Elasmobranchs of the Mediterranean and Black Sea
In many fisheries they are, however, often landed and marketed.
Marine Ecology
During the last decades, aquatic resources have been severely depleted due to human-induced factors such as overexploitation and pollution and more recently due to deviations in the physicochemical parameters of oceans, dramatic changes in weather patterns and melting of glaciers. The effects of these man-made factors are occurring in a relatively shorter time scale and, in many cases, are beyond the capacity of organisms to adapt to these deviations. The majority of natural aquatic resources, which are one of the most important food sources on the planet, are being used to the extent that limits their capacity for regeneration. Despite ongoing attempts towards developing strategies for long...

Sharks,Äô Status in the Mediterranean Sea Urgent Awareness is Needed
Cartilaginous fishes are a very ancient group; Sharks have lived on Earth for about 500 million years, since long before the dinosaurs. They have been able to survive and overcome five mass extinctions since their appearance. They play in fact a key role in maintaining the balance of marine ecosystems. More than 97% of the shark population has disappeared in the last two centuries. Currently, a high percentage is threatened, many are data-deficient. Many menaces face sharks, but fishing pressure seems to be most critical. This chapter focuses on the current status of cartilaginous fishes and progress on conservation measures and actions taken mainly through regional plans.

Organized by the GFCM at FAO headquarters, Rome, Italy, from 10 to 14 December 2018, in collaboration with technical partners, the Fish Forum 2018 is a first-of-the-kind event gathering scientists, researchers, engineers, academics, practitioners, managers and decision-makers from around the world to discuss and share knowledge on the latest developments in fisheries science. The material contained in this book of abstracts stems from the contributions received from particip...
Das Mittelmeer
Dieses nahezu vollständig überarbeitete und um zwei gänzlich neue Kapitel erweiterte Werk ist weit mehr als nur eine 2. Auflage. Denn in den letzten 20 Jahren haben Herausgeber und Mitautoren viel Neues und Verblüffendes über das Mittelmeer erfahren. Eine neue Wissenschaft hat sich formiert, die multidisziplinäre Mediterranistik, die dank Historikern neue Einsichten zum Verständnis dieses Raums ermöglicht. Doch auch die Umweltforschung machte große Fortschritte und fördert Beunruhigendes an den Tag: Die negativen Veränderungen im Mittelmeer und im mediterranen Raum laufen heute in einer Geschwindigkeit ab, die es in der Erdgeschichte bisher wahrscheinlich noch nie gegeben hat. Die...
