Silver carp is beautiful in the belly, bighead carp is beautiful in the head, white silver carp has always been a delicious and affordable edible fish species, deeply loved by the people. The price of silver carp is comparable to that of grass carp, and it is relatively stable, and the market demand is large, so it is of great significance to increase the efficiency and production of silver carp. However, parasitic diseases have always been a major obstacle to the normal growth of silver carp, bringing huge losses to farmers.
Parasitic diseases of silver carp such as ringworm, anchorhead gill, Chinese gill and wheelworm disease are common, parasitism not only causes the emaciation of the fish body, affects the feeding and growth rate, reduces the disease resistance of the silver carp, but also damages the gills and tissues of the body, laying hidden dangers for bacterial secondary infections. In addition, because of the outbreak of parasites, frequent use of drugs, water quality fluctuations, silver carp stress, repeated adjustment process, affecting the normal growth of fish.
Although we all know that the use of insecticides to kill insects is risky, which not only affects the growth and breeding of fish, but also destroys the water body to make the water quality worse, often causing fish to eat less, do not eat, slip edges, black bodies, convulsions and even death and other consequences. However, for parasitic diseases, most farmers are still accustomed to waiting until the parasite causes serious diseases before starting to use drugs to kill insects. This kind of thinking is unscientific, since we know that the harm of killing insects is great, why not do a good job of prevention?
Although there are many types of silver carp parasites, most of them are conditionally pathogenic, and the use of scientific and reasonable methods for prevention and control can curb the breeding and reproduction of parasites, reduce the incidence of disease, reduce the incidence of disease, reduce the loss of disease, reduce breeding costs, and improve yield and income.
So how do we prevent parasites?
1. Do a good job in the preliminary treatment: clear the pond through quicklime and other drugs, and kill the base number of insect eggs in the pond silt as much as possible.
2. Improve the immunity of fish body, you can take bile acid and eucommia leaf extract in the feed mixture, promote the detoxification and detoxification of the liver, protect the health of the liver and intestine, maintain the normal function of the liver and intestine, improve autoimmunity and disease resistance, and reduce the probability of pathogenic infection.
3, mixing ingredients lechang for safe deworming, Lechang eucalyptus essential oil is rich in 1,8-eucalyptus, monoterpenes, sesquiterpenes and other natural active ingredients, with antibacterial repellent effect, can act on multiple target cells, for wheel worms, ringworms, anchorhead mackerel, small melon insects, oblique tube worms and other common parasites have a prevention and control effect, use 5-7 days can see obvious effects, and after use does not hurt the fish body, does not affect feeding and growth, does not harm water quality.
Eucalyptus essential oil has been listed in the EU and the United States in the food additive directory, has also entered the EU feed additive certification directory, is a proven green, safe, pollution-free feed additive, in line with the international community's demand for green, non-resistant livestock breeding, and the effect on the prevention of parasites is remarkable, can be used safely and securely in aquaculture.
