摘要: 为了探究漂白粉在自然衰减情况下对近亲真宽水蚤各发育阶段的灭杀效果,在5℃和25℃条件下不同肥度的水体中进行了漂白粉对近亲真宽水蚤的毒性试验。试验结果表明,水肥度及温度是漂白粉的衰减影响因子,近亲真宽水蚤的卵、成体、桡足幼体和无节幼体对漂白粉(有效氯)浓度耐受性依次减弱,漂白粉对其灭杀浓度分别为32.000、3.200、1.000~3.200、1.000mg/L。因此,在水产养殖过程中,使用漂白粉灭杀近亲真宽水蚤时,其使用量应考虑近亲真宽水蚤不同的发育阶段及温度、水肥度对灭杀效果的影响。

Abstract: In order to assess the deratization effect of bleaching powder on Eurytemora affinis in different developmental stages under natural attenuation situation,a toxicity test of bleaching powder on Eurytemora affinis in water bodies with different fertility at 5℃ and 25℃ was carried out.The results showed that water fertility and temperature were the attenuation influencing factors of bleaching powder;the tolerated concentration to bleaching powder(available chlorine)of eggs(32.000 mg/L),adults(3.200 mg/L),copepods(1.000~3.200 mg/L)and nauplii(1.000 mg/L)of Eurytemora affinis exhibited a decreasing trend in turn.These results indicate that when bleaching powder is used to kill Eurytemora affinis,its dosage should be determined with the consideration of different developmental stages of Eurytemora affinis,water fertility and temperature.
