Many crayfish ponds are shallow and not aerated. Shallow pond usually mix top to bottom due to wind action. Crayfish in deep ponds without aeration will inhabit the top oxygenated zone or layer similar to the invertebrates and fish. Where in SE MI are you? There are a few papershell crayfish sources in NW Ohio.
