In a Perch of two pounds the roe weighs seven or eight ounces, and contains, according to Harmers, 281,000 eggs, but according to Picot, nearly a million; the number varying according to the age of the fish. Large and old fishes contain more ova than the smaller ones, which is not surprising, since the individual eggs are of the same size in both; they are very minute, and have been compared to poppy seeds.[2]
