高锰酸钾、福尔马林防治大银鱼卵水霉病试验

Study on Preventing Saprolegniasis of Salangidae Eggs by KMnO_4 and Formalin

以不同浓度和不同浸洗频率的高锰酸钾和福尔马林溶液防治大银鱼卵水霉病试验表明， 浓度为１５－０ｍｇ／Ｌ的高锰酸钾和２００－０ｍｇ／Ｌ的福尔马林溶液对水霉病有很强的抑制作用， 而对其出苗率无明显影响。

In this experiments ,eggs of Salangidae were bathed in the solution of KMnO 4 and Formalin to prevent occurrence of Saprolegniasis in different concentrations and in frequencies. The results indicate that 15.0mg/L KMnO 4 and 200.0 mg/L Formalin have strong effects on restraint of Saprolegniasis, and have not distinct effects on rate of emergence.
