Description
Summary:Precision and relevance of pre-recruit studies for fishery management related to fish stocks in the Barents Sea and adjacent waters. Proceeding of the sixth IMR-PINRO Symposium Bergen, 14-17 June 1994 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.
