乌苏里拟鲿的不可逆点、窒息点及其对5种常见渔药的敏感性研究
Pseudobagrus ussuriensi: the point of no return, suffocation point, and sensitivity to five aquacultural drugs
摘要
Abstract
Pseudobagrus ussuriensis was studied for its initial feeding rate, point of no return (PNR), suffocation point, and acute toxicity of five aquacultural drugs to through an ecological method.At 22 ～ 23 ℃, the maximum value of the initial feeding rate was 100％ in the seventh day after hatching.The PNR of larvae appeared on the 13th day after hatching.The suffocation point of Pseudobagrus ussuriensis was positively correlated with water temperature (R＝0.909 3, P＜0.001) and negatively correlated with body weight (R＝-0.881 6, P＜0.05).At 24 ～ 25 ℃condition, the safe concentrations of CuSO4+FeSO4(Ratio 5∶2), KMnO4, CuSO4, HCHO, and NaCl to Pseudobagrus ussuriensis were 0.34, 0.24, 0.27, 4.03, and 1135.56 mg/L, respectively.The sensitivity Pseudobagrus ussuriensis toward the five commonly-used aquacultural drugs was KMnO4＞ CuSO4＞ CuSO4+FeSO4(Ratio 5∶ 2)＞HCHO＞ NaCl.关键词
