  • 1984
    • Active research and propagation of masu and sockeye salmon started.
  • 1994
    • Gene Conservation Section was initiated to study and conserve the genetic diversity of salmon.
  • 1995
    • Genetic stock identification of chum salmon was initiated in the high seas of the North Pacific Ocean to identify the oceanic migration route of Japanese stock.
  • 1997
    • The Hokkaido Salmon Hatchery was reorganized to the National Salmon Resources Center (NASREC).
