The introduction of a new fish species into an aquatic ecosystem can bring about many challenges for fisheries managers. Questions might arise for the manager regarding the initial sportfish survival rate, grow rate, reproduction and recruitment, and what kind of impact will the introduction have on the already established populations found in the water body. A new population of fish is often protected using length limit regulations, allowing biologists to gain insight on whether the population will be self-sustaining or in need of periodic stockings. Age and growth information is used to understand population dynamics, estimate annual mortality and …
