There are many benefits to sunning ponds in winter
The author recently visited Xingyang rural areas in our province and found that many fishermen friends quickly disinfected the fish pond after selling out the commercial fish, and then put the fish species in proportion. They think that this will enable fish species to adapt to the pond environment early so that they can open their mouths and grow early in spring. In fact, it is better to expose fish ponds, especially aged fish ponds, to butterflies in winter. The aging of fish ponds is aggravated by the accumulation of fertilizer feed residues, fish feces and sediment impurities, which directly affects the aging of fish ponds in the next year.

Will the crayfish die in the sun pond?
Crayfish don't die in the pond. Moreover, the process of sunbathing can increase the oxidation capacity of the sludge at the bottom of the pond, reduce the content of organic matter so as to reduce the oxygen consumption in the future culture process, and at the same time kill a large number of bacteria and bacteria in the sludge.

What should be paid attention to in the construction of eel ponds on the roof?
What should be paid attention to in the construction of eel ponds on the roof? Considering the bearing capacity of the roof, it is suggested that all the roof ponds should be built with bricks (the wall thickness is 6 cm); except for the breeding ponds, soilless culture should be adopted. From the point of view of cooling, a wall often illuminated by the sun should be raised to exceed the height of the culture pond, and then about 10 cm should be retreated to begin to build the pool, so as to prevent the sun shining on the pool wall for a long time, causing the water temperature of the pool to rise abnormally than that of other ponds, causing the imperceptible high temperature of the pool water and causing Monopterus Albus to die.

Methods of preventing fish from anoxia in winter
In winter, although the intake of fish in the pond decreases, they still need a certain amount of dissolved oxygen to maintain slow breathing. The dissolved oxygen in the pond mainly comes from the photosynthesis of phytoplankton and the oxygen in the air dissolves directly into the water. However, in the cold winter, once the surface of the pond freezes, the oxygen in the air cannot dissolve in the fish pond. When heavy snow covers the ice, the sun cannot shine directly into the pond water, and the green plants in the water cannot carry out photosynthesis to produce oxygen. And most of the fish gather at the bottom in winter, if the water quality is poor,

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.
