Molecular Characterization and Expression of α-Globin and β-Globin Genes in the Euryhaline Flounder (Platichthys flesus)

Table 2

Plasma (a) and blood (b) composition of flounder chronically adapted to SW or FW.

(a) Plasma composition.

	SW	FW
Osmolality (mosmo/kgH2O)	302.62 ± 3.32	285.2 ± 3.35**
Mg^2+ (mmol/liter)	4.7 ± 0.18	2.8 ± 0.35**
Cl^− (mmol/liter)	141.4 ± 1.65	124.4 ± 2.21**
Ca^2+ (free) (mmol/liter)	1.77 ± 0.027	1.8 ± 0.039
Na^+ (mmol/liter)	151.48 ± 2.39	146.92 ± 2.38
K^+ (mmol/liter)	2.7 ± 0.038	2.74 ± 0.13

(b) Blood composition.

	SW	FW
Hematocrit (Hct) %	25.82 ± 1.3	29.78 ± 1.7
RBC × 10^12/L	2.258 ± 0.1	2.562 ± 0.2
Hgb g/L	74.4 ± 3.6	84.2 ± 5.4

Independent samples t-test was used to assess differences between chronically adapted FW and SW flounder and between experimental and time matched controls at each time point, *𝑃<0.05, **𝑃<0.005  (𝑛=7).
