Distribution and abundance of Norwegian spring spawning herring larvae on the Norwegian shelf 28 March to 11 April 2007 The objectives of this survey were to map the distribution of herring larvae and other fish larvae on the Norwegian shelf and to collect data on hydrography, nutrients, chlorophyll and zooplankton. Due to the reduced coverage, the larvae index calculated here is not representative for the total larvae abundance, but only for the area from 62oN to 66oN. The index was therefore an underestimate of the larval abundance along the coast. The index, however, was still high and the second highest in the time series going back to 1981.
