Regional Impacts

Ecological ImpactHabitat Change
Moderate habitat impacts (Zaiko et al. 2011).
 
Ecological ImpactTrophic Cascade
Moderate ecosystem impacts (Zaiko et al. 2011).
 
Ecological ImpactHerbivory
Rates of feeding and deposition of feces and pseudofeces in the brackish Gulf of Riga were about 1/10 of those of Zebra Mussels in freshwater lakes, so impacts are expected to be smaller (Lauringson et al. 2007). Feeding rates are affected by salinity, windspeed, and chlorophyll concentrations (Oganjan and Lauringson 2014).
