“…En el caso de Chile, las principales algas de importancia económica han sido de la división Rhodophyta, de las cuales las más cosechadas han sido Sarcothalia crispata, Mazzaella laminarioides, Gigartina skottsbergii, Gelidium lingulatum, Chondracanthus chamissoi y Gracilaria chilensis (Buschmann et al 2001). Para estas dos últimas macroalgas, el desarrollo del cultivo mediante propagación vegetativa ha potenciado eficientemente su producción de biomasa.…”

“…Mientras que la agarofita G. chilensis es el caso más emblemático en Chile, donde el cultivo artificial mediante propagación vegetativa ha sido desarrollado con técnicas de siembra, cosecha y metodologías de poda (e.g., Westermeier et al 1991). Otra agarofita cosechada en menor medida en Chile es Ahnfeltia plicata (Buschmann et al 2001;Mansilla et al 2012), la cual en la actualidad no presenta una pesquería efectiva en la región de canales y fiordos Magallánicos.…”

“…However, they are cultured with technologies developed for similar species in other countries (Navarro & Gutiérrez, 1990). Only around 14% correspond to two species of native algae, cultured with national technologies (Santelices, 1996;Buschmann et al, 2001Buschmann et al, , 2008. Aquaculture diversification is a strategic challenge that must be oriented towards the culture of native species, given that dozens of these commercially interesting species are exploited exclusively by fisheries (López et al, 2008a).…”

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 commercial size in the national market was reached over a period between 18 and 24 months. A long-line can produce between 7 to 10 gross ton during this period, therefore average annual fisheries production can be reached with only 10 to 30 longlines, in an area of 1 to 3 ha. There is demand for this resource in the external market, particularly in the Japanese market, either as product similar to "fujit subo" (Balanus rostratus), or as a new resource; the relationship between production costs and price determines that giant barnacle culture has commercial potential. Economic indicators for cultured giant barnacle were as follows: net present value (NPV): US$ 490,000; internal rate of return (IRR): 32%; discounted payback period (DPBP): 4 years. Results obtained suggest the natural bank repopulation option, and the development of mass cultures. Giant barnacle culture is based on biological characteristics that differentiate it from other crustaceans species, as well as simple and economic production technologies and favourable economic projections on external markets. Keywords: Austromegabalanus psittacus, barnacle culture, spat collection, commercial size, aquaculture diversification, Chile. Diversificación de la acuicultura chilena: el caso del cirripedio giganteAustromegabalanus psittacus (Molina, 1782) RESUMEN. Se presentan evidencias de las posibilidades técnicas y económicas del cultivo del cirripedio gigante o "picoroco", Austromegabalanus psittacus (Molina, 1782). Esta especie es una de las principales alternativas para la diversificación de la acuicultura en Chile. La captación de semilla desde el ambiente varió entre distintos sitios del norte y sur del país y según el tipo de colector artificial. El crecimiento también varió entre localidades (mayor en el norte del país), el tipo de sistema (mayor en sistemas tubulares) y profundidad (mayor a 4 m). La talla comercial promedio del mercado nacional se alcanzó entre 18 y 24 meses. Un longline puede producir entre 7 y 10 ton brutas en ese periodo, por lo que la producción promedio anual por pesquería se puede alcanzar con sólo 10 a 30 long-lines, en un área de 1 a 3 ha. Existe demanda de este recurso en el mercado externo particularmente en el mercado japonés sea como símil del "fujit subo" (Balanus rostratus) o como recurso nuevo; las relaciones de costos de producción y precios indican que tienen potencialidades en cultivos comerciales. Los indicadores económicos para el picoroco congelado proveniente de cultivo fueron los siguientes: el valor actuali...

“…Gracilaria has been extensively exploited along the Chilean coast with an average extraction of 75,000 t per year (Anuario Estadístico de Pesca, 2001). The development of Gracilaria management strategies and establishment of over 500 farming centers sustain the high production of this seaweed with important revenues for Chile (Buschmann et al 2001). Along the Chilean coast, Gracilaria was represented by several species.…”

The present work is a population morphometric study of Gracilaria from different environments along a latitudinal gradient of the Chilean coast that cover 1,500 km. Gracilaria species have been extensively exploited with an average extraction of 75,000 t per year. In Chile this seaweed is usually found in sandy bottom bays between Antofagasta (23º29'S -70º25'W) and Chiloé (42º03'0''S -73º11'0''W). Observations were made in 51 plants. Macroscopic observations were done in fresh plants, microscopic characters were determined in transversal sections with 20% Karo syrup and stained with aniline blue. Numerical analyses were performed by one-way ANOVA and Principal Component Analysis. The latter analysis was performed for those characters with significant differences among the localities: basal constriction of branches, branch frequency, cortex cell diameter, subcortex cell diameter, thickness of the cortex and medullar cell diameter. The results of the Principal Component Analysis showed that 61% of the variance corresponded to the two first components. There were not observed groups clearly defined. The data suggest that along the coast of Chile there is only one morphotype that corresponds to the description of Gacilaria chilensis Bird, McLachlan et Oliveira, 1986 and it fits to the bulk of the material utilized in commercial production.
