Sk. Srivastava et al., LETHAL TOXICITY OF DELTAMETHRIN (DECIS) TO A FRESH-WATER FISH, HETEROPNEUSTES-FOSSILIS, Journal of advanced zoology, 18(1), 1997, pp. 23-26
A four-day static renewal acute toxicity test was performed to determi
ne the LC50. value of deltamethrin for the freshwater catfish, Heterop
neustes fossillis. The LC50 values, their upper and lower confidence l
imits and slope functions were calculated. The LC50 values for 24, 48,
72 and 96hr are 3.10,2.30, 2.10 and 1.86 mu g/l, respectively.
