Blood samples from healthy adult Atlantic salmon fed an optimal diet in net sea pens were collected at intervals from October to May. Haematological determinations and biochemical serum analyses were carried out on 20 fish in each of seven samples. The ranges of haemato‐logical values for sample means were: haematocrit 44–49%, haemoglobin 8.9–10.4 g 100ml −1 , red blood cell count 0.85–1.10 × 10 12 l −1 , MCV 441–553 × 10 −15 1, MCH 94–106 × 10 −6 g, MCHC 19.4–21.7 g 100ml −1 and leucocrit 0.43–0.96%. The ranges of enzyme activities in serum, for sample means, were: alkaline phosphatase 647–988Ul −1 , aspartate aminotrans‐ferase 202–351 Ul −1 and alanine aminotransferase 4–8 Ul −1 . The ranges of the other parameters analyzed in serum were: total protein 41.6–56.6 gl −1 , albumin 18.3–24.3 gl −1 , albumin/total protein ratio 39.3–44.0%, creatinine 26–46 μmol, triglycerides 2.53–4.98 μmol and cholesterol 9.3–12.8 μmol. These values are considered to be the normal ranges in healthy fish. Variations due to seasonal changes, and the clinical significance of the selected parameters, are discussed. Data showing the reproducibility of the biochemical analyses in serum are presented.
