Cherax quadricarinatus
A tier
Cherax quadricarinatus, the redclaw, is a tropical Australian crayfish farmed widely in warm climates for its rapid growth and distinctive red colouring on the claws of mature males. Meat yield is good; flavour is mild-sweet and suits Asian and Western preparations alike. It is a major aquaculture species from Australia through Southeast Asia and beyond. Steam, boil, or stir-fry with ginger and spring onion. Farmed redclaw often arrives frozen as whole or tails. Distinguish from red swamp crawfish by the broader Cherax body plan and claw markings when buying live.
