METHOD OF PASTURING CULTIVATION AND CULTURING OF BRINE SHRIMP Russian patent published in 2017 - IPC A01K61/00 

FIELD: agriculture.

SUBSTANCE: in the method, from natural reservoir-recipient with mineralization of 30-350 g/l, water and soil are taken. Further, eggs, 30-40% in dry form, the rest in soil moistened with ground, nauplii and adult brine shrimp crustaceans are transported in water tanks. Water from the reservoir-recipient is gradually added to reservoirs in an amount of 30-50% of the total volume and the soil in an amount of 30-50% of the total volume from the reservoir-recipient. Brine shrimp is populated in the reservoir-recipient, the populating is made by adult crustaceans 15-25%, nauplii 15-25%, and eggs 50-70%. Moreover, 60-70% of eggs scatter on the surface of the littoral sections of reservoir with a density of 20000-40000 pcs/m², the rest of eggs is covered with bottom sediments to a depth of 2-4 cm in the coastal zone of reservoir. In the method, the ground is taken from the natural reservoir-recipient, the size of soil fraction is selected, in which the high germination of brine shrimp eggs is noted. Further, a container is filled with soil of this fraction, brine shrimp eggs are introduced into it and the container is buried on the bottom of a natural reservoir-recipient or placed on the shore and fills 20-30% of the water from the recipient reservoir and 70-80% from the brine shrimp reservoir. After hatching nauplii and the development of the crustacean, brine shrimp is released into the reservoir-recipient. In the method, reservoir-recipient with an area of 0.01-10 hectares is equipped and filled with water to 0.15-2 m. At a distance of 0.5-1.5 m from reservoir-recipient a perforated container, with a hole size of 0.5-3 mm, is penetrated, which is filled with soil taken from sites with reservoirs in which the brine shrimp population is present, salt and eggs of brine shrimp are added to the soil in the calculation of 0.8-1.2 g on 1 kg of soil.

EFFECT: methods allow to naturalize brine shrimp in reservoir that acclimatizes with natural reproduction, allow to obtain both embryonic forms of brine shrimp and adult crustaceans, and eggs at all stages of brine shrimp life cycle.
