Reproductive frequency (?) | Iteroparous References (not structured): Kouba, A., B. Lipták, J. Kubec, M. Bláha, L. Veselý, P.J. Haubrock, F.J. Oficialdegui, H. Niksirat, J. Patoka, and M. Buřič. 2021. Survival, Growth, and Reproduction: Comparison of Marbled Crayfish with Four Prominent Crayfish Invaders. Biology 10(5), 422. Comments: Females are capable of reproducing five times a year in suitable conditions and reach sexual maturity at less than one year old. Clutch size is typically 300 to 500 eggs but instances of large females carrying 1400 eggs have been reported. |
Reproductive type (?) | Sexual References: Sandeman, R., Sandeman, D. 1991. Stages in the development of the embryo of the fresh-water crayfish Cherax destructor. Roux's archives of developmental biology, 200, pp. 27-37. |
Developmental trait (?) | Brooding Parental care References: Withnall, F. 2000. Biology of Yabbies (Cherax destructor). State of Victoria, Department of Natural Resources and the Environment. Comments: Females carrying eggs provide parental care by ensuring a well oxygenated environment and keeping eggs clean and free of foreign particles. |

Shelly, 2024, Cherax destructor (Clark, 1936): U.S. Geological Survey, Nonindigenous Aquatic Species Database, Gainesville, FL, and NOAA Great Lakes Aquatic Nonindigenous Species Information System, Ann Arbor, MI, https://nas.er.usgs.gov/queries/greatlakes/FactSheet.aspx?Species_ID=3648&Potential=Y&Type=2, Revision Date: 2/1/2024, Access Date: 7/9/2024 Comments: C. destructor is an omnivorous species that feeds on plants, detritus, and some arthropods. Their diet also switches according to climate. During summer seasons, they tend to eat fish, and in the winter, they eat plants and detritus. C. destructor may have cannibalistic tendencies in areas where there is an overabundance of the species and low levels of natural food sources |
Mobility / Life stage (?) |
References (not structured): Withnall, F. 2000. Biology of Yabbies (Cherax destructor). State of Victoria, Department of Natural Resources and the Environment. Comments: Cherax destructor exhibits a burrowing behavior that can alter the habitat by destabilizing the banks of lakes, rivers, and streams, construct burrows that are connected by tunnels. |
Salinity tolerance range (?) | Exact range: 0 - 16 References: Withnall, F. 2000. Biology of Yabbies (Cherax destructor). State of Victoria, Department of Natural Resources and the Environment. NSW Department of Industry. 2017. Yabby- aquaculture prospects. http://www.dpi.nsw.gov.au/fishing/aquaculture/publications/species-freshwater/freshwater-yabby. Created on 04/27/2016. Accessed on 09/07/2024. U.S. Fish and Wildlife Service (n.d.). Ecological Risk Screening Summary: Yabby (Cherax destructor). Available at: https://www.fws.gov/sites/default/files/documents/Ecological-Risk-Screening-Summary-Yabby_0.pdf [Accessed 9 July 2024]. Comments: C. destructor is a freshwater crayfish, inhabits a variety of habitats, such as springs, lakes, alpine streams, subtropical creeks, swamps, dams, and irrigation canals. High salinity levels are tolerated by yabby, but only for a period of time. They can tolerate seawater for up to 48 hours, but after this stress on their systems, they stop growing. Activity and optimal growth are achevied when salinity levels are above than 8 ppt. C. destructor will die at a salinity of 16 ppt or above. |
Habitat modifying ability potential (?) | Allogenic ecosystem engineers Comments: Crayfish are environmental engineers – they dig burrows, chew on submerged logs and rearrange aquatic vegetation, all to the benefit of other freshwater species. |
Toxicity / Life stage (?) | Not relevant |
Bioaccumulation association (?) | Anthropogenic chemical compounds References: Bruno, G., Volpe, M. G., De Luise, G., Paolucci, M. 2006. Detection of heavy metals in farmed Cherax destructor. Bulletin Français de la Pêche et de la Pisciculture, (380-381), pp. 1341-1349. |
Known human health impact? | Known References: Khan, S., Nugegoda, D. 2003. Australian freshwater crayfish Cherax destructor accumulates and depurates nickel. Bulletin of Environmental Contamination & Toxicology, 70(2), pp. 308–314. Comments: C. destructor consumption by humans and aquatic animals, metal accumulation by this specie, can affect the health of humans or animals |
Known economic impact? | Known References: Jones, P.L., Chavez, J.R. , Mitchell, B.D. 2002. Production of Australian freshwater crayfish in earthen-based systems using pelleted diets and forage crops as food. Aquaculture International, 10, pp. 157–175. Comments: Cherax destructor has commercial value but its economic contribution is small. It has become a target species for aquaculture in several countries and is employed recreationally as bait but adds little value to local communities or tourism. |
Known measurable environmental impact? | Known References: NSW Department of Industry. 2017. Yabby- aquaculture prospects. http://www.dpi.nsw.gov.au/fishing/aquaculture/publications/species-freshwater/freshwater-yabby. Created on 04/27/2016. Accessed on 09/07/2024. Comments: Aggressive behaviour may push out native species for food and habitat, reducing biodiversity and changing species composition of ecosystems. |
