Marmorkrebs: Natural crayfish clone as emerging model for various biological disciplines

Marmorkrebs (Procambarus fallaxf.virginalis) are the most popular crayfish in the North American pet trade

“…Marmorkrebs is an emerging model organism (Vogt, 2008(Vogt, , 2011, but its interactions with other species in natural habitats, particularly with other crayfish, are still mostly unknown (but see Chucholl and Pfeiffer, 2010;Jimenez and Faulkes, 2011). Of the top four crayfish species in the North American pet trade, P. clarkii is the only crayfish species whose biology has been extensively studied.…”

Appendage regeneration after autotomy is mediated by Baboon in the crayfish Procambarus fallax f. virginalis Martin, Dorn, Kawai, Heiden and Scholtz, 2010 (Decapoda: Astacoidea: Cambaridae)

“…Procambarus fallax f. virginalis is known to reproduce by apomictic parthenogenesis, with all offsprings representing clones (Vogt, 2011). Accordingly, all experimental animals used in this study were clones of a single female that was purchased from Tropiland (Tokyo, Japan).…”

Expansion of the marbled crayfish in Slovakia: beginning of an invasion in the Danube catchment?

“…The amount of juveniles increases with each cycle in relation to size increase of the maternal individuals (Vogt, 2011), and may reach very high values for large females. Under laboratory conditions, Vogt (2011) reported the maximum number of 427 juveniles in one clutch. Some field-collected individuals were nevertheless even more fecund: one female from Madagascar studied by Jones et al (2009) carried approximately 530 eggs (see Fig.…”

“…It is estimated that under the laboratory conditions, the marbled crayfish can complete up to seven reproduction cycles during its lifespan of 2 to 3 years, and the generation time is about 6-7 months (Vogt, 2010). The amount of juveniles increases with each cycle in relation to size increase of the maternal individuals (Vogt, 2011), and may reach very high values for large females. Under laboratory conditions, Vogt (2011) reported the maximum number of 427 juveniles in one clutch.…”
