| 摘 要： | 在室内模拟小水体中,开展了不同密度尼罗罗非鱼和鲢鱼抑制蓝藻生长的对比试验.结果表明:尼罗罗非鱼和鲢鱼对水体中蓝藻绿藻过量增长均有不同程度的抑制作用,其中尼罗罗非鱼抑制消除蓝藻的效果优于鲢鱼,且尼罗罗非鱼的密度越高抑制消除蓝藻的速度越快;尼罗罗非鱼对水体中营养盐水平消除无明显贡献,但能有效提高水体的透明度,降低水体的pH值.

| Abstract: | Comparative experiments on the control of cyanobacteria by sliver carp and by Nile Tilapia with different stocking densities was conducted in artificial waters.Both Nile Tilapia and sliver carp could control the growth of cyanobacteria,and the effect was better by Nile Tilapia than by sliver carp.The higher the density of Nile Tilapia,the faster the remove rate of cyanobacteria.Nile tilapia did not affect nitrogen and phosphorus nitrient in the waters,however,it could effectively improve the transparency of... |
