Abstract
The food and feeding habit of seven fish species from Ayeyawady River were exmined during December 2017 to May, 2018. Observation of five species, the relative length of alimentary range in Mystus bleekeri, from 0.87 to 0.95; in Mystus leucophasis, from 0.94 to 1.23; in Clarias batrachus, from 0.91 to 0.98; in Macrognathus aral, from 0.55 to 0.95 and in Macrognathus armatus, from 0.67 to 0.88 respectively. Their ration ranges is shorter than of each standard length and carnivorous in feeding habitat. In Puntius sarana, the relative length of alimentary canal ranged from 1.55 to 2.11. The ratio is 1.5 to 3 times of the standard length and omnivorous. In Labeo rohita, the relative length of alimentary canal ranged from 8.44 to 12.6. This ratio is longer the standard length and herbivorous. The information on the feeding habits of fish helps to know about the inter-specific relationship of aquatic fauna and productivity of the water body.
