 Recreational fishing tourism in southern Chile's rivers has recently gained worldwide fame attracting actors such as Harrison Ford, Michael Douglas, and Kevin Costner.Fishing began in Chile with the introduction of salmon species into the country at the end of the 19th century — with great success since the salmon did not encounter any large enemies or predators in Chile's cold and temperate waters.Subsequently, the state, first as a social policy and then to promote aquaculture, played an active role in creating fish farms that released into rivers various species like rainbow trout, brown trout, brook trout; and anadromous species such as silver salmon, king salmon, and Atlantic salmon.
