The state of crayfish in the Pacific Northwest., 36 60-73. P. leniusculus can be found in a variety of habitats, from small streams to large rivers and natural lakes. Biology, Management and Exploitation. In two similar rivers in Yorkshire (UK), high P. leniusculus densities correlated with low salmonid fish densities (brown trout, Salmo trutta), whilst high native white-clawed crayfish, Austropotamobius pallipes, densities correlated with high fish densities, suggesting a population level impact of P. leniusculus on fish communities (Peay et al., 2009). P. leniusculus has also been introduced outside of Europe, to Japan (Hiruta, 1996). Accessed 23 September 2004, Bernardo J M, Costa A M, Bruxelas S, Teixeira A, 2011. More information about modern web browsers can be found at http://browsehappy.com/. Freshwater crayfish. It was introduced to Europe in the 1960s to supplement the North European Astacus astacus fisheries, which were being damaged by crayfish plague, but the imports turned out to be a carrier of that disease.

The signal crayfish can breed faster and outcompete white-clawed crayfish for resources whilst causing damage to the ecosystems which they colonise. P. leniusculus is now widely cultivated in Europe and has provided a culinary substitute following the decline of the native European species, Astacus astacus, from crayfish plague.

Poiché esso, al contrario del gambero di fiume, sopporta anche temperature superiori, lo si può trovare anche in acque ferme, come i piccoli laghi. Native crayfish species are frequently replaced due to having lower fecundities (Eng and Daniels, 1982), an inferior ability to compete for shelter leading to an increased susceptibility to predation (Dunn et al., 2009), vulnerability to reproductive interference leading to diminished recruitment (Westman et al., 2002) or due to being directly predated upon (Nataka and Goshima, 2006).
