So, the staff of the TINRO noted with satisfaction: all sizes of chum salmon juveniles and Sims was more than expected. This means that the conditions spawning last year was acceptable, and manufacturers – sufficient. And that artificial reproduction of valuable fish also gives the fruit.
Salmon fish hatcheries (hatcheries) operate in all regions of the Far East, where salmon are caught. Many of them are included in the system of the fgbi “Glavrybvod”. The season of release of fingerlings of the first opened this year Paratunsky hatcheries on the Kamchatka Peninsula: April 15, more than 1.5 million pieces of chum salmon fry went free swimming.

It helps us save natural resources and to provide residents with useful products.”
Juvenile chum salmon are produced in the natural environment during may-June is the best time to skate. The large swimming fry put it in the night, protecting from overheating and predators. On Sakhalin and the Kuril Islands in reproduction busy 65 enterprises – more than in any other region of DFO. And they break records: in the year 2019 collected and laid on the incubation of an unprecedented number of eggs of Pacific salmon – 1,177 billion. This season is also expected to release at least a billion fry.
In recent days may have gone swimming fry of pink salmon with Arman hatcheries in Kolyma. In salt water Gorbushina will quickly gain weight in a few years to return to their native river to spawn. “Returns from one to ten percent of fish, – explains the Deputy head of the fgbi Okhotskrybvod Boris Safronenko. – Rolled out of a million fingerlings adults return from ten to one hundred thousand.”
Part Gorbachevoj party paid the company “Avtodormost” – the so-Magadan road reimburse uscheRB caused to the nature of their activities. The cost of compensatory measures are many companies. For example, the shipbuilding complex “Zvezda” in the Primorye region in coordination with the Federal Agency last year provides the production of chum salmon in the river Barabashevka, ryazanovka and Poyma Khasan district. To 2025, should be returned to nature more than 150 million copies of salmon.
