In the present research, investigation was carried out for variation in settling velocity of some pelletized fish pellets in relation to floating time (T f ), diameter of pellets and temperature along with their water absorption properties under defined laboratory conditions. Among two diets of different ingredients DI and DII, it was observed that time for float (T f ) were greater at high range of temperature than lower range of temperature, for all tested pellets dimension (3 mm, 6 mm, 9 mm)

On the other hand percent weight increments for diet DI were noted maximum for pellets size of 3,6 and 9 mm after 10 min of immersion i.e., 33.33, 55.55 and 38.46%, respectively, when compared to dry pellets.
