Predator invasion had devastating, long-term effects on native fish

(Smithsonian Tropical Research Institute) In 1969, 60 to 100 peacock bass imported from Colombia, were introduced into a pond in Panama for sport fishing. Several individuals escaped. By the early 1970s, they colonized the reservoir forming the main channel of the Panama Canal. Forty-five years later, native fish populations in the lake still have not recovered, Smithsonian reports.
