rearing of fresh-water shrimp. SUBSTANCE: method involves growing larvae by simultaneously keeping shrimp and zooplankton larvae in water medium; providing conditions for adaptation of postlarvae to fresh water and additionally growing larvae in nursery reservoirs to obtain planting material. In the process of growing of larvae, egg mixture is added into water medium. Egg mixture particle size and zooplankton density in water medium are selected in accordance with stage of development and size of larvae. In the process of additional growing of post larvae for obtaining planting material, sortings and reduction of density of planting are regularly performed depending upon age of larvae. EFFECT: increased efficiency in producing full-value planting material with increased size and improved shrimp survival rate. 4 cl, 1 tbl |
