First, let's understand floating fish feed pellets' advantages over sinking feeds. The extruder's screw cooks the material at 120-175°C for about 30 seconds. This enhances digestibility, inactivates enzymes, and increases starch gelatinization. Thus, the feed breaks down slower in water, allowing fish more time to eat.
