Feeding behavior of Nile tilapia (Oreochromis niloticus) during grow-out (Video)

This video shows the feeding behavior of Nile tilapia (Oreochromis niloticus) whereas the feeding aggressiveness is obvious and will be always the case if fish are in good health and when the aquatic environment is close to optimum. This Tilapia has a small stomach and so would require a relatively long time to get its feed requirements and that is why dividing the daily ration into two (or more) feedings is usually practiced. In general and as the case of other fish species, the right match between the size of feed pellets and the mouth opening of fish is essential. In other words, if the smallest size of fish population can handle a 4-mm pellet, there is no reason to provide smaller pellets. Similarly, if the pellet size is beyond the ability of fish to ingest it, fish will have no choice but to bite the pellet which results in feed fines which is a form of feed waste.
