| Impact Description | Studies of zander (Sander lucioperca) in a lake with native perch (Perca fluviatilis) populations indicate an indirect impact on environmental conditions. Zander, through predation, reduces perch abundance. The reduction in perch limits the control on zooplanktivorous cyprinids, leading to altered environmental conditions than would be expected for a eutrophic lake. |
