5246 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Rhithropanopeus harrisii may have a negative impact upon local unionid populations, but this remains to be determined Texas 676
5247 Rhithropanopeus harrisii Predation/Herbivory Observational Field Rhithropanopeus harrisii likely plays a minor role in reduction of spat, Crassostrea virginica , possibly through predation. Chesapeake Bay, Virginia 38069
5430 Rhithropanopeus harrisii Predation/Herbivory Experimental Laboratory Rhithropanopeus harrisii reduced population size of native Iraqi crab, Elamenopsis kempi, in the Panama Canal through predation. Panama Canal, Panama 39602
5431 Rhithropanopeus harrisii Predation/Herbivory Anecdotal Field Mud crabs Rhithropanopeus harrisii were found in stomachs of several predatory fish (perch, fourhourned sculpin, roach, and pikeperch) according to local fishermen, and so effects on food webs were expected. Baltic Sea 38068
5432 Rhithropanopeus harrisii Predation/Herbivory Observational Field Stomach content of Rhithropanopeus harrisii contained species from Chlorophyta, Amphipoda, Ostracoda, Polychaeta, Gastropoda, and Bivalvia. The type of food consumed was significantly (P<0.05) dependent on the locality inhabited: the greater the biodiversity of the habitat, the richer the dietary composition. Baltic Sea 38054
5433 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Rhithropanopeus harrisii had a moderate to strong biopollution level (BPL=1-2) in three regions of the Baltic Sea (Vistula Lagoon, Gulf of Gdansk, Odra Lagoon). Baltic Sea 36470
5441 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Rhithropanopeus harrisii are believed to compete with other benthic organisms. 39694
5503 Rhithropanopeus harrisii Predation/Herbivory Observational Field The diet of Rhithropanopeus harrisii mostly consisted of algae, detritus, animal remains, and inorganic material. Odra Estuary, Poland 38050
5506 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Harris mud crab, Rhithropanopeus harrisii, are believed to alter food webs by predating and being predated upon by other benthic organisms. 38075
5730 Rhithropanopeus harrisii Predation/Herbivory Observational Field Several species of predatory fish in the Baltic Sea consumed Harris mud crab (Rhithropanopeus harrisii). Baltic Sea 40095
5731 Rhithropanopeus harrisii Predation/Herbivory Experimental Laboratory The Harris mud crab (Rhithropanopeus harrisi) reduced consumption in lower salinity, suggesting different feeding rates across salinity gradients. Kiel, Germany 40096
5733 Rhithropanopeus harrisii Predation/Herbivory Experimental Laboratory Invasive Harris mud crabs, Rhithropanopeus harrisii, and native perch, Perca fluviatilis, both consume marine isopods, Idotea balthica, in the Baltic Sea. Laboratory experiments indicate Harris mud crabs and perch have an antagonistic relationship and reduce predation on isopods when both predators are present. Archipelago Sea Research Institute, University of Turku 40099
5779 Rhithropanopeus harrisii Predation/Herbivory Observational Field Harris mud crabs, Rhithropanopeus harrisii, in the Dead Vistula mainly consumed plants, invertebrates, such as polychaete worms and mussels, and dead organic material. Dead Vistula, Poland 38063
5780 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Harris mud crab, Rhithropanopeus harrisii, have been known to consume snails, isopods, mussels, shrimp, ragworms, fly larvae, and plant material in the Kiel canal, Azov Sea, and Haff of Vistula. 38063
5781 Rhithropanopeus harrisii Predation/Herbivory Anecdotal Field The gut contents of European eels, Anguilla anguilla, from alimentary canals in the Dead Vistula had traces of Harris mud crab, Rhithropanopeus harrisii in their gut contents. Dead Vistula, Poland 38063
6079 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A While impacts are scarce, researchers predict that introduction of Harris mud crab (Rhithropanopeus harrisii) in Finland, alterations to the benthic community were expected as it is a new functional species in the area. Baltic Sea 38068
6080 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Rhithropanopeus harrisii can consume Dreissena polymorpha but the degree of its potiential impact on Dreissenid population is unknown. Vistula Lagoon, Baltic Sea 38078
6081 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A Besides Dreissena polymorpha, the Harris mud crab Rhithropanopeus harrisii also consumed Nereis diversicolor, Mytilus edulis, and Cordylophora caspia, along with Cladophora sp. and Enteromorpha sp. Vistula Lagoo, Baltic Sea 38078
6082 Rhithropanopeus harrisii Predation/Herbivory Anecdotal N/A A number of coastal mud crabs, including Rhithropanopeus harrisii, are reported as major predators on young oysters and hard clams. Atlantic Coast, US 14565
6083 Rhithropanopeus harrisii Predation/Herbivory Experimental Laboratory In lab experiments, Harris mud crabs (Rhithropanopeus harrisii) opened and consumed epifaunal mytiliform bivalves. Choptank River, Chesapeake Bay, USA 14343
7169 Rhithropanopeus harrisii Predation/Herbivory Observational Field Rhithropanopeus harrisii prey on Idotea balthica and significantly reduce populations in the Baltic Sea. Baltic Sea, Finland 42149
