A Piscivore is a carnivorous animal which lives on eating fish. This tigers sharp teeth and strong jaws are the classical physical traits expected from carnivorous mammalian predators A carnivore (IPA: ), meaning meat eater (Latin carne meaning flesh and vorare meaning to devour), is an animal that eats a diet consisting mainly of meat, whether it comes from live animals... A giant grouper at the Georgia Aquarium Fish are aquatic vertebrates that are typically cold-blooded; covered with scales, and equipped with two sets of paired fins and several unpaired fins. ...
Some animals, like the walrus, are not completely piscivores, while others, like the Aquatic Genet, are strictly dependent on fish for food. The name piscivore is derived from the latin word "Piscis" which is fish. Binomial name Odobenus rosmarus (Linnaeus, 1758) Subspecies Walruses are large semi-aquatic mammals that live in the cold Arctic seas of the Northern Hemisphere. ...

The favourable effect of macrophytes on the recruitment of piscivorous perch is shown by the increasing size of perch during the plant expansion in the lake.
Once a fish assemblage with piscivorous perch and pike is established, this favours the maintenance of abundant submersed macrophytes as the piscivores keep in check the zooplankton-feeding and bottom-feeding cyprinids (Scheffer, 1990).
(1995) pointed out that the potential indirect effect of piscivores reducing the predation pressure upon grazing zooplankton through behavioural changes of zooplanktivores may be an important mechanism in enhancing the stability of submersed macrophytes in shallow lakes.
All early piscivores were hatched early in the summer, but many early-hatched members of the 1994 cohort did not shift to piscivory in their first summer of life.
The life history characteristics and trophic interactions of fish species that were predominantly zooplanktivorous and ultimately piscivorous were contrasted to assess their effect on interactions between cohorts of age-0 fish and zooplankton.
Ultimately piscivorous fish species were found to have a lower potential to affect zooplankton communities because of low reproductive potential and rapid trophic ontogeny.
