2065 Hypophthalmichthys molitrix Competition Observational Field Silver carp (Hypophthalmichthys molitrix) were competing with commercially valuable native fish for zooplankton. The silver carp had been stocked in an Israeli lake. Lake Kinneret, Israel 22931
2154 Hypophthalmichthys molitrix Competition Experimental Field Silver Carp compete for algae as a food source with a small cladoceran, Moina micrura. Lake Donghu, China 22913
2636 Hypophthalmichthys molitrix Competition Observational Field There was diet substantial overlap of Bighead and Silver Carps with Gizzard Shad and less overlap with Bigmouth Buffalo in the Illinois and Mississippi rivers. No overlap with paddlefish. Although there was little evidence that bighead and silver carp were reducing zooplankton abundance, results did not rule out the possibility that these species could limit food resources for native fishes as the populations of bigheaded carp continue to increase in the Illinois and Mississippi rivers. 18463
4073 Hypophthalmichthys molitrix Competition Observational Field Gizzard Shad body condition and catch per unit effort decreased after the introduction Bighead Carp and Silver Carp, and increased following implementation of contractual harvest as a management and control method, suggesting higher availability of a shared forage resource (zooplankton) 35727
4079 Hypophthalmichthys molitrix Competition Observational Field Study results may suggest that silver carps (Hypophthalmichthys molitrix) are influencing native planktivore body condition. Gizzard Shad and Bigmouth Buffalo body condition declined significantly with increases in commercial harvest of silver and Asian carps (linked to density and biomass). 17189
5802 Hypophthalmichthys molitrix Competition Observational Field Silver car, Hypophthalmichthys molitrix, had a direct negative impact on the abundance of adult sport fish. The suggested mechanism for decline was thought to be competition for zooplankton and reducing juvenile sport fish recruitment. Mississippi River and La Grange Reach 40374
5832 Hypophthalmichthys molitrix Competition Observational Field Stable isotope analysis indicated that silver carp, Hypophthalmichthys molitrix, diet overlapped with bighead carp (94.1%), gizzard shad (90.6%), and paddlefish (26.8%). This trophic overlap could threaten fish biodiversity. Missouri River, Missouri 40452
5852 Hypophthalmichthys molitrix Competition Experimental Laboratory The unionid mussel, fatmucket, had reduced growth rates and increased movement in laboratory experiments with silver carp (Hypophthalmichthys molitrix) present. This indicates competition between these species for food resources. Carbondale, IL, USA 40443
5902 Hypophthalmichthys molitrix Competition Observational Field Analysis of long-term fish monitoring programs indicate that the body condition and catch-per-unit-effort (CPUE) of gizzard shad and bigmouth buffalo is inversely related population sizes of silver carp (Hypophthalmichys molitrix). This study is further evidence that silver carp suppress other planktivores by consuming zooplankton. Upper Illinois River, USA 40662
5920 Hypophthalmichthys molitrix Competition Observational Field According to stable isotope analysis, silver carp (Hypophthalmichthys molitrix) had overlapping trophic niches with other fish species in the Missouri River. Its highest overlap was with bigmouth buffalo (93.6%), followed by gizzard shad (90.6%) and American paddlefish(35.4%). Overall, bighead carps trophic overlap with native species was 71% on average. This competition could have negative effects on native fish species. Missouri River, USA 40680
6021 Hypophthalmichthys molitrix Competition Observational N/A Silver carp (Hypophthalmichthys molitrix) is a filter feeder and competes with virtually every fish species in the Mississippi River basin that forage on planktonic organisms. 40710
6023 Hypophthalmichthys molitrix Competition Observational Field Silver carp (Hypophthalmichthys molitrix) has been found to have an overlapping diet with two native Great Lakes filter-feeder species, the Gizzard Shad and the Bigmouth Buffalo. La Grange Reach, Illinois River, USA 18463
6110 Hypophthalmichthys molitrix Competition Observational Field Analysis of long-term fish monitoring programs indicate that the body condition and catch-per-unit-effort (CPUE) of gizzard shad and bigmouth buffalo is inversely related population sizes of silver carp (Hypophthalmichys molitrix). This study is further evidence that silver carp suppress other planktivores by consuming zooplankton. Mississippi River Basin, USA 40622
