Type of food present was identified and noted and the Index of Preponderance was calculated. The crabs were captured using a traditional fishing line and traps. Results shown that the stomach of P. pardus contains detritus (64,87%), phytoplankton (28,60%), crustacean remains (5,88%), and algae (0,49%).
