Backyard Aquaponics
A place to discuss aquaponics

There was a lot of discussion a while ago about growing redclawin an ibc(etc) on layers of shadecloth or other material. Just wondering if anyone has actually done it. Did it work? The idea was to increase stocking densities see below.

Thanks

Guess not

Not in aquaponics ,, but I know for pond culture vertical fencing is used. Like lots of fences using safety barrier stuff like what you see around man-holes.

we've got a stack of bread crates in an ibc, with a couple of bricks on top to stop them floating

I put about 30 redclaw in of varying sizes. There seems to be two large ones left. Which kind of defeats the purpose of providing extra "floor space" for them. We do have another 10kL tank liner waiting to happen, but... time and effort

Hi Jamie,

is it easy to get them to breed ??? or berry up ? I think I am going to have to doa heap of reseach into them as I think they would be fun to grow

no idea! they've been in there for over a year now, and no sign of berries or babies, but then I've not checked the gender of them either! I was kinda ignoring it until we got more space for them

I've had yabbies breed before, but it was almost by accident.
Yabbies trigger their breeding cycle based on a large water temp change to show summer to winter transition (or the other way, I forget)
I know nothing of redclaw, but hope they're similar or I'm wasting my breath
You can tell when a pair is going to breed. instead of being massively aggressive and territorial, one lets the other move in and cohabit.
Then the girl will lay eggs held under her tail, that she will constantly fan with water (to keep fresh? stop rot?) I have seen the male fanning too, but don't know what for.
The eggs slowly develop, (yes you can see the baby inside the sack forming) and then hatch, at this point they're tiny, and I have always lost them all.
Perhaps it is food related, perhaps cos they were in an aquarium with fish, perhaps cos I was heating the tank at the time I don't know. Maybe mum ate them all.
Were I doing it for AP I would take certain precautions, that as a young aquarist I did not.
