What You'll Learn
Yabbies are found in swamps, streams, rivers, dams and reservoirs
Yabbies, also known as the common yabby (Cherax destructor), are native to Australia. They are found in various habitats across the country, particularly in the south and east. Yabbies are highly adaptable and can survive in a range of aquatic environments, including swamps, streams, rivers, dams, and reservoirs.
In terms of geographical location, yabbies are commonly found in the states of Victoria, New South Wales, and South Australia. They are also present in southern Queensland and parts of the Northern Territory, and occasionally in Tasmania. Yabbies have even been introduced to Western Australia, but this has led to concerns about their impact on native crayfish species in the region.
Yabbies are freshwater crustaceans and are often found in low to medium elevation waterways. They favour swamps, streams, and rivers, where they can burrow into muddy beds and remain dormant during dry conditions. Yabbies are nocturnal and feed on algae, plant remains, and opportunistically on animal or fish remains.
Additionally, yabbies are commonly found in farm dams and reservoirs. These habitats provide ample opportunities for yabbying, the popular pastime of catching yabbies. Yabbies are an important food source for many Australians, particularly those in rural or inland areas, and are considered a delicacy in some regions.
The adaptability of yabbies is further demonstrated by their ability to travel across wet land in search of new homes. This characteristic has allowed them to expand their range and establish themselves in various aquatic habitats across Australia.

They are a popular species for aquaculture
Yabbies are a popular species for aquaculture, although their burrowing can destroy dams. They are found in many ephemeral waterways and can survive dry conditions for several years by lying dormant in burrows sunk deep into muddy creek and swamp beds. They can also be found on private property in farm dams, but permission to fish must first be obtained.
Yabbies are an important dietary item for platypuses, water birds, and Australian native freshwater fish such as Murray cod and golden perch. Catching yabbies, or "yabbying", in rivers and farm dams is a popular summertime activity in Australia, particularly with children. The most popular method involves tying a piece of meat to a few metres of string or fishing line, which is then fastened to a stick on the bank, and throwing the meat into the water. The string is pulled tight when a determined yabby tries to make off with the meat. The line is then slowly pulled back to the bank, with the yabby maintaining its hold on the meat.
Yabbies are less commonly eaten in Australia than prawns and other crustaceans, but they are consumed much like crayfish in other countries. They are usually boiled and eaten plain, or with condiments. They are also sometimes served in restaurants, where they may be prepared in salads, ravioli, pasta, etc. Prior to cooking, it is advisable to "purge" the yabby in clean water, which helps to clear the gut of any muddy flavour, resulting in sweeter-tasting meat. In New South Wales, yabbies can be sold live at some fish markets such as Sydney Fish Market.
Demand for farmed yabbies is much higher than supply, with estimates of a latent demand five times higher than the current national supply of 300t/pa. Opportunities for expansion of the industry are, therefore, very attractive. Growers are investigating new production methods to increase yabby production, such as hybridisation (monosexing) and integration or polyculture with other crops.

Yabbies are native to Australia and are considered a delicacy
Yabbies, scientifically known as Cherax destructor, are native to Australia. They are a type of freshwater crayfish found in swamps, streams, rivers, reservoirs, and farm dams at low to medium elevations. Yabbies are common in Victoria, New South Wales, Southern Queensland, South Australia, and parts of the Northern Territory. They have also been introduced to Western Australia, where they are considered an invasive species.
The word "yabby" originates from the term for freshwater crayfish in several Aboriginal Australian languages spoken in what is now Victoria, including the Wemba Wemba and Woiwurrung–Taungu languages. Yabbies are an important part of the diet for some Australian native species, such as the platypus, water birds, and freshwater fish like Murray Cod and Golden Perch.
Catching yabbies, or "yabbying", is a popular activity in Australia during the warmer months, especially for children. Yabbies are typically caught in rivers and farm dams using various methods, such as nets, traps, or baiting with meat. Local fishing regulations must be followed, and it is important to obtain permission when fishing on private property. Bag limits apply in most states, with daily limits on the number of yabbies that can be caught.
While less common than prawns and other crustaceans, yabbies are considered a delicacy in Australia. They are often referred to as "inland lobster" and are prepared in a variety of ways, including boiling, salads, ravioli, and pasta. Yabbies have gained attention in the gourmet scene and can be found on the menus of restaurants. Prior to cooking, it is recommended to "'purge' the yabby in clean water to improve its flavour."

They are also found on private property, but permission is required to fish
Yabbies are commonly found in the wild in Victoria and New South Wales, though they also occur in Queensland, South Australia, Western Australia, Tasmania, and throughout parts of the Northern Territory. They are a vulnerable species of crayfish, though their populations are strong and their habitats continue to increase.
Yabbies are often found on private property in dams, creeks, rivers, and reservoirs. Permission is required to fish for yabbies on private property. This is because yabbies are known to destroy dams by burrowing through walls, so many farmers are not keen on having them on their land. However, some landowners are happy to allow people to catch yabbies on their property. There are even companies that will organise yabby fishing on private property for a fee.
When fishing for yabbies on private property, it is important to be aware of local fishing regulations. For example, in South Australia, the bag limit is 200 yabbies per day, and all females carrying eggs under their tails must be returned to the water. In New South Wales, the same rules apply, with a bag and possession limit of 200 yabbies per person.
There are many different methods for catching yabbies, including various types of nets and traps. One popular method is to use meat bait tied to a line. The line is thrown into the waterway and anchored to the bank. When a yabbie tries to take the bait, the line is slowly pulled out of the water, and the yabbie can be scooped up with a net. Another method is to stir up the muddy creek bed with a stick so that the yabbies cannot see out, then dangle a piece of bacon about one foot deep in the water.

Yabbies are invasive in Western Australia and Tasmania
Yabbies, scientifically known as Cherax destructor, are large crayfish native to southern Australia. They are found in many ephemeral waterways, including swamps, streams, rivers, reservoirs, and farm dams at low to medium elevations. Yabbies are primarily nocturnal detritivores, feeding on algae and plant remains at night, but also consuming fish or animal remains during the day. They can survive dry conditions by lying dormant in burrows sunk deep into muddy creek and swamp beds.
In their native range, yabbies are a popular food source and are farmed for consumption, considered a delicacy. They are also used as live bait for fishing and are becoming more popular in research projects involving lobster-like shellfish. Additionally, they are raised as pets and are a common species for aquaculture and in aquariums.
However, outside their native range, yabbies have been introduced to several regions, including Western Australia and Tasmania, where they are considered invasive species. Yabbies were first transported to Western Australia from Western Victoria in 1932. Due to their hardy nature, rapid growth, and adaptability, they pose a significant threat to native Cherax crayfish species in these regions, such as gilgies (Cherax quinquecarinatus).
In Western Australia, yabbies have successfully displaced native crayfish species and are now established as an invasive presence. In Tasmania, the introduction of yabbies is more occasional, but the species is still considered invasive due to the island's fragile ecosystem. The ability of yabbies to adapt to changing habitat conditions and their broad environmental tolerances contribute to their invasive nature.
