For a correct understanding of the feeding habits of a fish, a study of the anatomy of the organs of feeding and digestion is necessary. ‘An examination of the special relations of food and feeding structures gives clues, not only to the present significance of fishes but also their past effect on life at large, showing how they must have modified the course of evolution’ (Forbes, 1888). While observing the morphological characters of alimentary canal of Channa punctatus it is found that the alimentary canal is demarked into oesophagus, stomach, pyloric caecae, intestine and rectum.The mean alimentary canal length (ACL) observed was 17.4 ± 1.57cm. The Pearson correlation coefficient of alimentary canal length (ACL) and total length (TL) of Channa punctatus (r) = 0.999.

Channa punctatus, oesophagus, stomach, pyloric caecae.
