 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.As a result, a number of species have adapted well to the new environment.
