European fisheries have traditionally exploited many small bottom-living coastal sharks and rays, and have recently increased their exploitation of pelagic and deep-water sharks.For stock assessments that rely on catch data, it is essential to quantify the total removals of the stocks of concern. Oceana would like to take this opportunity to provide an update on … Read more
Elasmobranches, the group of fishes that include sharks and batoids (rays and other flat sharks), are found in all European waters, from the cold and deep waters of Greenland to the warm subtropical waters of the Canary Islands. Elasmobranches are cartilaginous fishes, meaning they have skeletons made of cartilage instead of bone; they present a … Read more
Sharks represent one of nature’s most successful creations. They have roamed our oceans for over 400 million years and survived various extinction events to evolve into predators that are perfectly adapted to the marine environment. Early sharks looked very different from today’s modern sharks, but these animals have always had a strategic advantage over their … Read more
Most of large pelagic species like tuna, sharks and swordfish are overfished in the Atlantic Ocean and Mediterranean Sea, due to the extremely high prices their meat or fins can reach in most of world’s markets. Bluefin tuna is on the verge of collapse due to overfishing, mismanagement and illegal fishing, Sharks are extremely vulnerable … Read more
According to conventional wisdom, small, fast-growing fish are impossible to overfish because their populations are so large and grow so quickly. Yet we are now seeing disquieting signs that conventional wisdom is wrong. Most significantly, scientists are reporting ocean predators emaciated from lack of food, vulnerable to disease and without enough energy to reproduce. Scrawny … Read more
Sharks have been fished for hundreds of years, some records even date back to ancient Roman times. But it has only been in the last few decades when the volume of shark catches increased exponentially. Sharks are now targeted by both highly industrialised fishing fleets and artisanal fisheries. Sharks are mainly hunted for their fins … Read more
Protecting marine species worldwide is difficult and requires specific actions to be developed or adapted. Countries are authorised to protect only an extremely small proportion of the habitats in which these species live. As such, the development of isolated policies or policies based on geographic limitations makes measures less effective. In addition, agreements or legislation … Read more
Sharks, rays and chimaeras make up the group of fish known as Chondrichthyans– these fish all have skeletons made of cartilage rather than bone. In general, Chondrichthyans grow slowly, mature late and produce few young over long lifetimes. Consequently, their populations grow at extremely low rates, leaving them exceptionally susceptible to fisheries overexploitation and slow … Read more
Red calcareous algae have been widely studied in the shallow waters of the Western Mediterranean (Ballesteros, 2006), but there is very little information about their distribution and function in deep areas. Two main infralittoral and circalittoral ecosystems created by calcareous red algae have been mentioned: maërl and coralligenous beds (Pérès & Picard, 1964; Picard, 1965). … Read more
In 2008, Oceana and MarViva collaborated in a campaign to definitively eliminate the use of driftnets in the Mediterranean. Banned by the United Nations more than 15 years ago, this gear is still being used and constitutes a serious threat for cetaceans, turtles and sharks. This fishery mainly targets the already overexploited swordfish stock which … Read more
