2151 Hypophthalmichthys molitrix Predation/Herbivory Experimental Field The species composition of cladocerans changed with the stocking of Silver Carp, shifting from large-bodied to small-bodied cladocerans. Also caused suppression of total zooplankton abundance. Lake Donghu, China 22835
2153 Hypophthalmichthys molitrix Predation/Herbivory Experimental Field Silver Carp can suppress zooplankton through herbivory of algal biomass in the form available to zooplankton. Silver carp can shift claderoceran composition based on what species they captured as they filter feed and the life stage of the prey. Lake Donghu, China 22913
2155 Hypophthalmichthys molitrix Predation/Herbivory Experimental Field Silver Carp predation supressed the whole zooplankton community also resulting in a shift from large-bodied cladocerans to small-bodied ones. Lake Donghu, China 23557
2176 Hypophthalmichthys molitrix Predation/Herbivory Observational Field A 22-year presence of Silver Carp (Hypophthalmichthys molitrix) in the Illinois River coincided with a reduction in phytoplankton and a 90% reduction in zooplankton. Illinois River 31254
2523 Hypophthalmichthys molitrix Predation/Herbivory Observational Field Silver Carp (Hypophthalmichthys molitrix) showed differential selectivity in phytoplankton consumption, with euglenoid algae being preferentially selected and cyanobacteria preferentially avoided. This selective predation could alter plankton abundance. Forest Home Chute, Mississippi River, Mississippi, US 27217
2524 Hypophthalmichthys molitrix Predation/Herbivory Anecdotal N/A A model suggests that Silver and Bighead Carp would affect Lake Erie’s food web by competing with other planktivorous fishes and by providing additional prey for piscivores. 30222
2635 Hypophthalmichthys molitrix Predation/Herbivory Experimental Field Bighead and Silver Carps stocked in reservoirs reduced zooplankton and phytoplankton biomass. Israel 23525
4075 Hypophthalmichthys molitrix Predation/Herbivory Observational Field Establishment and population growth of Bighead and Silver Carps is associated with changes in zooplankton community composition and biomass across a pre- versus post-establishment comparison and a gradient of abundance in the the Illinois River. Illinois River, Illinois 27200
4084 Hypophthalmichthys molitrix Predation/Herbivory Observational Field Viable cells of several different types of phyoplankton were found in the hindgut of Bighead and Silver Carp, suggesting that these fish can alter the phytoplankton species composition by increasing the abundance of phytoplankton species able to resist predation and digestion. Lake Balaton, Hungary 30221
4086 Hypophthalmichthys molitrix Predation/Herbivory Experimental Laboratory Age-0 Blue and Channel Catfish showed both survival and growth on a diet of Silver Carp fecal pellets, with Blue Catfish showing no difference in survival or growth rate compared to a control diet of chironomids. Silver Carp fecal pellets may provide a potential pathway for nutrient transfer between pelagic and benthic habitats. 35730
5801 Hypophthalmichthys molitrix Predation/Herbivory Observational Field While silver carp, Hypophthalmichthys molitrix, did not significantly reduce zooplankton biomass or abundance in the Illinois River basin, silver carp did significantly reduce zooplankton taxonomic richness across the basin. Illinois River 40372
5803 Hypophthalmichthys molitrix Predation/Herbivory Experimental Field The size of phytoplankton filtered by silver carp, Hypophthalmichthys molitrix, was 8-100 micrometers. Montgomery, Alabama 15090
5808 Hypophthalmichthys molitrix Predation/Herbivory Experimental Laboratory In mesocosms with silver carp, Alphaproteobacteria and Actinobacteria increased in abundance while cyanobacteria did not. This provides further evidence silver carp can influence bacterioplankton community composition. Erhai Lake, Yunnan Plateau, China 40408
5810 Hypophthalmichthys molitrix Predation/Herbivory Anecdotal N/A Ecological network models indicate that silver carp, Hypophthalmichthys molitrix, have a stronger impact on predators than prey. Silver carp influence the food chain as a new food source for predators. 40404
5812 Hypophthalmichthys molitrix Predation/Herbivory Experimental Field In enclosure experiments, silver carp (Hypophthalmichthys molitrix) reduced cladoceran biomass, likely reducing zooplankton consumptive pressure on phytoplankton. Liuxihe Resevoir, South China 40405
5829 Hypophthalmichthys molitrix Predation/Herbivory Observational Field The diet of silver carp, Hypophthalmichthys molitrix, included cyanobacteria, LGB algae, green algae, diatoms, Rotifera, Copepoda, and Cladocera from 30 different genera. The foreguts of 83 silver carp collected in Kentucky Lake contained phytoplankton (63.5%), zooplankton (33.8%), and heterotrophic flagellates (2.7%) by volume. This is first study in mainstem reservoir for flood storage and might explain differences with previous studies. Kentucky Lake, Kentucky 40446
5830 Hypophthalmichthys molitrix Predation/Herbivory Observational Field The majority (83%) of phytoplankton found in the hindgut of silver carp, Hypophthalmichthys molitrix, were poorly digested with intact cells walls and organelles. All nine living phytoplankton cells in silver carp in were noncolonial coccoid algae. This indicates silver carp do not digest phytoplankton efficiently, and silver carp could influence food web dynamics by dispersing phytoplankton. Kentucky Lake, Kentucky 40447
5831 Hypophthalmichthys molitrix Predation/Herbivory Observational Field The hindguts of silver carp, Hypophthalmichthys molitrix, contained non-colonial coccoid algae, diatom, and green algae from 10 genera. Kentucky Lake, Kentucky 40447
5834 Hypophthalmichthys molitrix Predation/Herbivory Experimental Laboratory Juvenile silver carp (Hypophthalmichthys molitrix ) had no innate response to native fish predators, including largemouth bass, smallmouth bass, and longnose gar. This suggests that silver carp might be susceptible to native predators and struggle to persist in areas with diverse predator communities. Kaskaskia Biological Station, Sullivan, Illinois 40458
5841 Hypophthalmichthys molitrix Predation/Herbivory Observational Field Silver carp (Hypophthalmichthys molitrix) selectively consumed euglenoid algae and consumed colonial algae and diatoms variability. Forest Home Chute, Warren County, Mississippii 40416
5842 Hypophthalmichthys molitrix Predation/Herbivory Anecdotal N/A Silver carp (Hypophthalmichthys molitrix) may create upward and downward cascades in floodplain lakes by the selective consumption and digestion of phytoplankton. These cascades could extend to zooplankton, other planktivores, and nutrient fluxes. Forest Home Chute, Warren County, Mississippii 40416
5843 Hypophthalmichthys molitrix Predation/Herbivory Experimental Laboratory Phytoplankton biomass was higher in mesocosms with silver carp (Hypophthalmichthys molitrix). This increase in phytoplankton was a result of carp consumption of zooplankton rather than changes in nutrient cycling. Taihu Lake, China 40429
5844 Hypophthalmichthys molitrix Predation/Herbivory Observational Field Gizzard shad catch per unit effort (CPUE) declined in the Wabash River were correlated with increases in the CPUE of silver carp (Hypophthalmichthys molitrix). There were no other significant patterns with fish populations in the Wabash River after silver carp introductions. Wabash River, Indiana 40431
