During the artificial breeding of river crabs in 1999 and 2000, Lagenidium was found in river crabs (Eriocheir Sinensis)and their larvae. This article deals with the preliminary curing effect of the disease by Ca(ClO) 2, malachite green and treflan. Results showed that Lagenidium could be prevented if the river crabs were dealt with by 2 mg/L of malachite green and the incubation ponds were dealt with by 250 mg/L of Ca(ClO) 2. The zoeae survival and metamorphosis rates of the crabs reached the best level when the concentration of treflan was 0.01 mg/L.
