【摘要】 报道了眼斑拟石首鱼苗种对盐度、有效氯、高锰酸钾、硫酸铜耐受力的实验，测定了它的呼吸耗氧量和窒息点：缺氧浮头时的溶氧值为1．86mg／L，窒息点范围为0．79～0．38mg／L。实验表明：有效氯毒性极强，高锰酸钾次之，CuSO4·5H2O较弱。采用1×10(－6)以下的CuSO4·5H2O处理眼斑拟石首鱼鱼苗是安全的。更多还原

【Abstract】 The effects of salinity,active chlorine, kalium permanganicum, copper sulfate on the red drum fry were reported in this paper. A preliminary observation on respiration rate and suffocation point was also carried out. When the concentration of the dissolved oxygen was 1. 86mg/L, the fry floated at the surface due to lack of oxygen. The suff0cation point ranged between 0．79～O.38mg /L.更多还原
