Abstract
The stage of spawning of females of the Arcto-Norwegian cod caught during

peak spawning in Lofoten had a profound effect on several vital parameters of

the eggs and larvae. Significant negative correlations were demonstrated

between stage of spawning and size of eggs and larvae and total content of nonprotein

amino compounds (NPS). Reduced larval activity was recorded in

groups from cod females at the end of spawning. Investigations on the

bacteriological status and the fatty acid profiles of the eggs are also included. The

results are proposed in order to demonstrate a recruitment mechanism and are

discussed in this connection.
