Spatio-temporal variability of discards in the fishery of the deep-sea red shrimp <em>Aristeus antennatus</em> in the northwestern Mediterranean Sea: implications for management

Abstract: Summary:In this work we analysed the spatio-temporal variability of discards in the fishery of the deep-sea red shrimp Aristeus antennatus in the northwestern Mediterranean Sea. We sampled fishery discards in the fishing grounds of Palamós (the main harbour for this fishery on the Catalan margin), which are located in several areas of a submarine canyon. We found that the discard ratio in this fishery showed a marked seasonal variability, with a maximum in spring and a minimum in summer. Most of the discarded … Show more

“…Moreover, the exploration of deep habitats and ecosystems under the European Framework Directive for the Marine Strategy will report additional new occurrences and species. Accurate faunistic analysis of fishery discards may also become an increasing source of biodiversity knowledge that may help to understand biogeographic patterns and dynamic changes in distribution, including early detection of allochtonous and invasive species (Gorelli et al 2016, Anjos et al 2018. Another interesting and necessary activity, which is also carried out in some areas, is the study of meroplanktonic larvae in relation to hydrographic currents and climate change, because it improves knowledge of specific composition and biocenoses, and can explain the presence of new records and the increase of the biogeographical range of some species (Torres 2015, Landeira et al 2017, Landeira and Lozano-Soldevilla 2018.…”

“…The mean effective towing duration was 1 hour 40 minutes. Catch sampling focused on A. antennatus, which is the only target species in this fishery and constitutes the majority of the catches (Gorelli et al 2016b). The CL of individuals in the codend and cover was measured with a precision of 0.1 mm.…”
