Sammendrag
Genetic analyses have been performed on samples of spawning cod
(March) , a large number of eggs and yalk sac 1arvae (May,
postlarvae (July) and O-group cod (August-September). The
distribution of eggs and larvae at different stages as well as
biological and genetic data were in accordance with earlier
observations on larval drift from the main spawning graunds,
Same samples drawn from localities on the coact or in fjords
differed , however, significantly from samples in the open sea.
The genetic analyses of these samples, as observed in analyses
of the LBH-3 locus, confirm the existence of 1ocally spawning
groups of coaslial cod. The genetic data are discussed in
relation to stock structure of cod, the significance of genetic
variation within stocks and the problem of concervation of
genetic resources.
