The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected.

Cherax quadricarinatus (von Martens, 1868)

Common name: Australian redclaw crayfish

Synonyms and Other Names: Queensland Redclaw Crayfish, Tropical Blue Crayfish, Freshwater Blueclaw Crayfish, North Queensland Yabby, Blue Lobster

Taxonomy: available through www.itis.govITIS logo

Identification: Cherax quadricarinatus is a large bodied crayfish with a blue-green to green color with red and maroon highlights. Adult males have a soft, fleshy, bright red patch on the outer margin of the major chelae. This species also has four long and distinct carinae (ridges) on the dorsal surface of the cephalon (Coughran and Leckie 2007).

Size: Cherax quadricarinatus may reach a total length of about 250 mm and weigh up to 600 grams (Ahyong and Yeo 2007)

Native Range: Cherax quadricarinatus is native to Australia, and can be found in freshwater creeks and water bodies in tropical Queensland, the Northern Territory and southeastern Papua New Guinea (Coughran and Leckie 2007).

Nonindigenous Occurrences: Cherax quadricarinatus is established in Puerto Rico. Multiple farms had stocked the species in earthen ponds in northeastern Puerto Rico without local Natural Resource Management’s knowledge. Adults of the crayfish were discovered to have escaped after Hurricane George hit Puerto Rico on 09/22/1998. The species is now established in the Loiza River and Carraizo Reservoir. C. quadricarinatus has maintained its numbers and is now expanding its range in Puerto Rico (Williams et al. 2001).

Additional feral populations have been established in South Africa, Mexico, Jamaica, and Singapore (Ahyong and Yeo 2007)

Ecology: Cherax quadricarinatus is tolerant of a wide variety of habitats can be found in tropical and subtropical climates coastal streams and freshwater environments, with a preference for the slower moving upper reaches of rivers as well as lakes and lagoons (Wingfield 2002). Cherax quadricarinatus is a non-burrowing species that is tolerant of high temperatures and relatively low dissolved oxygen concentrations (Masser and Rouse 1997).

Like most North American crayfish species, Cherax quadricarinatus is an omnivorous detritivore, feeding on plant and animal decay. However, unlike native crayfish, the species does not rely on enviromental cues for seasonal breeding, such as temperature changes, but instead, can breed all year, with multiple broods being produced in water temperatures above 75F. Cherax quadricarinatus reaches sexual maturity before one year of age, with females producing up to 1000 eggs and 3-5 broods during a breeding season (Masser and Rouse 1997).

Cherax quadricarinatus exihibits the traits of both r- and K- selected species, with its life history including high numbers of offspring with low mortality rates and large body sizes, likely promoting the species' successful colonization in many areas outside of its native range (Beatty 2005).

Means of Introduction: This species has high growth rates and tolerance to wide variations in water quality making it suitable for aquaculture  (Anson and Rouse 1994; Coughran and Leckie 2007). In Puerto Rico, the species was introduced by aquaculture escapes (Williams et al., 2001). The hardiness and colorfulness of C. quadricarinatus has also make it popular in the aquarium trade, making aquarium dumps a possible means of introduction (Ahyong and Yeo 2007; Coughran and Leckie 2007).

Status: Established in Puerto Rico (Williams et al. 2001).

Cherax quadricarinatus is aggressive and possibly constitutes a threat to native Puerto Rico freshwater shrimps (Williams et al. 2001). This species has the potentail to impact native fauna through direct competition, predation or habitat modification (Ahyong and Yeo 2007). C. quadricarinatus has also been reported to be a carrier of a number of pathogens, including viruses, bacteria, fungi, protozoan and metazoan parasites that could spread to native crayfishes and shrimps (Ahyong and Yeo 2007; Austin et al. 2009).

Remarks: Cherax quadricarinatus is in the aquaculture industry in countries such as Belize, China, Indonesia, Israel, Morocco, Panama, Spain, and the United States (Rubino et al. 1990; FAO, 2011-2013).
