Etiological characteristics of “tail blister disease” of Australian redclaw crayfish (Cherax quadricarinatus)

Tail Fan Necrosis syndrome in decapod crustaceans: A review

“…In China, Zhang et al. (2021) examined blister fluid and haemolymph from healthy and diseased farmed redclaw crayfish ( Cherax quadricarinatus (Von Martens)). Symptoms observed were blisters on the tail, associated with high mortality rates in the lobster population (80%).…”

“…Decapods can also rapidly clear injected viruses and bacteria from their haemolymph within as little as 5 to 10 min (Review: Martin et al., 1993). The hypothesis that bacteraemia in lobsters indicates a compromised immune system (Fotedar et al., 2006) has not been disproven by those studies that seek to explain observed bacteraemia in their animals as ‘normal’, despite significant stress events occurring prior to sampling (Bartlett et al., 2008; Zhang et al., 2021). Such studies have flawed methodology in that the experimental design does not account for the possibility that the lobsters are highly stressed through capture and holding, or even that the lobster might already be subclinically infected (Bang, 1970; Fotedar et al., 2001; Fotedar & Evans, 2011; Paterson et al., 1997; Paterson & Spanoghe, 1997; Tsvetnenko, 2001).…”

“…in Queensland (Herbert, 1987). The syndrome occurs in Western Australian yabbys ( Cherax destructor albidus C lark) and marron ( Cherax cainii Austin) (Mosig et al., 2001) as well as Cherax quadricarinatus (Von Martens) an Australian species now farmed in China (Zhang et al., 2021). It has also been reported to be present in wild capture lobster fisheries around Australia but the severity of cases was reported to be low (Geddes et al., 2004).…”

Cloning and expression of three small heat shock proteins in Cherax quadricarinatus under Vibrio alginolyticus or Aeromonas hydrophila stress

“…It is a large‐sized and highly fecund species of freshwater crayfish, and has become one of the world's most intensely studied crustaceans (Yang et al, 2020). C. quadricarinatus is an economically valued freshwater crayfish (Shun et al, 2020), but it is susceptible to a number of pathogens, such as Aphanomyces astaci (Hsieh et al, 2016), Aeromonas veronii, Aeromonas hydrophila (Zhang et al, 2021), white spot syndrome virus (Meng et al, 2020), iridovirus (Li et al, 2017) and vibriosis.…”

“…Aeromonas hydrophila is widely distributed in nature (Anjur et al, 2021; Nayak, 2020) and is a typical pathogenic bacterium of human‐zoon‐fish comorbidity (Awan et al, 2018). In 2019, Aeromonas hydrophila and Aeromonas veronii induced acute disease outbreak in C. quadricarinatus occurred on a farm in China, with a cumulative mortality rate of over 80% (Zhang et al, 2021). However, there were few reports, which showed the molecular mechanisms of interactions between Vibrio alginolyticus, Aeromonas hydrophila and C. quadricarinatus .…”
