![]() ![]() Requires low protein diet, not reliant on fishmeal.Potential for selective breeding many wild population strains.Breeds easily, with no larval stage development.Its adaptation to the natural habitat has generated a host of biological attributes that are well suited to aquaculture, as summarised below: Redclaw display a strong tendency to move upstream to the preferred habitat, and to avoid being stranded in the lower river reaches that often dry up in the dry season. These are flushed seasonally with monsoonal wet season rains, which may wash the redclaw downstream. Its preferred habitat is in high turbidity, slow moving streams or static water holes (billabongs) that characterise the rivers in that region. ![]() ![]() Redclaw is native to the upper reaches of rivers in northeastern Australia, and in Papua New Guinea. Its texture and flavour compares very favourably with commonly eaten marine crustaceans and, having the appearance of a lobster, is positioned at the premium end of the crustacean market spectrum. It is physically robust with broad geographic potential, has a simple life-cycle and straightforward production technology, requires low protein diet and is economic to produce. Redclaw benefits from a host of physical, biological and commercial attributes that make it an excellent candidate for aquaculture. Redclaw proved to be well suited to cultivation, and the redclaw aquaculture industry was born, developing quickly and spreading throughout northern Australia, and soon afterwards overseas. Although well known to the local inhabitants of this isolated region, it remained effectively unknown to the rest of the world until the late 1980s, when it was trialled for aquaculture. Scientific Name: Cambarellus patzcuarensisThe red claw crayfish ( Cherax quadricarinatus), referred to throughout the rest of this fact sheet simply by its Australian synonym "redclaw", is a tropical species native to the rivers of north-west Queensland and the Northern Territory in Australia. Feed a variety of foods including: blanched vegetables (carrots, spinach, peas, zucchini, squash, etc.), spirulina tabs, artemia, krill, tubifex worms, white worms, chopped earthworms, blood worms, commercial flake and pellet foods. They are not aggressive towards fish, plants or other crayfish, but may predate on extremely small fish or fry. Like most crayfish, the Orange Dwarf Crayfish is an omnivore and will eat a variety of decaying plant matter, meaty foods, detritus and even a very small slow swimming fish if he can catch one. Fish species like Loaches or many Cichlid species should be avoided as they will feed on moulting and young crayfish. Hobbyists looking to keep multiple specimens should make sure that their is a hiding place for each specimen in order to limit aggression and provide a comfortable environment. ![]() Orange Dwarf Crayfish have very minimal husbandry requirements however, an ideal setup would contain a soil/gravel substrate, rock or driftwood hiding places, some plants and a basic filter to maintain water quality and oxygenate the water. Overall this species is very peaceful and should not bother live plants, fish or other inverts unless very hungry or if the fish or invert is extremely small. German breeders were able to combine multiple strains of Cambarellus patzcuarensis to obtain the wonderful orange coloration and small size of the Orange Dwarf Crayfish. The Orange Dwarf Crayfish is a wonderfully attractive selectively bred Crayfish that is priced for its coloration, temperament and small size. The Orange Dwarf Crayfish (Cambarellus patzcuarensis sp. ![]()
