Your welcome. The only issue I have found with this setup is ease of feeding.

Looks like an effective setup for mass-production, but it's not something I'd feel right about doing to any living animal. They don't have much space to move around, reminds me of some of the "puppy mills" I've seen on television. Granted, crayfish aren't anything like dogs, but still...

I don't know the specifics of Cherax species, but burrowing species are quite happy in a cramped burrow and many other species prefer to spend the vast majority of their lives underneath rocks.

So they may not need quite as much space as we generally want to give them. Of course, more room is always better, but the crays may not really care about the cramped space as long as they are getting clean water and quality food.

Edit: This thread is really going somewhere. As I look forward to my future need to study development and reproductive behavior in a controlled manner for research, I am definitely going to have to work this sort of thing out.

Yeah its definately not a new idea. Many people have come up with great cheap ideas.

How temperary are these homes? I don't feel it is healthy for them to be confined to a small space for long periods of time either

The proof is in the pudding - are they growing rapidly without health problems? Do they reproduce readily? Then they're OK.

Exactly... many of the species produced in this way are burrowing species. They live in smaller spaces with much worse water conditions than they would ever see in there. This type of system is used for breeding purposes only. Usually for food.

Thank You for the the Links, there are alot of good ideas to think about .
Before I finish my new Invert Room.

If you think production is the only measure of success, then visit a "modern" chicken or turkey farm. That is what this looks like to me. Looks like a puppy mill for crayfish.

The Betta tanks looks like a good idea .
Lets say for Dwarf Cajun "Blue".
You can sort the young out by color, add a little leaf litter.
Limit the number per section, so there will not be a competition for food. and get the maximum growth rate. and then sort them out by sex.

And you do not have to search all over a tank for them.

If you looked as the links, there is a good idea of how to heat several tanks with 1 Heater. unless you have a heated Invert. Room.

Or, with the bottom sump tank and a auto water change set-up. You would never have to change water, manualy again.

Even though you do not like the puppy mill approach, there are alot of good ideas.
