The aim of the present study was to reveal causes of variation
in carcass traits of farmed Atlantic salmon (Salmo salar). During slaughtering of one year class Atlantic salmon,
composed of half sib and full sib groups, samples for
determination of carotenoid levels in flesh and ovaries were
collected. Also the hepatosomatic and viscerosomatic indexes
as well as relative visceral fat content were determined. As expected it was found that these traits were influenced by
several factors. The material is too limited for firm
conclusions, but evidently the carotenoid level depends largely on stage of maturity and possibly also on genetic factors. Genetic factors seem to influence the visceral fat
content. In hepatosomatic and visceral indexes, and possibly
in visceral fat content, a strange and still unexplained interaction between sex and stage of maturation was observed.
