(Very) long‐term transport of Silurus glanis, Charcharhinus melanopterus, Scomb...

In this paper, we cover 4 years of live fish transports that ranged from 14 to 200 h (8 days), and bioloads from 3.8 to 76.9 kg/m3. The key ingredients for success in all trips, where virtually no mortality occurred, was atributed to (1) pre‐buffering the water with sodium bicarbonate and sodium carbonate at 50 g/m3 (each)—and/or ATM Alka‐HaulTM at 25 g/m3—and applying additional (partial or full) doses through...

Dense cold‐water coral garden of paragorgia johnsoni suggests the importance of...

Mid-ocean ridges generate a myriad of physical oceanographic processes that favor the supply of food and nutrients to suspension- and filter-feeding organisms, such as cold-water corals and deep-sea sponges. However, the pioneering work conducted along the Mid-Atlantic Ridge failed to report the presence of large and dense living coral reefs, coral gardens, or sponge aggregations. Here, we describe the densest,...

Deep-sea misconceptions cause underestimation of seabed-mining impacts

Scientific misconceptions are likely leading to miscalculations of the environmental impacts of deep-seabed mining. These result from underestimating mining footprints relative to habitats targeted and poor understanding of the sensitivity, biodiversity, and dynamics of deep-sea ecosystems. Addressing these misconceptions and knowledge gaps is needed for effective management of deep-seabed mining.

The effect of rapid decompression on barotrauma and survival rate in swallowtai...

Swallowtail seaperch, Anthias anthias, is a popular fish in the public aquaria industry worldwide, but is subject to barotrauma and high mortality rates if an appropriate decompression profile is not used. Here, we analyze behavioral response to pressure reductions in swallowtail to define protocols for mitigating surfacing mortality. Four different pressure reduction rates were tested (15%, 25%, 35%, and 45%) ...

Capture, husbandry and long-term transport of pilotfish, Naucrates ductor (Linn...

This is a report on the capture, transport, and husbandry of pilotfish, Naucrates ductor. The objective of this work was to evaluate the most adequate process for capturing, transporting and maintaining pilotfish, while gaining understanding on their behavior. Collection was done in the Azores, by hook and line. Seventy six individuals were then transported to shore, where they were maintained for two months. A...

Potential Mitigation and Restoration Actions in Ecosystems Impacted by Seabed M...

Mining impacts will affect local populations to different degrees. Impacts range from removal of habitats and possible energy sources to pollution and smaller-scale alterations in local habitats that, depending on the degree of disturbance, can lead to extinction of local communities. While there is a shortage or even lack of studies investigating impacts that resemble those caused by actual mining activity, th...

Historical gene flow constraints in a northeastern atlantic fish: Phylogeograph...

The distribution and demographic patterns of marine organisms in the north Atlantic were largely shaped by climatic changes during the Pleistocene, when recurrent glacial maxima forced them to move south or to survive in northern peri-glacial refugia. These patterns were also influenced by biological and ecological factors intrinsic to each species, namely their dispersion ability. The ballan wrasse (Labrus ber...
