Ichthyotoxicological examination of carbamate-based pesticides was made according to the norm CSN 46 6807 "Test of Acute Toxicity for Fish". The following compounds were tested: Novozir MN 80, Elocron WP 50, Furadan 5-G and Fundazol. On the basis of the determined LC sub(50) values all compounds have been included among substances highly toxic for fish in the following order: Furadan G-5 > Novozir MN 80 > Elocron WP 50 > Fundazol. The most susceptible fish species was found to be the rainbow trout followed by Poecilia reticulata and carp. The clinical signs and pathoanatomical lesions of the intoxication with carbamatebased pesticides in fish were not specific
