Sander lucioperca is a top predator in introduced habitats (France), i.e., preys on other predators such as pike (Esox lucius) and catfish (Silurus glanis).

A paleolimnologic study in the Danish Lake Skanderborg, where Sander lucioperca was introduced in 1903-04, found evidence of reduced cyprinid population densities. After the introduction of zander, a permanent reduction of cyprinid densities was observed.

In the Turkish Lake Egredir, Sander lucioperca was introduced in 1955 and from 1961 it became an important species in commercial fisheries in the lake. The introduction also had the result that 5 out of 9 indigenous fish species disappeared, among these three species of Phoxinellus, two of which were endemic to Lake Egredir. Consequently, these two species must now be considered extinct worldwide.

In Denmark, Sander lucioperca predation on Atlantic salmon (Salmo salar) smolts was observed in the lower part of the river. This predation had an adverse effect on salmon population dynamics.

A study of zander (Sander lucioperca) diet in French reservoirs found that zander in the smallest size group (< 250 mm length) preyed preferentially on insects and crustaceans. The largest size group (> 330 mm length) fed only on fish and roach (Rutilus rutilus), bream (Abramis brama), and brown trout (Salmo trutta) were observed in their stomach contents.

Experiments addressing zander (Sander lucioperca) diet found that zander preferentially feed on Chaoborus spp. during their planktivorous life stage. When availability is low, zander will also incorporate Daphnia magna in their diet.

Zander (Sander lucioperca), in the Kaniv Reservoir, Ukraine, consumed 21 different food items. The most important prey species were roach (Rutilus rutilus) and perch (Perca fluviatilis), which composed 52.8% and 34.1% respectively. Notably, zander also consumed zebra mussel (Dreissena polymorpha), monkey goby (Neogobius fluviatilis), and round goby (N. melanostomus).

In northern populations, zander diet was mainly composed of roach (Rutilus rutilus), largemouth bass (Micropterus salmoides), and Diptera species. At lower latitudes, common bleak (Alburnus alburnus), red swamp crayfish (Procambarus clarkii), and Atyidae spp. were important prey items.

Experimental introduction of zander (Sander lucioperca) in a Norwegian lake reduced the pelagic refuge available for juvenile roach (Rutilus rutilus) and increased their availability to littoral predators. The effect is an alteration of the fish community towards dominance by littoral predators, perch (Perca fluviatilis) in this study.
