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

Abstract: ABSTRACT.Evidence is presented supporting the technical and economic possibilities of giant barnacle Austromegabalanus psittacus (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 the country and according to type of artificial collector. Growth also varied between sites (greater in the north), technological systems (greater in tubular systems) and depths (greater at 4 m). Average com… Show more

“…Barnacles today are regarded as a delicacy and can fetch relatively high market prices ( Alvarez-Fern andez et al, 2010;L opez et al, 2012). Whale barnacles, on the other hand, were probably not eaten but they are useful archaeological proxies for the consumption of whale meat and/or blubber in the absence of whale bones ( Alvarez-Fern andez et al, 2014;Avery et al, 2008;Jerardino and Marean, 2010;Jerardino and Parkington, 1993;Kandel and Conard, 2013;Moss and Erlandson, 2010;Piana et al, 2007).…”

“…Esta especie es extraída y comercializada extensamente por pescadores locales, debido a que no existe ninguna regulación específica para su extracción. López et al (2012) han señalado que esta especie muestra signos de sobre-explotación. Sus capturas anuales han disminuido considerablemente en los últimos años desde 620 ton en 1990 hasta 168 ton anuales en 2012 (SUBPESCA, 2003;SERNA-PESCA, 2012).…”
