Diversification of Chilean aquaculture: the case of the giant barnacle Austromegabalanus psittacus (Molina, 1782)

Evidence is presented supporting the technical and economic possibilities of giant barnacle Austromegabalanuspsittacus (Molina, 1782) culture, one of the main alternatives for diversifying aquaculture in Chile. Spat collection from the wild varied between different sites in the north and south of th...
