| dc.description.abstract | Natural mortality for juvenile herring (Norwegian Spring spawners)
is discussed on the basis of following data:
1. Acoustic estimates of the 1975 and 1976 yearclasses of
herring as 0-group and estimates from tagging data of these
yearclasses as 4 year old fish.
2. Acoustic abundance estimates of the 1978 herring yearclass
in Lavangen fjord, Northern Norway.
These data indicate a high natural mortality for juvenile herring. | en_US |
