Major illness
Saprolegnia: Freshwater fishes such as grass carp, calyx, whitefish, squid, squid, and bonito are all susceptible groups. When the weather is fine, it can be disinfected with a disinfectant such as salt water, Sheng Sheng An, thioether sand Xing, povidone iodine, and festivals.
Bacterial diseases: enteritis, gills, hemorrhagic disease, erythroderma, white tail disease, etc. Herring, grass carp, calyx, white peony, and salmon are all susceptible groups. Feeding with peptidase stimuli can be fed for 1 week to increase fish immunity and increase the thickness of intestinal mucosa and reduce the incidence of enteritis. If the disease has already occurred, use Changning Mixture, rice bran, wheat bran, etc. to splash feed.
The prevention of bacterial diseases is mainly based on disinfection. Disinfectants such as salt, chlorine dioxide, and festivals can be used for disinfection in early spring.
Trichoderma: The water is turbid and the body is thin and prone to occur. It can be used to regulate water quality through algae paste and Shengshuiling, and it can break down the effect of organic matter and fertilizer water, and solve the problem of muddy water and thin water. Other parasites such as sporeworms, anchorheads, and Chinese sturgeons are rare, but parasites in the intestine, such as maggots, may have multiple occurrences and need to be strengthened.
Water quality
Difficulty in fertilizer and water: Common causes include low water temperature, no algal source, drug residues, excessive horniness, water quality, moss growth, and lack of fertilizer. You need to find out the reasons and then take measures. In general, first use detoxification Ning, use algae paste + Shengshui Lingfei water, low temperature from fat, long-lasting fertilizer effect.
Water quality is turbid: When the temperature rises, the bottom material will cause water quality to fluctuate, which will easily lead to difficulty in fertilizer and water, and outbreak of wheel worms. After the beginning of spring, you can use the Redchip 1 Quanchiposa in advance to consume oxygen-consuming substances to improve the bottom environment, and then use algae paste water.
The water is black: flooding green, flooding the bottom, and excessive amounts of algae in the knee will cause the water to darken. The water caused by the first two causes is dark. You can use the amount of red tablets to increase the amount of splashing in the whole pool. The color of the water is black, and the continuous water changing effect is best.
Crab pond moss breeds: shallow water, large transparency can easily lead to a large number of moss breeding, which in turn can cause difficulties in water and fertilizer. After a large number of mosses die, it is also easy to spoil water quality. It is better to use the algae paste + Shengshuiling in the early stage to make the pond water fat. After the water and fertilizer can inhibit the growth of the moss. If the moss has grown wild, use the drugs that kill the moss first to kill the moss, then use detoxification rather detoxification, algae paste water.
There will be a large number of drug residues after the clear pond, and it is necessary to use the corresponding detoxification products to detoxify them within 3 days in order to make it watery.
