Sustainable yield estimates of the Barents sea capelig stock
(ICES CM Documents;1982/H:45, Working paper, 1982)The Barents Sea capelin suffer mass mortality after spawning. A model is developed to calculate the biomass of springspawners using previous autumn acoustic survey estimates of the total stock as input data. It is assumed ... -

The influence of a stimulated transportation of newly fertilized Atlantic salmon eggs on mortality to the eyed stage
(ICES CM Documents;1985/F:29, Working paper, 1985)Transport of newly fertilized eggs has often resulted in severe mortality of the eggs during incubation to the eyed stage. To investigate the effect of transport on mortality, pooled eggs from several females were handled ... -
Types and frequency of malformations and mortality in eggs of Arcto-Norwegian cod: A field study
(ICES CM Documents;2001/N:12, Working paper, 2001)Embryological studies on living cod eggs in NUNC-trays showed that spontaneous malformations during embryo development are lethal. They are called natural egg mortality in contrast to external lethal factors, as ...
