What is a consequence of overstocking fish in aquaculture systems?

Overstocking fish in aquaculture systems leads to increased competition for resources among the fish. When too many fish are present in a confined space, they must compete for limited resources such as oxygen, food, and space. This competition can result in stress, reduced growth rates, and the potential for increased aggression among individuals, which can lead to injuries or fatalities. The overcrowding can also compromise water quality, as the waste produced by the fish accumulates more quickly than it can be processed or removed effectively. Therefore, the consequence of overstocking directly impacts the health and well-being of the fish, as well as the overall sustainability of the aquaculture system.
