Chitinolytic activity was searched for in oesophagus, stomach, intestine, pyloric caeca and liver of two sympatric closely related species of Serranidae (Teleostei, Perciformes): Serranus cabrilla (L.) and Serranus scriba (L.) living near the rocky shore of Calvi (Corsica, Mediterranean Sea). The chitinase activity was much higher in stomach than in other parts of the digestive tract and liver in both species. In extracts of gastric mucosa, the chitinase activity was more important in S. cabrilla than in S. scriba; an appointed situation was found in the extracts of intestine and pyloric caeca. These findings are discussed as aspects of the ability of these species to share very near ecological niches.
