It appears that crayfish may exhibit selectivity for particular plants but not among animal prey (Gherardi and Barbaresi 2007).
The animal constituents of the red swamp crayfish diet tend to be dominated by insects (particularly chironomids), other crayfish, mollusks (snails), and fish (Ilheu and Bernardo 1993, Pérez-Bote 2004). The influence of Procambarus clarkii (Cambaridae, Decapoda) on water quality and sediment characteristics in a Spanish floodplain wetland.
Setae on the anterior surface of the pleopod, closest to the terminal elements, have strong angular shoulders.
The right pleopod is wrapped around the side, such that it appears reduced or absent, and possesses a spur on the inner margin on its fifth joint (carpopodite) (WDFW 2003).
Nocturnal activity in the stationary phase does not appear to be driven by predatory avoidance (many of red swamp crayfish predators are also nocturnal) or prey capture (mostly herbivorous; Gherardi et al. Nonnative populations in the United States are likely to have resulted as a release from aquaculture or from the aquarium trade (Simon and Thoma 2006, Thoma and Jezerinac 2000; Kilian et al. This species’ striking red color has lead to commercial advertisement as freshwater “lobster” for aquariums and may have sped up the species’ advance on the west branch of the Grand Calumet River in Indiana and Illinois (Simon et al. The red swamp crayfish is readily available though the biological supply trade and may be released following classroom or laboratory use (Larson and Olden 2008; Kilian et al. It is also popular among anglers as bait for largemouth bass (WDFW 2003).
Intended disposal via the sanitary system (being flushed down toilets) is likely to be ineffective, as many has been seen in urban zones around waste water treatment areas, having apparently survived treatment (Indiana Biological Survey 2008). This species is commercially cultured in the southern U.
Recently hatched crayfish remain in the burrow with their mother as long as eight weeks and must molt twice before being self-sufficient (Hunter and Barr 1991).
Due to the cannibalistic nature of conspecifics in communal burrows, adult molting often occurs in the open, even in the presence of predatory fish (Hartman and O’Neill 1999).
2000) and collected from Sweetwater River in the San Diego National Wildlife Refuge (Cohen and Carlton 1995); established in Delaware (Gherardi and Daniels 2004); reported from Hawaii (Benson and Fuller 1999, Gutierrez 2003) and Idaho (Benson and Fuller 1999, Mueller 2001); collected from areas of the Dead River near Lake Michigan and in the North Branch of the Chicago River, Illinois; relatively rare but documented tributaries of Lake Michigan in the area of the Grand Calumet River in northern Indiana, with collections from Lake Michigan in 2000 (Simon 2001); established in Chesapeake Bay and all 14 watersheds of the Coastal Plain of Maryland (Kilian et al. 2000); reported from Nevada (Benson and Fuller 1999); found on Long Island, New York; established in the Neuse, Tar-Pamlico, Yadkin-Pee Dee, and Cape Fear river basins of North Carolina (Benson and Fuller 1999, Fullerton and Watson 2001); established and slowly spreading in the Sandusky Bay, Ohio area, with the first known collection dating back to 1967 and subsequent expansion to Bay, Rice, and Riley Township waterways connecting to Muddy Creek Bay and Margaretta and Townsend Twp tributaries of Lake Erie (R. comm.); established in Oregon, South Carolina, Utah, and Virginia (Benson and Fuller 1999, Mueller 2001); established or collected from several lakes in Washington (Mueller 2001, WDFW 2003); and established in a private subdivision pond in Germantown, Wisconsin from 2009-2016, reported as eradicated in 2016 (Behm 2009, Bunk and Van Egeren 2016); reported from the Missouri River in Nebraska, just below Gavins Point Dam in 2016 (S. also frequently colonizes rice fields, irrigation channels, and reservoirs (Correia and Ferreira 1995, Gherardi et al. It exhibits considerable ecological plasticity and is tolerant of a range of salinities up to 35ppt (Bissattini et al.
The Sandusky Bay, OH populations likely stem from an attempted introduction to see if they could get a harvestable population established for human consumption (R. S., particularly in Louisiana, where industry profits exceed 0 million annually and the fishery is an integral part of the state’s culture and economy (Mc Alain and Romaire 2011). has the potential for a wide array of environmental impacts, including food web alteration, bioaccumulation of toxic substances, community dominance, competition with native species for food or space, modification of physical-chemical habitat properties, consumption of native plants and algae, and predation on native species (Savini et al. Red swamp crayfish has the potential to successfully colonize northern and colder habitats since it has shown to have biological plasticity in its ability to adapt to atypical thermal habitats.
