How to Build a Big Fish and Crayfish/Crawfish Pond in your Backyard

Building/digging a big backyard pond. The digging of the pond/dam required a big excavator. It took 2 days to build/make the pond. Size of the pond is 21x12x5 meter or 69 feet x 39 feet x 16 feet deep at the deepest part. No rubber pond liners or plastic pond liners needed since bottom is old sea bottom clay and sand. The rest includes macadam, air pump for oxygen, filter. Total cost $1400!
My pond is mainly for Crayfish Farming. Crayfish ponds should be located in flat, open areas, and the soils should have sufficient amounts of clay. Adequate water sources should be available. Clay loams, sandy clay loam and silty clay loams are satisfactory soil types. A clay soil is necessary to hold water and to maintain the integrity of crawfish burrows. I also added lots of old roof tiles for the crayfish/crawfish to hide under.
I breed the swedish Noble Crayfish (flodkräfta) they are red listed, only 5% remains in swedish lakes and rivers. The imported american signal crayfish carry a fungus so lethal to indigenous crayfish that it has nearly wiped them out. Signal Crawfish are now forbidden to put out in any swedish water. I also have Koi fish in the pond.
