Stating the VERY obvious - please remember that if your plants are not going well, it might be a good idea to test your water.  I eventually lost a fish, tested, corrected a big PH imbalance and surprise, surprise - the damn plants have also taken off again!  *facepalm*  It is so very obvious in hindsight.

I wish they would.  Tilapia in endemic through most of our waterways now days. They are one of the few fish that breed well in captivity.

Seems a wasted resource like carp are tho there is some use made of carp.

Tilapia do you think that eventually they will give up on eradication and start to farm like in other countries .

After pursuing more info, I think bathtub yabbies are do-able.

I'm fixing to start with an opera house net and fishing a friend's dam...around here, they are all actually lagoons. 

Grow on from there. If no local crustacean fauna is on offer, I'll get my initial supply from pet shops.

As per usual, water quality and oxygenation are the major management protocols, but I'm thinking I'll begin in very hands-on mode without a pump. 

I'll water my seedlings with the water I draw from the tub and replace it as per aquaculture norms.

If one tub works, I'll get another...and if that proves practical, I'll get a further tub....

Cheap.

Feed 'em kitchen refuse. The advantage there is that I now give the chooks the kitchen stuff, but I really don't want to up my poultry numbers as we don't eat many eggs.

The other critter I'm interested in is the fresh water mussel.

Edible. Maybe a bit tough. But a water cleanser.

LOL - I used to keep them indoors in a tank with a lid.  The lid had one corner cut away to allow electrical cords etc in.  The buggers used to climb up the cord and escape.  I'd find them all over the house.

Chicken wire, Elaine? Yabbies are escapologists... They are the bantams of the underwater world.

Fascinating stuff! But what use is the chicken wire?

The pipes and pots should be a range of sizes.  You want small ones for young to hide in where the big ones can't access but you also need bigger ones for when the larger crays moult.

Ah... you are going to grow directly in the tank?  I'd probably try to use a floating raft of old styrofoam and then chicken wire between rafts.  Remember, the bigger the gaps then potentially the more yabbies you could lose. 

You will still need to aerate and clean the water.  I do it by using a fish filter (a normal old style aquarium one would work well).

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?
