The increase in complexity of bottom habitat provided by zebra mussels caused an increase in amphipods. Predation by bluegill (Lepomis macrochirus) fish on amphipods was decreased by this complex habitat the mussels provide.

After the arrival of the zebra mussel, water clarity increased chlorophyll a decreased. Decreases were also seen in numbers of native bivalves and polychaetes. Gammarid amphipods and tubificid worms were unchanged.

Native plants Najas guadalupensis and Elodea canadensis, and the submersed annuals, Potamogeton foliosus, P. pusillus var. pusillus, and Najas flexilis returned likely due to the water clarity brought about by the introduction of non-native zebra and quagga mussels.

In Lake Erie, the rate of biosedimentation through pseudofeces production was very high (28mg/cm2 day at a density of 1180 individuals/m2) under turbid conditions, lending support to the hypothesis that zebra mussels (Dreissena polymorpha) are responsible for increased water clarity observed since mussel introduction.

Increasing amounts of pseudofeces and biodeposits could also have an impact on multiple trophic levels via changes to the physical environment. A current study in Brocton Shoal, Lake Erie, suggests that colonization of lakebed areas by dreissenid mussels (Dreissena polymorpha) and the consequent filling of remaining interstitial spaces with pseudofeces and fine-grained sediments may significantly eliminate valuable habitat native habitat . Brocton Shoal, once thought to be an important area for lake trout spawning, has diminished suitability as a spawning ground.
