Definition of planktivorous in English:



  • Feeding on plankton.

    ‘shad are planktivorous fish’
    • ‘This concurs with Calanus selection of oceanic winter habitats below depths where planktivorous fish can forage efficiently by sight.’
    • ‘We used planktivorous fish to establish contrasting zooplankton communities in the two ponds.’
    • ‘Acanthurids are diurnal fishes, seeking cover at night, and most are herbivorous except one genus, Naso, which is planktivorous.’
    • ‘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.’
    • ‘Moreover, dense populations of planktivorous fish are expected to feed selectively on larger prey.’
    • ‘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.’
    • ‘These regions of high productivity promote the development of plankton, which feeds planktivorous fish such as anchovies.’
    • ‘The highly seasonal plankton blooms that typify the Antarctic continental shelf are paradoxical when considering the planktivorous diets of sponges.’
    • ‘These species are small-bodied, cold water species that are generalist feeders on planktivorous zooplankton and benthic organisms.’
    • ‘Taken together with previously published information, our study reveals the biology of a remarkable relationship among closely coexisting diverse planktivorous seabird species.’
    • ‘From mid-June until October, Bythotrephes was the dominant diet of adult planktivorous fish (mostly whitefish) in Lake Constance.’
    • ‘Similar declines have been noted for other planktivorous species of alcids in the North Pacific, and for Cassin's Auklets in British Columbia.’
    • ‘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.’
    • ‘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.’
    • ‘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.’
    • ‘For instance, the introduction of Nile perch, a voracious predator, into Lake Victoria caused a precipitous decline of many small, planktivorous cichlids.’
    • ‘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.’
    • ‘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.’
    • ‘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.’’
    • ‘When planktivorous fish dominated the food web, large zooplankton were rare and nutrient enrichment produced positive values of NEP by all three methods.’
