Table 1 Gut morphology from hindgut sections taken from juvenile Atlantic cod (Gadus morhua) from the CTRL, ULVA, ASCO_N and ASCO_LG groupings at Week 8 and Week 12. Mucosal-fold length (μm) and laminar propria width (μm) measurements are taken from light microscopy images while the microvilli density (AU) measurements are taken from scanning electron microscopy images (± SD). The associated statistical measurements indicated are calculated from Kruskal-Wallis significance testing P < 0.05*, P < 0.01**, P < 0.001***
