How to deal with algae in fish pond water? The best treatment method of algae in shrimp ponds what color is the water

In the process of fish culture, spring is a very critical period, when the temperature gradually rises, coupled with continuous rainy weather, the phenomenon of algae falling in water is very easy to occur, which will bring huge economic losses to farmers. So what is the reason for algae dumping in fish ponds and shrimp ponds? How to prevent it? Let's take a look.

1. The reason of falling algae.

There are many reasons for falling algae, one is the sudden change of temperature, continuous high temperature, torrential rain and other extreme weather, which will lead to stratification of water body, sudden change of salinity and low dissolved oxygen, resulting in the death of a large number of algae; second, the difficulty of artificial management, improper timing of fertilization, pond water exchange and insufficient time and water quantity, or improper disinfection time and methods will lead to algae death. Third, the lack of nutrient elements leads to the decline of the reproduction rate of algae, the gradual aging of the water body, the inability of new algae to keep up, and the opportunity to cause the death of a large number of algae. The color of algae water is very muddy, can not see the bottom, some will also be called green state, which is also related to the number of algae.

2. The harm of falling algae.

The death of a large number of algae will reduce the dissolved oxygen of the water, and the death of algae will also accelerate the digestion of oxygen in the water, resulting in anoxic asphyxia of fish. Sufficient algae can absorb ammonia nitrogen and nitrite in water, not only can not be absorbed after death, but also decompose and release a large amount of ammonia nitrogen and nitrite, which will lead to fish poisoning. After the occurrence of algae fall, various indexes of the water will change, the pH value will decrease, the ecological environment of the water will be destroyed, the color of the water will become red and the fire will become clear, and the water will be turbid.

3. Preventive measures

It is necessary to strengthen daily inspection, along with the observation of water body changes and various indicators of water quality. Always observe the weather forecast and beware of continuous high temperature, torrential rain and other extreme weather. When the transparency of the water body becomes worse and begins to become turbid, there is a prelude to algae falling. At this time, new water can be injected, or water purification agents can be used to adjust, and geological improvements can be carried out with bottom reagents to avoid algae falling. Can open more aerator, when there is water layer separation and insufficient dissolved oxygen, it can provide sufficient oxygen supply.

4. Treatment method (same principle for algae treatment in shrimp ponds)

After the occurrence of algae dumping, attention should be paid not only to detoxification and water transfer, but also to geological improvement. first, the detoxification agent should be sprinkled in the whole pool for anti-stress hurdle, and at the same time, in order to avoid lack of oxygen in the water body, open more oxygen boosters and cooperate with chemical oxygen enhancers such as oxygen, to avoid fish hypoxia. In the case of sufficient water, the technology is injected with clean new life, and the algae are re-cultivated.

The above is the introduction of the reasons and prevention methods of algae fall in fish ponds. I hope I can help you. If you want to know more about it, please follow us.
