Factory fishing in Antarctica for krill targets the cornerstone of a fragile ecosystem

ABOARD THE ALLANKAY off Antarctica (AP) — Fishing for krill is banned in U.S. waters due to concerns it could impact whales, seals and other animals that feed on the shrimp-like creatures. But such fishing has been taking place for decades in Antarctica, where krill are most abundant. There’s surging demand for the nutrient-rich crustacean for feeding farm-raised fish, omega-3 pills, pet food and protein shakes. Advances in fishing combined with the still unknown impact from climate change on krill has some scientists warning the fishery is in urgent need of stricter controls.
