SciencePhoto: HT WorldUS Introduced Trout to Lake Titicaca in 1930s, Threatening Native Fish
In the 1930s, the US sent about 500,000 trout eggs to Lake Titicaca, located on the Peru-Bolivia border, to boost fishing. The trout thrived and became one of the most invasive species in southern Peru. This introduction has harmed native fish populations, with two species possibly now extinct. The plan originated after Peruvian and Bolivian authorities sought US help to improve local livelihoods.
