Stress-induced glycosylation changes that differed between sampling time points. Atlantic salmon were grown under low density (LD) and high density (HD) conditions with and without being subjected to an acute stress (AS) protocol and glycans analyzed by LC-MS. The first sampling time point (S1) was 73 days after the Atlantic salmon had been transferred to sea water and the second time point (S2) was 128 days after transfer. (A) Relative abundance of fucosylated structures and (B) Relative abundance of terminal HexNAc structures. (C) Effect of exposure to the acute stress protocol (AS) on HexNAc. To highlight the effect of the AS protocol regardless of fish density and time point, data were normalized to the median of the respective control groups (from panel (B)). Statistics: * p < 0.05, A and B: Kruskal–Wallis test with Dunn’s post hoc test and C: Mann–Whitney U-test. Data are presented as median and interquartile range.
