| Abstract |
The reproductive cycle of the freshwater mussel A. cygnea was studied from December 1980 to July 1982. The following conclusions were drawn. 1) Reproductive cycle lasts from July to February and presents two different phasis. 2) During the other part of the year (March, April, May, June) there is a sexual inactivity, but not complete: germinal follicles and gametogenesis are very reduced, ripe gametes are absent. |
