In 2024, specialists conducted the final scientific and experimental cultivation of the pelnel hybrid (peled and nelma) in lakes in the south of the Tyumen region. Compared with pelchir (peled and broad whitefish), a hybrid popular with commercial farms, pelnel showed a 48% increase in weight. And under favorable hydrological conditions, the growth advantage becomes even more significant. Compared with the low-water year of 2023, the average pelnel weight in 2024 increased by 10%, and the pelchir hybrid by 2.5%.
Scientists from the Tyumen branch of VNIRO have calculated that the use of the pelnel hybrid in pasture aquaculture will increase the yield of commercial fish by 1.5 times, and the industrial return by 2.7 times compared to the use of peled as a farming object.
Western Siberia and the southern Urals are rich in lakes that are potentially suitable for pasture farming of whitefish. It is their interspecific crossing that will intensify pasture fish farming and industrial aquaculture. Today, this resource is used only partially; the pelchir hybrid is mainly grown on an industrial scale.
Growing hybrid forms with a higher growth rate, increased ecological plasticity and survivability allows for more efficient use of the bioproduction capabilities of reservoirs and an increase in the production of commercial fish products.
In 2025, scientists from the Tyumen branch of VNIRO will continue the experimental cultivation of other hybrid forms of whitefish.
