  • White River Crayfish Procambarusprocambarus Acutus Aacutushemimysis Acutus Acutus Anomala
    White River Crayfish www.seagrant.psu.edu ProcambarusProcambarus acutus aacutusHemimysis acutus acutus anomala The white river crayfish, also called the white river crawfish and the eastern white river crayfish, is often confused with its southern counterpart, the southern white river crayfish (Procambarus zonangulus). The eastern white river crayfish occurs naturally in the United States and is cultured eastwards from Lousiana to the Atlantic coast northward to Maine, Photo courtesy of Tony Palacios, but has established select non-native populations in locations throughout the East Coast iNaturalist.org, EOL. and in California. Species Description Adult white river crayfish are usually a dark burgundy red but can range in color from pinkish tan to brownish olive with a black “V-shaped” stripe on the abdomen. The carapace is rough and granular and is separated in the middle by a narrow space called the areola. Juveniles are gray with dark spots scattered over the carapace. The claws are long and narrow, delicate in appearance, and have small dark tubercles. This species reaches about 6-13 cm (2.5-5 in) in length. The white river crayfish is nearly impossible to distinguish from the southern white river crayfish without looking at the reproductive structures of a breeding male. It is also confused with the red swamp crayfish (P. clarkii), which have an areola that is straight, or often invisible, and a black “V-shaped” stripe on the abdomen. The juveniles are also typically plain or striped on the carapace instead of spotted. White river crayfish can also be found in streams and ditches with a stronger flow than what is preferred by the red swamp crayfish.

Sometimes it’s the smallest travelers who end up on the biggest journeys. And in this story, that journey is nothing less than a circumnavigation powered by biology, and by business. We start with Procambarus clarkii – the red swamp crawfish. <crawfish bag cutting> Michael Robertson scissors off the top of a mesh bag stuffed with crawfish… <crawfish bag dump> …and pours them onto a sorting table. There are hundreds of them. Robertson: A nice sack here – all very lively crawfish. Ari: Robertson works here, at Big Fisherman Seafood – a well-known crawfish shop in New Orleans. He acts quickly to separate the live, crawling crawfish from the occasional dead ones. Then he boils them in a large pot, along with some garlic. Robertson fishes out a couple of the cooked ones. Robertson: You just peel ’em and eat ’em there. These are done, ready to come out. Ari: Rusty Gaude, with Louisiana Sea Grant, looks on. He’s been studying and selling crawfish – in one form or another – for the last 30 years. He says that Louisianans have their French ancestors to thank for crawfish cuisine. Gaude: In France, they had a long tradition of eating crawfish. And so when those French people came over here, they saw an animal – not quite the same, it’s actually a different genus. But it’s still a crawfish and they knew exactly what to do with it. And they said, “You’re gonna look good in a pot.” Ari: Over time, the Louisiana crawfish industry grew.

GELDER Department of Biology, University of Maine at Presque Isle, 181 Main Street, Presque Isle, Maine, USA. E-mail: [email protected] Abstract Over the last 130 years demand for crayfish has exceeded regional supplies around the world, so stocks, primarily from North America, have been imported to satisfy this need. These demands are human based and include gastronomy, sport fishing bait, food for rearing animals, educational aides, ornamentation in waterbodies, and more recently a significant increase in pet crayfish sales. The three most common commercial species from North America are Pacifastacus leniusculus, Procambarus clarkii and Orconectes limosus, although four other species are increasing in importance as they become more widely distributed. All of these crayfish in their endemic range have been reported to carry branchiobdellidan annelids. Therefore, when the crayfish are translocated, their ectosymbionts likely accompany them. Eighty-six potentially transportable branchiobdellidans are recognized in this paper, along with the distribution of six species known to have been translocated. Moreover, branchiobdellidans endemic to the translocation regions have adopted introduced crustacean hosts, which demonstrates that branchiobdellidan host species specificity is not as restrictive as many researchers believe. On the evidence to date, these translocated branchiobdellidans appear to have the same relationship and cause the same amount of damage, if any, as those on their endemic crayfish hosts.

  • Procambarus Clarkii Global Invasive
    FULL ACCOUNT FOR: Procambarus clarkii Procambarus clarkii System: Freshwater Kingdom Phylum Class Order Family Animalia Arthropoda Malacostraca Decapoda Cambaridae Common name red swamp crayfish (English), Louisiana crayfish (English) Synonym Similar species Procambarus zonangulus Summary Procambarus clarkii is a highly adaptable, tolerant, and fecund freshwater crayfish that may inhabit a wide range of aquatic environments. It is native to parts of Mexico and the United States and has established throughout the world as a result of commercial introductions for harvest as a food source. Invasive populations have been reported from Europe, Asia, Africa, North America, and South America. Impacts include aggressive competition with native crayfish, introduction of the crayfish plague, reduction of macrophyte assemblages, alteration of water quality, predation on and competition with a variety of aquatic species, and negative impacts on agricultural and fishing industries. Management strategies for P. clarkii include trapping and removing populations, creating barriers to prevent its spread, prohibiting the transport of live crayfish, and improving public education about it risks to the environment. Encouraging farming of native species as well as research on economically productive harvesting of native crayfish has the potential to reduce further introductions. view this species on IUCN Red List Species Description Typically dark red, Procambarus clarkii is capable of reaching sizes in excess of 50g in 3-5 months (NatureServe, 2003; Henttonen and Huner, 1999). Adults reach about 5.5 to 12cms (2.2 to 4.7 inches) in length. Its rostrum is cuminate with cervical spines present, and its areola is linear to obliterate.
