The effects of maternal status of Arcto-Norwegian cod on egg quality and vitality of early larvae. 2. Preliminary results of the experiment in 1992
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...
