A new study suggests that more than 40 fish species in the Mediterranean could vanish in the next few years. The study released Tuesday by the International Union for Conservation of Nature says almost half of the species of sharks and rays in the Mediterranean and at least 12 species of bony fish are threatened with extinction due to overfishing, pollution and the loss of habitat.
Commercial catches of bluefin tuna, sea bass, hake and dusky grouper are particularly threatened, said the study by the Swiss-based IUCN, an environmental network of 1,000 groups in 160 nations.
"The Mediterranean and eastern Atlantic population of the Atlantic bluefin tuna is of particular concern," said Kent Carpenter, IUCN's global marine species assessment co-ordinator.
He cited a steep drop in the giant fish's reproductive capacity due to four decades of intensive overfishing. Japanese diners consume 80 per cent of the Atlantic and Pacific bluefins caught and the two tuna species are especially prized by sushi lovers. (read more)
