Small clean waters breeding method for litopenaeus vannamei
A technology for prawns vannamei and prawns, which is applied to the field of clear water cultivation of prawns in small water bodies, can solve the problems of affecting the quality of shrimp fry and shrimp farming products, affecting the success rate of farming, and immunity to shrimp fry diseases, etc. The effect of reducing disease or immunity decline, easy operation, and reducing water pollution

Embodiment 1
[0016] 1) Put high-quality and healthy Litopenaeus vannamei nauplii into a circular aquarium with a size of 1 cubic meter at a density of 150,000 larvae per cubic meter of water. The seawater used in the aquarium is pre-treated by sand filtration, ozone and ultraviolet disinfection, and then filtered through filter membranes with pore sizes of 10, 1.0, and 0.5 μm in sequence.
[0017] 2) Add Chaetoceros and yeast when the prawn larvae develop to the sixth stage, so that the density of Chaetoceros is constant at 10,000 cell / mL, and the density of yeast is constant at 0.25g / m 3 .
[0018] 3) When the prawn larvae develop to the first stage of zoan larvae (Z1), add chaetoceros to a density of 50,000 cells / mL, add algae for 12 hours, and then press 0.25 g / m 3 The ratio is added to the yeast. Observe with a microscope every 4 hours, calculate the number of algae, keep the density of algae at 50,000 cells / mL, and at the same time, keep the density of yeast at 0.25g / m 3 .

Embodiment 2
[0024] 1) Put high-quality and healthy Litopenaeus vannamei nauplii into a circular aquarium with a size of 1 cubic meter at a density of 200,000 larvae per cubic water body. The seawater used in the aquarium is pre-treated by sand filtration, ozone and ultraviolet disinfection, and then filtered through filter membranes with pore sizes of 10, 1.0, and 0.5 μm in sequence.
[0025] 2) When the larvae develop to the 6th stage larvae, add Sclerotinia and yeast, so that the density of Sclerostenae is constant at 10,000 cell / mL, and the density of yeast is constant at 0.25g / m 3 .
[0026] 3) When the prawn larvae develop to the first stage of zoan larvae (Z1), add Sclerotinia to a density of 45,000 cells / mL, add algae for 12 hours, and then press 0.25g / m 3 The ratio is added to the yeast. Observe with a microscope every 6 hours, calculate the number of algae, keep the density of algae at 45,000 cells / mL, and at the same time, keep the density of yeast at 0.25g / m 3 .

Embodiment 3
[0032] 1) Put high-quality and healthy Litopenaeus vannamei nauplii into a circular aquarium with a size of 1 cubic meter at a density of 180,000 larvae per cubic water body. The seawater used in the aquarium is pre-treated by sand filtration, ozone and ultraviolet disinfection, and then filtered through filter membranes with pore sizes of 10, 1.0, and 0.5 μm in sequence.
[0033] 2) When the prawn larvae developed to the 6th stage larvae, add Trichophytes and yeast, so that the density of Sclerostenae was constant at 10,000 cell / mL, and the density of yeast was constant at 0.25 g / m3.
[0034] 3) When the prawn larvae have developed to the first stage of zoan larvae (Z1), add Sclerostenae to a density of 50,000 cells / mL, add algae for 12 hours, and then add yeast at a rate of 0.25 g / m3. Observe with a microscope every 5 hours, calculate the number of algae, keep the density of algae at 50,000 cells / mL, and at the same time, keep the density of yeast at 0.25g / m3.
