How to give first aid to fish fry coma during transportation

In the course of transportation, fish species often consume too much physical strength due to excessive turbulence, resulting in coma and "turning white" phenomenon, if not rescued in time, it is very easy to cause the death of fish species. This paper introduces a freehand first aid method with good effect and simple operation. the specific method is as follows: when the fish is found in a coma or whitening, immediately put the fish in the clear water with a water temperature of 10 ℃-20 ℃, which is located in the clear water from the wind to the sun, and water the water frequently, so that the spray can be splashed evenly on the belly of the fish, so that the fish can return to normal. The watering frequency should be close to the respiration frequency of the fish. The fish is moved by the vibration of the water wave, which promotes the blood circulation in the body. At the same time, it cleans the dirt such as the surface and gills of the fish, which is also conducive to the respiration of the fish.
