The inducibility of the freshwater crayfish (Astacus astacus) biotransformation enzymes with model inducers (Aroclor 1254, beta-Naphthoflavone, Phenobarbital) were investigated three days after intra cephalothoracic injection in the fasting crayfish at 5 degrees C. Of the monooxygenase activities, 7-ethoxycoumar in O-deethylase increased in the hepatopancreas significantly (p less than 0.05) after beta-naphthoflavone administration. Benzo(a)pyrene hydroxylase did not change. Aroclor 1254 and phenobarbital injection elevated hepatopancreatic glutathione S-transferase activity (p less than 0.05).
