Backyard Aquaponics
A place to discuss aquaponics

I am hoping to be able to grow some yabbies next spring when I can catch some and I am trying to decide what to keep them in so I can redesign my system a bit.

How good are they at escaping? Do they stay put unless the water quality goes down or do they try and get out all the time? From what I have been reading around here marron are really good at getting out, but there isn't much on yabbies.

Would a bathtub be OK given it has a sloping end? Would something with straighter sides be better (like a plastic tub)? I am assuming they need to be in a separate tank to any fish if they are to breed or the young will get eaten.

Thanks,

Damn good - I had 2 in my outdoor system which even got past a cover I had on the system - then I had one in a classroom tank, and it somehow got out and landed up drying out over the weekend


Bathtuba are what I had, and it was easy for them to escape - my IBC's are proving escape proof SO FAR!... I now have 3 redclaw in one and so far they have not got out... deeper water would make them feel safer, especially if you provide adequate shelter and hidy holes for them

AS AM said.............Damn good!

i lost lots due to escape........ they tend to prefer their water with a tad higher PH around 8ish, but are OK at 7.5 and maybe a tad lower.

I would have thought a bath tub would have been ok AM, did you have an air line running in there?

they'll scale an air line in 30secnds!

the one monster i have in the indoor tank has not climbed up in ages, water must be nice Actually, i haven't seen him in a few days, now you've made me paranoid! Sometimes he does have abig feed and dissapear for a few days...........going to check!

no air lines in the old bath tub system, the overflow from tub to tub was plenty enough to up the DO... but I did have the pipes from my pump running out fo their tub...
I watch my biggest redclaw climb the outside of the pvc pipe I have running up the centre of my IBC (my airlift tube) - it is smooth, but he managed to get to the top... then had no-where to go so he dropped back down eventually... after I popped a cement building block in he seemed happier as he moved right in and has claimed it for himself.

yeh, gotta give them somewhere to hide

Thanks, sounds like a couple of blue drums cut in half should prove hard to get out of. Just need to keep pipes away from the sides.
