Their predominant prey is fish and they commonly feed on introduced species such as goldfish, European carp and European perch. When possible, they also eat native fish, with a seeming preference for the perch Leiopotherapon unicolor. However, the Australian pelican seems to be less of a piscivore and more catholic in taste than other pelicans. It regularly feeds on insects and many aquatic crustaceans, especially the common yabby and the shrimps in the genus Macrobrachium.

These opossum shrimps are frequently found in large numbers and filter small food particles out of the water, occasionally consuming larger prey. The diet consists largely of detritus, but water fleas and copepods are also consumed. Opossum shrimps themselves often fall prey to fish. In the Frisian Lakes these include the European perch (Perca fluviatilis), the European smelt (Osmerus eperlanus), the ruffe (Gymnocephalus cernua), young pike-perch (Sander lucioperca) and sometimes the European eel (Anguilla anguilla).

This was important because typical brook fishes had decreased and even disappeared, and had been replaced by the european perch and common roach. As a consequence of the project, the ecological diversity of fish in the Aa had indeed been restored by 2019. Volunteers of Ravon then found 15 species of fish, among these typical brook species like the Common bleak, Stone loach, and Gudgeon. Finding the European Chub, which had been extinct locally, was the final vindication of the project.

The yellow perch (Perca flavescens), commonly referred to as perch, striped perch, American perch or preacher is a freshwater perciform fish native to much of North America. The yellow perch was described in 1814 by Samuel Latham Mitchill from New York. It is closely related, and morphologically similar to the European perch (Perca fluviatilis); and is sometimes considered a subspecies of its European counterpart. Other common names for yellow perch include American perch, coontail, lake perch, raccoon perch, ring-tail perch, ringed perch, and striped perch.

This pelican feeds almost entirely on fish. Preferred prey species can include common carp (Cyprinus carpio), European perch (Perca fluviatilis), common rudd (Scardinius erythropthalmus), eels, catfish (especially silurids during winter), mullet and northern pike (Esox lucius), the latter having measured up to when taken. In the largest remnant colony, located in Greece, the preferred prey is reportedly the native Alburnus belvica. The Dalmatian pelican requires around of fish per day and can take locally abundant smaller fish such as gobies, but usually ignore them in lieu of slightly larger fish.

Due to their ability to crossbreed and their similar morphology, yellow perch are sometimes classified as a subspecies of the European perch. For over 100 years, Canada and the United States have been commercially harvesting yellow perch in the Great Lakes with trapnets, gillnets, and poundnets. In Canada, the estimated catch in 2002 was 3,622 tons with a value of $16.7 million, second only to walleye at $28.2 million. The greatest demand in the United States is in the north-central region, where nearly 70% of all yellow perch sales in the US occur within 80 km (49.7 mi) of the Great Lakes.

Ryvarden (2007): 67 There are eight species of fish in the park: Northern pike and European perch are the most common, others include grayling, common minnow, burbot, three-spined stickleback and the least common, brown trout. The trout came up Pasvikelven about 8000 BC. The other species arrived after the last glacial period from Lake Inari and ultimately from the then fresh-water Baltic Sea.Ryvarden (2007): 64 The bird life is dominated by species from the Siberian taiga, which are otherwise not common in Norway. Species inhabiting the park include Siberian jay, pine grosbeak, Bohemian waxwing, common crane and whooper swan.

Agassiz's perchlet is threatened by predation by non native fish species which have been introduced into its range such as Gambusia holbrooki and the European perch (Perca fluviatilis). There has been degradation of its habitat by the removal of vegetation, logs and snags, rapid fluctuations in water levels caused by river regulation have negatively affected their breeding. An example of this is the failure of the fish to spawn caused by cold water releases from dams. The vegetation they shelter in has been lost due to water regulation and through grazing by the introduced common carp (Cyprinus carpio).

They are the northern pike, roach, stone loach, European perch, and minnow. Rarer native species include the endemic Salvelinus killinensis and the powan, the latter found in only two locations and under threat from introduced ruffe and the Arctic charr. The latter may have been the first fish species to re-enter fresh waters when the last ice age ended, and about 200 populations exist. Atlantic salmon (Salmo salar) The freshwater pearl mussel was once abundant enough to support commercial activities,See for example and Scotland is the remaining European stronghold with about half the global number present. There are populations in more than 50 rivers, mainly in the Highlands, although illegal harvesting has seriously affected their survival.

Catfish of this size is a rarity and, as required by the law, it was returned in to the lake. Other catfishes of this size were reported by the divers in previous years, but they lay lazily on the bottom of the lake, not swimming to the surface. There are 20 to 25 fish species in the lake, including the autochthonous carp, northern pike, zander, common bream, asp and European perch, and the imported, and highly invasive brown bullhead, Prussian carp and pumpkinseed. There are also crayfish and crabs, and since 2010s, the red-eared slider inhabits the lake, too, probably being released in the lake by the owners who kept them as pets.

This parasite "has been recorded from practically every freshwater fish species within its natural range". Food and sport fish and other commercially important species parasitized include carp and minnows such as goldfish and koi, members of the sunfish family, and salmonids such as salmon and trout. Hosts include blue bream (Ballerus ballerus), silver bream (Blicca bjoerkna), European eel (Anguilla anguilla), northern pike (Esox lucius), three-spined stickleback (Gasterosteus aculeatus), pumpkinseed (Lepomis gibbosus), ide (Leuciscus idus), abu mullet (Liza abu), European perch (Perca fluviatilis), common roach (Rutilus rutilus), common rudd (Scardinius erythropthalmus), wels catfish (Silurus glanis), zander (Sander lucioperca), tench (Tinca tinca), and Atlantic horse mackerel (Trachurus trachurus).Boxshall, G. and T. C. Walter. (2013).

Despite its formerly vast size, the Aral Sea had relatively low indigenous biodiversity. Native fish species of the lake included ship sturgeon (Acipenser nudiventris), all three Pseudoscaphirhynchus sturgeon species, Aral trout (Salmo trutta aralensis), northern pike (Esox lucius), ide (Leuciscus idus oxianus), asp (Aspius aspius iblioides), common rudd (Scardinius erythropthalmus), Turkestan barbel (Luciobarbus capito conocephalus), Aral barbel (L. brachycephalus brachycephalus), common bream (Abramis brama orientalis), white-eyed bream (Ballerus sapa aralensis), Danube bleak (Chalcalburnus chalcoides aralensis), ziege (Pelecus cultratus), crucian carp (Carassius carassius gibelio), common carp (Cyprinus carpio aralensis), Wels catfish (Silurus glanis), Ukrainian stickleback (Pungitius platygaster aralensis), zander (Sander lucioperca), European perch (Perca fluviatilis), and Eurasian ruffe (Gymnocephalus cernuus). All these fish aside from the stickleback lived an anadramous or semi-anadromous lifestyle.

The species of fish that are most common in the river are the common roach and the European perch. However, many other species are also found in it, namely the tench, the northern pike, the burbot, the common bleak, the common rudd, the silver bream (also known as the white bream) and the gudgeon. In 2008, a study of the water quality of the Niemica was carried out at its mouth by the Provincial Inspectorate of Environmental Protection (WIOŚ) of Szczecin. The physical and chemical properties of the water were not deemed good and the ecological state of the river was deemed moderate; however, the amount of particularly dangerous substances in the water was good biological properties of the water were described as first-class.

The Donnelly is one of the few catchments left in the state that contains all of the region's endemic freshwater fishes. Native freshwater species include salamanderfish (Lepidogalaxias salamandroides), freshwater cobbler (Tandanus bostocki), western minnow (Galaxias occidentalis), western mud minnow (Galaxiella munda), black-stripe minnow (Galaxiella nigrostriata), western pygmy perch (Nannoperca vittata), Balston's pygmy perch (Nannatherina balstoni), nightfish (Bostockia porosa), and pouched lamprey (Geotria australis). Many estuarine fish are found close to the mouth of the river, these include black bream (Acanthopagrus butcheri), flathead mullet (Mugil cephalus), yellow-eye mullet (Aldrichetta forsteri), Australian herring (Arripis georgianus), and freshwater cobbler (Tandanus bostocki). Several species have been introduced into the river, including eastern mosquitofish (Gambusia holbrooki), European perch (Perca fluviatilis), and rainbow trout (Oncorhynchus mykiss).

Bewick's swans have been spotted on this reservoir. In the winter of 1963 100,000 gulls were counted roosting at the reservoir. As of 2020 Thames Water are reviewing the access arrangements for all three of the Walton reservoirs, The design of the reservoir has an effect on the fish population that can live in the reservoir, the concrete shores means that only European perch and ruffe can breed, except for where there are empty fish cages constructed with netting, which support some plant growth and this allows small numbers of cyprinid fish to breed. The low numbers of fish in the reservoir have led to the zooplankton being dominated by large sized cladocerans and Daphnia and to high growth rates in the few fish that live there.

Scientists for the reserve have recorded 788 species of vascular plants, 77 of moss, and 136 of lichens. With extensive wetlands and forest, the reserve is known for scientific study of insects, of which over 1,500 species have been studied within the borders, and the inventory is far from complete. The animal life of the reserve reflects the richness of the wetlands in particular: 32 species of fish (including Tench, Northern pike, European perch, and Moderlieschen) are found, and 10 species of amphibians (newts, frogs, and toads, including the European fire-bellied toad. The reserves feature a variety of mammals that reflect the different ecozones meeting in the region: brown bear and moose of the European taiga, squirrels, moles and martens of the mixed deciduous forests.

The zander is the largest member of the Percidae and it has a long, muscular body which bears some resemblance to a Northern pike (Esox lucius), hence the alternative English common name of pikeperch. Its upper part of the body is green-brown in colour and this extends onto the sides as dark vertical bars, in a pattern not dissimilar to that of the European perch (Perca fluviatilis) while the lower part of the body is creamy- white. The caudal fin is dark and the pectoral, pelvic and anal fins are paler off-white in colour. The dorsal and caudal fins are marked with rows of black spots on the membranes between the spines and rays, these are largest and most obvious on the first dorsal fin.

The waters of the park are among Sweden's richest, which can be explained by a great number of factors, such as their optimal acidity, a great richness of nutrients, or even, among other things, the zones of rapids alternating with calmer zones. These waters permit the park have not only a great number of species, but also a great number of individual fish and certain fish of enormous size. Among the species present, one can name several species of cyprinids (the family of carp, minnows, barbs, barbels, and others), of which in particular the asp, rare in Sweden.p. 27 The waters abound also with northern pike, with specimens weighing sometimes , with European perch, with zander, and with grayling — which species is classified as endangered in Sweden, much like the brown trout.

The typical fresh-water fish-pond in Norman Ireland would have been stocked with European perch, roach, bream, tench, and pike (regarded as great delicacy), and later with carp. An excellent example of a monastic fishpond, in use since medieval times, is that of the Benedictine Abbey of Kremsmünster in Upper Austria. Unlike other manors, however, the priory of Ballybeg does not appear to have had an enclosure for deer. Like its Bridgetown counterpart, Ballybeg, in which the de Roches also had a part in its foundation and endowment, was probably held from the de Barrys in frankalmoign and included rights such as gallows and baronial courts for all contentious issues and pleas arising on the abbey's domain among its tenants and bondsmen, excepting those reserved to the crown.

In the past, Tivoli Pond was a living place of numerous native fish, like the Danube roach (Rutilus pigus), the tench (Tinca tinca), the European bitterling (Rhodeus amarus), the zander (Sander lucioperca), the European perch (Perca fluviatilis), to the European crayfish (Astacus astacus), to amphibians such as the European tree frog (Hyla arborea), to birds such as the black-crowned night heron (Nycticorax nycticorax), the common moorhen (Gallinula chloropus), and the little bittern (Ixobrychus minutus). The ecosystem was severely hurt by several renovations and the introduction of non-native fish species by fishing clubs as well as by individual visitors. In addition, the red-eared slider (Trachemys scripta elegans) and other pet turtles have been introduced, ousting the native European pond turtle (Emys orbicularis). After the last renovation in 2011, the pond has again become home to non-native as well as native species.

Compared to other parts of the Leningrad Oblast, the winter here is usually milder due to the moderating influence of the Gulf of Finland, but longer. The city of Vyborg and the town of Priozersk are situated on the northwestern part of the isthmus. The Karelian Isthmus is a popular place for hiking, cycling, skiing (Korobitsyno and Kavgolovo), climbing (near Kuznechnoye), canoeing (Losevo), fishing for consumption (of carp bream, northern pike, roach, European perch, ruffe, burbot and others), mushroom hunting (for porcini, red-capped scaber stalk, birch bolete, velvet bolete, slippery Jack, golden chanterelle, Lactarius resimus, woolly milk-cap, ugly milk-cap, saffron milk-cap, Lactarius rufus, various Russulas and others), berry picking (of bilberry, raspberry, woodland strawberry, cowberry, cranberry, cloudberry, bog bilberry and stone bramble). It is a popular summer resort for Saint Petersburg citizens since the late 19th century, served by trains of Finlyandsky Rail Terminal.
