Individual sex hormone profiles in Atlantic salmon can potentially predict maturation later in season

The hormonal events during onset and completion of puberty have been monitored b repeated blood sampling in 100 individually tagged salmon in sea cages and analysis of sex steroids. These results have been compared with gonad histology of sacrificed fish of same origin and indicate the temporal development of recruitment into puberty in one-sea-winter salmon. These results can be a basis for development for hormone masurement kits of on-farm assessment of maturity in salmon.
