Popis:	The effects of sublethal concentrations of formalin on the erythrocyte counts and plasma glucose of Nile tilapia, Oreochromis niloticus, were investigated using static bioassays and continuous aeration during a 12-week exposure at concentrations of 25.0, 6.25, 3.125, 1.56 and 0.00 (control) mg·l·1• The toxicant led to anemic and hyperglycemic responses in the test fish. The severity of these conditions was directly proportional to the toxicant concentration. However, at 1.56 mg·l-1 concentration no significant effects (P>0.05) were observed in the test fish. Precautions in the successful use of formalin to control ectoparasites on fish is discussed.
