What is the fastest growing fish in a pond?

Can you tell me which fish species in a pond exhibits the most rapid growth rate? Is there a specific factor or conditions that contribute to this rapid growth, such as the type of food they consume, the water temperature, or the quality of the water itself? Additionally, is this rapid growth sustainable for the fish and the pond ecosystem as a whole, or could it potentially lead to negative consequences such as overpopulation or depletion of resources?
