五种理化因子对眼斑拟石首鱼苗种的影响
Effects of Some Environmental Factors on Fry of Sciaenops ocellatus
【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。
【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.
