|
Field
|
The presence of Daphnia lumholtz in Lake Champlain provides a large food resource for fish species, particularly juvenille fishes, in Lake Champlain during the summer when zooplankton densities are low.

Predation/Herbivory
|
Observational
|
Field
|
In the Texoma region of the United States, Daphnia lumholtzi is an important food resource for juvenile inland silversides, Menidia beryllina, in late summer when native zooplankton are far fewer.

Laboratory
|
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.
