Analysis of the literature on pelagic fish eggs enabled generalizations to be made of their energy densities, because the property of being buoyant in sea water appears to constrain the proximate composition of the eggs and thus to minimize interspecific variation. An energy density of 1.34 J μl −1 of total egg volume is derived for most species spawning eggs without visible oil globules. The energy density of eggs with oil globules is predicted by x (J μ1 1 ) where x is the fractional volume of the oil globule.
