In the published article, there was an error in Table 1 as published. The corrected Table 1 and its caption “Table 1 Composition of control and experimental yeast feeds (g kg−1) for fish in duplicates. “Vitamin mix” and “Mineral mix” ingredients were provided by NOFIMA (Norway) and “astaxanthin and vitamin mix” ingredients were provided by Aller Aqua A/S (Denmark)” appear below.

In the published article, there was an error in the legend for Table 4 as published. The corrected Table 4 and its caption “Table 4 Growth parameters for fish fed with control feed or experimental yeast-based feed. Data are presented as the mean ± standard deviation. Statistical significance was set at p-value < 0.05” appear below.

Growth parameters for fish fed with control feed or experimental yeast-based feed. Data are presented as the mean ± standard deviation. Statistical significance was set at p-value < 0.05.
Significant results are shown in bold letters. SGR, specific growth rate; CF, condition factor; HSI, hepatosomatic index.
A correction has been made to 2 Materials and methods,2.2 Feeding trial and sample collection.
“Arctic char (n = 126, both genders) over 2 years old were randomly assigned to six 1 m × 1 m water tanks (triplicate tanks per feed with 21 fish per tank) with access to a flow-through system of freshwater (10 L min−1 with a water depth of 20 cm) from Lake Ansjön at Kälarne Aquaculture Center North, Sweden.”
The corrected sentence appears below:
“Arctic char (n = 126, both genders, juveniles) were randomly assigned to six 1 m × 1 m water tanks (triplicate tanks per feed with 21 fish per tank) with access to a flow-through system of freshwater (10 L min−1 with a water depth of 20 cm) from Lake Ansjön at Kälarne Aquaculture Center North, Sweden.”
A correction has been made to 2 Materials and methods,2.2 Feeding trial and sample collection.
“The specific growth rate (SGR) was calculated from day 19 of the trial due to technical problems occurring at the rearing station during the start of the trial.”
A correction has been made to 2.6 Statistics.
“Multivariate data analysis was performed on liver and plasma metabolites using the SIMCA software (version 17; Umetrics, Umeå, Sweden).”
The corrected sentence appears below:
“Multivariate data analysis was performed on liver and plasma metabolites using the SIMCA software (version 17; Umetrics, Suite of Data Analytics Solutions, Sartorius).”
