Laboratory
|
In lab experiments, Echinogammarus ischnus frequently consumed female Gammarus fasciatus. This predation on adult G. fasciatus was more intense in areas of high conductivity water.

|
Echinogammarus ischnus is generally the superior predator of adult gammarids, but this advantage can be offset by Gammarus fasciatus preying more efficiently on E. ischnus juveniles.

|
In laboratory feeding trials, Gammarus fasciatus was more heavily consumed by yellow perch (Perca flavescens) and northern madtom (Neogobius melanostomus) on dreissenid-covered substrate than Echinogammarus ischnus, while E. ischnus was consumed more heavily on macrophyte. beds
