The research ship of the Federal Agency for Fishery “Professor Kaganovsky” February 17 went to the port of Vancouver and took on board a group of scientists from Canada, USA, Japan and the Republic of Korea to perform unique international marine research of Pacific salmon in the open waters of the North Pacific. On the same day, the NIS set off for the flight
For the first time, integrated trawl surveys will be conducted in the Gulf of Alaska, where a significant portion of the populations of this species of fish traditionally winter. The expedition takes place in the framework of the International Year of Salmon and is of great importance for fishing for one of the most popular species of aquatic biological resources on the world market.
Studies will improve the accuracy of forecasts of salmon approaches to spawning sites and recommendations on the volume of industrial catch. The fact is that the survival rate of salmon in the ocean in winter is one of the main factors for the success of the fishing season, which takes place in the summer-autumn period. It is estimated that 20–40% of the total number of salmon survive during the wintering season. But so far this period has remained the least studied.
Filming will last until mid-March. After this, the ship “Professor Kaganovsky” will return the foreign crew to Vancouver and will go to conduct research of bottom and deep-water species of aquatic biological resources in the area of the Imperial Ridge.
The opening of the International Year of Salmon was held in St. Petersburg in September 2018 at the II International Fishery Forum. The total world catch of Pacific salmon after a decline in the 1950–1970s to 400 thousand tons has now grown to 1 million tons. Pacific salmon are the second largest fishery target of Russian Far Eastern fishermen after pollock. Since the beginning of the 2000s, their mining is at a high level. In 2018, over 676 thousand tons of Pacific salmon were caught in the Far East of Russia – a record volume in the entire history of observations.
In the framework of the International Year of Salmon, surveys are also planned in the exclusive economic zone of the Russian Federation. In 2019, it is planned to increase the number of studies and conduct 28 “salmon” trips.
