A short history of the Downs stock of herring

Abstract

The data on the Downs stock of herring were re-examined and the year-classes during the early part of the Second World War were low because of the stock recruitment relationship. This was near linear. There was a positive correlation between Pseudo/Para, the preferred food of the larval herring, when the quantity of Pseudo/Para was declining. However, the decline in Pseudo/Para did not affect the stock recruitment relationship.
