However, introducing gas into fixed positions can easily lead to uneven distribution of oxygen in the water body. The water flow and gas diffusion rate at different positions in the breeding pond may cause higher oxygen concentrations in some areas and lower oxygen concentrations in other areas, thus affecting the growth and health of the shrimp fry.
