Completion of field work of the Magadan branch of VNIRO to support the 2024 salmon run

 

The work was carried out within the framework of a state assignment, taking into account the strategy for fishing Pacific salmon and char in the Magadan Region in 2024.

 

Ichthyologists monitored producers in the main commercial waterways of the Tauyskaya Bay and Shelikhov Bay, some of which were surveyed in partnership with fishing companies in the Magadan Region. The research included biological analysis, collection of scales and otoliths, assessment of the approaches to the rivers of all types of Pacific salmon, as well as char going to spawn in the rivers of Magadan.

 

During the fishing season, most of the reservoirs of the Magadan Region were surveyed to assess the filling and area of ​​​​spawning grounds of pink salmon and chum salmon. For these works, along with traditional methods of surveying spawning grounds (walking routes, boating, manned aircraft overflights), unmanned aerial vehicles (UAVs) were actively used, which provides significant resource savings with high work results.

 

In the near future, the branch specialists plan to survey hard-to-reach sections of the rivers of the Tauy Bay from the air to assess the filling of spawning grounds of late-stage chum salmon, coho salmon and char.

 

The final stage of the 2024 research will be the processing of the results obtained, the preparation of reports and forecasts for the catch of char and Pacific salmon for the coming periods.
