Summary of InvasivenessTop of page
The black crappie is a freshwater fish, which has been widely introduced as a game species throughout North America. It is omnivorous, and in the absence of predators may overpopulate areas, altering fish communities through competition and predation. It has been reported to cause salmon declines in rivers of northwest USA and also reduce populations of endemic and native prey species, including invertebrates and fish. In the USA, it has also been reported as affecting the endangered Warner sucker, Catostomus warnerensis, and the critically endangered Shasta crayfish, Pacifastacus fortis.

Notes on Taxonomy and NomenclatureTop of page
Black crappie Pomoxis nigromaculatus was first described by Lesueur in 1829 and had several synonyms in the nineteenth and twentieth century namely; Cantharus nigromaculatus, Pomoxis barberi, Centrarchus hexacanthus, Hyperistius carolinensis, Labrus sparoides.
DescriptionTop of page
Black crappie have a laterally compressed and deep body, silvery green in colour with yellow-greenish sides and irregular black splotches. The tail and ventral fins are covered by flecks, though juveniles tend to have less pigment than adults. During the breeding season, males have a darker head and breast. Individuals generally have 7 but can occasionally have 8 dorsal spines, with 5-8 anal spines and 6/7 branchiostegals. They have ctenoid scales, an S-shaped snout and symmetric anal and dorsal fins (Trautman, 1981; Becker, 1983; Sigler et al., 1987; Smith, 1979; Jenkins et al., 1994; Mettee et al., 1996).
DistributionTop of page
The species was originally found in most of the eastern half of the USA but it has been widely translocated across the country into many US states, including the north-eastern seaboard and in the west (Page and Burr, 1991).
Non-native distribution of the species includes Panama, Japan (not established), Morocco (not established), Mexico, Canada and China (Froese and Pauly, 2016).

History of Introduction and SpreadTop of page
Black crappie is a popular sport fish and its distribution range has been greatly expanded through intentional stockings. It is now found in almost all suitable freshwater ecosystems in the USA (Page and Burr, 1991) and has been introduced from the USA to China, Mexico, Japan and Panama for aquaculture and to Morocco in 1961 as an ornamental fish (Welcomme, 1988).

Risk of IntroductionTop of page
Commonly found in freshwater systems as an intentionally introduced fish species, black crappie may overpopulate ecosystems, altering fish communities through competition and predation. There is a high risk of its introduction to new areas for fisheries and aquaculture (Becker, 1983; Batzer et al., 2000; Sanderson et al., 2009; US Fish and Wildlife Service, 2009; 2010; Hughes and Herlihy, 2012).
HabitatTop of page
Black crappie occur in shallow parts of large lakes, ponds, reservoirs and oxbow lakes and slower sections of large streams and rivers (Ross, 2001). Black crappie are found from turbid reservoirs and rivers, to eutrophic and highly fertile lakes, to dark water mesotrophic lakes, to clear lakes. In their natural range, they prefer densely vegetated, warm, sandy to muddy bottoms, moderately acidic, and non-turbid waters of lakes and rivers (i.e., <50 JTU) (Sigler and Sigler, 1987). They are usually found in the middle to upper sections of the water column in the summer (Ross, 2001), but in north temperate lakes that freeze during winter, black crappie are often found near the bottom in the deepest parts of the lake. They are found in open water during the day but the shore at night when they are more active (Keast and Fox, 1992). They favour pH values from 6.0 to 7.5 and oxygen of more than 5 mg/l (Ross, 2001). The preferred temperature range is 14-26°C, and the preferred spawning temperature is about 18-20°C.

Biology and EcologyTop of page
Black crappie have a diploid (2n) chromosome number of 48 and haploid/gametic (n) of 24 (Klinkhardt et al., 1995). It is known that they naturally hybridize with white crappie and artificially crossed with other genera (Schwartz, 1972; Travnichek et al., 1996).
Although it greatly varies among populations based on where they live, black crappie usually spawn between April and June, in water temperatures of 14-20°C. Individuals reach sexual maturity at two years of age. This species aggregates in shallow waters for feeding before spawning and then males prepare nests to attract females. Female black crappie have a very high egg production potential, usually 10,000-200,000 eggs depending on the size of the female. Males guard the nest until the juveniles can swim and feed freely (Becker, 1983; Robison et al., 1988; Jenkins et al., 1994; Mettee et al., 1996).
Physiology and Phenology
Black crappie are active in winter and during the day (Becker, 1983).
The longevity of black crappie is 15 years (Quinn, 2001).
Winter sees higher activity patterns (Becker, 1983).
Black crappie mainly feed early morning. Young individuals feed on planktonic crustaceans, dipterous larvae and zooplankton such as Cyclops spp., Cladocera, and Daphnia spp. Adults on the other hand feed on insects, minnows, and fingerlings of other species (Scott and Crossman, 1973). Black crappie are known to utilize all kinds of foods in the environment at all times of the year but the peak times for feeding are midnight, dawn, noon and dusk (Becker, 1983).
The species is highly tolerant of environmental factors such as temperature (up to 31°C) (Froese and Pauly, 2016), pH (6.0 to 7.5) and oxygen down to 5 mg/l. However, it prefers cool and moderately turbid <50 JTU) or stagnant waters <10 m/s) between 14 and 20°C (Ross, 2011).

Notes on Natural EnemiesTop of page
Large piscivorous fish, such as yellow perch (Perca flavescens), largemouth bass (Micropterus salmoides) and rock bass (Ambloplites rupestris) are potential predators of black crappie. Predatory aquatic insects and zooplankton (Diacyclops thomasi and Mesocyclops edax) may also be potential predators (Martinez, 1991).
Black crappie has been reported as infected with Gyrodactylus goerani and Gyrodactylus lineadactylus (Harris et al., 2004). The monogenes Haplocleidus dispar and Cleidodiscus vancleavei have been reported as parasites of the black crappie. Several protozoans, trematodes, cestodes, nematodes, acanthocephalans and leeches have also been recognised (Hoffman, 1967).
Means of Movement and DispersalTop of page
The main pathway is deliberate introductions for recreational fishing (Page and Burr, 1991). This fish species has been introduced to countries outside of its native range for fisheries enhancement, aquaculture and ornamental purposes (Welcomme, 1988).

Impact SummaryTop of page
Economic ImpactTop of page
Black crappie is an important fish for sportive fisheries, stocking and aquaculture (Becker, 1983). Due to its popularity as a game fish it may increase tourism and have positive local impacts (Sigler et al., 1987).
Environmental ImpactTop of page
Impact on Biodiversity
Black crappie is an omnivorous species, and in the absence of predators may overpopulate areas, altering fish communities through competition and predation. They have been reported to cause salmon declines in rivers of northwest USA (Sanderson et al., 2009) and reduce endemic and native prey species including invertebrates (critically endangered Shasta crayfish, Pacifastacus fortis and midge larvae) and fish (endangered Warner sucker, Catostomus warnerensis) and juveniles of their predators such as northern pike (Esoxlucius), walleye (Sander vitreus) and muskellunge (Esox masquinongy) (Becker, 1983; Batzer et al., 2000; US Fish and Wildlife Service, 2009; 2010; Hughes and Herlihy, 2012).

Social ImpactTop of page
This species is important for recreational fishing and may have positive impacts on tourism (Sigler et al., 1987).
Risk and Impact FactorsTop of page Invasiveness
- Has a broad native range
- Abundant in its native range
- Highly adaptable to different environments
- Is a habitat generalist
- Capable of securing and ingesting a wide range of food
- Benefits from human association (i.e. it is a human commensal)
- Has high reproductive potential
- Modification of natural benthic communities
- Reduced native biodiversity
- Threat to/ loss of endangered species
- Threat to/ loss of native species
- Highly likely to be transported internationally deliberately
UsesTop of page
Black crappie is an economically important game fish. It is a popular fish for anglers because of its white and flaky flesh. It can also be easily caught using a variety of methods and can be caught all year round, even in harsh winter conditions (i.e. ice covered lakes) (Becker, 1983; Sigler et al., 1987).
It is an important fish species for recreational fishery (Sigler et al., 1987). Its positive impacts on tourism may create a demand not only for food, accommodation and transportation, but also for related recreational activities such as camping, boating, etc. All of these activities may generate or improve economic incomes.
Uses ListTop of page
- Pet/aquarium trade
- Sociocultural value
- Sport (hunting, shooting, fishing, racing)
Similarities to Other Species/ConditionsTop of page
The black crappie is very similar in physical appearance to the white crappie (Pomoxis annularis) but the black crappie has a deeper body and a longer dorsal fin base, is silvery-green in colour and has 7/8 spines on its dorsal fin (white crappies have five or six dorsal spines) (Ross, 2001).
The black crappie can be easily distinguished from other sunfish by having less than 10 dorsal spines.
Prevention and ControlTop of page
Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Pesticides should always be used in a lawful manner, consistent with the product's label.
Due to its recreational value there is a lack of awareness of its impacts.
Little is known with regards to the potential control of this species using chemicals, physical or cultural control methods.
There is no evidence of biological control for this species but natural enemies could be used (e.g. yellow perch (Perca flavescens), largemouth bass (Micropterus salmoides), rock bass (Ambloplites rupestris) and zooplankton; Diacyclops thomasi and Mesocyclops edax) (Martinez, 1991).
Monitoring and Surveillance (Incl. Remote Sensing)
Both telemetry and radio telemetry could be used.
Gaps in Knowledge/Research NeedsTop of page
There is little awareness of the invasiveness of black crappie and the extent of its impact on other native species, the ecosystem structure and services. Following documented evidence of its impacts, appropriate prevention and control measures should then be planned and implemented.
