Arctic Cod

Описание: For the first time in North America, Vancouver Aquarium's team of biologists successfully hatched and reared several hundred Arctic cod to the juvenile stage. Our researchers believe that this significant breakthrough in the controlled breeding of Arctic cod will have beneficial research implications for the species.

Why is this research so important? Arctic cod are a key link in the Arctic food chain. They are a primary food source for iconic species such as narwhals, belugas and ringed seals, which polar bears depend upon for their survival, and Inuit communities rely on them as well. Arctic cod are also preyed upon by Arctic char, Greenland halibut, Atlantic salmon and Atlantic cod. The health of Arctic cod populations is a clear indication of the overall health of the Arctic ecosystem.
