“…The spread of the disease along with escaping crayfish, and possibly also with waste water from aquaria or ponds, is probable. Aphanomyces astaci DNA was also confirmed in other decapods from the outdoor locality, namely in native P. convexa and non-indigenous M. lanchesteri; these, and probably also shrimps and crabs too, may thus serve as vectors of this pathogen (Svoboda, Mrugała, et al, 2014;Svoboda, Strand, et al, 2014). Their sensitivity to crayfish plague is so far unknown, but the possibility that increasing levels of this pathogen in the environment may result in mortalities of crabs or shrimps cannot be excluded.…”

Numerous freshwater crayfish species are known to become successful invaders when introduced to new territories. One of the most invasive species in this group is the red swamp crayfish, Procambarus clarkii (Girard, 1852). In addition to other characteristics facilitating its invasiveness, it is also a vector of crayfish plague, a disease mostly lethal to crayfish of non‐North American origin. Procambarus clarkii, at present the most widespread crayfish species globally, is popular in many countries both for human consumption and as an ornamental animal. An established population of this species was documented for the first time within Indonesia, representing the first record for maritime Southeast Asia. The species is also common in the local ornamental pet trade. Infection by the crayfish plague pathogen Aphanomyces astaci Schikora was confirmed both in the outdoor population of P. clarkii and in one of the surveyed pet shops. Furthermore, A. astaci was detected in specimens of freshwater crab and shrimp species coexisting with P. clarkii. Local climatic conditions and the species temperature requirements suggest a high probability of the establishment of P. clarkii in Indonesia. Its further spread could irreversibly damage populations of many native endemic crustaceans in the country (as well as elsewhere in the region), and the thriving local aquacultures of the redclaw crayfish Cherax quadricarinatus (von Martens, 1868) may also be threatened. The total ban of P. clarkii and other crayfish species of North American origin in Indonesia is strongly recommended, especially considering that aquaculture and trade with Australasian species is a viable alternative option.

“…As the native river crab Potamon fluviatile Herbst, 1785, protected under the regional law 18/88, is present in the area (and was even found in the same trap with P. clarkii), the presence of alien crayfish carrying plague elicits great concern for the conservation of this species. Other crustaceans known to be susceptible to infection by A. astaci are the Chinese mitten crab (Eriocheir sinensis) (Benisch, 1940) [24], the crab Potamon potamios (Olivier, 1804) [25], and the Asian shrimp Macrobrachium dayanum (Henderson, 1893) and Neocaridina davidi (Bouvier, 1904) [26], thus, we cannot discard the hypothesis that P. fluviatile could be affected. The connectivity of the Natural Reserve has been increased by the ecosystem restoration project in Pantanello, which was planned to create an area of conservation interest for several species without considering its potential for favouring the dispersal of P. clarkii.…”

The Red Alien vs. the Blue Destructor: The Eradication of Cherax destructor by Procambarus clarkii in Latium (Central Italy)

et al. 2018

Cherax destructor is a crayfish endemic to south-eastern Australia and one of the last alien crayfish to be introduced in Italy. In the Laghi di Ninfa Natural Reserve (Latium region, Central Italy), the species was probably introduced in 1999, but only reported for the first time in 2008. Nearby this area, the most widespread alien crayfish is the red swamp crayfish Procambarus clarkii. In the Natural Reserve, between 2008 and 2013 and during spring and summer, crayfish sampling was carried out with baited traps to assess the distribution of C. destructor and its possible relationship with P. clarkii. Cherax destructor was first recorded in 2008; few P. clarkii were detected in the cultivation ponds where C. destructor was present in 2012 and 2013. Moreover, crayfish plague analyses evidenced a positive result in two out of the 12 sampled P. clarkii. Cherax destructor is now completely absent from the Natural Reserve, while P. clarkii has spread in the area and was probably responsible for this eradication since C. destructor is vulnerable to crayfish plague which was also detected in the area. An ecosystem restoration project in the area favoured the spread of. P. clarkii; the implications of this intervention are discussed.

The crayfish plague pathogen, Aphanomyces astaci Schikora, has become one of the most well-studied pathogens of invertebrates. Since its introduction to Europe in the mid-19th century, it has caused mass crayfish mortalities, resulting in drastic declines of local populations. In contrast, North American crayfish usually serve as latent carriers, although they may also be negatively affected by A. astaci infections under some circumstances. Recent research benefiting from molecular tools has improved our knowledge about various aspects of A. astaci biology. In this review, we summarize these advances, particularly with respect to the host range and transmission. We highlight several aspects that have recently received particular attention, in particular newly confirmed or suspected A. astaci hosts, latent A. astaci infections in populations of European crayfish, and the relationship between A. astaci genotype groups and host taxa.
