<h1 class="pgc-h-arrow-right" data-track="1" what to do if high-temperature cyanobacteria occur frequently > summer? </h1>
In aquaculture, there is a point that needs special attention to the water quality, in the water body with poor water quality, many algae are often grown, and the most likely to grow cyanobacteria in the summer temperature rise is cyanobacteria, so what are the hazards of the emergence of cyanobacteria? First of all, the emergence of cyanobacteria will further reduce the quality of the entire water body, so that the contact area between the water body and the air is reduced, resulting in the death of water generators due to rapid lack of oxygen, and secondly, the death of cyanobacteria will also produce many harmful substances to further endanger the health of aquatic products.
The harm of cyanobacteria
1. Lack of oxygen
First of all, after the outbreak of cyanobacteria, it will form a bloom, floating on the surface of the water like a layer of oil film material, so that the water body can not be effectively in contact with the air, the water body can not be normal dissolved oxygen, and the oxygen content of the water body is reduced. Secondly, when cyanobacteria are in large numbers, they will breathe at night to release a large amount of carbon dioxide, and during the day cyanobacteria will photosynthesize although oxygen will be released, but the water will be affected by the substances it releases pH, in extreme cases the PH value will even rise to 10, which in turn will affect the activity of thiamine enzymes in the fish, under the action of thiaminase, the central nervous system and peripheral nervous system of fish will fail, the excitement will increase, and the rapid movement will further increase oxygen consumption.
2. Algal toxins
Not only the death and decay of cyanobacteria will produce toxic substances, but in the process of cyanobacteria proliferation, a toxic and metabolic substance will be secreted - cyanobacterial algae toxins. The toxicity of cyanobacterial toxins can affect the reproduction of plankton and reduce the quality of water bodies. At the same time, too high concentrations of cyanobacterial toxins can also lead to poisoning in aquatic products, and if they are not controlled, they will even cause direct death of aquatic products.
Third, disrupt the balance
The proliferation of cyanobacteria will also plunder nutrients in the water, and occupy the space for aquatic activities, squeezing the living space of other beneficial algae. Cyanobacteria will have an absolute advantage over other algae after large-scale reproduction, further expand the reproductive range, and the decomposition reaction of cyanobacteria when it dies will also consume a lot of oxygen, and release a large number of toxic substances such as hydroxylamine and hydrogen sulfide. In the case of excessive concentration of such toxic substances and severe lack of oxygen, aquatic organisms will die in large quantities
How to handle it
First, reduce the pH of the water body
The main components of the whole pond are Lactobacillus acidophilus, yeast, actinomycetes, amino acids, active enzymes, small peptides, etc., which can reduce pH and destroy the living environment of cyanobacteria. Inhibits the reproduction of harmful bacteria and cyanobacteria and other harmful organisms, and improves the immunity of the organism of the breeding object.
Second, control algae with bacteria
With Zhongbang Water Cool, the main ingredients are bacilli complex such as dry grass, lichen, natto, etc., active enzymes, etc., which can degrade a large number of algal metabolic toxins, promote the growth of excellent single-celled algae such as diatoms and green algae, and create a good breeding ecological environment.
It is suitable for all kinds of marine and freshwater aquaculture water bodies, especially suitable for aging ponds with more sediment such as silt.
3. Artificial salvage
On the surface of the water with many cyanobacteria, sprinkle flour, gather and fish out. It can effectively alleviate localized water bloom disasters, play a role in exporting nutrients while harvesting algae, and reduce algal toxin pollution caused by death and decomposition of algal bodies. The remaining part is degraded using Zhongbang Detoxification Security.
Fourth, divert water for water exchange
Artificial salvage can only solve the cyanobacteria visible to the naked eye in the water body, for the cyanobacteria has been flooded into the pond, artificial salvage is slightly insufficient, we need to drain the water in the upper layer of the water body, can effectively dilute the concentration of cyanobacteria, and replace the new water so that the toxic concentration and oxygen content to the normal level close, in this environment other algae can also begin to grow, maintaining the dynamic balance of the ecosystem.
Although it is not too late to make up for it, the best time to control cyanobacteria is not after the outbreak, but before the outbreak, that is, how to prevent it, in short, to prevent the water from overweighting as much as possible, to avoid too much fertilizer, animal carcasses entering the pool and so on.
