<Anchor> In the
fall of each year, full-sized salmon returns to the east coast river, and the return rate is only one for every 200.
However, for the first time in Korea, we succeeded in raising young salmon as mother salmon in a tank.
It seems to be of great help not only for salmon farming, but also for related industries.
This is reporter Cho Jae-geun.

Large fish swim in the tank.
These are salmon that have been raised since last spring by hatching the eggs of salmon that returned to Namdaecheon in Yangyang, Gangwon-do.
Thirty three-year-old salmon are swimming in the tank right next to it.
Young salmon, which was 5 cm long, was grown only in a tank into adult salmon, 50 cm or so.
This is an achievement after many trials and errors in the process of adjusting the water temperature and adapting young salmon hatched in freshwater to seawater.
Two grown-ups received eggs and gave them artificial insemination.
[Kim Joo-kyung/ Deputy Director of Donghae Life Resource Center, Korea Fisheries Resources Corporation: The amount of eggs is a little smaller because (breeding salmon) is smaller in size and weight than returning salmon.
However, since the egg's ecology and size are normal, there will be no big crowds to hatch and produce even fry (I think.)]
Success in raising salmon on land led to a green light on salmon resource expansion.
When young salmon is released into the river, it travels 18,000 kilometers to the North Pacific Ocean and returns to its hometown in 3-4 years, with a return rate of less than 0.5%.
On the other hand, raising salmon as a mother makes it easier to stock more fry to increase the number of returning salmon.
[Kim Doo-ho/Director of Donghae Life Resource Center, Korea Fisheries Resources Corporation: If we stably supply mothers through breeding, it will help to increase salmon resources.] A
new opportunity for salmon farming will also be provided, so there are few places in related industries such as food and bio. It is not expected to be helpful.
