Post subject:  YABBIE'S

I have had a fair bit to do with yabbies over the past 15 odd years, from trapping to breeding, recipe idea's and home farming.

Ive learnt a lot and read a lot in that time and was lucky enough to have a very resourceful father at a young age in relation to all thing yabbie and daming.

Yabbies are an interesting creature and their instinctual habits amaze me... even after all this time.

I currently own a number of yab's that I breed, examine and experiment with (not on) and record everything in a journal Ive had for about 4 years now. Ive consulted local land owners and we have some excellent results over the years.

I currently am writing a cookbook which hopefully will be released next year some time.

If anyone has questions or queries about yabbies, gilgies, koonacs or marron feel free to ask.

yep. It has a lot of info about the yabbies themselves too.

Noice! Growing up with dams full of yabs and marron all we ever did was boil em up and eat with thousand island and tabasco sauce. Nowadays I think I'm ready to broaden my horizons so can't wait for this book! Should be a good market for it too, especially in country bookshops, aquaponics shops and the like...

Will it have marron thermador in it?

The recipes can transition between most freshwater crustaceans, Ive never done a thermador, thats the one with the parcel of pastry surrounding the flesh mixture simo?

More of a sauce used with lobster or crayfish in the half shell, just thought it would be interesting to see a marron version. :learn:

Aah yes. Cant say Ive done an actual thermidor but many different takes on the butterfly'd shell/stuffed tail. More so mornays and cheese based sauces etc.

I like the sound of that, might give it a go. Ill give you a special mention in the book :thunbs:

We used to catch crayfish during my boating teenage years, I was chief deckhand :thumb: and anchor puller. We would cook them fresh with bacon mm yum.
I used to make the white sauce with a little sherry and parmesan cheese served in shell cut in half and as they say these days "plated up" and slightly grilled till the cheese bubbled and turned golden brown. Aaah memories!
The yabbies would make a delectable appertiser done in the same way, though more of a taster.

That sounds great Charlie!
First question...
We have had yabbies for a while, and presently have two IBCs for two sizes, but feel there should be a would you suggest grading them for maximum growth?

Hi peasants :wave:

Your spot on, grading is important but grading by size isnt the only thing to take into consideration. Ill explain..

Firstly a couple of points to keep in mind.. yabbie growth rates rely heavily on temp, 20-28deg being optimal and below 16deg and they enter a state of reduced metobolic activity, basically hibernation. Obviously aeration at higher temps will improve DO levels and water quality.

Also make sure your PH levels dont become to acidic, this will soften the exoskeleton and promote disease therefore reducing activity. Try keep it above 7 - 7.5.

Although nutritional requirements of yabbies is relatively unknown, I like to stick to high protein diets like aquaculture pellets, potatoe and lupins. A few worms and snails now and then are also a good addition. Just keep an eye on left over food as you would already know. I think farmers feed at around 3% per body wieght per day but I wouldnt fuss on that number for what you are doing.

Ok, in relation to grading, there are a few ways to go about it. I wont go into them all but the system I use is relatively simple. For this you require 3 tanks. A juvenile tank, a breeding tank and a grow out tank.

The juvenile tank is the most important. It will be home to the babies and berried females. Females are removed about 2-3 weeks after brood. This needs a complex habitat, I use lots of hides with pipe cut offs (its a good idea to close one end) and a massive bunched up length of shade cloth.

The breeding tank is home to 1 male per 3 females at a stock density of around 8-12 yabbies per 1m2 of floor space. Once again, hides are crucial. There will be carnage in this tank, its impossible to avoid. Move the males to the grow out tank regularly and eat the females after a couple of broods and replenish with young from the juvenile tank. Young females are good to go at around 20-30g.

The grow out tank is all male occupied, I stock this at around 30 per 1m2 of floor space. Also a haven for carnage but thats the way it goes... usually when they mault. Yabbies will grow faster in an all male situation and in fact research into mono-sexing and hybrid species is likely to intensify and increase production substantially over the next decade within the farming world.

Ive read some really good articles by an australian marine biologist Dr Craig Lawrence who bred a Cherax albidus with a Cherax rotundus which produced only male offspring, quite possibly might become the future of aussie yabbie farming.

More than what you asked for sorry but I hope this helps. :D

Wow, Charlie, that is great information-thanks! We did some grading over the size....but will rethink it all now, and get a juvenile tank....and check the pH.....Thank you so much for the detail! :thumb:

Great post Charlie, thanks for sharing that info :cheers:
