Forty Species of Fish in Mediterranean May Soon Vanish

1x1.trans Forty Species of Fish in Mediterranean May Soon VanishAccording to a study funded by the International Union for Conservation of Nature (IUCN), a global conservation network and leading authority on the environment and sustainable development, more than 40 species of marine fish currently found in the Mediterranean could disappear in the next few years.

Nearly half of the species of sharks and rays and at least 12 species of bony fish are threatened with extinction due to overfishing, marine habitat degradation and pollution. Commercial species like Bluefin Tuna, Dusky Grouper, and Sea Bass are considered threatened or with extinction at the regional level.

There has been an estimated 50% decline in this species’ reproduction potential over the past 40 years due to intensive overfishing,” says Kent Carpenter, IUCN Global Marine Species Assessment Coordinator.

“The lack of compliance with current quotas combined with widespread underreporting of the catch may have undermined conservation efforts for this species in the Mediterranean.”

Because of the illegal use of driftnets and use of trawling nets, hundreds of marine animals with no commercial value are captured — sharks, rays, whales, turtles and birds — imperiling their population numbers.

“The use of trawling nets is one of the main problems for conservation and sustainability of many marine species,” says Maria del Mar Otero, IUCN-Med Marine Program Officer.

The report also highlights the lack of information on the conservation status of nearly one third of these Mediterranean marine fish, a significant proportion of which are considered endemic to the region. Researchers speculate that the “Data Deficient” group could in fact include a large proportion of threatened fish.

In the past 40 years, Bluefin tuna populations everywhere have declined by 80 percent due to industrialized overfishing. And the threat to bluefin survival extends beyond even the Gulf oil spill.

Moreover, because tuna cross so many boundaries, even when tuna do leave the high seas and tarry in any one nation’s territorial waters (as Atlantic bluefin usually do), they remain under the foggy international jurisdiction of poorly enforced tuna treaties.”
