摘要
淡水稀释取自盐场的卤水,调节Ca2+、Mg2+的质量浓度和比例,设置系列梯度,进行凡纳滨对虾的养殖试验,测定生长比速及超氧化物歧化酶(SOD)和碱性磷酸酶(AKP)的酶活性。试验表明,过高或过低的Ca2+质量浓度都会影响凡纳滨对虾的存活和生长,在Ca2+质量浓度为320 mg/L,Ca2+/Mg2+为1∶2.5时,其存活与生长最佳;同时SOD和AKP酶活性也最高。酶活性可以指示凡纳滨对虾的生长状况。
The effects of Ca^2+/Mg^2+ in brine water from salt works on survival, growth and activities of enzymes (AKP and SOD)of white legged shrimp (Litopenaeus vannamei) were conducted using Ca^2+/Mg^2+ of aseries of concentration and ratios. The results showed that the highest growth rate and activities of enzymes in the shrimps occurred at Ca^2+ concentration of 320 mg/L with, Ca^2+/Mg^2+ ratio of 1:2.5, indicating that the activities of AKP and SOD can indicate the healthy status of the shrimp.
