Nothern pike

Esox lucius

The northern pike (Esox lucius, known simply as a pike in Britain, Ireland, and the USA, or as jackfish in Canada), is a species of carnivorous fish of the genus Esox (the pikes). They are typical of brackish and freshwaters of the northern hemisphere.

Northern pike are most often olive green, shading from yellow to white along the belly. The flank is marked with short, light bar-like spots and there are a few too many dark spots on the fins. Sometimes the fins are reddish. Younger pike have yellow stripes along a green body, later the stripes divide into light spots and the body turns from green to olive green. The lower half of the gill cover lacks scales and they have large sensory pores on their head and on the underside of the lower jaw which are part of the lateral line system. Unlike the similar-looking and closely related muskellunge, the northern pike has light markings on a dark body background and fewer than six sensory pores on the underside of each side of the lower jaw.

Pike grow to a relatively large size; lengths of 150 centimeters and weights of 25 kilograms are not unheard of. The heaviest specimen known so far was caught in an abandoned stone quarry, in Germany, in 1983. She (the majority of all pikes over 8 kg are females) was 147 cm long and weighed 31 kg. The longest pike ever recorded was 152 cm long and weighed 28 kg.
