ON THE SUSPENSION OF "666" FOR THE CONTROI OF ARCULUS AND SOME INSECT LARVAE

摘要: 鲺在我国各大养鱼区是一种常见的大型寄生虫,它常引起大批池鱼患病和死亡。渔农们虽历来以菜油、煤油和茶粕等来治疗,但均无良好的效果。1933年广东陈同白曾以氯化钠、氨水、氯化氨、硫酸铜、蚁醛、过锰酸钾和茶粕等溶液作杀灭鲺的试验,其中只有1:2000的氯化氨能在24小时后杀死鲺,同时对鱼类据说是无害.

Abstract: Experiments on the suspension of "666" in water for the control of Argulus and some larvae of Dytiscidae were carried out both in laboratory and in field. The effective concentration worked out is 1 ppm suspension prepared from the commercial "666" powder which cotains 0.5% of gamma isomer. The suspension of such a concentration causes no ill-effect on fries, fingerling and yearlings of the pond-fishes, nor on the planktonic proto- zoans, rotifers and entomostracal crustaceans. Fingerlings of the pondfishes show no indication of distress in a suspenion of even much higher concen- tration, such as 4 ppm of wettable "666" which contains 6.5% of gamma isomer. The freshwater shrimp appears to be more sensitive to "666" than Argulus and Dytiscidae larvae.
