| 分析了不同浓度印染污水对银鲫(Carassiu sauratus)的生殖相关指标和金属硫蛋白(MT)的影响。设计1个对照组和2个试验组,对照组采用天然的水库水,试验组分别用浓度为0.1%和0.2%的印染污水养殖银鲫,每组3个平行,每个平行随机放入50尾银鲫,试验期为4周。结果表明,养殖4周后,0.1%印染污水组银鲫的肝体指数和血清卵黄蛋白原(VTG)水平显著上升(P<0.05),0.2%印染污水组银鲫的血清VTG水平显著低于对照组(P<0.05),印染污水对银鲫性腺指数没有影响。0.1%印染污水组银鲫在第2、3、4周,肝脏MT水平均显著高于对照组(P<0.05),0.2%印染污水组银鲫肝脏MT水平在第3周时显著升高(P<0.05),印染污水对银鲫肾脏MT水平没有影响(P>0.05);表明印染污水能够影响银鲫繁殖功能和组织MT的水平。 |

| The effect of printing-dying sewage on reproduction indexes and metallothionein(MT) level in Carassius auratus was analyzed. A control group and 2 the treatment group were devised，with three parallels for each group，50 fish per parallel. The control group was cultivated in pool water，while treatment groups were cultivated in pool water with printing-dying sewage with concentration of 0. 1%，0. 2% respectively. The test lasted for 4 weeks.The result indicated that vitellogenin (VTG) content and liver somatic index(LSI)of 0.1% group were significantly higher than that of control group(P<0.05)after 4 weeks，while VTG content of 0.2% group was significantly lower than that of control group(P<0.05)after 4 weeks.The printing-dying sewage had no significant effect on gonadogomatic index(GSI ).The MT concentration in liver of 0. 1% group was significantly higher than that of control group in the 2nd，the 3rd，and the 4th week respectively，and the MT concentration 0f 0.2% group was higher than that of control group in 3rd week. The printing-dying sewage had no significant effect on the MT concentration in kidney(P>0.05).These results showed that printing-dying sewage could affect breeding characteristics and MT level in tissues of C. auratus.
