A preliminary study of hydrogen sulphide toxicity on juveniles of Macrobrachium rosenbergii (de Man)
Static bio-assays were performed for 96-hour period to determine the mean lethal concentrations (LC50) of hydrogen sulphide toxicity on juveniles of Macrobrachium rosenbergii. Two broods were tested and LC50 values were determined for 24, 48, 72 and 96 hours The LC50 values were 6.36, 4.25, 3.09 and 2.57 mg/l H2S for brood l and 5.57, 4.79, 4.25 and 4.20 for brood 2 respectively, for 24, 48, 72 and 96 hours. The safe concentration of hydrogen sulphide determined for juveniles of M. rosenbergii w as 0.26 mg/l.
