Abstract
Comparative studies on effects of CVP and BVP insecticides in sublethal concentrations on young rainbow trout (Salmo gairdneri Rich.) were carried out under laboratory conditions. The insecticide effect was inferred from enzymatic and haematologic analyses. One experiment involved a 14-day exposure to insecticide concentrations corresponding to 5% of 96-h LC50, followed by the brain acetylcholinesterase, blood peroxidase and catalase activity assessment and determination of haematologic indices. The other experiment involved observing changes in the brain acetylcholinesterase activity over 30 days following the 24-h exposure to concentrations corresponding to 50% of 24-h LC50.
