A review of juvenile redclaw crayfish Cherax quadricarinatus (von Martens, 1898) aquaculture: global production practices and innovation

Abstract

The Australian Redclaw crayfish, Cherax quadricarinatus, has been the subject of aquaculture development for more than 3 decades. Farm production from Australia and from around the world for this species has been relatively low, as suitable production technology continues to develop. The production of redclaw juveniles for the purpose of stocking to ponds for on-growing to marketable size, has been a particular constraint and new approaches to breeding and mass production of craylings have provided renewed impetus to industry expansion. This paper reviews the literature concerning redclaw juvenile production and provides a status report of current practices and innovations that may support further expansion of redclaw aquaculture.

Microbial pathogens of freshwater crayfish: A critical review and systematization of the existing data with directions for future research

“…in 8 species of the recorded potential hosts pathogenicity has been observed). By far, the most studied species was Cherax quadricarinatus (von Martens, 1868) (57.1% of all entries), a species of high aquaculture interest (Rigg et al., 2020; Saoud et al., 2013), which resulted in the discovery of a number of C. quadricarinatus ‐specific viruses (Table 1).…”

The redclaw crayfish: A prominent aquaculture species with invasive potential in tropical and subtropical biodiversity hotspots

“…Having the appearance of a lobster, it is positioned at the premium end of the crustacean market spectrum (Bitomsky 2008). Although redclaw is advantaged by its relatively uncomplicated reproductive biology, the reliance on natural reproduction to generate juveniles for grow-out purposes is inefficient, being one of the main bottlenecks for greater production (Jones & Valverde 2020;Rigg et al 2020). As a result, redclaw aquaculture was soon considered a niche sector of the aquaculture industry, producing low volumes for local markets with accompanied economic interests (Ruscoe 2002).…”

“…As a result, redclaw aquaculture was soon considered a niche sector of the aquaculture industry, producing low volumes for local markets with accompanied economic interests (Ruscoe 2002). Despite these objectively beneficial aspects and having been 'heralded as an excellent candidate for aquaculture' in Australia (Rigg et al 2020), redclaw aquaculture industry, within the country and elsewhere, has developed relatively slowly since the late 1980s. In Australia, redclaw farming industry, composed of a great number of small enterprises, has not lived up to early expectations and predictions, and production has remained relatively low (Lawrence & Jones 2002;Rigg et al 2020).…”

The cost of setting up and maintaining redclaw aquaculture facilities remain noticeable (Ruscoe 2002).…”

Morphological and molecular characters of Cherax quadricarinatus (von Martens, 1868) from Sermo Reservoir and Tambakboyo Retention Basin, Daerah Istimewa Yogyakarta, Indonesia

“…It's distributed almost all over the world, especially in tropical countries, and commonly used in the aquaculture industry. In 1987, crayfish culture was began in Queensland, Australia, and this industry becomes developed, followed by growth in aquaculture technology (Rigg et al, 2020). The crayfish trade has grown since the mid-1990s, and around 30 crayfish varieties have been sold, used as aquaculture commodities in several countries around the world.…”
