Northern Pike (Jackfish)
What do we know about northern pike?
Northern pike, also called jackfish, can be found throughout mainland Northwest Territories. They like weedy areas of warm lakes and slow rivers. Northern pike are dark green and brown with lighter spots along their sides. They are known for their sharp teeth!
Northern pike, like most other fish species, often contains some mercury. Mercury is a heavy metal contaminant that can build up in the organs and in the meat.
Northern pike eat other fish and are high in the food chain. Fish that eat other fish tend to have higher levels of mercury due to a process called biomagnification. As well, older fish tend to have higher levels of mercury than younger fish due to a process called bioaccumulation. This does not necessarily mean that they are unsafe to eat.
Northern pike is good for us!
Northern pike is an excellent source of protein. Protein is needed to build and repair all parts of the body.
Northern pike is rich in several other important nutrients, including selenium, vitamin D, vitamin B-12, and niacin. These nutrients have many different functions and they are all required to keep the body healthy. When sunshine hits your skin, your body can make its own vitamin D but in the winter when the sunshine is limited, it is important to eat foods that provide this vitamin for us, like northern pike.
