How to judge the floating head of fish?
Judgment of the floating head of the fish is based on the time when the fish began to float, the location of the floating head, the size of the floating head, and the type of floating fish.
1. Floating head. Usually occurs when the sun has not yet come out, the fish moves in the center of the pond and the surface of the upward wind, visible bursts of water. The dissolved oxygen in the pond water is 2~3 mg/L, which is normal floating head.
2. Lightweight head. Mostly occurred at dawn, fish in the center of the pond and the water on the upside, the wild fish floating in the pool, the area is not very large, floating fish clusters, quickly fell after the sink. The dissolved oxygen in the pond water is about 2 mg/l, which is also a normal floating head.
3. General floating head. The start time of the floating head is 1~2 hours before the dawn. Pool fish are concentrated in the middle of the pond. The area of ​​the floating head is relatively large. When the fish is not disturbed, the fish is often on the sidelines and quickly sinks after being frightened. The wild fish by the pool has been in a state of heavy floatation. A small amount of wild fish can be found to be out of balance, but there is no dead fish. The dissolved oxygen in the pond water at this time is below 2 mg/l, which is the normal floating head limit.
4. Heavy float head. The floating head begins around midnight. The floating head spreads from the middle of the pond to the edge of the pool. Almost all pool fish are in anoxic state and are not sinking after being frightened. Wild fish have been found dead by the pool. The amount of dissolved oxygen in the pond water is in the range of 1 to 1.5 mg/l. The situation is already very dangerous. High-speed oxygen should be immediately sprinkled to the surface of the pond.
5. Pan Tong. The floating head started earlier and the water quality was bad. On the shore, the smell of stench from the pond could be smelled. Pool fish all floating heads, rapid breathing, swimming weakness, and found that the number of dead fish in the pool gradually increased. At this time, if oxygenation measures are not taken in time, there is a danger that the fish will be completely destroyed.
