During the gametogenic cycle of Mytilus, we observed atresic phenomena in gametes at different cycle stages. Gametes are degraded both within the follicle and throughout the gonoduct. This degradation shows two consecutive phases: lysis of cytoplasmatic structures and membranes, more evident in oocytes; and haemocytic digestion of lisated material. Environmental factors clearly influence this phenomenon. Atresia is intense in winter, decreases during spring, and rises again at the end of the gonadal cycle. In winter, it is related to overmaturation of gametes due to unfavourable conditions for stimulating spawning (low temperatures and lack of food availability). In summer, the high temperatures trigger the end of gametogenic cycle, and tot...
