The toxicity of ammonia to Eriocheir sinensis juveniles was determined. The 24 h-, 48 h-, 72 h-, 96 h-LC(50) values of total ammonia (TAN) were 251.68, 217.61, 156.05, and 119.67 mg L(-1), respectively. Following these results, crabs were then exposed for a 2-day period to 20, 40, 60 and 80 mg L(-1) TAN and sampled at 3, 6, 24 and 48 h for changes in(More)
The lethal concentration of nitrite to the Chinese mitten crab Eriocheir sinensis was tested by exposing the animals to 17.78, 23.71, 31.62, 42.17, and 56.23 mg NaNO2 L(-1) at 20 degrees C for 24, 48, 72, and 96 h. The corresponding LC50 value for each time exposure was 43.87 (38.70-51.70), 40.24 (34.88-46.01), 38.87 (33.72-46.01) and 38.87 (33.72-46.01) mg(More)
