Recently, many owners of farmed yellow jaw fish have reported that seeing "a little red" symptoms on the top of the fish's head can be judged to be "split head disease". What causes that? How can it be prevented? Xiaobian next gives you a share!
Cause of onset
1. There are many residual bait and excrement in the pond, and the water body is seriously polluted
Poor substrate quality, high ammonia nitrogen and nitrite. Dissolved oxygen is low, and fish are in a state of semi-hypoxia for a long time, resulting in the impact of body function, physical fitness and immunity decline.
When the pond water environment is suddenly changed such as inverted algae, turbid water, etc., or encounters sudden changes in the weather, it is very easy to break out of this disease, and a large number of deaths.
2, breeding density is large
Some breeding friends will continue to increase the density of seedlings in order to make money, resulting in less space for fish activities, and mutual crowding during the process of grabbing food is easy to cause wounds on the surface of the body, so that bacteria and parasites can take advantage of it.
3. Lack of awareness of disease prevention
The fact that fish do not become sick does not mean that the fish is healthy, and there is no regular regulation or improvement of water quality and substrate, and internal administration to prevent fish diseases.
Prevention and control measures
1. Maintain a good breeding environment
The use of reasonable stocking density and reasonable feeding system, especially to maintain good water quality, which is fundamental to disease prevention.
2, in the process of breeding, it is necessary to often change the bottom and transfer water
Edwardian bacteria are conditional pathogens, and the harsh water environment will lead to a decline in the immune function of the fish body, allowing bacteria to take advantage of it.
3, good physique is the key
Embroidery should be skillful, protect the liver health of the yellow jaw fish, the liver is good, the fish itself has a good physique, it is not easy to get sick, the physique is good, the food is good, and the vitality is also great!
I hope that the above sharing can help friends who cultivate yellow jaw fish!
