چکیده مقاله:
The Chilean fisheries have a marked increase in the last three decades, because economical directions that generate an increase of economic activities for increase the economical activities, that many decades ago were characterized by the dependence exclusive of cooper mining. The aim of the present review is do a long-term analysis of fisheries activities in Chile. As overview the fisheries has an increase the last three decades, with marked fluctuations in two periods, approximately, in 1991 and 1998 where have low captures due ENSO phenomenon, that is a surface temperature increase in the north of Chile that generate low species diversity and fisheries resources abundances. Also, in 1998, with ENSO phenomenon it happened a marked over-extraction of pelagic industrial fisheries that collapsed the fisheries industry in the north of Chile (18-23°S). The fisheries resources are mainly pelagic and demersal fishes, and invertebrates such as molluscs and sea urchins, and the fisheries are mainly from marine origin. The aquaculture in Chile has a marked increase the last three decades too, and the main activity is salmon farming in inner seas at south of Chile (41-53°S). The products of Chilean fisheries and aquaculture are mainly for exportation, and the fisheries consumption per capita in Chile are relatively low in comparison to the other countries of the world.
