Emergency treatment of crayfish with hypoxia
Excessive density leads to hypoxia: it is necessary to adjust the culture density in time and turn on the aerator to increase oxygen. Hypoxia caused by excessive nutrition: quantitative, qualitative and regular feeding methods should be taken, and the bait should be fed once every morning and afternoon. Shortage caused by excessive area of aquatic plants

Analysis and Countermeasures of hypoxia in cultured Fish
Hypoxia refers to the state in which the internal tissues and cells of fish do not get enough oxygen to maintain their normal function. In order to distinguish from hypoxia in water, it can be called "biological hypoxia" or "tissue hypoxia". Asphyxia (dyspnea) is a phenomenon that occurs during biological hypoxia, and floating head is a common manifestation of dyspnea or asphyxia in aquaculture production. There are two cases of anoxic asphyxia in fish: one is that when the dissolved oxygen in the water is insufficient and the air pressure is too low, even if the respiratory function of the fish is normal, the tissues and cells in the body can not get enough oxygen, resulting in "anaerobic hypoxia";

Emergency treatment of crayfish with hypoxia
In the event of hypoxia in the process of crayfish culture, you can turn on an aerator to increase oxygen in the pond, or sprinkle oxygenator into the pond to carry out first aid. In addition, the solutions to the hypoxia of crayfish are also different for different reasons: 1. The number of lobsters in the water is too dense.

Culture of Monopterus Albus should prevent hypoxia in late Autumn
1. Cool down and increase oxygen. The water temperature is still high in late autumn, which will cause hypoxia in the water body. Can be built on the top of the eel pond, covered with straw shade, can also be planted around the pond vines, such as pumpkins, cucumbers, etc., let the vines climb to the top of the pond to shade, in order to reduce the water temperature. two。 Inject water to increase oxygen. Every

Prevention of fish hypoxia in winter
In winter, fish in ponds need dissolved oxygen to maintain slow respiration although their feeding activity decreases. Dissolved oxygen in ponds comes mainly from phytoplankton photosynthesis and direct dissolution of oxygen in the air into water. However, in the cold winter, once the water surface of the pond freezes, the oxygen in the air cannot be dissolved in the fish pond. When snow covers the ice surface, sunlight cannot directly shine into the pond water, and green plants in the water cannot carry out photosynthesis and produce oxygen. And most fish gather at the bottom of the water in winter,

How to do fish pond hypoxia in winter? How to cure?
In winter, the activity of fish is reduced. Although the oxygen demand is not high, the water surface cannot directly dissolve oxygen in the air due to ice formation in the fish pond. In addition, the oxygen production of plants such as aquatic plants in the water body decreases due to temperature decrease and photosynthesis weakening. It is easy to cause water pollution.

Beware of fish flooding in summer and autumn high temperature season
The phenomenon of fish flooding often occurs in fish ponds due to negligence in management, which has caused great losses to fish farmers. In order to prevent pond fish from flooding, the symptoms, causes and control measures are briefly introduced as follows, which can be used as a reference for fish farmers. 1 symptoms of the disease pond fish floating head due to severe hypoxia, scattered throughout the pond, mouth opened and closed, calmly and directly from the surface of the air to absorb oxygen, serious slowly turn up, struggling to maintain balance, so repeated several times after the abdomen died upward. 2 dead fish species
