In captivity, for the best growth, Red claw crayfish need a good mix of meats and vegetation, where their feeds should contain protein at a level of about: The optimal food for juveniles is zooplankton. However, this is not recommended for hatchlings and juveniles as it does have adverse effects on growth and aggression. It means that they can eat about anything edible they come across.Īdult individuals will perform well even on a relatively low-protein diet with a high proportion of cheap plant material. Red claw crayfish are omnivorous and extremely opportunistic eaters.
Unfortunately, the same cannot be said about juveniles. No, they can just tolerate high stocking densities better when other crayfish species. Note: It does not mean that they are social. Behavior of Red Claw Crayfishĭespite their large size, adult Red claw crayfish are generally gregarious and non-aggressive, amenable to stocking at relatively high densities in the ponds. However, under optimal conditions, they can live up to 6 years in the tank. The lifespan of the Red claw crayfish is about 4-5 years long.
CLAWFISH PET PATCH
a red-colored patch on the outer margin of the claw (a trait of males), hence the common name.the presence of four distinct anterior ridges of the carapace,.The unique features of the Red claw crayfish include: In juveniles, the color pattern is a little bit different in usually ranges from light blue to light gray, mottled in white with whitish leg joints. However, in the aquarium trade, it is possible to find some other color variations with a greenish or grey tint. In general, this species has a dark blue body (carapace) mottled with beige and red/brown spots, with red leg joints. Males can reach a maximum weight of 500 g (1.1 lb) and females 400 g (0.9 lb). Description of Red Claw Crayfish Cherax quadricarinatus color morphsĬherax quadricarinatus is a large-sized crayfish that can reach 13 inches (up to 35 cm) in length at optimal conditions. In all cases, rocky habitat with plenty of caves for exploring, foraging, and protection during molting is their preference. However, were also found in freshwater irrigation channels, fast-flowing rivers and streams, and brackish-water lagoons. These crayfish prefer high turbidity and slow-moving rivers, lakes, lagoons, or static water holes. Note: Currently, Cherax quadricarinatus is considered as the 2 nd most cosmopolitan crayfish species globally, after the Red swamp crayfish (Procambarus clarkii). However, being a successful invasive species, it is now widespread globally out of its native range as a result of the aquaculture and aquarium trade.Ĭherax quadricarinatus has become successfully established in different aquatic ecosystems in Europe (the Iberian Peninsula), Asia (Singapore, Israel), South Africa,, Latin America (Ecuador, Argentina, Jamaica, Puerto Rico, Cuba, Mexico, and others), and even in Los Angeles, California (Lake Balboa). Redclaw crayfish, Red clawed Yabby, Australian Red clawed crayfish, Blue lobster, Blue yabby, Giant crayfishĬherax quadricarinatus is a tropical species of freshwater crayfish native to the Gulf of Carpentaria in northern Australia and southern New Guinea. This is one of the leading threats to freshwater biodiversity. The introduction and spreading of non-indigenous species of aquatic fauna has caused and still causes, strong ecological impacts in freshwater environments Unfortunately, aquarium releases account for many aquatic invasive species. Warning: NEVER release the Red claw crayfish (Cherax quadricarinatus) into the wild! This species is nationally and globally classified as an invasive species. Keep reading for more information on the Red claw crayfish, this guide covers details on its appearance, behavior, feeding habits, care, and lots more. Red claw crayfish are highly adaptable to various water quality parameters such as different levels of ammonia, nitrites, pH, hardness, alkalinity, temperature, and oxygen.
Cherax quadricarinatus, generally known as the Red claw crayfish, are commonly traded as pets.ĭue to its vibrant coloration, flexible diet, fast growth, high fecundity, and stress tolerance, Red claw crayfish can be an ideal low-maintenance candidate for large freshwater aquariums.
