Two yabbyculture QUESTIONS: 

  1. What diameter do the pipes or pots need to be -- and how deep -- to protect the yabbies from themselves?The narrower the pipe the more I can fit into one space. You use netting, I see, for the fingerlings.
  2. I assume I can use 50mm hole (large hole) chicken wire so that I can grow  plant stem through the holes, right?

I've kept both redclaw and western blues.  Both are hellishly aggressive when they shed - they secrete a hormone that drives the others crazy and they fall on the new soft shells.  The secret is lots and lots over cover like pipes, pots, rocks etc.  And yeah, chicken wire every opening.

A bathtub yabbie tank sounds like a great idea Dave. If you wish to use redclaw crayfish for growing out from a smaller caught size, you can catch them at lake Samsonvale & Summerset.

I've kept them in a pond before, and used pvc pipe to provide as much individual housing. It is best to chicken wire any way out, preventing the vertical escape paths as well, even if it seems impossible. They were very aggressive with each other.

They love earthworms and veg, can climb vertical and upside down when out of the water, survive out of water for days, will leave on mass if an eel enters the same body of water. 

I never got numbers from breeding, but by catching a female with live young underneath and raising many from that point. I had many losses from them fighting amongst themselves as the redclaw grew.

I've seen them breed well in a very long and narrow floating raft Aquaponics growbed (I think about .5 x 4 metres). They trimmed the roots of the many of the plants above (which still looked healthy).

The biggest drawback I found is the need to keep them in low numbers, but the end result being luxury food makes it worth while to have a go.

Idea enters head. Seems feasible....

Does anyone have any experience of yabbies in a backyard pond?

I've just renovated my garden pond system -- I have 3 at the moment -- with growing more edible water plants in mind.

Looking at the bathtub I hope to convert to a pond, I thought, 'why not raise yabbies?'

Tick a lot of boxes does yabbies. 

Aquaponics per se is not my style. The pump for instance. But a yabby is a survivor of drought shallows and murky deaths so long as you keep up the oxygen in hot weather, the  water temp below 23 and the pH within a certain but wide range.

Of the ilk -- freshwater crayfish  -- there are around 100 species in Australia. OVERVIEW HERE.

Each animal requires about 30-40 cm area with places to hide from the other crayfish. The most commonly farmed on the east Coast is, of course, the yabby. 

Grew up around yabbies on my uncles' farms and yabbying in the dams was a family tradition. 

Good overview HERE.

One drawback is that they can be escapologists...ok except two of my ponds are made from plastic sheeting and they'd surely rip my engineering.

If it's helpful, Rob and I could organise to come look.  We have quite different approaches to aquaponics, so maybe one of us might say something vaguely useful (although, knowing us, I doubt it - LOL!).

How would a dedicated garden visit suit you Angela? There's lots of interest on this site as you know. Can be as small as you want, getting several experienced members together to discuss your setup could be useful for you and for them.

Have a talk with Dianne Caswell on this site (you have to ask her to 'friend' you first, that's the way this site works. You can have a private convo via private messaging.

Uploading photos is a snip. See this menu bar on the text input window?

Choose 2nd from left (image) navigate to where the pic is on your computer and hit upload.

Make the pix about 200-400kbs for those with slow connections.
