Abstract |
The Pacific oyster (Crassostrea gigas) is an introduced species in Chile, that it is farmed the last three decades, mainly in small bays in central north of Chile (18-32°S) and inner seas in Southern Patagonia (38-43°S) . The seed production is done in an industrial hatchery at 32°S, that provides seeds for farmers in Chile, these farmers buy the seed that outgrowth in hanging systems at coastal zones. The aim of the present is to analyze the long term data of C. gigas production in Chile. The results, revealed an increase of production from 50 to 1800 tons between 1996 to 2002, that decreased to 600 tons, between 2002 to 2008 was sustained between 600-400 tons, and decreased before 20 tons the following years. It was denoted a relatively seasonality with low production in winter months (June-August) and high production in summer months (December-February). These variations are due mainly oceanographic conditions such as ENSO phenomenon as well as economical contingences. |
