2000年4月研究了斜带石斑Epinephelus coioides寄生拟合片盘虫Pseudorhabdosynochus epinepheli的防治方法.海水福尔马林对拟合盘虫的作用表现为:25 min处理的半致死浓度为250×10-6,50 min处理的半致死浓度为50×10-6.淡水福尔马林的效果为:3 min的半致死浓度为83×10-6,纯淡水处理的半致死时间为21 min.海水福尔马林对斜带石斑的毒性表现为:30 min和45 min的半致死浓度分别为940×10-6和645×10-6.淡水福尔马林对斜带石斑的毒性表现为:5 min和10 min的半致死浓度分别为1 300×10-6和500 ×10-6.福尔马林处理海水中的斜带石斑半致死浓度介于600×10-6～1 000×10-6,淡水处理对斜带石斑半致死浓度介于95×10-6～115×10-6.淡水中斜带石斑的半麻醉和半致死时间分别为95 min和115 min.以上结果表明:海水和淡水福尔马林对石斑拟合片盘虫的致死浓度,处于斜带石斑的安全范围之内.

Prophylactic methods against Pseudorhabdosynochus epinepheli (Monogenea) infection on the fish Epinephelus coioides were investigated in April 2000.The effect of formalin in seawater on P.epinepheli was that the semi-lethal concentration is 250×10-6 for 25 min,and 50×10-6 for 50 min.The effect of formalin in freshwater on P.epinepheli is reported as:the semi-lethal concentration was 83×10-6 for 3 min.The semi-lethal time for freshwater alone was 21 min.The toxicity of formalin in seawater to E.coioides was assessed:the semi-anaesthetic concentration was 940×10-6 in 30 min and 645×10-6 in 45 min.The toxicity of formalin in freshwater to E.coioides was as follows:the semi-anaesthetic concentration was 1 300×10-6 in 5 min and 500×10-6 in 10 min.The semi-lethal formalin concentration to E.coioides in seawater was between 600×10-6 and 1 000×10-6,and in freshwater was between 250×10-6 and 500×10-6.The semi-anaesthetic and semi-lethal time of E.coioides in freshwater were 95 min and 115 min respectively.These results demonstrated that the lethal formalin concentrations for P.epinepheli in both seawater and freshwater fell in a safe range for E.coioides.
