ABSTRACT. The eggs from 78 Danube salmon females at the age of 5, 6 or 7 years were studied. They were ellipsoidal, but in older females became more spherical. The results revealed that measurement of one egg diameter (minimum or maximum) is sufficient, and that egg size depends on female age, and not on the size (length or weight).
