dc.description.abstract | From 1977 onwards an annua1 postlarvae survey has been carried
out off northern Norway in June/July. The aim is to study the
distribution of fish larvae, and to establish an index for thom 53m
to surface. In 1983 the station grid was designed to study mesoscale
features of the larval distribution. It was found that cod
larvae were mainly confined to coastal water masses and haddock
larvae to the Atlantic water masses. The mesoscale circulation
was found to influence the larval distribution. The same
features were also found for the years 1980 and 1981. In 1979
the larval distribution was different, and the reason for this
is discussed. From 64 to 84% of the cod larvae were found in the upper 13 m.
The vertical distribution indicates no die migration, and no
difference of the vertical distribution for the different in
length groups was found, The mean length of the cod larvae was
highest in 1983, indicating good feeding conditions this year.Indications of a high larval mortality from June to September
in 1981 are discussed. The denser station grid introduced in
1983 gives probably a better quantitative index than the
station grid used the previous years. | en |
