Where Are All the Dolphins?
Worrying news from Europe on the lack of cetaceans (whales and dolphins) in the Bay of Biscay this summer. Researchers from the wildlife conservation group Marinelife have been conducting scientific surveys of whales, dolphins and seabirds in the English Channel and Bay of Biscay every month for the last 13 years. All told they've counted more than 20 cetacean species and more than a hundred thousand animals. However, as Science Daily reports, this summer is proving alarmingly different. The three main dolphin species, Common Dolphin, Striped Dolphin and Bottlenose Dolphin, are down ~80% from last year. Seabirds — auks, shearwaters, and gannets — are also largely absent. The year is also marked by a collapse of the anchovy fishery — such that fishing bans are in place for the Spanish and French fleets. The researchers worry this reduction in fish stocks, which may be due to overfishing, may also be linked to climate change (read MoJo's The Last Days of the Ocean package for more on these issues). Furthermore, dolphins in these waters are frequent bycatch victims of the fishing fleets, with thousands dying each year in the nets, and many of them washing up dead on the beaches. . . Well, there's a lovely way to start your summer holiday, on a beach devoid of any living thing but loaded with the sad carcasses of dead dolphins. Can we get a louder SOS from the ocean?
