But Hilborn said fishing laws in the US and elsewhere already tightly control competition because of overfishing that wiped out fish such as the cod in the Grand Banks off the coast of Newfoundland.

The recent invasion of Indo-Pacific lionfishes (Pterois volitans and P. miles) in the Caribbean may have been facilitated by overfishing large predators capable controlling their rapid spread and population explosion [78] and is alarming considering the strong predatory effects lionfish can have on native fishes [79].

In the Caribbean, a combination of release from top-down control due to loss of the sea urchin Diadema antillarum to disease, coupled with overfishing, eutrophication, and destruction of the physical structure of the reef due to hurricanes, led to nearly complete loss of Caribbean corals [3], [11] [13].
