Post-hatch size at the A) alevin stage as the percentage of dry body tissue mass relative to total yolk and body dry mass of alevins 5 days post hatch (n = 16 per treatment except chronic normoxia [n = 15] and chronic warm hypoxia [n = 13]) and B) fry stage as Fulton’s condition factor (n = 47 per treatment except late hypoxia and late warm hypoxia [n = 45], early hypoxia and chronic warming [n = 46] and early warming and early warm hypoxia [n = 48]). Boxplots of the data represent the median as the centre line, IQR as the box, values 1.5 times the IQR as the whiskers and values greater than 1.5 times the IQR as black points. Diamonds indicate the mean value. Colours represent the developmental treatment: control (green, 100% DO, 10°C), hypoxia (blue, 50% DO, 10°C), warm (red, 100% DO, 14°C) or warm hypoxia (purple, 50% DO, 14°C). The three boxplots within each stressor type represent the developmental timing of exposure as early (eyed stage, light colour shade), late (silver-eyed stage, medium colour shade) and chronic (fertilization through hatching, dark colour shade). Letters indicate significant differences among treatments (P < 0.05).
