Jeonbuk Province released 800,000 masu salmon fry into major rivers within the province to restore the freshwater ecosystem and enhance fishery resources (photo). The Jeonbuk Fisheries Technology Research Institute recently announced that it released 270,000 masu salmon fry into the Mankyung River in Wanju County, 260,000 into the Namdaecheon River in Muju County, and 270,000 into the Dongjin River in Jeongeup City, all of which were produced in-house. The masu salmon fry released this time are healthy seeds that were obtained from mature female fish that matured naturally in June of this year, induced to spawn, and then raised and managed for four months. Masu salmon are known as the cleaners of rivers. In clean water with lots of pebbles and rocks, they remove sediment organic matter, moss, and animal carcasses.
