Abstract – Bryozoans are sessile fi lter feeding organisms able to play an important role in the cycling of organic matter in freshwater ecosystems. However, the quality and quantity of food particles ingested by bryozoans are still not well-known. Therefore, an experimental design was performed in order to investigate the clearance rate (CR), food selection and ef fi ciency of assimilation by the freshwater bryozoan species Plumatella geimermassardi. P. geimermassardi was collected from the Col fi orito Marsh (Umbrian Natural Park, Italy), during summer. A higher grazing rate of suspended and dissolved solids was evidenced in the colonies collected in June, July, than in August. Food selection and assimilation of phytoplankton were determined. The algal species ingested as diet food item and those excreted with the faecal pellets were taxonomically identi fi ed. The results provide new information on CR and food selection by P. geimermassardi and enhance knowledge on its biology. Insights on feeding preferences by bryozoan species can provide valid information about their feasible distribution and abundance.

Les bryozoaires sont des organismes fi ltreurs sessiles capables de jouer un rôle important dans le cycle de la matière organique dans les écosystèmes d'eau douce. Cependant, la qualité et la quantité de particules alimentaires ingérées par les bryozoaires ne sont pas encore connues. Par conséquent, un plan expérimental a été réalisé a fi n d'étudier le taux de clairance, la sélection des aliments et l'ef fi cacité de l'assimilation par l'espèce de bryozoaire d'eau douce Plumatella geimermassardi . P . geimermassardi a été récoltée dans le marais de Col fi orito (Parc naturel ombrien, Italie), pendant l'été. Le taux de broutage des solides en suspension et dissous a été plus élevé dans les colonies collectées en juin, juillet, qu'en août. La sélection des aliments et l'assimilation du phytoplancton ont été déterminées. Les espèces d'algues ingérées comme aliments et celles excrétées avec les granules fécaux ont été identi fi ées taxonomiquement. Les résultats fournissent de nouvelles informations sur le taux de clairance et la sélection des aliments par P . geimermassardi et améliorent les connaissances sur sa biologie. Les observations sur les préférences alimentaires des espèces de bryozoaires peuvent fournir des informations valides sur leur répartition probable et leur abondance.

In aquatic environments mass of DOM is higher than that of organisms ( Thomas, 1997 ). In boreal surface waters DOM consists mostly of humic substances (refractory organic matter), while the remnant part is mainly composed by carbohydrates, amino acids, low molecular weight organic and fatty acids (labile fraction). The inorganic fraction of dissolved solids is mineral salts. Suspended organic material includes phytoplankton and biotic debris, while inorganic suspended solids are represented by clay, sand, silt, volcanic ash, silica, aluminumoxides,iron,calcium carbonate andparticulatematter of anthropogenic origin ( Thomas, 1997 ).
