几种重金属对梭鱼的急性致毒及梭鱼回避反应的试验研究

ACUTE INTOXICATION OF SOME HEAVY METALS TO MUGIL SO-1UY AND THE AVOIDANCE REACTION OF MUGIL SO-IUY

分别于1986和1987年研究了Cu,Zn,Cd对梭鱼的急性致毒效应及梭鱼对Cu,Zn,Cd,Cr的回避反应。结果表明,Cu,2n,Cd对梭鱼均有明显的毒性,其毒性的大小顺序为Ca>Zn>Cd。梭鱼对Cu,Zn,Cd有显著的回避反应,其回避率大小顺序为Cu>Zn>Cd;梭鱼对Cr无明显的回避反应,即使Cr浓度高达100mg/L。

Acute intoxication of some heavy metals to Mugil so-iuy and the avoidance reaction of Mugil so-iuy were studied in 1986, 1987. The results are that: 1) Cu, Zn, and Cd have obvious toxicities to Mugil so-iuy, their order is Cu>Zn>Cd; 2) The avoidance reaction experiment showed that Mugil so-iuy has remarkable avoidance to Cu, Zn and Cd, the avoidance ratio is Cu>Zn>Cd, there is no avoidance reaction to Cr even its concentriion reached 100mg/L.
