“…At the N-facing locations (with less wave energy) the epiphytic load was significantly greater in shallow waters than in deeper waters. However, our results do not show this pattern in the NW-facing locations, where the potentially greater epiphytic growth under high light conditions may be mitigated by the higher wave action (Liria et al 2009, Galparsoro et al 2010). Nevertheless, it should be noted that factors other than light, such as water movement, temperature, sedimentation and nutrient availability, may vary with depth.…”

Summary:The canopy-forming macroalga Gelidium corneum (Hudson) J.V. Lamouroux plays a major role in the functioning of the subtidal ecosystem of the Cantabrian Sea (northern Spain). Despite its importance, little is known about the factors that may potentially affect the distribution pattern of its epiphytic flora. Here we examine two indirect factors: coastal orientation (N and NW) and depth (3 and 7 m), as proxies for wave exposure and light availability, respectively. We test their effects on the total epiphytic load, alpha diversity (species richness, Shannon, Simpson and evenness measures) and multivariate structure of the epiphytic flora growing on G. corneum in subtidal waters off the Basque coast. Plocamium cartilagineum, Dictyota dichotoma and Acrosorium ciliolatum were found to be the most common epiphytes. Significant interactive effect of coastal orientation and depth were observed for species composition and abundance of epiphytic flora. Increased wave exposure resulted in a lower epiphyte load and a less diverse community, suggesting that under high hydrodynamic conditions epiphytes were more likely to become dislodged from hosts. However, light availability only had a significant effect on the distribution of epiphytes below a certain threshold of wave action, with the epiphytic load being 30-40% greater on shallow bottoms.Keywords: epibionts; host frond; light availability; spatial variability; macroalgae; wave action. Flora epífita deGelidium corneum (Rhodophyta: Gelidiales) en relación a la exposición al oleaje y la profundidad Resumen: El alga formadora de copa Gelidium corneum (Hudson) J.V. Lamouroux tiene un papel fundamental en el funcionamiento de los ecosistemas submareales del mar Cantábrico (norte de España). A pesar de su importancia, se sabe poco sobre los factores que afectan a la distribución de su flora epífita. En este estudio, examinamos dos factores indirectos: la orientación de la costa (N y NO) y la profundidad (3 y 7 m), como factores representativos de la exposición al oleaje y la disponibilidad de luz, respectivamente. Este estudio testa sus efectos sobre la carga total de epífitos, la alfa-diversidad (riqueza de especies, Shannon, Simpson y equitatividad) y la estructura multivariable de la flora epífita que crece sobre G. corneum en las aguas submareales de la costa vasca. Los epífitos más comunes fueron Plocamium cartilagineum, Dictyota dichotoma y Acrosorium ciliolatum. Se observó un efecto interactivo de la orientación de la costa y la profundidad para la composición de especies y la abundancia de la flora epífita. En las localidades con mayor exposición al oleaje la carga epífita era menor y la comunidad menos diversa, sugiriendo que bajo condiciones de un elevado hidrodinamismo los epífitos eran más susceptibles de ser desprendidos de su hospedador. Sin embargo, la disponibilidad de luz solo tuvo un efecto significativo en la distribución de los epífitos por debajo de ciertos umbrales de la acción del oleaje, siendo la carga de epifitos un 30-40% mayor en los fondos ...

“…This implies, on the one hand, that the geology of the area submerged has not been represented (by contrast with Martínez-Torres 1993a) in spite of the fact that interesting new data are being published (e.g. after Galparsoro et al 2010). On the other hand, the superficial Quaternary deposits that exist along several rivers, estuaries and slopes have been overlooked, too, in order to highlight the bedrock geological relationships.…”

“…A further restriction is current legislation, which aims to prevent conflict between users of marine habitats. These conflict-prevention methods hinder the development of near-shore aquaculture as the limited inshore spaces are protected marine habitats (Galparsoro et al 2010;Borja et al 2011;Pascual et al 2011).…”

A sensory and nutritional validation of open ocean mussels (Mytilus galloprovincialis Lmk.) cultured in SE Bay of Biscay (Basque Country) compared to their commercial counterparts from Galician Rías (Spain)

Mussel shell biometry, nutritional quality as well as consumer sensory evaluation of experimental open ocean cultured mussel Mytilus galloprovincialis (Lamarck 1819) were analyzed and compared to that of commercial mussels from Galician Rías available in the local market. Both mussel products were of the same commercial size. In this study, open ocean mussels were significantly higher and wider than those of Galician Rías. In addition, with the exception of ash content, both mussel products showed similar biochemical composition. Regarding fatty acid profiles, however, statistical differences were detected. These differences were not fully reflected in the sensory assessment. In terms of consumer acceptability, both mussel products were considered equally satisfactory.
