An overview is proposed of the hexactinellid sponge fauna of the Mediterranean Sea, including the description of a new species of Sympagella, S. delauzei sp. nov., collected by ROV during the exploration of deep-sea canyons of the NW Mediterranean and of deep banks and seamounts of the Alboran Sea. The type species of Sympagella, S. … Read more
Isidella elongata is a candelabrum-shaped alcyonacean forming important facies on the bathyal muddy bottoms of the Mediterranean Sea, currently considered a sensitive habitat and heavily impacted by deep-sea fisheries. Until a few decades ago, this facies was a widespread habitat of the deep Mediterranean seabed and I. elongata was a common species in the trawling … Read more
The advent of deep-sea exploration using video cameras has uncovered extensive sponge aggregations in virtually all oceans. Yet, a distinct type is herein reported from the Mediterranean: a monospecific reef-like formation built by the lithistid demosponge Leiodermatium pfeifferae. Erect, plate-like individuals (up to 80 cm) form bulky clumps, making up to 1.8 m high mounds … Read more
Europe has a long tradition of exploiting marine fishes and is promoting marine economic activity through its Blue Growth strategy. This increase in anthropogenic pressure, along with climate change, threatens the biodiversity of fishes and food security. Here, we examine the conservation status of 1,020 species of European marine fishes and identify factors that contribute … Read more

Recent ROV surveys of deep-sea areas around the Maltese Islands resulted in the discovery of highly diverse habitats, including extensive rocky areas dominated by living cold water corals and gorgonians at depths of 300–1000 m, a sub-fossil lithistid sponge reef at a depth of ca. 300 m, deep-water caves located at 270–450 m, and vast … Read more
For effective fisheries management to be able to act, realistic fisheries removal data are needed, so as to assess exploitation levels and the impact of fisheries on the ecosystem. Unfortunately, official statistics underestimate catches in most countries and regions. In the Balearic Islands (Western Mediterranean), where artisanal fishing and industrial bottom trawling are the most … Read more
Management of fisheries in the Mediterranean basin has often been described as a unique and complex challenge, due to their multi-specificity, the diversity of gear-types, and the number of nations involved. This perspective has gone hand-in-hand for decades with a lack of strong political will from decision-makers, who have been unwilling to put Mediterranean fisheries … Read more
What is an Essential Fish Habitat? An Essential Fish Habitat (EFH) is a habitat identified as crucial to the ecological and biological requirements for the critical life cycle of exploited fish species, and which may require special protection to improve stock status and long-term sustainability. In particular, EFH refers to the waters and substrate necessary … Read more
The European Union is failing to responsibly manage its fish resources. Despite several international commitments and EU framework regulations on sustainable fisheries, the status of fish stocks is still far from being considered as healthy. Overfishing in the EU continues to affect a large proportion of fish stocks. In the North Western Waters (NWW) the … Read more
