This study present a helpful information about different types of commercially available shrimp feed pellets. The shrimp types taken for the current study are BLANCA 7701, 7702, 7703, 7704, 7703 P, 7704 S. It will be a useful database for the people who work in the intensive shrimp farming. It also helps them in solving problems related to feed handling and storage. The main objective of this work was to study the physical and mechanical properties of six different types of shrimp feed pellets. These properties include: actual diameter, length, surface area, volume, bulk density, moisture content, water absorption, settling velocity, static coefficient of friction and repose angle.
The actual diameter of shrimp feed pellets value ranged from 1.87 to 2.17 mm. The surface area of shrimp feed pellets value ranged from 17.46 to 46.99 mm2. The volume of shrimp feed pellets ranged from 5.6 to 21.4 mm3. The bulk density of pellets of fish feed value ranged from 547 to 768 kg m-3. The moisture content of shrimp feed pellets is around 12 %. The settling velocity of shrimp feed pellets value ranged from 0.02 to 0.1 ms-1. The static coefficient of friction of shrimp feed pellets value ranged from 0.41 to 0.58. The repose angle of shrimp feed pellets value ranged from 22.3° to 30.31°. The percentage of weight gain by shrimp feed pellets due to water absorption was found out to be maximum after 10 minutes of immersion.
