Box 1870, N-5024 Bergen, Norway A study of first-feeding herring (Clupea harengus L.) larvae during the period 1985-1993 [Elektronische Daten] [Petter Fossum] Since 1987, the spawning stock of Norwegian spring-spawning (Nss) herring has increased from 0.5 to 2.5 million metric tonnes with recruitment of the 1983 year class to the spawning stock. During the same period the increase in herring larval production, resulting from an increase in the spawning stock biomass, has been followed by surveys on the Norwegian shelf in March and April. The purpose of the present study was to investigate whether the number of larvae can be related to spawning stock biomass and to look for density-dependent effects on gut-contents and larval growth. The strong signal from the 5-fold increase in spawning stock biomass was easily seen in the increased abundance of herring larvae since 1988. No density-dependent compensatory mechanisms related to growth were observed; however, a depensatory increase in dry weight was connected to the high abundance of post yolk sac larvae. This must be related to large scale spatial and temporal changes in prey abundance. Co-occurrence of herring larvae and their prey (match) could also be recognized in the early stages by the increased abundance of larvae beyond the yolk sac stage. © 1996 International council for the Exploration of the Sea Articles nationallicence herring larvae nationallicence first-feeding nationallicence spawning stock nationallicence ICES Journal of Marine Science Oxford University Press 53/1(1996-02), 51-59 1054-3139 53:1<51 1996 53 icesjms https://doi.org/10.1006/jmsc.1996.0005 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1006/jmsc.1996.0005 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Fossum Petter Institute of Marine Research, P.O.
