Abstract

Hematological and biochemical serum analyses were carried out in 131 fish specimens in three age and size groups including smolt, juvenile and breeder. Of these groups, smolt fish were 40 specimens in the average total length range 195.45±12.426mm and had an average weight of 84±15.5g, juvenile fish were 25 individuals and their average total length and weight were 267±20.877mm and 217.20±22.013g, respectively. The 41 breeder fish had an average total length of 578.24±68.487mm and an average weight of 1994.2±775.379g. Another 25 breeder fish were also sampled in the spawning season for blood biochemical analyses had an average total length range of 617±59.9 mm and weighed on average 2227.5±647.5 g each. Red blood cell counts were 866600 per mm3 and 1259400 per mm3 in smolt and breeder fish respectively. The average hematocrit was 48.39% in smolt and 44.29% in breeder fish. The average hemoglobin was 8.85g1d1in smolt and 10.91g/dl in breeder fish. White blood cell count was 8781.58 per mm3 in smolt and 5217.65 per mm3 in breeder fish. Other measurements were as follows: Lymphocyte 90.57% in smolt and 73.22% in breeders, Neutrophil 5.12% in smo1t and 16.92% in breeders, Monocyte 1.27% in smo1t and 4.24% in breeders, and clotting time was 282.34 seconds in smolt and 291.47 seconds in breeder fish. We also measured MCV, MCH and MCHC in smolt and breeder fish along with biochemical parameters. The glucose level was 2.97mmol/l in juvenile and 1.99mmoVl in breeder fish. The cholesterol level was 4.26mmol/I in juvenile and 7.06mmol.l in breeders. The triglyceride amount was 2.35mmol/l in juvenile and 2.47mmol/1 in breeder specimens and the calcium level was 2.44 in juvenile and 2.61 mmol/l in breeder fish.
