Abstract

The structure and morphometries of the alimentary canal of Channa orientalis,
C. punctatus, C. striatus and C. marulius are described in relation to their food
and feeding habits. The general pattern of the alimentary canal was found to
be similar and of carnivorous type in the four species studied. C. striatus was
found to be the most carnivorous as indicated by the structure and morphometries
of the alimentary canal and nature of gut content followed by C. marulius and
C. orientalis was found to be the least carnivorous. Pattern of the mucosal folds
in the different regions of the alimentary canal showed inter and intra-specific
variations.
