| 摘 要： | 以水体不同浓度铬（CrCl3.6H2O)处理草鲤鱼卵和鱼苗，观察铬对鱼卵的发育和鱼苗的毒性作用，结果表明：铬处理组浓度高于（2mg/L)对鱼苗，鱼胚发育有毒性作用；染毒7天内，10mgCr/L组鱼苗致死率30％，草，鲤鱼卵孵化率分别下降46％和88．9％，15mgCr/L组草鱼苗致死率达100％，鱼卵孵化率为零，两种鱼对铬的耐受量无明显差异。

| Abstract: | The eggs and fries from grass carps and common carps were treated with different concentrations chromium in water body.It was found that toxic effects was caused at the concentration of more than 2mg/L groups treated with Cr.The fries lethal rate of 10 mg Cr/L groups reached to 30% during 168h.The eggs hatching rate of grass carps and common carps descended 46% and 88.9% respectively.The fries lethal rate of grass carps in 15 mg Cr/L group was 100% and the eggs hatching rate was zero.The endurance to chromium of two kinds of fish has no significantly. |
