En automne, les algues commencent a disparaitre progressivement. En effet, le poids maximum des thalles est atteint en Juillet (No. 40g). Pendant la meme periode, la longueur des algues atteint son maximum (25,3 cm). Quand au diametre de la fronde, son evolution au cours du temps n'est pas claire. La biomass de Cystoclonium atteint egalement son apogee en Juillet (environ 35 g de MS/m2)Study of Cystoclonium purpureum showed that thalli begin to grow in spring and reach highest developement in summer. In autumn, these algae disappear gradually. In fact, the maximum weight is obtained in July (No.40g). In the same period, algae length reach its maximum value, too (25,3cm).
