Reappearance of Norwegian spring spawning herring on spawning grounds south of 60°N

In spring 1989 herring spawned west of Karmøy (near Haugesund) on the\nNorwegian west coast. Prior to 1945 the coastal areas around Haugesund\nwere among the most important spawning (and fishing) grounds of the\nNorwegian spring spawning herring, but since 1959 there has been no\nreports of spawning herring in that area. This paper gives an account\nof the recordings in 1989, and of the length and age distributions of\nthe herring. Possible migration routes are also discussed.
