dc.description.abstract | An echo survey for 0-group sprat was carried out in October
-November 1974 in fjords of western Norway. Charts of
sprat distribution are presented together with indices of abundance
calculated from mean echo integrator reading per
nautical mile and area of each fjord system. The indices reflect
the year class strength, and as the fishery is based on the one
year old sprat, a clear relationship is found between indices
determined in autumn and catch the following year. This is
demonstrated by data from the echo survey in 1973 and catch in 1974. | en |
