White River Crayfish (Crayfishes and Shrimp of the Green River, KY)

White River Crayfish

Procambarus acutus

Diagnostic description ²

Male with hooks on ischia of 3rd & 4th pereiopods; first pleopod with tuft of subapical setae borne on distinct knob situated laterodistally near base of cephalic process.

Distribution ³

Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) Complete and accurate range is ambivalent because of taxonomic confusions and widespread introductions; it probably was originally from the Tombigbee basin, northeast along coastal plain and piedmont to New England but absent from north of Boston (1 record) and central and western Connecticut (Smith, 1982; 2000). According to Hubbs (1989), it ranges from Maine to the Florida panhandle west to Texas and north to Minnesota. It has been introduced by aquaculturists in many places. The subspecies cuevachicae known from San Luis Potosi, Mexico (Moles and Tistler, 1995).

Habitat and ecology ⁴

Habitat and Ecology

This speciesis found in permanent sluggish, to moderately flowing streams and most permanent lentic (lakes, swamps, ponds) water bodies (Thoma and Jezerinac 2000). In West Virginia, this species has been found in ephemeral wetland habitats (Loughman 2007). It is considered to be a habitat generalist (US Forest Service 2008).

Justification

Procambarus acutus hasbeen assessed as Least Concern. This species natural range that encompasses 29 US States, and inhabits a range of habitat types. Further research is required to clarify the taxonomy of this species, as well as to determine its abundance, and whether it is being impacted upon by any major threat processes.

Nature serve conservation status ⁶

Rounded Global Status Rank: G5 - Secure

Reasons: This species natural range encompasses more than half of the US States and is a habitat generalist, being able to utilize both stream and pond habitats. It is not found locally in abundance, but is clearly widely distributed and tolerant of a great range of habitats. The species is part of a species complex with several widespread clades within it. For a robust assessment of this species, a taxonomic study of the species boundaries in the complex is in need.

Intrinsic Vulnerability: Not intrinsically vulnerable

Comments: It is a habitat generalist, being able to utilize both stream and pond habitats

Range description ⁷

This speciesis known from the coastal plain and piedmont from Maine to Georgia, and from the Florida panhandle to Texas, and Minnesota to Ohio (Ghedotti 1998, Loughman 2007). Furthermore, this species has been introduced to many areas of the US, including California, Maine and Kentucky (Loughman 2007).
