Abstract
1. 1. The xenobiotic biotransformation ability of vendace ( Coregonus albula) was studied. 2. 2. Cytochrome P-450, monooxygenase and UDPglucuronosyltransferase activities were detected in vendace liver, gills, kidneys, intestine and heart. 3. 3. The monooxygenase activity seems to be very sensitive to temperature and it is already inactivated at temperatures above 20°C. 4. 4. Monooxygenase activities in vendace tissues were lower than in the liver of cultivated rainbow trout ( Salmo gairdnerii) or rat ( Rattus norvegicus). UDPglucuronosyltransferase activities in vendace liver were as high as in the liver of rainbow trout and higher than in rat (measured at 18°C). The UDPglucuronosyltransferase activity in vendace gills was much higher than in the liver of all the species studied.
