Regional Impacts
| Economic Impact | Fisheries | |
| Large population outbreaks occurred in lakes of the Nile Delta in 1957-1958, and 1964-65, breaking fishnets, killing fish, and interfering with more desirable crab fisheries ('red crabs', not identified) (Anonymous 1965). | ||
| Ecological Impact | Competition | |
| Accounts of C. sapidus population outbreaks in the Nile Delta in the 1950s and 1960s are suggestive of competition with native crabs ('red crabs', not identified) (Anonymous 1965). Zenetos et al. (2011) listed C. sapidus as 'invasive' in the eastern Mediterranean, also suggestive of competition. However, competitive effects of C. sapdius on other crabs or marine biota have not been studied in the Mediterranean. | ||
