A preliminary morphological and Biochemical study was carried out the North American sturgeon
blood, Polyodon Spathula (Walbaun, 1972), brought to Romania starting with 1992 until1999, for the
Fish Culture Research Development Center, Nucet-Dambovita, situated on the Ilfov Brook, the
Targoviste plane surface. The study was carried out during the years of 1995-1996 and 2007, on 1 and
2 years ald Polyodon Spathula, originated from the USA waters, also on descendents (obtain by
artificial breeding on CCDP-Nucet), reared in ponds on polyculture with cyprinids. The researches
relieved the mean domain of variability for the hematological parameter studies as follows: (Hb)
hemoglobin 3.8 – 9.9 g/dl; (Hct) haematocrit 24.5 – 41.6 %; (RBC) red blood cell count 1.046 – 2.252
x 106/μl; (TSP) total serum proteins 1.24 – 3.7 g/100 ml; and glycemia 7.5 – 19.96 mg/100 ml.
