Fishing is one of the human activities with the highest impact on seabeds. During the past hundred years it has gradually expanded to deeper waters, and almost all continental shelf and slopes worldwide have now been fished to some extent. In EU managed fishing grounds between 200 and 1000 m depth, it is estimated that bottom trawling has impacted...

The negative effects from recurrent industrial fishing are widespread in the Mediterranean Sea waters, being the conservation status of the benthic ecosystems especially critical in the Catalan continental margin (NW Mediterranean Sea), which is identified as a hotspot of ecological importance due to the high concentration of endangered, threatened...
Article
Sea pens (Octocorallia, Pennatulacea) are a specialized and morphologically distinct group of octocorals. The majority of them have adapted to survive on soft sediments with the help of an anchoring muscular peduncle. The whip-like sea pen Protoptilum carpenteri is considered a deep-sea North Atlantic species, which recently has been documented als...
Article
Cold-water gorgonians dwelling on the continental shelf are a common by-catch of bottom-contact fishing practices. Given the slow growth and limited recruitment of cold-water gorgonians, the impact of fishing activities may seriously compromise the conservation of the highly complex coral gardens communities. For this reason, the development of eff...
