几种药物对波部东风螺早期发育的影响

摘要

Several medicines were tested for the early development of Babylonia formosae habei. The results showed: 0.2-0.9 mg/L KMnO4,2-5 μL/L formalin or 1-2 million unit/m3 mycostain can improve the hatching rate of ova or reduce the hatching time. In addition, they can kill the harmful microbia in the water. The safe concentration of formalin, KMnO4, and malachite green to veliger larvae is 1.233 μL/L, 0.138 mg/L and 0.040 mg/L, respectively.%检验了几种药物对东风螺早期发育阶段的影响.测定了东风螺胚胎和幼体对福尔马林、KMnO4及孔雀石绿的安全浓度及不同浓度作用下东风螺受精卵的孵化率.试验结果表明，在育苗过程中，用2～5 μL/L的福尔马林、0.2～0.9 mg/L的KMnO4和100～200万单位/m3的制霉素等药物处理受精卵，可提高受精卵的孵化率或提高孵化速度，并可减少育苗水池中的有害微小生物.在面盘幼虫培育过程中，低于1.233 μL/L的福尔马林或低于0.138 mg/L的KMnO4 可起到控制水体环境的良好效果.波部东风螺幼体对福尔马林的安全浓度为1.233 μL/L，对KMnO4的安全浓度为0.138 mg/L.
