Fish samples were dissected and the stomach contents emptied into Petridishes containing 10% saline solution and observed under a dissecting microscope.

The result shows that the fish feed mainly on mud (4.31%), sand particles (6.00%), plant materials (80.65%), fish remains (5.81%), insect parts (2.58%) and small gravel (0.65%) respectively.
