In order to investigate the biosynthesis of taurine in common carp, organic distributions of cysteinesulfinate decarboxylase (CSD) and cysteamine dioxygenase (CAO) activities were determined. The highest CSD activity was observed in kidney, followed by brain, hepatopancreas and gill. On the contrary, the highest CAO activity was observed in hepatopancreas, which value was twice as high as hepatopancreatic CSD activity. A weak activity was detected in intestine, spleen, heart and brain.
