Sea Shepherd Australia has launched a new campaign to protect a species much smaller than the whales it has generally focused on, but just as important to the Southern Ocean ecosystem.
Krill play a crucial role in the Antarctic food chain, as they are consumed by whales, penguins and various other seabirds. The Southern Ocean is not only cold, but also remote and barren, meaning the vast swarms of 5cm-long crustaceans are the basis of the marine food chain. A single humpback whale, for example, will consume around a tonne, almost exclusively krill, every day.
But now corporate interests have the krill in their sights. The species is the new fad, identified as containing a cheap source of protein, and it has even gained the moniker 'pink gold'.
"It's this boom time in terms of harvesting krill. It's seen as this very cheap protein to feed fish farms, to feed the cattle feedlots, and to feed the supplement market," says Adam Burling, media spokesperson for Sea Shepherd Australia.
Blackmores Ltd is a giant in the Australian health supplement industry. Its products are also sold in New Zealand. Blackmores has taken to producing omega-3 pills called 'EcoKrill', which, Sea Shepherd asserts, is anything but.
