| Impact Description | If Daphnia lumholtzi outcompetes native zooplankton populations during their normal peak abundance in late summer, this may adversely impact planktivorous fish relying on that critical food source but unable to tolerate D. lumholtzi's spines. Larval and juvenile stages of fish are more likely to be unable to consume D. lumholtzi due to gape (mouth-size) limitation. |
