The protein concentration of the serum of the Atlantic salmon was measured in samples collected from North‐west England in the years 1967–1975. During this time, the mean protein concentration (g 100ml –1 ) increased from 3.05–7.77 in males and from 1.93–5.72 in females. Whilst a straight line could be fitted to the results, there was the possibility of a three year cycle in the protein concentration. The cycle occurred simultaneously in both males and females. In marine and estuarine fish from Northern Ireland the protein concentration was about twice that in the comparable freshwater group from North‐west England.
