The feeding ecology of three piscivorous fish species (perch (Perca fluviatilis), pike (Esox lucius) and burbot (Lota lota)), was studied in the subarctic Pasvik watercourse (69 ° N), northern Norway and Russia. All three species primarily occupied the benthic habitats in the watercourse. Perch and burbot exhibited distinct ontogenetic niche shifts in food resource use, perch changing from a dominance of zooplankton to zoobenthos to fish, and burbot from zoobenthos to fish. Fish prey dominated… Expand

Feeding ecology of piscivorous brown trout (Salmo trutta L.) in a subarctic watercourse
TLDR
The prey selection of brown trout was, to a large extent, explained by the differences in density and size-structure of coregonids in the two sampling areas. Expand
Predation by brown trout (Salmo trutta) along a diversifying prey community gradient
TLDR
Five lakes of a subarctic watershed are contrasted to explore how prey community characteristics affect prey selection and growth rate of the common top predator, brown trout, and the selection of small-sized, pelagic prey fish appeared to be a favourable foraging strategy for the brown trout. Expand
Diet Partitioning in a Diverse Centrarchid Assemblage in the Atchafalaya River Basin, Louisiana
TLDR
Trophic and habitat resource partitioning among seven centrarchid species inhabiting four macrohabitat types in the Atchafalaya River basin (ARB), a 900-km2 bottomland hardwood swamp in south-central Louisiana, revealed substantial diet overlap among three predominately insectivorous species. Expand
Interactions between invading benthivorous fish and native whitefish in subarctic lakes
TLDR
It is predicted that increased fish diversity and density would deplete the invertebrate community and increase resource competition between native and invasive species, and the findings indicate that trophic specialisations of invasive species play a key role in determining their impacts on the systems they invade. Expand
Ontogenetic diet profiles and size-dependent diet partitioning of ruffe Gymnocephalus cernuus, perch Perca fluviatilis and pumpkinseed Lepomis gibbosus in Lake Balaton
TLDR
Life-long diet ontogeny and size-dependent intra- and interspecific diet partitioning of the native ruffe and perch and the introduced pumpkinseed, suggest that in Lake Balaton these three species effectively partition food resources throughout their life span. Expand
Ontogenetic Dietary Shifts in a Predatory Freshwater Fish Species: The Brown Trout as an Example of a Dynamic Fish Species
The brown trout (Salmo trutta) is a species of Eurasian origin, but at has become naturalized in many other parts of the world. It has an outstanding socio-economic importance, both in commercial andExpand
Preference for Cannibalism and Ontogenetic Constraints in Competitive Ability of Piscivorous Top Predators
TLDR
It is suggested that the observed selectivity for cannibal prey over interspecific prey and the competitive advantage of prey species over juvenile piscivores are common features in fish communities and that the observation has the potential to mediate coexistence in size structured intraguild predation systems. Expand
Differential interactions of two introduced piscivorous salmonids with a native cyprinid in lentic systems: implications for conservation of roundtail chub.
TLDR
Habitat use patterns indicate that roundtails chub are more susceptible to predation by brown trout than by lake trout because both roundtail chub and brown trout occupy the littoral zone for a prolonged period. Expand
Feeding habits and ontogenetic diet shifts of Bombay duck, Harpadon nehereus
TLDR
As Bombay duck size increased, fish prey increased in importance, whereas euphausiids and decapods decreased in importance. Expand
Feeding biology of pike, Esox lucius L., 1758 inhabiting Lake Ladik, Turkey
TLDR
It was determined that there were significant positive relationships between prey dimensions-predators size and predator mouth sizes-predator length and the pike exhibited a specialist feeding strategy on fish. Expand

TLDR
Analysis of the piscivore guild in fish species-rich lake and stream systems in eastern Ontario showed the co-occurrence of three types: specialists that became piscvorous at the age of a few weeks, ‘secondary’ pISCivores that are fish-eaters only later in life and species in which fish consumption is limited to taking some larvae. Expand
Growth, morphological variation and ontogenetic niche shifts in perch (Perca fluviatilis) in relation to resource availability
TLDR
It is suggested that the key factors affecting size-specific growth and body morphology of perch in the system studied are the availability of resources in the benthivorous and piscivorous niches. Expand
The population dynamics of pike, Esox lucius, and perch, Perca fluviatilis, in a simple predator-prey system
TLDR
The pike, and particularly the perch populations, have features characteristic of fish communities in unperturbed ecosystems: namely, a wide range of age classes, stability in biomass with variation dampened by longevity, and low production. Expand
Trophic ecology of largemouth bass and northern pike in allopatric and sympatric assemblages in northern boreal lakes
TLDR
The seasonal food habits of allopatric and sympatric assem­ blages of largemouth bass and northern pike in six interior lakes within Voyageurs National Park, Minnesota are investigated. Expand
Feeding Flexibility in Northern Pike (Esox lucius): Fish versus Invertebrate Prey
TLDR
Although northern pike are widely considered to be top aquatic piscivores, it is found that the frequency of occurrence of invertebrates was high, at least on a seasonal basis, in some systems. Expand
Ecological Correlates of Feeding Flexibility in Northern Pike (Esox lucius)
TLDR
The summer diet and habitat use of northern pike in a small lake where potential fish prey were limited to one other species is described, it is suggested that the observed dietary change was not related to variation in habitat use, but rather to a change in the abundance of prey in the littoral zone.

Food and Feeding Relations of Eurasian Perch (Perca fluviatilis) and Pikeperch (Stizostedion lucioperca) in Various Waters of the USSR
Eurasian perch, Perca fluviatilis, and pikeperch, Stizostedion lucioperca, are the most widely distributed of the 11 species of percids in the USSR. This literature review examines their feedingExpand
Species-specific antipredator capacities and prey refuges: interactions between piscivorous perch (Perca fluviatilis) and juvenile perch and roach (Rutilus rutilus)
TLDR
The results suggest that juvenile roach had an overall higher capacity to avoid predation than juvenile perch, however, in the presence of qualitatively different prey refuges Juvenile perch responded to predators with more flexible refuge use than juvenile roaches. Expand
The ontogeny of piscivory and its ecological consequences
TLDR
Focusing on interspecific variation, it was found that species that were born larger and had larger mouth gapes became piscivorous at younger ages and at smaller sizes, and maximum and mean prey size eaten increased with predator size in all species. Expand
Effects of prey species composition and habitat structure on foraging by two functionally distinct piscivores
TLDR
Compared foraging by two piscivores, pike and zander, on two prey fishes, crucian carp and rudd, in the presence and absence of artificial vegetation in a field enclosure experiment, it was found that pike had a higher predation rate than zander inThe presence of vegetation, whereas zander had aHigher predation rates in the absence of vegetation.
