Recently, all parts of the country are cooling, the water temperature at this stage is also relatively low, the lower the water temperature, the more rampant the small melon worms, resulting in a high incidence of California perch small melon insects, have your California perch been recruited? Today Xiaobian will give you an analysis!
In the breeding industry, it has always been said: "Once the fish is infected with small melon worms, it is basically not saved." This is because so far there is no drug that can solve the problem of small melon worm disease. Without a specific drug, can we just sit still? No! Knowing oneself and knowing the other can win every battle, let's first see what the little melon worm likes?
Influencing factors
1, small melon worms like low temperature, the lower the water temperature, the more small melon worms flooded, the faster the infection rate.
2, small melon insects like water body organic matter, the worse the water quality of the substrate, the more organic matter, the more small melon insects.
3, small melon worms like to bully soft and afraid of hard, the worse the physique, especially the wounded fish are more likely to be infected. Small melon worm is difficult to treat or even can not be treated, through the above content also understand what the small melon worm likes, want California perch not infected with small melon worms, in advance to do a good job of prevention is the key!
Prevention and control measures
1. Increase the water temperature of aquaculture water bodies
The suitable water temperature for the propagation of small melon insects is 15 to 25 °C, and the prevention can be carried out by appropriately reducing the water level to increase the water temperature in late autumn, early winter and early spring under pond culture conditions.
2. After the small melon insect is infected, it must be prevented from infection and protect a large group
Small melon insects are seriously infected, tissue and organ damage is serious, it is difficult to treat with drugs, we must learn to prevent large groups, reduce healthy fish infection.
3. Cultivate fertilizer water quality
The occurrence of small melon worm disease is closely related to the water quality of the pond, and it is generally easy to cause melon worm disease in the pond with thin water quality, so it is appropriate to cultivate water quality in the current small melon insect epidemic season.
4. Do a good job in daily health care
(1) The physiological condition of sea bass is directly related to the occurrence of small melon worm disease, and the low immunity of the body of sea bass is more susceptible to the invasion of small melon worms. Therefore, in the epidemic season of small melon worm disease, the physique of the sea bass should be strengthened, and liver protection products such as bile acid should be taken in the mixture to protect the liver of the sea bass and improve the immunity of the sea bass.
(2) At present, it is the period of rapid reproduction of parasites such as small melon insects, and it is prevented in advance with essential oil repellent products, and then combined with health care products that improve physical fitness, reduce stress problems during seasonal changes, and improve the immunity of fish.
In aquaculture, diseases should still be based on prevention, do a good job in daily health care, reduce the occurrence of diseases, and smoothly increase production and income!
