Got an aquaculture facility that’s not operational or not making the amount of money you desire. Why not lease your farm or your ponds? We have clients in desperate need of ponds now.
Aquaculture is the fastest growing primary industry in Australia. Demand for aquacultured produce is skyrocketing and new production methods are increasingly improving profit margins making modern land based aquaculture an increasingly lucrative enterprise.
Unfortunately, difficulties in obtaining approvals for new ponds and the ensuing time delays in receiving approvals and then building ponds makes the interest level in existing ponds extremely high.
Existing yabby and fish ponds are wanted now so that large scale commercial farmers can expand their production by using your ponds. They come to you, use their staff, their equipment and technology, to get your ponds into commercial production. They don’t need you to do anything at all, you do not need to expend one cent towards the enterprise. They just rent your ponds or property nothing more.
If you have ponds not producing much or haven’t been in production for years then contact us for further details. Perhaps we have a lucrative solution to create a substantial, reliable income without any effort or expense from your end.

NSW Aquaculture Association in partnership with “Yabby Dabba Doo” Yabby Farm and Aquatic Engineering Australia is holding a yabby farming field day on Saturday the 8th August, 2015. Everyone is invited to share in this education and information day.
The days theme, is the commercial aquaculture of yabbies (Cherax destructor) in purpose built earthen yabby ponds. Join us around the ponds to see how they are constructed to suit the yabbies requirements for maximum production. These are not farm dams but commercial yabby ponds. See how to construct commercial earthen ponds, control their overflows and make the ponds gravity drainable at minimal cost.
Once yabbies are captured they need to be held ready for sale. You need somewhere to store yabbies for a week or two ready for sale and be able to purge the yabbies on demand. See a simple commercial purging recirculating aquaculture system in operation; see how it’s constructed and how you can build yours at home. Discuss the pros and cons of this basic construction with Paul Van der Werf, one of Australia’s leading experts on recirculating aquaculture systems.
When you start growing commercial quantities of yabbies at densities far greater than that which occurs naturally in nature then perimeter fencing of your ponds becomes an important priority. Commercial yabby ponds need external perimeter fencing to ensure yabbies don’t wander from the ponds and to keep predators like turtles and eels from getting into the ponds. Join us to see the fencing and discuss the options and requirements.
One of the major predators of yabbies are birds. The main culprits are cormorants or shags which can devastate commercial yabby ponds. The easiest remedy is to net your ponds. Join us on the day around the ponds to see the bird netting erected over the ponds. See how it’s erected, and discuss alternatives with the experts.
First thing in the morning we will be setting traps in the ponds. We will be using a variety of traps from those used by recreational fishers to the special traps only used by commercial farmers. The traps will range in size from the small box traps for catching small bait yabbies to the large super traps for catching bulk loads of 20-50 kgs/trap. Later in the day we will harvest the yabbies from the traps. See how it’s done and what you can catch in the different traps.
For commercially viable yabby production you need to add shelter to the ponds. Yabbies only use the floor of the pond which limits the number of yabbies which can physically survive in the pond. If you add shelter to the pond you can double, triple or quadruple the production from that pond. Join us to see the types of shelters used and how they are set for easy removal from the ponds and additionally used for juvenile harvesting etc.
A clean reliable water supply is an essential requirement for any commercial aquaculture facility. Aquatic Engineering Australia will be demonstrating their “Ultra Filtration Mobile Unit”. Join us to see the unit in operation with demonstration of its sediment removal capability. See how this demonstration unit can turn turbid dam water into clear, clean water.
Our Aquaculture Policy Officer from Fisheries NSW will be there to discuss the government requirements in getting started. Find out all you need to know and it’s a great opportunity make contact with the man you will need to lodge your application with.
Once you have grown and harvested your crop of yabbies, you will need to sell it. See the different size yabbies the different markets require. Discuss the markets for each size and grade of yabby, and the current market prices for your produce. Learn where you can sell yabbies and what you can expect in return for your produce.
This is a great opportunity to meet with some of Australia’s leading industry experts. All are there to answer all your questions. (Industry consultants can charge $100-200/hr for consultancy; you have them there at no extra charge so make good use of them).
There will be drinks and a sausage sizzle or similar after the event so another opportunity to stay back and network.
Key speakers include:
Jamie Williams, Owner of “Yabby Dabba Doo” Yabby Farm and “Marron-U-Wanna” Marron & Koi Farm in WA.
Rob McCormack, Research & Aquaculture Director, Australian Aquatic Biological P/L and Secretary NSWAA.

As an industry consultant and a member of the original CSIRO Steering committee for the CSIRO/RIRDC CSA-17A Super Yabby Research project I am still involved with requests for further information and participation in current projects relating to the CSIRO SUPER YABBIES and yabby farming generally.
In addition to my commercial ventures, recently I had cause to review the project and provide information for a forthcoming Yabby Farming Field Day at Griffith NSW being held by the NSW Aquaculture Association Inc. (NSWAA) www.nswaqua.com.auin March 2015. As secretary of the NSWAA I compiled the following. Some of the following is what you will also find on the NSW Aquaculture site with a lot more commercial farming information added in this article. If you would like to see the NSWAA article http://nswaqua.com.au/super-yabbies-developed-by-the-csiro/ The NSWAA article contains all the scientific information, papers, photos and reports but only available to members via their member’s library. This article is more general information without the reports and scientific manuscripts.
Back in 1998 the CSIRO Livestock Industries at Chiswick near Armidale NSW self-funded a research project aimed at increasing the productivity of farms through genetic improvement of yabby stocks. Historically the CSIRO at Armidale (http://www.csiro.au/Portals/About-CSIRO/Where-we-are/New-South-Wales/FD-McMaster-Lab.aspx) started as a sheep research facility in the 1950’s. However, due to the decrease in wool and other commodity products that occurred in the mid 1990’s the CSIRO was looking for something sheep farmers could diversify into and identified yabbies/aquaculture as the option with the most potential. In mixed farming situations, risk spreading strategies such as diversification outside the traditional commodity mixes, can enhance economic stability and yabbies seemed ideal.
The research program was led by Dr Dean Jerry whose vision and dedication to the aquaculture industry drove this project. Dean was an industry hero at the time and had the full support of the NSW Aquaculture Association and Industry.
Dean started with an extensive search for naturally fast growing strains of yabbies. He finally selected 5 basic strains of yabbies from very diverse environments. From western Queensland, north western NSW, western NSW, the NSW Snowy Mountains and western Victoria yabbies were collected and sent to the CSIRO animal laboratories at Chiswick NSW.
Dean and his team started with these different strains of yabbies but found very early on that 2 of the strains grew exceptionally faster, compared to the others (Jerry et al. 2001). Different strains of yabbies from different populations have a remarkable variety of different genetic traits, some of these are advantageous and some are not so attractive. The main trait that the CSIRO was interested in was growth; they did trials between the different strains and selected the two fastest growers which showed the most promise. Now you can speculate on the reason for this but coincidentally both of the faster growing strains where from the upper reach tributaries of the Murray Darling Drainage Basin. Yabbies are native to the Murray Darling drainage basin of Australia and thrive throughout the whole basin. The Murray Darling Basin covers one seventh of the Australian continent, over one million square kilometres, it includes 20 major rivers including the 3 longest, the Darling 2740 kilometres, the Murray 2530 kilometres, and the Murrumbidgee 1690 kilometres.
The two strains selected came from the Warrego River in south west Queensland which is at the headwaters of the Murray River and the Tumut River which is at the headwaters of the Murrumbidgee River.
The research identified that there are significant differences in growth rates amongst wild populations of yabbies (Jerry et al. 2002). In fact the two fastest growing populations they evaluated grew up to 42% faster than the slowest one (which by the way is C. albidus destructor from the Wimmera region in Victoria). The Victorian yabbies, however, had longer tails than all the other strains. For commercial purposes tail meal is a major consideration as those that savour the flavour of yabbies want bigger tails to get more meat. However, for the CSIRO initial trials they were only selecting for growth
They selected the 2 fastest growing strains of yabbies (Cherax destructor) and in 2000 started a selective breeding program with these 2 varieties. They started with 28 families of yabbies plus controls (over 300 yabbies initially). The controls were grown with the selected families to ensure accurate results, but tagged to identify them. The idea was to use these selected strains as the genetic base for a selective breeding program to further improve growth rates and to use the controls to monitor the progress. The process was quite simple with single sire mating occurring in glass aquariums. This allowed full control of the breeding process and ensured that inbreeding was not a problem. Juvenile yabbies were then raised in the CSIRO hatchery till they were between 0.4 and 1 gram. The juveniles were then tagged with an elastomer insert and transferred to the outside ponds for the growth trials.
The CSIRO constructed 6 earthen ponds each 0.1 ha in size. The ponds are fenced and netted and are designed to replicate commercial yabby ponds, so results obtained will be the same as those received by industry. Typically for commercial yabby farming the minimum pond size is 0.1 ha and the maximum is 0.5 ha (see the book Commercial Yabby Farmer for further design details http://www.rbmaqua.com.au/bookshop.shtml)
The first F1 generation of yabbies at an average weight of 0.59 gram were stocked into the earthen ponds and grown for 78 days. Overall 62% of yabbies stocked survived and the mean weight of the crayfish harvested was 30.7 gram. There was a vast difference in individual size with for the males the largest was 52.6 gram and the smallest 16.5 gram. However, the bottom line is that the selected yabbies grew 14% bigger than the controls. The individuals both male and females with the best growth were then selected as broodstock for the next generation.
In 2001, the Rural Industries Research and Development Corporation (RIRDC) who are supportive of rural industries and had a bit of vision, agreed to fund the CSIRO for an ongoing 3 year research project. This was the same year the first generation of animals were evaluated and selected for growth and progeny. With a bit of support from the RIRDC and lots of interest and enthusiasm from industry and the community the CSIRO started on the second generation under the leadership of geneticist Dr Ian Purvis.
F2 yabbies were hatched in the glass aquariums, grown to an average weight of 0.43 gram, elastomer tagged and released into the ponds in the first week of January 2002. They were allowed to grow for 205 days this time till mid July which is the heart of winter. Survival this time was only 55% all up but a longer grow out time and two months of winter, plus the drought all took a toll. Mean crayfish weight this time was 70.1 gram with the smallest being 43.8 gram and the largest 133 gram. In 2002, this second generation of animals where harvested from the CSIRO earthen ponds and measured for 11 different characteristics (weight, carapace length, tail length, tail width and claw size, etc). The results were remarkable, in a nutshell the selected yabbies grew much faster than the standard control. As expected female yabbies grew slower than the males but still averaged a 10% increase in growth rate per generation. The big improvement, however, was in the males. Male yabbies in the first generation grew 14% faster than the standard controls. Male yabbies in this second generation grew 14% faster than the controls again. So, in just 2 generations they had a 28% increase in growth rates, imagine what this will be like in 10 generations time.
The best of the animals harvested in July were over wintered in an internal recirculation system and then bred to produce the third generation F3 which went into the ponds at 0.5 gram in mid December. They need to be 0.5 gram to allow tagging for identification to occur. Yabbies were grown in the ponds for 163 days and survival again was 55%. Average mean weight was 64.8 gram and ranged from 55.7 to 105.2 gram (Jerry et al., 2005).
The funding so generously supplied by RIRDC finished so the project wound up and Dean published a paper in 2005 on the genetic breeding program. The last harvest of the F4 generation proved hard to interpret as initial indications that this generation only had a 10% increase of growth instead of the 14% expected. The problem is that in the pond this time is a far greater number of yabbies than expected. Uncontrolled in pond breeding is a major problem that plagues the commercial yabby farming industry. Typically, yabbies can breed from a small size and only 5-6 months of age. A 10 gram, 24.5 mm OCL yabby can have 150 eggs. Generally, the smallest size yabbies harvested are 30 gram so if yabbies waste energy breeding and then thousands of extra yabbies enter the pond population then they consume resources further slowing the growth of the whole pond population.
It may be that with these improved strains that because they are growing so much faster, they are now also maturing faster, so breeding earlier and as they are bigger having more young when they breed and those young are growing incredibly fast, so the pond biomass just explodes which strains the available food sources, limiting growth of the pond population as a whole except, for the more aggressive dominant males that still get more than their fare share. This may account for the vast differentiation in size with the F4 generation which varied from 40 gram to 180 gram.
Typically for extensive and semi intensive yabby farmers you would harvest your yabbies by using yabby traps. In NSW it’s traditionally the opera house traps but not the standard ones with a steel ring entrance, commercial farmers use opera house traps with NO ring. These type traps are only available for commercial farmers and not for use in public waters as they catch everything; turtles, fish, platypus, etc. Commercial farmers can purchase no ring opera house traps here, http://www.rbmaqua.com.au/aqua-shop.shtml
The CSIRO research was spectacular and an eye opener for many yabby farmers. Unfortunately, the yabby industry as a whole has not been genetically improving their stock in a consistent manner; in fact most are doing the opposite. Yabbies are in tremendous demand and as a rule every yabby farmer in NSW and Victoria just never has enough yabbies to meet the overwhelming demand. Most farmers catch their yabbies in opera house traps, these traps tend to capture the larger yabbies first. There is a certain amount of yabby etiquette in yabby ponds and it is just common courtesy and safer for the smaller yabbies in the pond to allow the larger yabbies to have a feed first. Now yabbies by character are sneaky, so if a smaller yabby can pinch a bit of food whilst the big boys are not looking they will, but generally it’s the big boys that feed first as the males are the ones that grow the fastest. When you drop a trap into the pond you capture the largest fastest growing yabbies first and generally it’s large ones you need, so these yabbies tend to get sent off to market and any small sneaky ones capture returned to the pond.
Unfortunately this leaves the smaller slower growing yabbies to breed so you are actually selecting for smaller slower growing yabbies. This is a common problem on most farms that do not have specific broodstock ponds or selective breeding programs.
Those semi-intensive yabby farms growing yabbies in purpose built ponds would stock with a set number of yabbies, grow-out for a set amount of time and then drain harvest the pond. This type production would achieve production of approx. 2500 kgs/ha/year. (see “The Commercial Yabby Farmer book http://www.aabio.com.au/products-page/ )
The CSIRO finished the research project and printed the final report in April 2006 (Purvis, 2006). The CSIRO to help the yabby farming industry not only release the research results to industry but they released the Supper Yabby. This was a fantastic boon for industry as these F3 and F4 generation yabbies are like getting a stud bull or ram. You can use these to breed up a whole new generation of improved super yabbies. Just one good male can look after dozens of females, so a few hundred improved yabbies to every farmer could go a long way to improving the industry as a whole.
Unfortunately, Fisheries NSW classed the super yabby as genetically modified and had concerns for the indigenous species of crayfish if the super yabby escaped into the wild. There are over 140 different species of freshwater crayfish in Australia (go to http://www.aabio.com.au/crayfish-list/ for a current list of all species) and most are nowhere as tough and hardy as the common yabby let alone a super yabby. In NSW the common yabby Cherax destructor is already creating havoc where it has been translocated into eastern drainages (Coughran et al.,2009; McCormack, in press). For industry to be allowed to culture the super yabby in earthen ponds strict environmental regulations were imposed by Fisheries NSW to protect the environment to ensure the super yabbies never escaped into the wild.
As a thankyou to the NSW Aquaculture Association for their support and assistance over the course of this research project the CSIRO only released the super yabby stock to members of the NSWAA. With the strict Fisheries NSW restrictions and prior inspection of the properties by Fisheries to ensure the premises complied with the new regulations only 5 commercial farmers received this incredibly valuable super yabby stock. Now in 2014 only 2 of those farms/NSWAA members have maintained the genetic integrity of their super yabby stock, one here in NSW and another in Victoria. Neither of these two farms are selling their “Super Yabby Stock” but holding it for future development. However, one of these farms is on the verge of a major project to revamp the Super Yabbies and achieve the industry holy grail of an F10 generation.
In NSW we have a “Class E” licence from Fisheries NSW that allows individuals to harvest yabbies from multiply sites. Yabbies (Cherax destructor) are indigenous to western NSW and most farm dams can support populations. Typically, farm dams can be harvested at 300-600 kgs of yabbies per hectare of surface water per year. So if you have 10 only 1000 square metre surface area dams, this equates to a hectare in total. If you have 10 properties each with 10 dams then you can harvest 3000-6000kgs of yabbies per year. With a market price of $20/kg there is the potential for a nice living to be made.
It’s not so easy as not every dam has yabbies, some are full of carp or spangled perch, etc. and only have a few yabbies. Distance is a big obstacle, as vehicle and fuel costs are a major consideration. Also weather is one of your greatest threats, droughts dry dams out, and wet weather makes driving through paddocks to get to the dams impossible. Add the fact that this is just a harvesting operation and most Class E operators have not learnt from the CSIRO research. They just trap, which selects the larger yabbies and harvest them so leaving the smaller yabbies to breed thus year by year slowly reducing the volume of harvest.
Your next option is to have an extensive yabby permit from Fisheries NSW for your own property. Known as a “Class C” extensive aquaculture permit only allows you to grow and harvest not to feed your yabbies with artificial foods. This means you can manage your yabbies and dams better but only at natural levels as without additional food you are limited to the natural food available and production of the 600-800kgs/ha/year would be the maximum. You can however do some selective harvesting and actually, increase your harvest every year.
Your final option is for the professional farmer that wants to maximise his yields and use artificial feeds to boost his production. This requires a “Class D” intensive aquaculture permit from Fisheries NSW and comes with a number of restrictions to ensure the environment is protected. When you add food to a pond there is a greater risk that something can go wrong. If for example you add too much food and it’s not eaten then you can pollute the water. That polluted water is not allowed to escape the farm and must be irrigated, etc. Additionally, you are now growing higher densities than occur naturally and the risk from disease becomes a problem. Yabbies are relatively disease free but the same permit conditions apply regardless of species and fish can get any number of diseases; if they do the licence conditions ensure that the disease does not escape and impact the fish in the local creek, etc. The same goes for the CSIRO super yabbies, you would need a Class D permit for these with additional restrictions all aimed at protecting the environment.
The NSW Aquaculture Association is holding a field day at Griffith NSW in March that covers everything above. If you’re interested in yabby farming then you should attend.
If you’re interested in attending the Yabby Farming Field Day at Griffith NSW you can sign up here http://nswaqua.com.au/yabby-farming-field-day-griffith-nsw-13th-march-2015/ and we will send further information by email as it becomes available. Ill be chatting to attendants about yabby farming on the day – “hope to see you there”.Cheers Rob
