| Impact Description | A decline in native cladocerans following the introduction of Bythotrephes longimanus (spiny waterflea) has been observed in Lake Huron and Lake Michigan. In Lake Erie, the detection of B. longimanus in 1985 was also accompanied by a decline in multiple species of cladocerans (e.g., Eubosmina coregoni, Daphnia mendotae, Daphnia retrocurva), including an almost complete absence of Diaphanosoma spp. wherever B. longimanus was present in 1986. |
