Regional Impacts
| Ecological Impact | Herbivory | |
| Early anecdotal observations indicated that carp rapidly consumed or uprooted submerged vegetation (Water-Celery, Vallisneria americana) in the Sacramento Delta, eliminating a major food for waterfwel (Smith 1895; Dill and Cordone 1997). | ||
| Ecological Impact | Bioturbation | |
| Carp extensively dug up the sediment, muddying the waters, and potentially degradeng the habitat for other fishes (Smith 1896; Dill and Cordone 1997). | ||
| Economic Impact | Fisheries | |
| Carp have and continue to support a small commercial fishery in the Delta, and are consumed by European and Asian immigrants (Smith 1896; Dill and Cordone 1997). | ||
