“…For instance, it is has been predicted that redclaw can develop invasive behaviour (e.g. in New Guinea, see Patoka et al 2018), suggesting potentially impact native fauna through competition for shelter (Chivambo et al 2020), predation on, for example, native macroinvertebrate communities (de Moor 2002;Marufu et al 2018a) and eggs of nesting fish (Marufu et al 2018a). In association with the suggested predation impact of redclaw, aggressive behaviour of other crayfish species has been cited, for example red swamp crayfish towards giant river prawn Macrobrachium rosenbergii (De Man, 1879) (Chaichana & Wanjit 2018), or other Cherax species towards each other (Austin & Ryan 2002) as well as towards aquatic vertebrates (Bradsell et al 2002; Table 2).…”

“…Although redclaw is generally considered a non-burrowing species(de Moor 2002;Wingfield 2002), preliminary observations in Jamaica and La R eunion have revealed burrow construction along river banks, which could potentially weaken their stability(Todd & D'Andrea 2003;Robinet 2010; Todd 2017), indicating that irrigation systems and associated regulating ecosystem services can also potentially be disrupted by the species. impacts, such as effects on fish and other fauna that rely on macrophytes and suitable benthic habitat for food, shelter, and reproduction(Weyl et al 2017;Marufu et al 2018a); and / or changes in sediment / nutrient dynamics or even lake states(Twardochleb et al 2013;Mathers et al 2019; Emery-Butcher et al 2020).…”

The redclaw crayfish (Cherax quadricarinatus; hereafter redclaw), native to northern Australia and southern New Guinea, is among the largest freshwater decapods. It matures early and is considered highly prolific as females may lay over one thousand eggs in a single clutch. Despite generally preferring slow-moving streams in its native range, it has a wide environmental tolerance, making it capable of establishing populations when introduced to a wide range of other conditions and habitats. These biological and ecological features render it a highly suitable and popular species for aquaculture worldwide, being the second most important crayfish species economically (after the red swamp crayfish Procambarus clarkii). Adding to that, its unique coloration fuels demand and value among aquarium enthusiasts, making it attractive for the aquarium pet trade. Today, redclaw is widely translocated (67 countries/territories) and various established wild populations (22 countries) have been reported on every continent except Antarctica. Information on its potential or observed impacts, however, is sparse and often anecdotal. To address this gap, this comprehensive review compiles all available information on this species, covering its taxonomy and description, biology and ecology, native and non-native ranges accompanied with documented introduction pathways. Built upon these, we conducted biological and socio-economic classification and species distribution modelling. We reveal a lack of thorough impact assessments for this species despite sufficient indications of major observable impacts at local scales. We call attention to the importance of managing the use of this prominent introduced species in aquaculture and aquarium pet trade.

“…Baited traps are the most commonly applied method (Larson and Olden, 2016). While a variety of traps have been used in crayfish surveys in Africa (see Madzivanzira et al, 2020), two designs -opera traps (Marufu et al, 2014(Marufu et al, , 2018 and Promar collapsible traps (Nunes et al, 2017) -are the most commonly applied methods for sampling C. quadricarinatus in southern Africa. Bait also differs between surveys, with choices including cooked maize meal (e.g.…”

Freshwater crayfish are damaging invaders across southern Africa; however, monitoring techniques and efforts are disparate across the region as different sampling methods have been used. To develop a standard method for assessing redclaw crayfish Cherax quadricarinatus abundance, a survey was conducted to assess for differences in detection and catch per unit effort (CPUE) in Lake Kariba. Two sampling approaches were compared: opera traps baited with cooked maize meal historically used in crayfish surveys in Zimbabwe, and Promar collapsible traps baited with dry dog food, which have been used for assessments in South Africa and Swaziland. Baits were compared in the Barotse Floodplain in Zambia using the Promar trap. Detection probability (Pcapture) and CPUE were significantly lower for opera traps baited with cooked maize meal (Pcapture = 0.41; CPUE = 1.19 ± 0.24 ind.·trap-1·night-1) compared to the Promar traps baited with dry dog food (Pcapture = 0.67; CPUE = 4.53 ± 0.82 ind·trap-1·night-1). The Pcapture and CPUE for Promar traps baited with dog food (Pcapture = 0.89; CPUE = 4.29 ± 0.83 ind·trap-1·night-1) was significantly higher than for maize meal baited traps (Pcapture = 0.29; CPUE = 0.25 ± 0.17 ind·trap-1·night-1). Sex ratio and carapace length of crayfish sampled did not differ between sampling methods. Due to higher CPUE, the authors consider the Promar collapsible trap baited with dog food approach as the better method for determining crayfish population abundance and suggest that comparisons of abundance take this into consideration by applying conversion factors if different methods are applied.
