IMO grass carp will continue growing as long as they live. However as the fish age beyond the 4-6 yr mark the growth slows down. they do not grow as much as when they were young and doubling in size. Less growth needs less food to produce that growth. The Pharyngeal teeth development could also play a role in diet selection.
