The size of feed pellet and the width of fish mouth – Video

 

The inserted video shows the feeding of tilapia fingerlings. As shown in the video, the size of the floating pellets is too large to be swallowed by the fingerlings that are chasing the feed trying to get a bite after another. In this case, fish will spend unnecessary extra energy during feeding that would otherwise be used for growth. Moreover, higher rates of feed loss are expected through the leaching of pellet remains in the water column. In general, the pellet size is considered optimal at 25% – 50% of the width of fish’s mouth.
