Regional Impacts
Ecological Impact | Food/Prey | |
Food/Prey- Grandidierella japonica is the predominant amphipod in the Tijuana River estuary, San Diego, California. It has become a major food item for several native fishes (Longjaw Mudsucker-Gillichthys mirabilis; Staghorn Sculpin- Leptocottus armatus; California Halibot- Paralichthys californicus (West et al. 2003). In the Tijuana estuary, this amphipod was a major user of detritus from invasive Tamarix shrubs (Whitcraft et al. 2008), potentially transferring this resource from the marsh sediments to higher trophic levels. | ||
