Sammendrag
Hatching and distribution of first feeding larvae of Norwegian spring

spawning herring have been monitored on the Norwegian shelf in March

and April since 1985. During this period the spawning stock increased from

0.5 to 2.0 mill. metric tonns with the recruitment of the 1983 yearclass to the

spawning stock. This was seen as a significant increase in the number of

larvae over the spawning beds since 1988. During the same period the

recruitment of herring changed dramatically, with low to moderate

recruitment in the period 1985-1988 and good recruitment in 1989-1992.

Samples of first feeding herring larvae were taken within the central area of

herring larvae distibution. Length, weight and gut content were measured.

Plots of length versus dry weight are presented together with results from

gut content analyses. The importance of these parameters as an early

indication of recruitment is discussed.
