Differentiation and control of cyanobacteria, green algae and moss
Recently, the weather is hot, and many aquaculture farmers come to consult, saying that the surface of their fish ponds is green, and they don't know whether it is cyanobacteria, green algae or moss. The rapid reproduction will soon cover the surface of fish ponds, which will easily lead to thin water quality and lack of oxygen, which is not good for fish growth. This is a headache for farmers. Below, Baitaifu Aquatic Products teaches you to distinguish and prevent cyanobacteria, green algae and moss.

1, cyanobacteria

In essence, cyanobacteria are prokaryotes, also called cyanobacteria; Most blue-green algae have a gelatinous shell outside their cell walls, so they are also called myxomycetes. Among all algae, cyanobacteria is the simplest and most primitive one. Cyanobacteria is a unicellular organism, which has no nucleus, but the center of the cell contains nuclear substances, usually granular or reticulate, and chromatin and pigment are evenly distributed in the cytoplasm. This nuclear substance has no nuclear membrane and nucleoli, but it has nuclear function, so it is called prokaryote (or quasi-nucleus). There is also a kind of circular DNA- plasmid in cyanobacteria, which plays the role of carrier in genetic engineering. Cyanobacteria, like bacteria, belong to "prokaryotes".

Baitaifu Aquatic Products suggested using blue quiver decomposing enzyme to kill cyanobacteria. Generally, cyanobacteria will produce some toxins after death. At this time, we need some detoxification products, such as holy water, Jieduling pond and algae poison, otherwise it will easily cause algae poisoning. Pay attention to observe the dissolved oxygen in water after use to prevent hypoxia.

2. Green algae

The cells of green algae plants are similar to those of higher plants, and also have nuclei and chloroplasts, which have similar pigments, storage nutrients and cell wall components. Chlorophyll A and B are the most common pigments, as well as lutein and carotene, so they are green. The stored nutrients are mainly starch and oil. There are one or several starch nuclei in chloroplasts. Cell walls are mainly composed of cellulose. Swimming cells have 2 or 4 terminal tail flagella of equal length.

Green algae is beneficial algae, but it is not good in excess, which easily leads to poor water quality. Once it grows wildly, it will quickly pollute the water quality. Therefore, Baitaifu Aquatic Products suggests using compound Bacillus to help you purify water, stabilize water quality, efficiently and rapidly decompose aging algae, residual bait, feces and other organic substances in water, and promote the growth of excellent unicellular algae. Obviously inhibit the reproduction of harmful algae such as cyanobacteria and dinoflagellate, and maintain the balance of algae phase.

3.moss

Bryophyte is an aquatic bryophyte, which is a eukaryote with nucleus, membrane, nucleoli and various organelles. Moss is a common disgusting algae in aquaculture. Moss is a general term for filamentous algae in some green algae in freshwater algae plants by farmers. In aquaculture ponds, some filamentous algae float on the water surface, some grow at the bottom of the pond, and some are stuck at the bottom of the pond and stand upright in the water, so these mosses are also called epiphytic filamentous plants, floating filamentous plants and aquatic filamentous plants.

Moss-killing and mite-killing agent can completely kill moss mud skin, harmful algae and harmful microorganisms, and has no toxicity and residue. The water depth per mu is 1 m, and 30ml is used per mu, so a bottle can be used for about 3 mu, and a proper amount of moss is poured in dense places. This product is non-toxic and has no side effects, and has no influence on aquatic plants and aquatic fish.
