The indices are compared to indices previously estimated by the BEAM software. In most years the StoX indices for cod are quite similar to those obtained by BEAM, while they are somewhat higher for haddock. The largest deviations were mainly found for age groups with low indices and/or in years with raising of the indices. Norwegian : Sea2Data programmet StoX er brukt til å estimere akustiske indekser med CV for nordøstarktisk torsk og hyse fra vintertoktet i Barentshavet i 1994 til 2017. Indeksene er sammenlignet med indekser tidligere estimert med programmet BEAM. I de fleste år er StoX indeksene for torsk nokså like BEAM indeksene, mens de er noe høyere for hyse. De største forskjellene var hovedsakelig for aldersgrupper med lave indekser og/eller i år med skalering av indeksene.
