Abstract
Bioassay experiments with redclaw crayfish hatchlings revealed 96-h LC50 values for total ammonia, un-ionized ammonia and nitrite were 29.3 mg L-1, 4.4 mg L-1 and 1.03 mg L-1, respectively. After a 24-h exposure to 0.4 mg L-1 nitrite, growth during the following month was decreased by 17% and survival by 5%. A 48-h exposure to 0.4 mg L-1 nitrite decreased subsequent growth by 45% and survival by 12%. Exposure to 0.6 mg L-1 for 24 h decreased growth by 67% and survival by 48%. Exposure to 0.6 mg L-1 for 48 h resulted in 100% mortality before the end of a one month culture period.
