRODUCTIVE SCALE

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.
