Prediction of aquaculture diseases in Ningxia in October 2021
By: Date: 2021-10-03 Categories: industrynews Tags: ,

In October, entering the late autumn season, the fish load in the pond reached the highest in the whole year. With the decrease of temperature, the temperature difference between day and night is large, and the vertical exchange of water layer is frequent, which is easy to lead to the mutation of algal phase and anoxic flooding. When harvesting and fishing, each farm should pay attention to gentle operation in the links of net pulling, sorting, fish disinfection and transportation, so as to avoid secondary infection caused by mechanical damage to the fish. Pay attention to the drug off period before aquatic products are listed to ensure that listed aquatic products comply with relevant national food safety regulations. Prohibit the use of all kinds of prohibited drugs to ensure quality and safety.

According to the prediction of the freshwater aquaculture meteorological service center, the average temperature in Hubei Province in October is 16.9 ~ 17.3 ℃, which is 0.1 ~ 0.5 ℃ lower than that of the whole year. October has entered autumn, and the cultivated varieties began to enter the final growth stage before overwintering. The temperature fluctuates frequently, and the temperature difference between morning and evening is large. Aquaculture diseases are still mainly bacterial diseases and parasitic diseases. In aquaculture production, attention should be paid to regulating water quality and strengthening feeding management.

Forecast and forecast of aquaculture diseases in Xinjiang Uygur Autonomous Region in April 2021
By: Date: 2021-03-27 Categories: foodtechnology Tags: ,

Since April, the weather in Xinjiang has gradually warmed up. After the overwintering period of the farmed fishes, their physique is weak, and the nets and ponds are easily damaged. After the overwintering period, the aquaculture water body tends to age and the water environment becomes worse. The disease inducers such as viruses, bacteria, and parasites in the water body become active as the water temperature rises, and the susceptibility to disease gradually appears in the spring. The forecast of Xinjiang’s aquaculture disease in April 2021 is now as follows.

Prediction and forecast of aquaculture diseases in Ningxia in April 2021
By: Date: 2021-03-24 Categories: foodtechnology Tags: ,

This year, Ningxia’s spring temperature rebounded rapidly, and the wintering period was shorter than in previous years, but the daily temperature difference fluctuated greatly. In April, the aquaculture industry in Ningxia entered a new round of aquaculture production cycle. The nutrients accumulated in the body of the aquaculture fish after the overwintering period consume a lot of nutrients, and their physical fitness is relatively weak. At the same time, after the overwintering period, the aquaculture water body tends to age, the water environment becomes worse, and the disease inducers such as viruses, germs, and parasites in the water body become active, and the susceptibility to disease gradually appears in the spring.
