Definition of planktivorous in English: planktivorousadjective ˌplaŋkˈtɪv(ə)rəs Feeding on plankton. shad are planktivorous fish Example sentencesExamples - From mid-June until October, Bythotrephes was the dominant diet of adult planktivorous fish (mostly whitefish) in Lake Constance.
- Furthermore, as large planktivorous fish usually select the largest prey items, a shift from producing many small to few large offspring can be considered rather detrimental to the survival of offspring.
- Hence, the effects of planktivorous fish through both predation on zooplankton and nutrient excretion act in concert and may be quantitatively important to shape the structure and dynamics of planktonic communities.
- Acanthurids are diurnal fishes, seeking cover at night, and most are herbivorous except one genus, Naso, which is planktivorous.
- Moreover, dense populations of planktivorous fish are expected to feed selectively on larger prey.
- The highly seasonal plankton blooms that typify the Antarctic continental shelf are paradoxical when considering the planktivorous diets of sponges.
- For instance, the introduction of Nile perch, a voracious predator, into Lake Victoria caused a precipitous decline of many small, planktivorous cichlids.
- When planktivorous fish dominated the food web, large zooplankton were rare and nutrient enrichment produced positive values of NEP by all three methods.
- The predatory impacts of Cercopagis pengoi, a planktivorous cladoceran first observed in Lake Ontario in 1998, were assessed by examining patterns in the distribution and population dynamics of macrozooplankton.
- These species are small-bodied, cold water species that are generalist feeders on planktivorous zooplankton and benthic organisms.
- An intriguing form of promiscuous spawning in some planktivorous cichlids (and at least one non-planktivorous cichlid as well) is termed ‘lekking,’ a Swedish word meaning ‘to play.’
- We used planktivorous fish to establish contrasting zooplankton communities in the two ponds.
- The leptocephalus is planktivorous as it drifts to coastal waters and develops into an elver, which feeds on aquatic insects, small crustaceans, and dead fish.
- In addition, a pair of antennal spines flare upon attack, transforming the larva into a prickly ball, difficult for small-mouthed planktivorous fishes to swallow.
- These regions of high productivity promote the development of plankton, which feeds planktivorous fish such as anchovies.
- Taken together with previously published information, our study reveals the biology of a remarkable relationship among closely coexisting diverse planktivorous seabird species.
- Similar declines have been noted for other planktivorous species of alcids in the North Pacific, and for Cassin's Auklets in British Columbia.
- This concurs with Calanus selection of oceanic winter habitats below depths where planktivorous fish can forage efficiently by sight.
- Results from this unplanned introduction suggest that invertebrate predators can have a rapid and lasting effect on prey populations, even in the presence of planktivorous fish.
- Altered light, temperature, and oxygen profiles in these brown-water lakes should reduce the foraging abilities of planktivorous fish and reduce predation on zooplankton and invertebrate predators such as Chaoborus.
