PROCAMBRUS CLARKII

Definition

Crayfish, native of southern North America where it is cultured extensively in ricefields. The species has been transferred to Europe and China where it either thrives in natural water bodies, partly replacing native species, or is extensively cultured (in particular in China). It dwells mainly in lotic waters, but is also found in lentic, vegetated waters. It is resistant to oxygen content as low as 3mn dm 3 and tolerant of a wide pH range. Once introduced into a water body, it out-competes native crayfish species, thereby changing ecosystem functioning and structure. The largest producers of the red swamp crayfish are the USA and China (Spain in Europe). The meat is low-priced as it is of lower quality than that of the noble crayfish.
