How to judge the severity of fish gasping at the surface
To judge the severity of fish gasping at the surface, the main criteria are the time when the fish begin to gasp, the location of the gasping, the size of the water surface area where they gasp, and the species of fish gasping. 1. Dark gasping. This generally occurs when it is already daylight but the sun has not yet risen; the fish move about on the water surface in the center of the pond and on the upwind side, and bursts of splashing water can be seen. At this time the dissolved oxygen content of the pond water is 2-3 mg/L, which is normal gasping. 2. Light gasping. This mostly occurs at dawn; the fish are on the water surface in the center of the pond and on the upwind side, while wild trash fish gasp at the pond edge.
