Impact ID Scientific Name Impact Type Study Type Study Location Impact Description Geographic Location Reference
5757 Anguillicola crassus Predation/Herbivory Observational Field Smaller European eels, Anguilla anguilla, that fed primarily on invertebrates had a greater number of Anguillicola crassus nematode parasites than larger eels that ate predominantly fish. Loch Lomond, Scotland 40138
5761 Anguillicola crassus Predation/Herbivory Observational Field Only third and fourth stage larvae of Anguillicola crassus were found in the swim bladders of fish. These late stage larvae were previously thought to only infect eels. Lake IJssel, Netherlands 40940
5762 Anguillicola crassus Predation/Herbivory Experimental Laboratory Anguillicola crassus nematodes removed from the swim bladders of smelt (Omerus eperlanus L) and ruffe (Gymnocephalus cernuus L) can infect European eels (Anguilla anguilla), indicating prey fish can transmit nematodes to eels. Lake IJssel, Netherlands 40941
5768 Anguillicola crassus Predation/Herbivory Experimental Field Larger, older eels at the elver and yellow stages were more likely to have a severe Anguillicola crassus infections. Chesapeake Bay 40149
5772 Anguillicola crassus Predation/Herbivory Observational Field Larger and heavier European eels, Anguilla anguilla, had higher Anguillicola crassus parasite infections. Cape Breton Island, Nova Scotia 40145
6116 Anguillicola crassus Predation/Herbivory Observational Field The paratenic host for Anguillicola crassus, the Eurasian ruffe, had the highest rates of infection in the summer. Also, smaller ruffe less than 8 cm had the heaviest infections. Vista Lagoon, Poland 40933
6122 Anguillicola crassus Predation/Herbivory Observational Field Anguillicola crassus were found in the swim bladders of several fish species. When consumed, the infection can likely be passed to eels. Lake IJssel, Netherlands 40940
6133 Anguillicola crassus Predation/Herbivory Observational Field Anguillicola crassus larvae were detected in ruffes regurgitated by cormorants. The ruffe is a major component of cormorant diets. It was not clear whether cormorants select for infected fish. Vistula Lagoon, Poland 40953
6135 Anguillicola crassus Predation/Herbivory Experimental Laboratory Laboratory tests indicate cyclopoid copepods in the Acanthocyclops vernalis–robustus–americanus complex are likely natural intermediate hosts for Anguillicoloides crassus. Cooper River, South Carolina, USA 40955
6138 Anguillicola crassus Predation/Herbivory Observational Field Anguillicola crassus can infect black goby and ruffe. When these species are consumed, the infection can likely be passed to eels. Oskarshamn nuclear power station, Baltic Ocean, Sweden 40965
6140 Anguillicola crassus Predation/Herbivory Experimental Laboratory Third-stage larvae Anguillicola crassus can infect and use Galba corvus as a suitable paratenic host. When these species are consumed, the infection can likely be passed to eels. 40973
6142 Anguillicola crassus Predation/Herbivory Observational Field In the Baltic Sea, deep-snouted pipefish and black goby were infected with stage 3-4 Anguillicola crassus larvae. When these species are consumed, the infection can likely be passed to eels. Wismar Bay, Baltic Sea 40978
6146 Anguillicola crassus Predation/Herbivory Observational Field Third-stage larval Anguillicola crassus can infect amphibians and aquatic insects. This indicates that amphibians and larval aquatic insects can act as paratenic hosts. When these species are consumed, the infection can likely be passed to eels. Bohemia, Czech Republic 40974
6147 Anguillicola crassus Predation/Herbivory Experimental Laboratory In greenhouse cultured ponds, ostracod Physocypria nipponica were the only intermediate host Anguillicola crassus. The nematode larvae from ostracods can then infect Japanese eels. Isshiki, Aichi Prefecture, Japan 40975
6159 Anguillicola crassus Predation/Herbivory Observational Field European eel head morphology is correlated to diet specialization. Eels with broader heads consumed more fish. Eels with broader heads and consequently piscivorous diets were more likely to have Anguillicola crassus. This increased infection rate is likely the result of greater parasite exposure in paratenic hosts. England 40996
6164 Anguillicola crassus Predation/Herbivory Observational Field One Anguillicola crassus larva was found in the liver of a bighead goby from the River Danube. When these species are consumed, the infection can likely be passed to eels. River Danube, Slovakia 41007
6167 Anguillicola crassus Predation/Herbivory Observational Field Anguillicola crassus were found to use ruffes and sunfish as a paratenic host. When these species are consumed, the infection can likely be passed to eels. Upper Lake Constance, German 41016
6186 Anguillicola crassus Predation/Herbivory Observational Field In a recently invaded system, smaller European eels were more severely infected with Anguillicola crassus than larger eels. Smaller eels feed primarily on invertebrates, and larger eels feed primarily on fish. Diet and Anguillicola crassus infection rates appear to be linked in recently infected systems. Loch Lomond, Scotland 41030
6194 Anguillicola crassus Predation/Herbivory Observational Field A third of round gobies collected from the Rhine River were infected with Anguillicola crassus. The larval parasites were found in acanthocephalan cysts, which likely allows it to evade the gobies immune system. Using round gobies as a paratenic host is another route Anguillicola crassus can infect European eels. Rhine River 41059
6338 Anguillicola crassus Predation/Herbivory Observational Field Silver stage eels collected from Lake Balaton were significantly more infected than yellow stage eels. This could be due to dietary shifts to piscivory before silvering, indicating eels with piscivorous diets are more likely to be infected with Anguillicola crassus. Lake Balaton, Hungary 41015
