Sponge assemblages in fishing grounds and seamounts of the Balearic Islands (western Mediterranean)

The Balearic Archipelago (western Mediterranean) is an area of great ecological interest due to the combination of complex geomorphology, highly oligotrophic waters and low fishing pressure. Sponges play a key role in benthic habitats, providing structural complexity and significantly contributing t...

Sponges play a key role in benthic habitats, providing structural complexity and significantly contributing to their diversity and biomass. Here, we present an insight into the sponge communities of this archipelago from the analysis of samples collected during several scientific research surveys carried out on bottom trawl fishing grounds around the Balearic Islands and on sedimentary and rocky bottoms of the Mallorca Channel seamounts. Sampling was carried out with experimental bottom trawl, beam trawl, rock dredge and remotely operated vehicle (ROV). We analyzed species presence/absence data using multivariate methods in order to identify assemblages. Once identified, we characterized their biodiversity, biomass and taxonomic composition. A dbRDA analysis was conducted to test the influence of environmental variables and fishing pressure on the sponge communities. Up to 350 species are reported: 220 at bottom trawl fishing grounds and 189 at seamounts. Communities were structured by depth, temperature, currents, substrate and fishing pressure with sponge presence/absense, biomass and diversity also linked to the presence of deep algae beds. Taxonomic composition differed between bottom trawl fishing grounds and the seamounts, where this fishing activity is almost negligible, pointing to different sensitivity to this fishing impact among the different orders, particularly for Tetractinellida, which was much more diverse and abundant at seamounts.This research was performed in the scope of the LIFE IP INTEMARES project, coordinated by the Biodiversity Foundation of the Spanish Ministry for the Ecological Transition and the Demographic Challenge. It receives financial support from the European Union's LIFE program (LIFE15 IPE ES012). The MEDITS surveys are co-funded by the European Union through the European Maritime and Fisheries Fund (EMFF), being included in the National Program of collection, management, and use of data in the fisheries sector and support for scientific advice regarding the Common Fisheries Policy (Data Collection Framework). CIRCA-LEBA survey is part of the project 18-ESMARES2-CIRCA, included in the program “Asesoramiento científico-técnico para la protección del medio marino: Evaluación y seguimiento de las Estrategias Marinas, Seguimiento de los espacios marinos protegidos de competencia estatal (2018–2021)”, co-funded by Spanish Ministry for the Ecological Transition and the Demographic Challenge.
