Effect of seawater pH on selected blood biochemical parameters of juvenile turbot Scophthalmus maximus (Linnaeus, 1758)
The effect of seawater pH on blood physiology in juvenile turbot Scophthalmus maximus (Linnaeus, 1758) reared in recirculating aquaculture systems (RAS) was examined. S. maximus (19.89±0.25 g) were exposed to six pH levels at 6.3±0.2, 6.8±0.2, 7.3±0.2, 7.8±0.2, 8.3±0.2 and 8.8±0.2. Haemoglobin conte...
