The invention discloses a culture method for sturgeon in flowing water. A formula for an artificial feed comprises the following components in percentages: 45% of fish meal, 15% of feed yeast, 15% ofbean cakes, 5% of maize meal, 5% of dry milk, 3% of mixed salt, 2% of amino acid, 2% of an adhesive and 5% of an attractant. According to the invention, a correct sturgeon culturing method creates a good living environment for the sturgeon, and the quality of water is guaranteed; bait and sturgeon feces in the interior of a pool are timely cleaned; and a scientific formula of the artificial feed provides good feeding bait for the growth of the sturgeon. Diseases and pests are prevented, and different measures are taken for different diseases during occurrence of diseases and insect pests, wherein (1) enteritis disease is treated mainly through antibiotics, (2) saprolegniasis is treated through an immersion bath of a table salt solution with a concentration of 0.05% for 20 min, and (3) ichthyophthiriasis is treated through soaking in a formaldehyde solution with a concentration of 0.05% for 30 to 60 min. Good survival of the sturgeon is guaranteed, and healthy culturing of the sturgeonis promoted. An EM bacterial liquid is used, so the quality of the water can be remained to be clarified; the quality of the water is prevented from aging; the growth of plankton is promoted; and diseases of the sturgeon are prevented from occurrence.

The invention belongs to the technical field of aquaculture disease prevention and treatment, and particularly relates to a technical method for preventing and treating ichthyophthiriasis of culturedfishes by using artificial flow generation and ozone. A relatively closed circulating water culture system is constructed and comprises a breeding area, a sewage collection area and an ozone treatmentarea, wherein water flow with a specific flow speed is manufactured in the breeding area through a water pushing and flow making device; fish bodies are washed through the habit that fish like to push water, ichthyophthirius multifiliis larvae in water are difficult to adhere to the surfaces of the fish bodies, and meanwhile ichthyophthirius multifiliis falling off from diseased fish bodies and sediments containing ichthyophthirius multifiliis at the bottom of a pond are scoured to the sewage collection area. After the water flow enters the ozone treatment area, the ichthyophthirius multifiliis larvae are killed through ozone with a specific concentration, the water body subjected to ozone treatment is pushed to the breeding area again through flow making equipment, the steps are repeated, the density of the ichthyophthirius multifiliis in the water body is continuously reduced, and therefore the purpose of preventing and treating ichthyophthiriasis is achieved. By adopting artificialflow making and ozone pest killing technologies, the technical method has the advantages of greenness and environmental friendliness.
