Many ponds where California bass are farmed in late autumn and early winter are particularly prone to outbreaks of inmitigma, especially in some extreme weather conditions. The water temperature suitable for the propagation of oblique tube worms is about 12-18 degrees, but the breeding environment deteriorates, the resistance of the fish body is poor, and it can also multiply in large quantities at high temperatures, and the inclinated tube worm can live in the water body for 1-2 days after leaving the fish body, and as long as there is a chance, it will be transferred to other fish bodies or water bodies.
Oblique tube worm mainly infected with the Gills and body surface of the California seabass, the symptoms are not obvious when a small amount of parasitism, a large number of parasitism will cause the Surface of the California Perch, the gills produce a large amount of mucus, resulting in serious damage to the gills of the California sea bass, causing secondary infection of bacteria, the emergence of symptoms such as dragging mud, making the California perch breathing difficult, swimming slowly, not feeding, causing a large number of deaths in a short period of time.
Now there is no special drug for the treatment of intracula, so it is very important to do a good job in the prevention of intubats, and now immediately enter the overwintering period of California perch, intracula will not disappear with the decrease of temperature, but will be temporarily hidden, and when the temperature rises again, causing a large number of deaths of California perch, seriously endangering the survival rate of California perch, so before the Overwintering of California perch, it is necessary to do a good job in the prevention and control of intubats, and solve the hidden bombs in advance.
Measures to control oblique tubeworms
1, improve the pond water environment, once there is too much organic matter in the water body, it is very conducive to the growth and reproduction of oblique tube worms. Therefore, regular use of Qingqing to improve the environment at the bottom of the pond, decompose a large amount of residual bait and feces at the bottom of the pond, degrade ammonia nitrogen, prevent the formation of nitrite, and enhance the self-purification ability of the pond. Do a good job of dissolved oxygen management at the bottom of the pond to reduce the incidence of common parasites such as inclined tubeworms.
2, regular use of safe and harmless insect repellent products Che Jing / Hundred Grass Repellent Net for prevention and control, Che Jing / Hundred Grass Repellent Net is extracted from plantain, purslane, acacia flower, Wumei and other traditional Chinese medicine extracts, regular mixing can effectively prevent and control freshwater fish oblique tube worms, spores, wheel worms, ringworms and other parasites, try to avoid or reduce the use of toxic insecticides with side effects in the breeding process, to ensure the normal feeding and growth of fish.
