“…These species have been shown to have a high growth rate in integrated multitrophic aquaculture systems. At a stocking density of 6 g FW L -1 , a biomass production of 22-29 g DW m -2 d -1 was found (Viera et al 2011). A growth rate of 10-16% d -1 was reported for G. longissima and H. incurva .…”

“…In extensive aquaculture ponds, the growth rate of G. longissima was 9% d -1 (Hernández et al 2006). Halopithys incurva has been cultivated in fishpond effluents at 8 g FW L -1 with a production of about 5 g DW m and nitrogen uptake efficiency of 90-99%; however, at 6 g FW L -1 , the average biomass productivity was 16-19 g DW m -2 d -1 (Viera et al 2011). Polyphenols were detected in all the analyzed species, but were higher in the red algae Gelidium pusillum and encontrados por Sarikurkcu et al (2009) en extractos de plantas terrestres, en los que se observó una fuerte correlación entre la polaridad de los extractos y su potencial antioxidante.…”

INTRODUCCIÓNLos organismos marinos, incluyendo las algas y los líquenes, han atraído la atención de muchos investigadores como fuente de compuestos bioactivos debido a sus propiedades, la diversidad de sus moléculas y sus nuevas estructuras químicas que son complejas y difíciles de sintetizar químicamente. Las algas proporcionan una excelente fuente de compuestos bioactivos como carotenoides, polisacáridos, proteínas, lípidos, ácidos grasos, pigmentos, vitaminas, polifenoles y microelementos, entre otras sustancias (Borowitzka Analysis of antioxidant capacity and bioactive compounds in marine macroalgal and lichenic extracts using different solvents and evaluation methods ABSTRACT. Natural extracts of macroalgae are widely recognized for their antioxidant properties. In this work, the antioxidant capacity of various aqueous and hydroalcoholic extracts obtained from red and green marine algae and from one marine lichen collected from different sites in southern Spain (intertidal and estuarine waters) was evaluated by different methods: ABTS free radical scavenging assay, DPPH assay, and β-carotene bleaching method (BBM). Contents of total lipids, total carbohydrates, and UV photoprotectors with antioxidant capacity, such as mycosporine-like amino acids and phenolic compounds, were determined. Among the extraction solvents, the highest extraction yield was observed in H 2 O and 20% MeOH (v/v). The highest antioxidant activity was found in the extracts of the red macroalgae Hydropuntia cornea, Gracilariopsis longissima, Halopithys incurva, and Porphyra umbilicalis, whereas the lowest activity was detected in the green macroalga Ulva rotundata. In general, the antioxidant activity was higher using DPPH than BBM and ABTS. Even so, the ABTS assay is an easy and quick test that provides a comprehensive view of the entire extract in both the lipophilic medium and hydrophilic medium. The antioxidant activity was related to the composition of bioactive compounds and synergistic action is not discarded. The biotechnological use of macroalgal extracts with high antioxidant capacity is discussed.Key words: antioxidants, bioactive compounds, extracts, lichen, macroalgae. RESUMEN.Los extractos naturales de las macroalgas son ampliamente reconocidos por sus propiedades antioxidantes. En este trabajo la capacidad antioxidante de diversos extractos acuosos e hidroalcohólicos obtenidos de algas marinas (rojas y verdes) y de un liquen marino, recolectados en diferentes puntos del sur de España (aguas intermareales y estuarinas), fue evaluada mediante diferentes métodos: método ABTS, ensayo DPPH y método de decoloración del β-caroteno (BBM). Se determinó el contenido de lípidos totales, carbohidratos totales y fotoprotectores de radiación UV con capacidad antioxidante como los aminoácidos de tipo micosporina y compuestos fenólicos. Entre los solventes de extracción, el mayor rendimiento de extracción se observó en los solventes H 2 O y MeOH 20% (v/v). La mayor actividad antioxidante se encontró en los extractos de las macroalgas roj...

“…Seaweeds can provide complete or partial protein nutrition for abalone (Bautista-Teruel, Millamena, & Fermin, 2001;Bilbao et al, 2012;Kemp, Britz, & Aguero, 2015;Mulvaney, Winberg, & Adams, 2013;Viera et al, 2011), sea urchins (Cook & Kelly, 2007) and shrimp (Cruz-Suarez, Tapia-Salazar, Nieto-Lopez, Guajardo-Barbosa, & Ricque-Marie, 2009;da Silva & Barbosa, 2009;Felix & Brindo, 2013). In contrast, the inclusion of seaweed in diets of commercial fish (herbivores or carnivores) at levels greater than 10% results in reduced growth and feed utilisation (Table 2), although there are some promising results for tilapia (Stadtlander et al, 2013).…”
