Knowledge of the population structure of northern pike (Esox lucius), an important recreational and top-level piscivore, is essential to Nebraska Sandhill lakes management.
Corroborating these field observations, experimental studies have demonstrated that large (160-200 mm) perch are efficient predators on small (60-80 mm) perch, whereas individuals slightly larger (90-110 mm) are not susceptible to cannibalism from these piscivore s (Ekl[ddot{o}]v 1992, Ekl[ddot{o}]v and Diehl 1994).
The highest proportion of piscivorous fishes in commercial landings is observed in Kaniv Reservoir, where the piscivore percentage has increased from 8.2 % in 2004 to 14.0 % in 2013 (35.0 to 69.7 tons).
Relationships between the occupancy of five functional feeding groups and Plains Topminnow persistence were recognized; however, only in the Elkhorn river basin were two trophic guilds (i.e., piscivore and benthic invertebrate consumers) both correlated to Plains Topminnow extirpation.
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.
Predatory behaviour and selectivity of a primary piscivore: comparison of fish and non-fish prey.
kelberi, a voracious piscivore that was introduced in the 1950s into Lajes Reservoir, an oligotrophic and physically low-complex impoundment in Brazil, is first described.
For this, species were allocated to feeding groups (based on Krumme et al., 2004 and Elliott et al., 2007): zooplanktivore (ZP); detritivore (DV); piscivore (PV); zoobenthivore (ZB); opportunist/ omnivore (OP).
Five fish species with different feeding habits were selected: Pseudoplatystoma corruscans (Agassiz in Spix & Agassiz 1829) (piscivore); Schizodon borellii (Boulenger 1900) (herbivore), Prochilodus lineatus (valenciennes 1836) (iliophagous); Leporinus friderici (Bloch 1794) and Pterodoras granulosus (valenciennes in Humboldt & valenciennes 1821) (omnivores).
