“…The study area extended from 44°23′N to 43°56′N and from 6°31′W to 5°47′W (Fig. ) over the Avilés submarine canyon, which is part of a complex network of canyons and valleys off the central Cantabrian margin in the Bay of Biscay (Northern Iberian Peninsula; Gómez‐Ballesteros et al ). Samples were collected on board the research vessel B/O Sarmiento de Gamboa during three oceanographic cruises: between 03 and 13 March 2012 ( BIOCANT 1 ); between 27 September and 06 October 2012 ( BIOCANT 2 ), and between 24 April and 04 May 2013 ( BIOCANT 3 ).…”

We determined the stable nitrogen isotope composition (δ15N values) and body size of taxonomic groups in a zooplankton community in the Cantabrian Sea (southern Bay of Biscay) to explore seasonal and depth (0–2000 m) variations in the size‐based trophic structure and their coupling to the production cycle. The positive linear relationship between δ15N values and log‐transformed body size reflects the dominance of new vs. regenerated production. The slope of the relationship (b) is high during productive periods and low when herbivory declines and the food web is more dependent on recycled production. This variation can be attributed to high δ15N values of the smallest plankton after repetitive cycles of microbial degradation. Downward transport of organic matter after the spring phytoplankton bloom was captured by a steady variation from low values of b at the surface to high values at the bathypelagic zone, where the imprint of the spring production pulse could be detected. Variation in b reveals that the mesopelagic and bathypelagic zooplankton communities are as dynamic as their epipelagic counterparts. This shows the efficiency of δ15N vs. body size relationships to capture fast, transient ecosystem processes without need for lengthy incubations or complex rate measurements.

“…In the area of influence almost all types of fishing gear are used (trawl, longline, purse seine, and gill nets). This makes this area an excellent example of how a structurally and geographically complex zone (Gómez-Ballesteros et al 2014) is exploited by mixed fisheries.…”

“…The Avilés Canyon System (Fig. 1) is a complex region of canyons and valleys comprising 3 main canyons of different morphostructural characteristics (Gómez-Ballesteros et al 2014). The near continental shelf is generally narrow; the width varies from 12 km (where the head of the Avilés Canyon is incised) to 40 km.…”

Spatial characterization of the fisheries in the Avilés Canyon System (Cantabrian Sea, Spain)

Marine protected areas are one of the main tools in ecosystem-based fishery management. This approach requires analyzing the role of fisheries in the ecosystem by, for example, identifying fishing tactics and analyzing the spatial distribution with sufficient precision to allow us to determine whether fishing activities and the habitat or ecosystem to be protected can coexist spatially. In the Avilés Canyon System (Cantabrian Sea, Spain), we detected 6 different gears and 17 fishing tactics were identified by a non-hierarchical classification technique (CLARA). The spatial distribution of demersal fishing activity is strongly affected by the topography of the study area and the large presence of rocky ground. There is a clear spatial segregation between gear types, mainly due to the operating requirements of the gears and the distribution of target species. This minimizes conflicts between different components of the fleet. The fishing tactics targeting pelagic species were mainly located on the coast and shelf, while those targeting demersal species were used on the shelf and slope. Longline fishing tactics are those that had a more restricted spatial distribution.
