The chain pickerel (Esox niger) is a species of freshwater fish in the pike family (family Esocidae) of order Esociformes.{{FishBase_species|genus=Esox|species=niger|year=2004|month=October}} The chain pickerel and the American pickerel (E. americanus) belong to the Esox genus of pike.

Taxonomy

French naturalist Charles Alexandre Lesueur described the chain pickerel in 1818. Its species name is the Latin word niger "black".{{cite encyclopedia |url=http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0059%3Aentry%3Dniger1 |title=nĭger |encyclopedia=A Latin Dictionary|last1=Lewis|first1=Charlton T.|last2=Short|first2=Charles|access-date=10 December 2022|year=1879|publisher=Clarendon Press|location=Oxford|via=Perseus Digital Library}}

Nicknames include the "southern pike", "grass pike", "jack", "jackfish", "gunny" and "eastern pickerel". In central Florida the chain pickerel is known locally as "Gatorfish" {{cite web |url=https://nas.er.usgs.gov/queries/factsheet.aspx?SpeciesID=681|title=Esox niger (Chain Pickerel)|website=Nonindigenous Aquatic Species|publisher=U.S. Geological Survey|last1=Fuller|first1=P.|last2=Larson|first2=J.|last3=Makled|first3=T.H.|last4=Lower|first4=E.|last5=Fusaro|first5=A.|date=12 September 2019|orig-date=Peer reviewed 30 January 2015|access-date=20 January 2023}}

Description

The chain pickerel has a distinctive, dark, chain-like pattern on its greenish sides. There is a vertical dark marking underneath the eye, which helps to distinguish the chain pickerel from redfin pickerel (Esox americanus americanus) and grass pickerel (E. americanus vermiculatus), in which the mark curves posteriorly.{{cite web |last=Kirk|first=Jacob|title=Chain Pickerel (Esox niger)|url=https://www.cfr.msstate.edu/wildlife/fisheries/?a=detail&id=70&info=|publisher=Mississippi State University|website=Fishes of Mississippi|access-date=11 December 2022|date=11 December 2022}} Its body outline resembles that of the northern pike (E. lucius). Unlike northern pike, however, the opercles and cheeks of chain pickerel are entirely scaled. It may reach up to {{convert|78.7|cm|in}} long only on rare occasions. The average size for chain pickerel, however, is 24 in (61 cm) and 3 lb (1 1/2 kg). (The average chain pickerel caught by fishermen is under 2 lb). It lives around 8 yr. In some places{{where|date=December 2022}} the pickerel is known as a "gunfish", "gunny" or "slime dart",{{citation needed|date=December 2022}} due to its characteristic slime coating.{{Cite web|url=https://www.lohud.com/story/sports/columnists/2014/05/19/outdoors-time-target-pickerel/9312245/|title=Outdoors: It's time to target pickerel|access-date=10 December 2022|last=Sapir|first=Glenn|date=19 May 2014|website=lohud.}}

A blue color morph lacking the usual reticulated pattern has been described in a New York population.{{cite journal |last1=Menzel|first1=Bruce W.|last2=Green Jr.|first2=David M.|title=A Color Mutant of the Chain Pickerel, Esox niger LeSueur|journal=Transactions of the American Fisheries Society|doi=10.1577/1548-8659(1972)101<370:ACMOTC>2.0.CO;2|pages=370–372|volume=101|issue=2|year=1972}}

Distribution

File:Esox niger map.svg Its range is along the eastern coast of North America from southern Canada to Florida, and west to Texas. In the New England, the species occurs in Maine and New Hampshire. The fish inhabits fresh and brackish water from the Mississippi Valley. It also is commonly found in Lake Michigan and the lower portion of the Great Lakes.Pike, Pickerel and Muskalonge, Alfred C. Weed, Zoology Leaflet 9, Field Museum of Natural History, Chicago, Illinois, 1927, pg. 19. In the Canadian Maritimes, chain pickerel is known from New Brunswick and Nova Scotia.

Chain pickerel is considered an invasive species in Nova Scotia, where native fish stocks have been severely impacted by the effects of its introduction, primarily through its role as a voracious predator.{{Cite web|url=https://nsinvasives.ca/chain-pickerel/|title = Chain Pickerel - Nova Scotia Invasive Species Council|date = 2025-05-15}} Historical angling destinations in the province's mainland, like Kejimkujik National Park, have been heavily impacted by the illegal introduction of this fish to the area.{{Cite web |last= |first= |date=2025-03-24 |title=Fishing |url=https://parks.canada.ca/pn-np/ns/kejimkujik/activ/peche-fishing |access-date=2025-03-24 |website=parks.canada.ca}}

Habitat

Chain pickerel live in a variety of habitats, including pools within creeks or rivers,{{cite web |url=https://dwr.virginia.gov/wildlife/fish/chain-pickerel/|title=Chain Pickerel|website=Virginia Department of Wildlife Resources|access-date=10 December 2022|year=2022}} lakes with vegetation cover, swamps and other wetlands.{{cite web |url=https://www.chesapeakebay.net/discover/field-guide/entry/chain-pickerel|title=Chain Pickerel|website=Chesapeake Bay Program|access-date=10 December 2022|year=2022}} Chain pickerel are tolerant of brackish water with salinity levels of up to 22 ppt. They are also acid tolerant to a pH of 3.8.

Diet

Like the northern pike, the chain pickerel feeds primarily on smaller fish, until it grows large enough to ambush large fish from cover with a rapid lunge and to secure it with its sharp teeth. Chain pickerel are also known to eat frogs, snakes,{{cite web |url=https://animaldiversity.org/accounts/Esox_niger/ |title = Esox niger Pickerel|website=Animal Diversity Web|last=Shelburne|first=Jacob|archive-date=8 October 2022|archive-url=https://web.archive.org/web/20221008020620/https://animaldiversity.org/accounts/Esox_niger/|url-status=live|editor-last1=Powers|editor-first1=Karen|editor-last2=Atwood|editor-first2=Alex|editor-last3=Dameron|editor-first3=Marisa|editor-last4=Hammond|editor-first4=George|year=2017}} worms, mice, other small mammals, crayfish, insects, and a wide variety of other foods.{{cite book|last=Sternberg|first=Dick|title=Freshwater Gamefish of North America|year=1987|publisher=Cy DeCosse Incorporated|isbn=0-86573-023-7}} It is not unusual for pickerel to leap out of the water at flying insects, or even at dangling fishing lures.{{Cn|date=February 2021}} Raney (1942) studied chain pickerel in a New York pond and found that golden shiners were found in the stomachs of 47.3% of the 234 chain pickerel examined. Brown bullheads were found in 13.8%, and pumpkinseed sunfish were found in 13.2%. Crayfish of the genus Cambarus were present in 42% of the chain pickerel.{{cite journal |title=The Summer Food and Habits of the Chain Pickerel (Esox niger) of a Small New York Pond|last=Raney|first=Edward C.|journal=The Journal of Wildlife Management|volume=6|issue=1|year=1942|pages=58–66|jstor=3795522|doi=10.2307/3795522}}

Reproduction

Spawning occurs in flooded vegetation at the end of winter or beginning of spring when the water temperature is between {{convert|2|-|22|C|F}}. A secondary fall spawning has been reported in Pennsylvania.{{cite book|last=Ross|first=Stephen T.|title=Inland Fishes of Mississippi|year=2001|publisher=Mississippi Department of Wildlife, Fisheries and Parks|isbn=1-57806-246-2|pages=336–338}}{{cite journal |last=Miller|first=Jack G.|year=1962|journal=Transactions of the American Fisheries Society|volume=91|issue=3|pages=323|doi=10.1577/1548-8659(1962)91[323:OORCPI]2.0.CO;2|title=Occurrence of Ripe Chain Pickerel in the Fall}} Fertilization is external and eggs and sperm are mixed by the adults' tail movements.{{cite journal|last=Armbruster|first=Daniel C.|title=Observations on the Natural History of the Chain Pickerel (Esox niger)|journal=The Ohio Journal of Science|volume=59|issue=1|pages=55–58|year=1959|hdl=1811/4599 |url=http://hdl.handle.net/1811/4599|access-date=11 December 2022|issn=0030-0950}} Up to 50,000 eggs may be released by the female. No parental care is provided, and the eggs hatch between six and twelve days after they are laid. The fry possess adhesive glands on their snouts that they use to attach to vegetation.{{cite journal|last=Underhill|first=A.H.|title=Studies on the Development, Growth and Maturity of the Chain Pickerel, Esox niger Lesueur|journal=The Journal of Wildlife Management|volume=13|issue=4|year=1949|pages=377–391|doi=10.2307/3795630|jstor=3795630}} It takes six to eight days for the fry to absorb their yolk sac, at which point they begin to actively hunt.

Angling

The chain pickerel is a popular sport fish. It is an energetic fighter when hooked. Anglers have success with live minnows, spinnerbaits, spoons, topwater lures, plugs, and flies, usually tied with some kind of feather or bucktail material.{{cite web |title=Pickerel Fishing Tips |url=https://www.riversearch.com/site/how-to-catch-pickerel-fishing-tips.html |website=Riversearch |date=14 March 2020 |access-date=7 April 2020}} If the angler intends to release a fish, it is advisable use pliers to flatten the barbs on the lure's hooks. Chain pickerel can swallow an entire lure, so it will be much easier to free a deeply hooked fish and get it back into the water as soon as possible.{{Cn|date=February 2021}}

Practically any bass lure can be effective for pickerel, although like most pike, they seem to be particularly susceptible to flashy lures which imitate small forage fish. Dragging a plastic worm, lizard, frog, or other soft imitation can also be extremely effective. A Texas rig method is recommended with these soft baits for productive fishing in the weeds.{{Cn|date=February 2021}}

A steel leader is necessary for sharp-toothed and active fish at two to three pounds. The angler would also do well to use 12- to 17-lb-test line on an open-faced spinning reel. Methods are similar to those for bass, such as dragging a lure through weeds in shallow water and jerking it side-to-side to give it the look of injured prey. Chain pickerel are voracious and opportunistic feeders, and will attack most any fodder that moves into their range of vision.{{Cn|date=February 2021}}
