Jokela, J., E. T. Valtonen and M. Lappalainen (1991). Development of glochidia of Anodonta piscinalis and their infection of fish in a small lake in northern Finland. Archiv fur Hydrobiologie. 120:345-355.
The development of glochidia in Anodonta , their seasonal patterns of infection in four fish species and their infection in relation to length and sex of the host individual were studied in a small hyper-eutrophic lake in Northern Finland. Glochidia development took place from June to August and they were fully developed when the water temperature began to fall in autumn. The glochidia were stored in the gill blades to be released in spring. All four fish species, the perch Perca fluviatilis, roach Rutilus rutilus, pike Esox lucius and ruffe Lota lota, were infected in spring. The prevalence of infection of the perch was high throughout the infection period whereas the roach had a high prevalence of infection only at breeding season. The larger roach were infected more often than smaller ones.
