Suppose That a Lake Commonly Used for Fishing, Both for a Food

Suppose that a lake commonly used for fishing, both for a food resource and for pleasure, becomes depleted due to overfishing. The community decides it will bring in another fish in large numbers to help reestablished the fish population. The new fish, the Nile perch, is a large, voracious eater, and adapts well to new locations. Which of the following is the best conclusion for this scenario?

A) Bringing in a nonnative species is smart because it most likely has no predators and can flourish.
B) There will be plenty of fish for recreational fishing and for food.
C) Bringing in a nonnative species is risky as the local fish might become prey for the nonnative fish.
D) The population of native fish recovers and flourishes.
E) Due to overfishing, the lake will not be able to provide food or recreation.
