Marine avian species tend to be faunivores (eg, carnivores, piscivores, zooplanktonivores, molluscivores, and so forth); literature on nutritional or veterinary research involving any faunivorous avian species is sparse, and these studies primarily examine healthy raptors.
They are carnivorous species, mainly piscivores with stenophagy and trophic specialization (Carr & Adams, 1973; Arceo-Carranza et al, 2004; Cocheret de la Moriniere et al.
In the analysis based on piscivore densities, the correlation with the discriminant scores (not shown) was negative for all species that were most abundant in clear lakes (eight species, Table 2) and positive for all species that were most abundant in turbid lakes (12 species, Table 2).
The absence of top-level piscivores preying on age-0 common carp may have led to the denser population in Marsh Lake.
Fishes: 1) herbivores, 2) planktivores, 3) invertivores, 4) omnivores, and 5) piscivores.
Therefore, a quantitative understanding of the foraging ecology of piscivores is needed for ecosystem-based fishery management plans to be successful.
As a top-level piscivore, northern pike may exert substantial influence on a fishery through predation (Anderson and Shupp 1986, DeBates et al.
Piscivore efficiency and refuging prey: the importance of predator search mode.
piscivore and benthic invertebrate consumers) both correlated to Plains Topminnow extirpation.
Studies of piscivore diets and trophic relationships are hereby important for understanding piscivore ecology, and thereby also central for rational fisheries management and conservation biology in freshwater environments (Fortunatova & Popova 1973, Alp et al.
2002) have shown that stratified eutrophic lakes show no reduction in planktivorous species (and subsequent reduction in algal blooms) following piscivore enhancement if phosphorous loading remains high.
