Sammendrag
More than 30 years of Russian and Norwegian data on spring-spawning herring larvae along
the coast of Norway has been investigated and analyzed together with different environmental
parameters and spawning stock size. Quantifiable relations between time series of the yearly
abundance of herring larvae, the spawning stock and wind has been found. Together with
information on the sea temperature this form the basis for predicting 3 years ahead the
strength of the 3 years old herring stock with a preliminary accuracy of about +3*109
individuals.
