Salmon! 250 days at mother river (1983)
Every autumn millions of salom return from four years of ocean life to their mother river in Hokkaido, Japan. Nearly all the salmon are captured for artificial cultivation but this film not only shows how this film works but also the natural reproduction behaviour of salmon in a remote river inthe north east of Japan.
