摘要
试验研究盐度与碱度对花鲈(Lateolabraxjaponicus)幼鱼的急性毒性结果表明,24h、48h、72h、96h碱度对花鲈幼鱼的半致死浓度(LC50)分别为101.05mmol/L、63.27mmol/L、56.85mmol/L和46.18mmol/L;盐度和碱度联合毒性试验结果显示碱度对花鲈幼鱼24h半致死浓度与盐度显著相关,二者间关系为ALK=125.05-2.18S(n=7,r=0.9756),表明盐度和碱度之间可能存在一定的交互作用。
Acute toxic experiments are carried out to test the tolerance of Lateolabrax japonicus to salinity and alkalinity.The median lethal concentrations(LC_(50) values) of alkalinity (pH=8.44±0.16) to Lateolabrax japonicus fingerlings are 101.05mmol/L,63.27mmol/L,56.85mmol/L and 46.18mmol/L in 24h,48h,72h and 96h;sal-alkalinity mixture tests show that the 24h LC_(50) values of alkalinity to Lateolabrax japonicus vary with salinity.The relationship between them is ALK=125.05-2.18S(n=7,r=0.9756).There is probably an interaction between salinity and alkalinity to some degree.
