Fish. (1) Prior to the form and content of a Final Agreement and a Tripartite Final Agreement being concluded by the negotiators for the Parties and Manitoba, the Parties and Manitoba will negotiate with respect to and attempt to reach agreement on the Jurisdiction of Sioux Valley with respect to fish, fisheries and related matters.
Fish. Data on lakewide phosphorus loadings needs to be collected and reported annually in a manner that allows long-term trends to be discerned. • A number of Lake Erie fish habitat mapping initiatives are either underway or proposed. These projects will provide inventory data regarding fish habitat quantity, supply, and changes over time. In addition, Ohio Department of Natural Resources (ODNR) has been exploring the relationship between Lake Erie environmental conditions, including habitat, and known fish reproductive centers or hotspots. A conceptual framework is under development and will be used to identify the specific driving environmental forces that produce these observed, repeatable patterns in fish community composition and reproduction. It is hypothesized that the driving forces are linked to tributary conditions versus open lake conditions. If this is the case, fish management actions will become more watershed based versus open-lake focused. The LaMP offers an important opportunity to link the results of both projects into a more comprehensive picture of Lake Erie fish habitat needs. • Genetic diversity in fish is measured by determining whether discreet stocks (i.e. river spawning versus reef spawning) exist within a particular species and population. Research has begun to identify genetic markers for Lake Erie larval fish. If a relatively inexpensive genetic marking technique can be developed, monitoring of fish stocks can be more detailed. The overall result will be better information on the diversity and health of particular Lake Erie fish species. • Further research into alternative methods of sea lamprey control that maximize effectiveness of the control efforts while minimizing their economic and environmental costs.

Fish. Yellow perch stocks are recovering; however, the top predator species populations of walleye, lake trout, and lake whitefish are struggling. Contaminant levels, specifically PCBs and mercury continue to affect fish consumption. (Environment Canada and U.S. EPA, 2009c) Consumption restrictions in Ontario on Lake Erie sport fish are caused by PCBs (82%) and mercury (18%). In 2002 these percentages were 70% and 30%, respectively. Other contaminants such as DDT and metabolites, hexachlorobenzene, octachlorostyrene, chlordane and lindane are often detected in Lake Erie sport fish, but do not cause consumption restrictions, and concentrations have declined over the years. In recent years, dioxins and furans have been monitored in species expected to have the highest concentrations (e.g. carp, lake whitefish), but have not caused consumption restrictions. Comparing data across the Canadian waters of the Great Lakes, Lake Erie has the lowest proportion of sport fish species with consumption restrictions at 15.7% (in 2002 that number was 17.4%). (Environment Canada and U.S. EPA, 2008)
Fish. Fish were collected at each habitat site in late summer or early autumn of 1998-2003. Fish community data has been analyzed for 1998-2002, and samples collected in 2003 are currently being processed. Species richness, abundance, percent composition, and Index of Biotic Integrity scores are being used to assess the responses of fish assemblages to BMPs. From 1998- 2003, boney structures (i.e. scales, fin rays, otoliths of selected fish species were collected) to evaluate age structure and growth rates. Determinating fish growth rates is ongoing and growth data from largemouth bass, bluegill, green sunfish, and longear sunfish from 1998-2001 have been analyzed. Growth rates and age structure of white sucker, yellow bullhead, and creek chub is currently being analyzed and assessed.
Fish. The most recent Peel River fish contaminants study was done in 1999. This study was carried out due to continued concerns from Fort XxXxxxxxx residents regarding the safety of eating fish from the Peel River. The concerns were related to an abandoned Shell oil exploration site and possible point source of contaminants upstream on the Peel River near the Peel/Caribou River confluence. A total of 30 fish, including ten each of inconnu (Stenodus leucichthys), broad whitefish (Coregonus nasus) and burbot (Xxxx xxxx), were examined for a suite of heavy metals and organochlorines. Local fishermen at traditional fishing sites captured all fish. Based on the results of the study, the three fish species from the Peel River were deemed safe for human consumption. No further studies were recommended at that time.
