METHOD FOR CULTURING RAINBOW WRASS LABRUS BERGYLTA Russian patent published in 2022 - IPC A01K61/10 

FIELD: fishery.

SUBSTANCE: from the captured wild producers that have undergone sanitary treatment, a broodstock is formed, which is adapted to artificial conditions for one to two years in pools with sea water with a salinity of 33-34‰ and a temperature of 6-13°C, with an illumination of 50-600 lux, with oxygen content 7.5-8 mg/l^-1, stocking density 5 kg/m³-19 kg/m³ and fed with commercial feed. For spawning, spawners aged 6-9 years who have reached puberty are used, offering food 1 time in 3 days until saturation, and spawned eggs are transferred to incubation pools with filtered sea water, in which the temperature is maintained at 10-15°C, salinity - 33 -34‰, photoperiod - complete darkness, oxygen level 6-9 mg/l^-1, water flow - 3 l/min. At the end of the hatching period and within 50 days of growing to a viable stage for larvae in the pools, the temperature is maintained at 10-10.6°C, salinity - 33-34‰, light regime 5-50 lux, or 18 hours - natural light, 6 hours - complete darkness, oxygen 9.1-9.9 mg/l^-1, stocking density of larvae - 4-50 pcs/l, feeding regimen - 5-8 times a day, using for feeding larvae from 4-5 to 20 days rotifers, 20-27 days - rotifers and Artemia nauplii, 27-50 days - Artemia nauplii, maintaining the density of rotifers 5-7 pcs/ml, the density of brine shrimp nauplii - 1 pc/ml.

EFFECT: invention provides obtaining viable offspring of rainbow wrasse.
