Impact

SpreadNotesScore
Spread RateSpread is inevitable within interconnected waterways, spread can be at best deferred between nearby lakes.5
Spread AmountCan spread to low calcium lakes, can tolerate brackish water very well, does not tolerate very cold temperatures so alpine lakes nto susceptible.5
DamageNotesScore
EcologicalHas severely impacted foodchain, natural species of mussels, algae and benthic plants in South America.5
AgriculturalAquaculture impacts and possible restrictions; higher thermal tolerance than other mussels thus anticipated high impact on field irrigation canals.3
Infrastructure5
Culturalimpacts on water and boating recreation; impacts on submerged archeological sites.3
HealthIndirect impacts through potential for toxic algae blooms.1
