General Description
This General Description has not been written yet.
A highly regarded freshwater game fish, hard-fighting great northern pike, sometimes called jackfish, are found in most lakes and rivers in mainland Northwest Territories. They prefer warmer water; slow, heavily-vegetated rivers, or weedy bays.
The American, northern, or great northern pike, Esox lucius, called jackfish in Canada, is also voracious, lurking in weedy shallows to ambush its prey.
Bird: Unlike the Brown Pelican, the American White Pelican does not dive for its food. Instead it practices cooperative fishing. Each bird eats more than 4 pounds of fish a
day, mostly carp, chubs, shiners, yellow perch, catfish, and jackfish.
