Causes of diseases during and after wintering

Freshwater fish fulminant hemorrhagic disease, also known as bacterial sepsis, is one of the most serious infectious diseases affecting farmed fish. The disease has an acute onset, many species of fish, a large age range, a wide epidemic area, a long epidemic season, and a high mortality rate, which is likely to cause serious losses to the freshwater aquaculture industry.

Each station of the Photosynthetic Science Beneficial Agricultural Service Center provides high-quality water quality testing services for the majority of breeding friends all year round, mainly including some common aquaculture water indicators, such as ammonia nitrogen, nitrite, pH value, dissolved oxygen, salinity, residual chlorine, etc. , and some special water indicators detection, such as heavy metals, alkalinity, hardness, etc., and can accurately locate the biological species, biomass and biological development trend of aquaculture water. The company is guided by Professor Lei Yanzhi, a well-known expert in water chemistry, and Professor Li Yonghan, a well-known expert in aquatic biology. Our service personnel are proficient in water index detection and aquatic organism judgment technology, and can provide breeding friends based on the results obtained. We propose correct, effective and practical solutions to help farmers and friends get rich and escort the aquatic industry!
