“…It belongs to the Northern group of Cherax crayfish and inhabits streams, billabongs, and lakes in the northern part of the Northern Territory and far north Queensland in Australia and the southern part of New Guinea (Munasinghe et al, 2004;Bláha et al, 2016). This species has been successfully introduced to, and has established feral populations within, several tropical and subtropical countries, including Jamaica (Todd, 2002), Mexico (Bortolini et al, 2007;Vega-Villasante et al, 2015), Puerto Rico (Williams Jr et al, 2001), Singapore (Ahyong and Yeo, 2007;Belle and Yeo, 2010), and South Africa (De Moor, 2002). Only one population in the temperate zone has thus far been recorded, that being in Slovenia (Jaklič and Vrezec, 2011).…”

-Cherax quadricarinatus (von Martens) (Decapoda: Astacidea: Parastacidae) is commercially exploited and has been intentionally introduced to various tropical and subtropical countries. Once established in the wild, it frequently becomes invasive. In Indonesia, this crayfish is native only to the southern part of the Papua Province. Cherax quadricarinatus is produced in semi-intensive farms for food as well as for ornamental purposes on most of Indonesian territory. We present here the first record of this species from Java, where this crayfish has formed at least two established feral populations. In total, eight subadult and adult crayfish of both sexes were captured in two natural lakes in the city of Bogor, West Java Province. Based on climate match, we suggest that C. quadricarinatus has high potential to become established within most of Indonesian territory. As a rapidly growing species with broad tolerance to varying environmental conditions, its spread is expected and it should be viewed as a possible threat to native decapod crustaceans. Detailed monitoring is therefore needed.Keywords: crayfish / biological invasion / redclaw / climate match / Parastacidae Résumé -Cherax quadricarinatus (von Martens) a envahi le territoire indonésien à l'ouest de la ligne de Wallace : preuves à Java. Cherax quadricarinatus (von Martens) (Décapode : Astacidé : Parastacidé) est exploitée commercialement et a été introduite intentionnellement dans divers pays tropicaux et subtropicaux. Une fois établie dans la nature, elle devient souvent invasive. En Indonésie, cette écrevisse est originaire seulement de la partie sud de la province de Papouasie. Cherax quadricarinatus est produite dans des exploitations semi-intensives pour la consommation, ainsi que pour des fins ornementales sur la plupart des territoires indonésiens. Nous présentons ici le premier signalement de cette espèce à Java, où cette écrevisse a formé au moins deux populations sauvages établies. Au total, huit subadultes et adultes d'écrevisses des deux sexes ont été capturés dans deux lacs naturels dans la ville de Bogor, province de Java Ouest. Basés sur les conditions climatiques, nous suggérons que C. quadricarinatus a un fort potentiel pour s'établir dans la plupart des territoires indonésiens. Comme c'est une espèce à croissance rapide avec une large tolérance aux conditions environnementales variables, sa propagation est attendue et elle doit être considérée comme une menace possible pour les crustacés décapodes indigènes. Une surveillance étroite est donc nécessaire.Mots clés : écrevisse / invasion biologique / écrevisse bleue / climat / Parastacidés

“…Cherax quadricarinatus has fast growth, the ability to reproduce multiple times annually and to survive and reproduce under various biotic and abiotic conditions ranging from tropical to temperate (Jones 1995, Karplus et al 1998). These features make it not only an interesting species for aquaculture, but also a potential invader (Ahyong & Yeo 2007, Snovsky & Galil 2011, Jakli & Vrezec 2011. In fact, it has already established feral populations in South Africa, Mexico, Jamaica, Puerto Rico and Singapore (Williams et al 2001, Zimmerman 2003, Belle et al 2011.…”

Starvation resistance in juvenile freshwater crayfish

Strong starvation resistance has been observed in larval decapods developing in freshwater where food appearance may be unpredictable or poor. The point-of-no-return (PNR) has often been utilized to quantify the vulnerability of a given species or developmental stage to starvation. Most studies of nutritional effects on decapods focus on marine species, while there is less information on freshwater species. We evaluated the effects of starvation on survival, growth, and hepatopancreas structure of both early (first free-living stage, JIII) and late (1 g, J1g) juveniles of Cherax quadricarinatus. The experiments consisted of treatments with increasing numbers of days without food followed by continuous feeding until Day 60 (experiment with JIII) or 90 (experiment with J1g). Regardless of body size, the time from the beginning of the experiment to first ecdysis increased with the length of the starvation period. Growth was affected by starvation in JIII, but it recovered after feeding, while growth could not be fully compensated during subsequent feeding in J1g. PNR values (means ± SD) were 8.7 ± 0.3 and 51.0 ± 1.5 d, corresponding to 125 and 220% of total stage duration, respectively. In conclusion, juvenile C. quadricarinatus are highly resistant to starvation compared to early stages of other decapods. Freshwater environments with unstable conditions of food availability may have selected for strong starvation resistance, i.e. low nutritional vulnerability. This feature gives this species potential importance for aquaculture and as an invader.

Hence, the capability of a decapod to survive transitory lack of food and to subsequently recover from such periods depends on adaptive physiological and behavioral traits and, especially, on its capacity to store energy in the hepatopancreas.All these properties vary greatly among phylogenetic groups, developmental stages, reproductive periods, and adult habitats (Sulkin & McKeen 1999, Giménez & Anger 2005, Calado et al. 2010. A particularly strong starvation resistance has been observed in larval decapods developing in freshwater, at high latitudes, or in other highly variable habitats, where food availability may be unpredictable or on average poor (e.g. Anger et al. 2004, Paschke et al. 2004. Most studies of nutritional effects on decapods, however, focus on marine species (e.g. Liddy et al. 2003, Bas et al. 2008, Zhang et al. 2009, Gebauer et al. 2010, while less have been carried out on freshwater species (Jones & Obst 2000, Anger & Hayd 2009, Powell & Watts 2010.Using larvae of the spider crab Hyas araneus as a model, Anger & Dawi...

“…In the current study, the animals obtained from a pet shop were negative for infections, whilst the shipment from Singapore only contained temnocephalids and a single example of a ciliate infection of the gills. This species has become established in a number of water catchments in Singapore (Ahyong & Yeo 2007), and whilst not expressly commented on by those authors, it is interesting to speculate on its success in Singapore being due to an absence of pathogens.…”

A full histological survey of 782 non-indigenous crayfish established in riverine habitats or imported into mainland Britain through the aquarium trade was conducted. The selected populations were subjected to further bacteriological, molecular and ultrastructural studies to characterise disease conditions. Pacifastacus leniusculus, Orconectes virilis and Astacus leptodactylus were obtained from 16 rivers in mainland Britain. Additionally, Cambarellus patzcuarensis, Cherax quadricarinatus, Procambarus clarkii and P. fallax were obtained from 8 pet shops, whilst C. patzcuarensis, Cherax peknyi, C. quadricarinatus and P. clarkii were seized at a point of entry into Britain. Tests for infections were negative in the majority of P. leniusculus (66.4%); the rest were infected with at least one pathogen or commensal, including an intranuclear bacilliform virus and a novel Spiroplasma sp. of male Sertoli cells. Low level bacterial and ciliate infections and commensal mites and ostracods also occurred on or in established signal crayfish. The established population of O. virilis was found to be negative for any visible infections; one shipment of P. clarkii and one aquarium-held population of C. quadricarinatus were also found to contain no visible infections. One shipment of P. clarkii from Singapore was infected with white spot syndrome virus (WSSV). The bacterial species isolated from crayfish included Aero monas hydrophila, A. sobria, Citrobacter freundii, Grimontia hollisae, Hafnia alvei, Pasteurella multocida and Weeksella virosa. The results are discussed in relation to the enemy release hypothesis, and the risk associated with the transboundary trade in non-indigenous crayfish is considered as a potential source of disease to native crayfish species.
