This study summarizes fecundity, gonad index of the most common and abundant echinoderm species (Paracentrotus lividus) of the Aegean Sea (western Turkey). Paracentrotus lividus was collected monthly at coast of Cesme for six months and biometric parameters were measured and then dissected. Indices of gonad were calculated. The mean number of eggs were determined and eggs diameter were measured. Mean egg diameter was 91,14±1,46 μm. There was a peak in fecundity in March (346.582 eggs/female) that correlated with the observed peak in gonad indices (11.02±0.54 %) and egg size (95.68±01.98 μm). Larger eggs corresponded to more eggs per unit body weight.
