Finding Technical and Financial Assistance for Fish Barrier Removal and Mitigation

Manmade barriers can limit the movement of many aquatic species and prevent them from gaining access to critical habitats. For public entities and private individuals interested in the removal or mitigation of those barriers, both technical and financial assistance is available.

Has a New Pathway for Increased Mercury in Fish Been Found?

There is growing evidence that zebra mussels may be affecting the level of mercury in fish tissue by altering contaminant cycling in inland lakes. While the mechanism of this increase needs to be further studied, it likely means that fish consumption advisories will increase for those lakes invaded by zebra mussels.

The Importance of Fish for Native Freshwater Mussel Reproduction

To reproduce, freshwater mussels rely on fish to carry their young into new areas and disperse them when they are old enough. By conserving suitable fish habitat, it also allows us to indirectly conserve mussels by providing necessary resources for mussels to reproduce.
