Randomized trial investigates artificial reproduction outcomes in Hucho taimen, suggesting effective fish farming techniques.

The aim is to develop techniques for artificial reproduction and aquaculture of Hucho taimen in the Yenisei basin.
Conducted artificial reproduction in the Bakhta River from May-July 2025.
Used male taimen aged 6-7 years and females aged 10-11 years for breeding.
Developed a technique for caviar production using anesthesia and released fish back to their habitat.
Ovulation occurred at water temperatures of 7.9 °C with a reduced water level.
Produced and released approximately 6,000 taimen larvae into the Bakhta River after controlled incubation and feeding.
Caviar incubation lasted 209-245 degree days at temperatures of 7.6-14.2 °C.

Zadelenov et al. (2026) studied this question.
