Best Treatment Methods for Pond Water Algae Crash and Shrimp Pond Algae Crash, and the Water Color of Algae Crash

During fish farming, spring is an extremely critical period. At this time, temperatures gradually rise again, and combined with continuous rainy weather, algae crash in the water body is very likely to occur, which brings huge economic losses to farmers. So what causes algae crash in fish ponds and shrimp ponds?Algae crashWhat are the reasons? How can it be prevented? Let's take a look together.

1. Causes of algae crash

There are quite a few causes of algae crash. First, sudden temperature changes, continuous high temperatures, rainstorms and other extreme weather will cause water stratification, sudden salinity changes, and low dissolved oxygen in the water body, leading to the death of a large amount of algae. Second, there are difficulties in human management: improper timing of fertilization, insufficient water exchange and insufficient time and amount of water added to the pond, or improper disinfection timing and methods, all can lead to algae death. Third, a lack of nutrient elements leads to a decline in the reproduction rate of algae, the water body gradually ages, and newly grown algae cannot keep up, which may cause the death of a large amount of algae. The water color of an algae crash is very turbid, and you cannot see the bottom. Some also appear green, which is related to the amount of algae that has crashed.

2. Harms of algae crash

A large amount of algae death will reduce the dissolved oxygen level in the water body, and the death of algae will also accelerate the consumption of oxygen in the water, thereby causing fish to suffocate from lack of oxygen. Sufficient algae can absorb ammonia nitrogen and nitrite in the water body. After they die, not only can they no longer absorb them, but they will also decompose and release a large amount of ammonia nitrogen and nitrite, causing fish to die from poisoning. After an algae crash occurs, various indicators of the water body will change, the pH value will decrease, the water body's dead ecological environment will be damaged, the water color will turn red or become clear, and the water body will be turbid.

3. Preventive measures

Daily inspections should be strengthened, and changes in the water body as well as various indicators of water quality should be observed. Weather forecasts should be watched at all times to guard against continuous high temperatures, rainstorms and other extreme weather. When water transparency worsens and it begins to become turbid, this is the prelude to an algae crash. At this time, new water can be added, or water-purifying agents can be used for regulation, combined with bottom-modifying agents for soil improvement, to avoid an algae crash. Aerators can be turned on more often. When water layer separation and insufficient dissolved oxygen occur, they can provide sufficient oxygen supply.

4. Treatment methods (the treatment for algae crash in shrimp ponds is the same)

After an algae crash occurs, not only should attention be paid to detoxification and water regulation, but also to soil improvement. First, use detoxifying agents to splash the whole pond for anti-stress harvesting. At the same time, in order to avoid oxygen deficiency in the water body, turn on aerators more often, and use chemical oxygen-increasing agents such as oxygen boosters to avoid oxygen deficiency in the fish school. When the water source is sufficient, add clean new water and re-cultivate algae.
