Until the mid-1950’s, a diverse assemblage of deepwater ciscoes including bloater (Coregonus hoyi) inhabited Lake Ontario. Currently, only the shallow-water form of Cisco (C. artedi) remains. The Lake Ontario Committee has established a plan to reestablish a self-sustaining deepwater cisco population within 25 years. The work is supported by the Lake Ontario FCOs and guided by the Strategies for the Reestablishment of Native Deepwater Ciscoes in Lake Ontario.
Previous attempts to rehabilitate Great Lakes coregonines (Coregonus spp.) have been unsuccessful due to the reliance on fry and stocking on top of existing populations that made evaluations difficult. After the demise of cisco and deepwater coregonines during 1940-50, non-native alewife (Alosa psuedoharengus) and rainbow smelt (Osmerus mordax), replaced native species as forage of top predators. A basin-wide decline of both rainbow smelt and alewive has generated broad inter-lake, international interest and urgency in re-establishing species such as cisco (C. artedii), bloater (C.

"The U.S.-Canada Great Lakes Islands Project is a binational collaboration among 35 researchers, policymakers, and islanders who want to conserve the globally significant biological integrity of the 3 , islands. The purpose of the project is to serve as 1) a catalyst to start a basin-wide "conversation" about the islands and conservation of biological diversity and 2) a central base or focal point for activities, data, and information about the islands.

Fisheries managers attempt to produce the highest possible sustained benefits for people by actions that influence aquatic organisms, their environments, and their human users. Fisheries management decisions have consequences that extend beyond the participants in recreational and commercial fisheries. Within Michigan alone, licensed anglers contribute nearly $2 billion to the state economy.
This project seeks to improve the understanding of use impairment that exists due to the contamination of the Great Lakes by metals and organochlorines. The specific objective is to develop a new remediation technology based on nanostructured materials for the rapid, low-cost, clean and effective removal of mercury, chromium and polychlorinated biphenyls (PCBS) in the Great Lakes. We have recently reported the use Palladium nanoparticles (Pd-NPs) and their novel applications for the rapid conversion of Cr(VI) to Cr(III)1,2.
