航道疏浚泥悬浮液对黑鲷胚胎的发育及仔鱼摄食生长的影响
The effects of the sludge suspended solution effluent on the development of eggs and larvae of sparus macrocephalus
摘要
Abstract
The sub-acute toxicity experiment was conducted to the sludge suspended solution effect on eggs and larvae of sparus macrocephalus. In this experiment situation, using hydrostatic test method, controlling the temperature at mound 20 ℃, maintaining 60% issolved oxygen saturation of the test water. Mixing engineering dredged mud suspending liquid and filtering sea water together, according-to the logarithmic spacing, the mixture was diluted 4 volume concentration levels(1 : 2、1 : 10、1 : 50、1 : 200). The filter the water was regarded as the contrast group. Each concentration group was set up 3 parallel samples. The results showed that the suspending liquid did not significantly effect on hatching eggs. There was no significant relationship with the concentration of the suspending liquid and the full-length or weight of the growth of the larvae. And then if the concentration of the liquid was enough high level, the affection on the growth of the larvae would be in evidence. During the experiment of larvae feeding, it was not re-markable that the suspending liquid inhibited on the growth of a total length. However, the high level concentration of the suspending liquid had certain suppressant to the body weight growth, but this influence was temporary.关键词
