Study says sharks/rays globally overfished

One quarter of the world’s cartilaginous fish, namely sharks and rays, face extinction within the next few decades, according to the first study to systematically and globally assess their fate. The International Union for Conservation of Nature’s Shark Specialist Group, co-chaired by Nick Dulvy, a Simon Fraser University Canada Research Chair in Marine Biodiversity and Conservation in British Columbia, conducted the study. It was published in eLife journal today.
