| Impact Description | In lab experiments, fish consumed more Gammarus fasciatus than Echinogammarus ischnus in dreissenid habitats, which likley allows E. ischnus to out compete other species. It is possible that E. ischnus evades predators more easily than G. fasciatus, particularly on dreissenid covered substrate. |
