Back in September 2006 I blogged about salmon farming and how the fish were given chemicals to achieve the level of colour that they got naturally by eating krill and wondered how long before it was realized it was cheaper to feed them the krill.
It wasn't long. Antarctic krill is already being overharvested to feed farmed salmon. Krill are tiny shrimp like creatures and are the staple diet of polar marine animals including penguins and whales. The krill are already under threat with the loss of the sea ice and parts of the ice shelf which forms the krill nursery.
The US National Enviromental Trust says fishing-industry figures indicate that a catch of 746,000 tonnes will be made n the coming season, 25 per cent above the quota set by the Commission for the Conservation of Antarctic Marine Living Resources.
The krill eat phytoplankton, everything else eats krill or the creatures that feed on krill. It's all about balancing the environmental ecosystems that exist in polar waters. I'm all for stopping whale hunts but we also have to take a good look at the smaller picture.
