The breeding season starts in early summer, when female mussels transport their eggs from the gonads to special breeding chambers within their gills called marsupia. Fertilization takes place within the marsupia after male mussels from further upstream have released their sperm into the water.
Glochidia were prepared for infestation by rupturing marsupia and disassociating glochidial masses into a container of clean aquarium water.
littoralis, as in other unionids, oogonia turned into early vitellogenic oocytes, which subsequently grew within follicles, formed vitellogenic oocytes, entered late vitellogenesis, underwent maturation, and finally were ovulated into marsupia. During these phases the changes were similar to those previously reported for other unionids (Grande et al., 2001; Park and Chung, 2004; Cek and Sereflisan, 2006; Sereflisan et al., 2009a).

The relationship between the length of females and the number of eggs and mancae was determined by simple regression analysis [34], utilizing 80 individuals of each stage, selected randomly among those with intact marsupia.

imbecillis does not depend on parasitism (It carries the young in its marsupia during metamorphosis from glochidia to juvenile mussels, thus eliminating the parasitic stage on fishes which other species undergo) and it is hermaphroditic.
