The Northern pike, Esox lucius, is a carnivorous fish of brackish and freshwaters of the northern hemisphere. It is also known by the somewhat misleading folk-name, “water wolf”.
E. lucius is found throughout the northern hemisphere, including Russia, Europe, the British Isles, and North America.
Within North America, there are Northern pike populations in eastern New York, northern New England, most of Canada (though pike are rare in British Columbia), Alaska, the Ohio Valley, the Great Lakes basin and surrounding states, Missouri, and Nebraska. They may be stocked in some western lakes and reservoirs as game fish.
Northern pikes are most often olive, shading into yellowish or whitish on belly with short, light bar-like spots on body and some dark spots on the fins. The lower half of their gill cover lacks scales and they have large pores on their head and lower jaw. Unlike the similar-looking Muskellunge, the Northern pike has light markings on a dark body background and less than six pores on the underside of its jaw.
Pike grow to a relatively large size: lengths of (150 cm) and weight of (25 kg) are not unheard of. The largest specimen to date was caught in an abandoned stone quarry, in Germany, in 1983. She was 4.8 feet long and weighed 67 lb. The longest pike was 5 feet long and weighed 60.6 lb. There were reports in older days of giant pikes of up to 91.5 lb, in particular from Ireland, most of which were researched by Fred Buller and published in “The Doomsday Book of Mammoth pike”, supposedly caught in nets at the end of the 1800s. The British Islands have not managed to produce much in the way of giant pikes in the last 50 years or so however, wherefore there is much doubt surrounding those claims. Currently, the IGFA recognizes a 55 lb, 1 oz (25.5 kg) pike caught by Lothar Louis in Lake of Grefeern, Germany on October 16, 1986 as the all-tackle Northern Pike world record. Northern Pikes in North America seldom reach the size of their European counterparts, however, one of the largest being a 46 lb specimen from New York state. There are reports of far larger pike, but these are either misidentifications with its much larger relative the muskellunge, or simply have not been properly documented and belong in the realm of legend.
Northern pike occasionally breed with muskellunge to produce the hybrid commonly known as the Tiger Muskellunge (Esox masquinongy x lucius or Esox lucius x masquinongy, depending on the gender of each of the contributing species). In the hybrids, the males are almost invariably sterile although the females are sometimes fertile. Another form of Northern pike, the Silver pike, is not a subspecies but rather a mutation that occurs in scattered populations. Silver pike, sometimes called Silver Muskellunge, lack the rows of spots and appear silver or silvery-blue in color.
Pikes are found in sluggish streams and shallow, weedy places in lakes, as well as in cold, clear, rocky waters. The pike generally hides in wait for prey, holding perfectly still for long periods, and is then capable of remarkable acceleration, sometimes propelling it a meter into the air (though it rarely leaves the surface). It catches its prey sideways with its sharp teeth, in order to kill it, before turning lengthwise to swallow. It eats mainly fish, but on occasion water voles and ducklings have also been known to fall prey to pike. It is moreover a cannibal and this cannibalism serves in maintaining stability in the pike population. Young pike have been photographed eating pike of a similar size. Northern Pike also feed on others of their kind, insects, and leeches. It has a tremendous appetite.
Importance to humans
While a worthy adversary for any rod and line fisherman, pike are often caught and released by fishermen since its flesh is bone-filled. However, the larger fish can be filleted, and pike have had a long and distinguished history in cuisine and are popular in Germany, with historical references to its cooking going back as far as the Romans. Pike have very white, mild flesh, and are considered among the best tasting freshwater fish. When eating pike, be sure to chew carefully, as their “y-bones” are not always easily visible.
Fishing for pike is said to be very exciting with their explosive hits and aerial acrobatics. The pike are some of the biggest freshwater fish.
The Northern pike gets its name from its North American habitat and its resemblance to the pole-weapon known as the pike (Esox also means “pike”). It’s also known as the American pike, common pike, great northern pike, Great Lakes pike, grass pike, pickerel, snake, northern, and jackfish.
