(Pacifastacus leniusculus).  Tuttavia allora non ci si rese conto che il signal crayfish era un portatore sano della malattia epidemica. 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).

Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. As well as being a voracious predator of plants, invertebrates, snails, small fish and fish eggs, the Signal crayfish carries the crayfish plague to which our native White-clawed crayfish is susceptible. It has been found in 28 territories in Europe since the 1960s, largely due to its high adaptability to a wide range of environments. Pacifastacus leniusculus. In: Huner JV, ed.

The biggest threat, however, to populations of white-clawed crayfish is the disease which is carried by signal crayfish known as the crayfish plague (Aphanomyces astaci), a water mould which can wipe The signal crayfish has a varied diet which includes fish, frogs, invertebrates, plants and sometimes other signal crayfish. Signal crayfish are sexually mature at the age of 2-3 years and can live up to 20 years. You can also find information and advice on introduced crayfish species and how you can help the White-clawed crayfish. Encased in a tough shell and armed with two large pincers it looks and indeed tastes rather like a freshwater Lobster or Langoustine and this is why I love to eat them.. (2014) have also demonstrated an increased density and resilience to control of invasive non-native mammalian carnivore populations such as the American mink, Neovison vison, in ecosystems with established invasive non-native crayfish populations, due the availability of a superabundant prey item. The signal crayfish can breed faster and outcompete white-clawed crayfish for resources whilst causing damage to the ecosystems which they colonise.

Nel 1960 la decimazione dei gamberi di fiume europei, provocata da un'epidemia causata dall'Oomycota, l' Aphanomyces astaci, ha determinato la sua importazione in Europa (Svezia e Finlandia ) come specie aliena, per riempire i vuoti lasciati da quelli nell'ecosistema. In fact, its use for restocking crayfish plague-devastated European waters is the primary reason for its current wide distribution in Europe. Signals are thought to be partly responsible for the decline in numbers of our indigenous species as they carry a disease commonly known as crayfish plague (Aphanomyces astaci) … The signal crayfish (Pacifastacus leniusculus) is a North American species of crayfish. by Holdich D M]. The signal crayﬁsh Pacifastacus leniusculus has been widely introduced in Europe, where it has had signiﬁcant adverse impacts on European species of crayﬁsh, by competition and by carrying crayﬁsh plague Aphanomyces astaci, which is lethal to the European species (Holdich, 1999). Invasive non-native species are one of the greatest threats to biodiversity in the UK. The crayfish escaped and now has well established populations all over the country, particularly in the south. California Fish and Game, 45:29-50, Skov, C., Aarestrup, K., Sivebæk, F., Pedersen, S., Vr?lstad, T., Berg, S., 2011.  Tutte le specie americane portano l'infezione ma essa è letale solo per quelle che sono particolarmente deboli; per le specie europee il contagio fu fatale.. Poiché esso, al contrario del gambero di fiume, sopporta anche temperature superiori, lo si può trovare anche in acque ferme, come i piccoli laghi.

Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. 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).

The target species Is the signal crayfish this is a non native species and has for different reasons been responsible for the decline of our native white clawed species the biggest of these being that the signal crayfish carries the crayfish plague which themselves are immune but our native species are not and the spores can last for 20-30 days in damp conditions without a host. Pl host specific, may be associated with crayfish mortalities, and signal crayfish in GB are likely to not currently be resistant .  È stata anche osservata sull'Isola di Man, ma non in Irlanda.
