The authors report the distribution of cholesterol in the ripe, unspawned eggs of 10 spp of teleost (carps, catfish and murrels) together with values for egg diam. The egg, with its relatively abundant yolk, is shown to be fairly rich in cholesterol, though values differ from sp to sp. The lowest value (700 mg/100 g) was recorded from Wallago attu, and the highest (1537 mg/100g) from Heteropneustes fossilis. In general the levels are lowest in carp eggs. No definite relationship could be established between lipid and cholesterol contents, or between egg diam and total cholesterol. The role of cholesterol in physiology of fish is discussed; it is noted that the carnivorous fish tended to have higher levels of cholesterol in their eggs.
