Regional Impacts
| Ecological Impact | Competition | |
| Rhithropanopeus harrisii had a period of high abundance in the Vistula Lagoon for about 20 years after its first record, when its larvae dominated the local plankton (Jazdzewski and Konopacka 1993). | ||
| Ecological Impact | Food/Prey | |
| Rhithropanopeus harrisii is considered to play an important part in the benthic foodwebs of the Vistula Lagoon (Ezhova et al. 2005; Zaiko et al. 2011). | ||
