The relationship between egg diameter ( Phi , mm), temperature (T, degree C) and egg development time to hatching (D, in days) was established for approximately spherical, pelagic marine fish eggs as log sub(10)D = 7.10 + 0.608 log sub(10) Phi - 4.09 log sub(10) (T + 26), which explains 82% of the variance of a data set of 140 cases, covering 84 species of teleost fishes, for temperatures from 2.8 to 29.5 degree C and eggs of 0.6 to 3.4 mm diameter. From this relationship it appears that temperature has 4.7 times as much effect on development time asegg diameter when all variables are expressed in standard deviation units. A discussion of these and related factors is given.
