Backyard Aquaculture

This 15' long fish breeding set-up costs only a few hundred dollars. Fish will reproduce and survive all year while you remove the larger ones for eating. This is an 800 gallon pond (8' across, 4' high). The filter is a 50 gallon container (garbage can) that releases clean water pumped in by a small magnetic pump. The released water come in from the bottom, and is discharged from the top of the container so that the cleaned water falls as strongly as possible onto the surface of the pond. This action adds oxygen to the pond water.

The filter container has abundant small plastic, ball shaped pieces with lots of crevices for the healthy bacteria to thrive and collect the biological matter that comes from the pond as the water is pushed through.

A second pump for pumping air into the pond is important to keep much oxygen in the water as the fish population grows. Both pumps require very little electricity. All pumps whether rated for outdoor use or not, should be protected from rain, snow, debris like falling leaves. Keeping the pump clean and protective keeps fish breathing!
