Feel free to make the pond larger than this if you can install systems to properly aerate and drain it. A lot of commercial farms operate multiple large ponds. Consider adding more once you get used to managing your farm.
Spreading some gravel over the dirt can help keep your pond compacted after you’ve begun using it. Businesses that are accustomed to laying concrete can help you settle the dirt too.
Make sure the drainage pipe isn’t covered. The concrete should rise slightly above it so water flows into it.
For larger ponds, you’ll need two or more paddlewheels set in the middle of the pond. This can also be helpful in case one of them fails. Aspirators can also be used, although paddlewheels are more effective for the size of pond needed by crayfish farms.
You’ll need about 150 hiding spots per 1,000 square metres (11,000 sq ft) of pond space. Be careful when filling the netting with degradable material. Avoid material that leaches toxins into water and change out plant matter when it starts decaying. [10] X Research source
If you want to fish for your own crayfish, consult your local laws to make sure it’s legal to capture and transport them.

Don’t forget to shake out the nets to find any lingering crayfish!
Transport the crayfish from the pond in a water tank. Avoid overloading the tank with crayfish and remember that they’ll run out of oxygen if you leave them in there too long.
A calcium level above 5 milligrams per litre (1. 8×10−7 lb/cu in) is enough to keep your crayfish alive.
Clean out the pond at least once a year.
