Abstract
Tests of acute toxicity for rainbow trout fry of chlorfenviphos and bromfenviphos were undertaken in order to establish the LC50 values. Studies were also made on the effect of lethal concentrations, corresponding to 24 h LC50 upon the activity of selected enzymes and hematological indices. Activity of brain acethylcholinesterase, and blood peroxidase and catalase, was assessed. Hematological studies embraced: content of hemoglobin, hematocrit, number of red and white corpuscles, percentage share of lymphocytes, red/white cell ratio, and MCV, MCH, and MCHC indices.;
