Common disease prevention and treatment methods for crucian carp: these three conditions cannot be ignored
Many friends who farm aquatic products should encounter some problems, such as diseases or yield, etc. Crucian carp farming is a very widespread project in our country, with a large farming population and large farming scale, and more and more people are entering this industry. As the market continues to expand, farming density has further increased, and it is unavoidable that lawbreakers have begun using antibiotics and other drugs, causing crucian carp to frequently suffer from diseases, and these spread within a short time. So, are you clear about the common disease prevention and treatment methods for crucian carp? Hurry up and learn together!
Common disease prevention and treatment methods for crucian carp
1. Saprolegniasis
This is a relatively common disease of crucian carp. Saprolegniasis is caused by fungi parasitizing the body surface of crucian carp. When the water temperature is 10-15 degrees, fungal spores reproduce easily, and then due to excessive farming density, abrasions on the body surface caused when crucian carp swim or for other reasons, the fungi take the opportunity to attach, germinate and parasitize at the wound site, and gradually spread with reproduction, causing mold to appear on the entire surface of other crucian carp, and finally making the fish swim abnormally, lose appetite, and die from weakening.
Prevention and treatment methods: Because saprolegniasis generally occurs during low-temperature periods, such as spring, everyone can start with farming density, then keep a good record of each disinfection time, and water quality issues cannot be ignored either.
2. Hemorrhagic disease
Hemorrhagic disease mainly occurs in environments where poor water quality management has led to water quality deterioration, and it is especially frequent in highly intensive farming environments. When it occurs, it comes on fiercely, spreads extremely quickly, and has a high mortality rate. This disease is very serious for crucian carp; congestion occurs in every part, and it also appears in the internal organs.
Prevention and treatment methods: Disinfect regularly, inject new water, splash water quality-improving agents, and strengthen water quality management. When the disease occurs, crush 2-3 tablets of Bingduling and mix them into feed for feeding, then feed 1 gram of Xuezhi No. 1 per 5 kg, and it can be cured after one continuous week.
3. Red gill disease
When crucian carp develop red gill disease, it is concentrated in the high-temperature stage, when the water temperature is around 20-26 degrees. When the disease occurs, crucian carp remain motionless 5-10 cm from the water surface. When something is used to strike at them, they will droop, but after a while they will remain motionless as before. In addition, diseased fish are dark and thin, and the gills are congested, red, and swollen.
Prevention and treatment methods: Because red gill disease is mainly caused by water temperature, everyone must pay attention to the daily disinfection issue. Regulate water temperature and water quality well, and the carbohydrate in the feed must not exceed 40%. After the disease occurs, strontium perchlorate can be splashed on the pond to treat it.
That is all that Tuliu.com has summarized today about common disease prevention and treatment issues in crucian carp. When farming crucian carp now, as long as the cause is identified, it is actually relatively easy to diagnose and treat.
