How to Deal with Dinoflagellates? A Detailed Guide to Dinoflagellate Treatment Plans in Aquaculture Water
Dinoflagellates are a type of single-celled assemblage with two flagella. Their shapes include spherical, filamentous amorphous, and amoeboid forms, and after dinoflagellates die they can produce dinoflagellate toxin that causes fish death. Below, the editor will bring you treatment plans for dinoflagellates.
I. Treatment plans for dinoflagellates
Disinfection is an important measure to prevent dinoflagellate reproduction. Splash copper sulfate over the whole pond so that the pond water contains 0.7 grams of the chemical per cubic meter. Apply more heavily in the downwind area. After 1-2 days, appropriately add new water to improve water quality; when they multiply in large numbers, use the method of adding a large amount of new water and scattering lime to inhibit their reproductive growth; if the dinoflagellates still do not die, use Kelzaoling or Xinlü 50 for local splashing to kill them.
II. The harm of dinoflagellates
Dinoflagellates are the general name for a large group of flagellate algae, with oval bodies. When they multiply in large numbers, they can often change the color of the water body in which they live. Some dinoflagellates can serve as feed for certain aquatic larvae, but some groups among them can produce multiple toxins during reproduction, causing nerve numbness, metabolic disorders, and respiratory obstruction in fish, ultimately leading to death. Oodinium can also attach to fish and live as a parasite, absorbing nutrients from the fish body and stimulating the fish to proliferate mucus, making the fish body look as if it is coated with a layer of rice flour, hence it is called “powder disease”. The prevention and control of dinoflagellates is the same as that of blue-green algae.
Dinoflagellates have a relatively large impact on fishery aquaculture, but as long as attention is mainly paid to prevention and basic management work such as maintaining hygiene in the aquaculture pond, it can be avoided.
