The producers who are to give offspring this year have been switched to a pre-spawning maintenance and feeding regime. Nelma is traditionally the first to mature: it is already sorted by gender and placed in special caviar collection units. Spawning will take place using an ecological method — the fish will spawn independently, as in a natural environment, without human intervention.
At the same time, the Tobolsk fish hatchery (the production division of the branch) prepared the base for the new fish breeding season. The storage pond was drained, cleaned, disinfected and refilled; the water supply system and refrigeration equipment, including the ice maker, were checked. In the incubation workshop, the specialists assembled the devices and completed the necessary inventory.
In the next six months, the hatchery will incubate caviar, and the juveniles grown from it will replenish the natural populations of valuable fish species next year.‑The Irtysh basin. This is how the Tyumen branch of VNIRO contributes to the conservation of the biodiversity of Siberian rivers.
