Esox niger Lesueur, 1818

Common Name: Chain Pickerel

Synonyms and Other Names:

southern pike, grass pike, jack, jack fish, eastern pickerel, gunny




Noel M. Burkhead - U.S. Geological SurveyCopyright Info

Identification: The chain pickerel is named for the dark chain-like patterns on its greenish sides, with a long, slim body somewhat resembling that of a northern pike. Further identification details can be found in Pflieger (1975); Page and Burr (1991); Etnier and Starnes (1993); Jenkins and Burkhead (1994).


Size: 99 cm


Native Range: Primarily the Atlantic slope from southwest Maine to southern Florida, but some populations exist above the Fall Line (Lee et al. 1980); Gulf Coast west to Sabine and Red drainages, Texas; Mississippi River basin north to Kentucky and Missouri (mostly Former Mississippi Embayment, but also upland streams in southeastern Missouri) (Page and Burr 1991). Hubbs et al. (1991) list as native to eastern Texas. For a detailed description of the distribution and range map, see Lee et al. (1980). Crossman (1978) also has a distribution map.


Great Lakes Nonindigenous Occurrences: Chain pickerel has been introduced into  Lake Huron, Potagannissing Bay near Rogg Island in Michigan (M. Ebner, pers. comm.); eastern Minnesota (Crossman 1978; Lee et al. 1980 et seq.); the Lake Erie drainage and the Adirondacks, Lake Ontario, Schroon Lake, and Piseco Lake in New York (Crossman 1978; Emery 1985; Lee et al. 1980; Smith 1985; Whittier et al. 2000; Cudmore-Vokey and Crossman 2000); many areas of Ohio (Trautman 1981; Burr and Page 1986; Hocutt et al. 1986), including Long Lake (Crossman 1978).

Ecology: Chain pickerel's preferred habitat includes vegetated lakes, swamps, and backwaters and quiet pools of creeks and small to medium rivers (Page and Burr 2011)This fish tolerates warm water, acidity to pH 3.8, and salinity to 22 ppt (Lee et al. 1980). It may enter brackish water in winter. Spawning occurs on flooded benches of streams, lakes, and ponds, where eggs sink and stick to the bottom or vegetation.

This species feeds primarily on smaller fish until it grows large enough to ambush larger prey from cover. Aggressive in their feeding habits, chain pickerel have been reported to eat a wide variety of bait, and are a popular sport fish that is an energetic fighter when hooked (Scott and Crossman 1973).


Means of Introduction: Intentional stocking in most areas; may have gained access to south Florida through artificial canals.


Status: Established in many areas. Reported from Kentucky.


Great Lakes Impacts: Current research on the environmental impact of Esox niger in the Great Lakes is inadequate to support proper assessment.

Realized:
Chain pickerel is capable of hybridizing and forming viable offspring with related species, including the redfin pickerel (Esox americanus) and northern pike (Esox lucieus), both present in the Great Lakes Basin (Herke et al. 1990, Scott and Crossman 1973). The consequences of this are unknown.

Potential:
It has been suggested that predation by or competition with chain pickerel could impact threatened or endangered species of Canada, including Atlantic whitefish (Coregonus huntsmani) and distinct forms of rainbow smelt (Osmerus mordax) (DFO 2006, 2011).

There is little or no evidence to support that Esox niger has significant socio-economic impacts in the Great Lakes.

Potential:
Speculation exists that the predation by chain pickerel could have a negative impact on some sport fishes, particularly native trout and other stocked salmonids (Brokaw 2008). Chain pickerel has been actively controlled in parts of Maine due to its reputation as a voracious feeder (Brokaw 2008).

There is little or no evidence to support that Esox niger has significant beneficial effects in the Great Lakes.

Realized:
Chain pickerel is a popular sport fish in some parts of the Northeast (especially in the winter). In the Great Lakes and Canada, it is of minor importance to recreational fishing overall, although it is often kept if caught. The meat, which is white, flaky, and mild, is considered to be good eating, but contains many small bones. It is not of commercial importance (Scott and Crossman 1973).


Management: Regulations (pertaining to the Great Lakes)
The sale of dead chain pickerel is prohibited in Quebec under the Quebec Regulation Respecting Aquaculture and the Sale of Fish § RRQ, c C-61.1, r 7.

Note: Check federal, state/provincial, and local regulations for the most up-to-date information.

Control
Biological
There are no known biological control methods for this species.

Physical
The Maine Department of Inland Fisheries and Wildlife cites removal of fishing bag limits for Chain Pickerel as a management measure in certain lakes, noting that the rationale is biologically sound but negligibly effective because few anglers take advantage of the law and capture more than 10 pickerel per day. (Brokaw 2008 ).

Chemical
Of the four chemical piscicides registered for use in the United States, antimycin A  and rotenone are considered “general” piscicides, but no studies have been found of their effects on Esox niger (GLMRIS 2012).

Increasing CO2 concentrations, either by bubbling pressurized gas directly into water or by the addition of sodium bicarbonate (NaHCO3) has been used to sedate fishes with minimal residual toxicity, and is a potential method of harvesting fish for removal, though maintaining adequate CO2 concentrations may be difficult in large/natural water bodies (Clearwater et al. 2008). CO2 is approved only for use as an anesthetic for cold, cool, and warm water fishes the US, not for use as euthanasia, and exposure to NaHCO3 concentration of 142-642 mg/L for 5 min. is sufficient to anaesthetize most fish (Clearwater et al. 2008).

It should be noted that chemical treatment will often lead to non-target kills, and so all options for management of a species should be adequately studied before a decision is made to use piscicides or other chemicals. Potential effects on non-target plants and organisms, including macroinvertebrates and other fish, should always be deliberately evaluated and analyzed. The effects of combinations of management chemicals and other toxicants, whether intentional or unintentional, should be understood prior to chemical treatment. Boogaard et al. (2003) found that the lampricides 3-trifluoromethyl-4-nitrophenol (TFM) and 2’,5-dichloro-4’-nitrosalicylanilide (niclosamide) demonstrate additive toxicity when combined. In another study on cumulative toxicity, combinations of niclosamide and TFM with contaminants common in the Great Lakes (pesticides, heavy metals, industrial organics, phosphorus, and sediments) were found to be mostly additive in toxicity to rainbow trout, and one combination of TFM, Delnav, and malathion was synergistic, with toxicity magnified 7.9 times (Marking and Bills 1985). This highlights the need for managers to conduct on-site toxicity testing and to give serious consideration to determining the total toxic burden to which organisms may be exposed when using chemical treatments (Marking and Bills 1985). Other non-selective alterations of water quality, such as reducing dissolved oxygen levels or altering pH, could also have a deleterious impact on native fish, invertebrates, and other fauna or flora, and their potential harmful effects should therefore be evaluated thoroughly.

Note: Check state/provincial and local regulations for the most up-to-date information regarding permits for control methods. Follow all label instructions.
