Reference intervals for haematological and plasma biochemical parameters in sobaity seabream juveniles (Sparidentex hasta, Valenciennes 1830)

Sobaity sea bream (Sparidentex hasta) is distributed in the Western Indian Ocean, Persian Gulf, and Oman Sea. For monitoring health status in this species in aquaculture condition, standard reference values for haematological and plasma biochemical parameters are indispensable. Heparinized blood samples were collected from 143 healthy sobaity seabream juveniles raised in cylindrical polyethylene tanks with filtered running seawater. Haematologic reference intervals were as follows: RBC count 1.67–2.2 × 106 µ/L , total WBC count 8.8–14.5 × 103 µ/L, lymphocytes 85–96%, neutrophils 2–6%, haemoglobin 28–60 g/L, Hct 24.5–33.8%, MCV 126.3–191.7 fL, MCH 14.4–26.5 pg, MCHC 92–180 g/L, ESR 1.5–5 mm/h and RBC:WBC ratio 119.2–207.5. Plasma chemistry reference intervals were as follows: total protein 3.2–3.9 g/dL, albumin 0.3–0.58 g/dL, globulin 2.7–3.4 g/dL, alkaline phosphatase 444–866 U/L, alanine aminotransferase 239–506.5 U/L , lipase 95.5–120 U/L , amylase 4–8 U/L , sodium 173–211 mmol/L, chloride 103–136.5 mmol/L, potassium 2.7–4.4 mmol/L, calcium 2.6–3.1 mmol/L, inorganic phosphorus 2.9–5.3 mmol/L, osmolality 430–503 mOsm/Kg, glucose 6.16–7.88 mmol/L, cholesterol 4.07–7.7 mmol/L, triglyceride 2.22–3.91 mmol/L, HDL 1.36–2.44 mmol/L, LDL 0.84–1.19 mmol/L and VLDL 0.27–0.78 mmol/L. Values reported here will be useful for evaluating the health status, interpretation and better understanding of various disease signs in sobaity seabream juveniles.
