In the Uji River, Japan, a study suggests Limnoperna fortunei served as a first intermediate host for unidentified trematodes of the family Bucephalidae and introduced this parasite into the system. The cyprinid fish Zacco platypus and Squalidus chankaensis were second intermediate hosts while the sheatfish Silurus biwaensis was the final host.

Laboratory

In a mesocosm experiment, cell density, proportion of colonial cells and colony size of Microcystis spp. increased in all enclosures, but these increases were dramatically (and very significantly) higher in enclosures with 100 and, especially, with 300 Limnoperna fortunei, than in the controls. The results indicated that L. fortunei modifies nutrient concentrations and proportions, and promotes aggregation of solitary Microcystis spp. cells into colonies; both these effects can favor blooms of this often noxious cyanobacteria.

Field

Limnoperna fortunei promotes noxious cyanobacteria blooms through modification of nutrient concentrations and the N:P ratio, selective grazing of solitary Microcystis spp. cells over colonial ones, and production of chemical cues that trigger the formation of colonies.

Laboratory
|
Experimental research found that while Limnoperna fortunei accepted single cells of cyanobacteria, filamentous and colonial cyanobacteria were rejected as pseudofeces, a preference that could enhance noxious blooms.

Limnoperna fortunei may also biomagnify contaminants, i.e., the pseudofeces that primarily consist of rejected contaminants are consumed by amphipods.
