Since 1965 the International 0-group fish survey has been carried out
in the Barents Sea during late August and early September. The main
purpose is to determine the year-class strength of some commercial
fish species at an early stage in their life history. The present
contribution is a preliminary study on the growth of the 0-group
during the first half year after spawning. Comparisons of lengths of
cod, haddock, herring and capelin strongly indicate similar variations
from year to year. Since these species inhabit partly the same water
masses the first six months, it is likely that the variation in growth
depends on some common factors. One of these may be the temperature of
the environment. The results so far indicate a relationship between
the growth of larvae and temperature.
