This work presents a useful information about different fish feed pellets, which will be database for the people work in the intensive fish farming which help then in solving many problems concerning the feeding effectiveness and feed handling and storage. The main objective of this work was to study the physical and mechanical properties of fish feed pellets contained different protein ratios and pellets sizes. These properties include: actual diameter, expansion rate, surface area, volume, weight, bulk density, durability, floatability, moisture content, water stability, repose angle and crushing load. The actual diameter of pellets fish feed value ranged from 1.51 to 4.55 mm. The expansion rate of pellets fish feed value ranged from 33.31 to 40.94%. The surface area of pellets fish feed value ranged from 10.57 to 71.13 mm2. The volume of pellets fish feed 4.04 to 79.09 mm3. The weight of 100 pellets value ranged from 0.11 to 5.51 g. The bulk density of pellets of fish feed value ranged from 267.11 to 711.35 kg m-3. The durability of pellets of fish feed value ranged from 70.66 to 92.62%. The floatability of pellets of fish feed value ranged from 79.51 to 96.45%. The moisture content of pellets of fish feed value ranged from 16.68 to 17.82%. The water stability of pellets of fish feed value ranged from 54.15 to 91.78%. The repose angle of pellets fish feed value ranged from 27.00 to 38.00°. The crushing load of pellets fish feed value ranged from 6.13 to 33.28 N.
