BREMERHAVEN, Germany, Oct. 13 (UPI) -- Polar cod are a vital food source for whales, narwhals, ringed seals and arctic seabirds, but researchers have had a hard time studying these fish and estimating their numbers.

That's now changing, thanks to new netting technology. Recently, a team of German researchers were able to catch a large number of polar cod living beneath the arctic sea ice. Their findings suggest billions of juvenile cod prefer the shelter of the arctic shelves and drifting sea ice.
