The Detroit River: Effects of contaminants and human activities on aquatic plants and animals and their habitats
Bruce A. Manny, David Kenaga
1991, Hydrobiologia (219) 269-279
Despite the extensive urbanization of its watershed, the Detroit River still supports diverse fish and wildlife populations. Conflicting uses of the river for waste disposal, water withdrawals, shipping, recreation, and fishing require innovative management. Chemicals added by man to the Detroit River have adversely affected the health and habitats of...
Diet of juvenile lake trout in southern Lake Ontario in relation to abundance and size of prey fishes, 1979-1987
Joseph H. Elrod, Robert O’Gorman
1991, Transactions of the American Fisheries Society (120) 290-302
We examined the diet of juvenile lake trout Salvelinus namaycush (<450 mm, total length) in Lake Ontario during four sampling periods (April–May, June, July–August, and October 1979–1987) in relation to changes in prey fish abundance in the depth zone where we caught the lake trout. Over all years combined, slimy...
Effect of environment on reproduction and growth of Mysis relicta
Alfred M. Beeton, John E. Gannon
1991, American Fisheries Society Symposium (9) 144-148
Published and unpublished data were examined to determine whether the time to first reproduction, brood size, and growth rate of Mysis relicta are related to environmental conditions. Time to first reproduction ranged from 1 year in eutrophic lakes to 4 years in a ultraoligotrophic lake. Mysids in nutrient-rich lakes may...
Changes in the nearshore and offshore zooplankton communities in Lake Ontario: 1981-88
Ora E. Johannsson, Edward L. Mills, Robert O’Gorman
1991, Canadian Journal of Fisheries and Aquatic Sciences (48) 1546-1557
We examined trends and factors influencing changes in nearshore and offshore zooplankton abundance and composition in Lake Ontario between 1981 and 1988. In the nearshore (southshore and eastern basin), zooplankton abundance decreased and shifts occurred in the relative abundances of Bosmina longirostris and Daphnia retrocurva (eastern basin) and Daphnia retrocurva...

Thomas A. Edsall, Bruce A. Manny, Donald W. Schloesser, Susan J. Nichols, Anthony M. Frank
1991, Hydrobiologia (219) 353-361
In April through October 1986, we sampled sediments and populations of nymphs of the burrowing mayfly, Hexagenia limbata (Serville), at 11 locations throughout the connecting channels of the upper Great Lakes, to determine if sediment contaminants adversely affected nymph production. Production over this period was high (980 to 9231 mg...
Heavy metal contamination of sediments in the upper connecting channels of the Great Lakes
S. Jerrine Nichols, Bruce A. Manny, Donald W. Schloesser, Thomas A. Edsall
1991, Hydrobiologia (219) 307-315
In 1985, sampling at 250 stations throughout the St. Marys, St. Clair, and Detroit rivers and Lake St. Clair — the connecting channels of the upper Great Lakes — revealed widespread metal contamination of the sediments. Concentrations of cadmium, chromium, copper, lead, mercury, nickel, and zinc each exceeded U.S. Environmental...
Growth and survival of stocked lake trout with nuclear cataracts in Lake Ontario
Harold L. Kincaid, Joseph H. Elrod
1991, North American Journal of Fisheries Management (11) 429-434
Four strains of yearling lake trout Salvelinus namaycush from the 1985 and 1986 year-classes at the Allegheny National Fish Hatchery were evaluated for nuclear cataracts prior to stocking in Lake Ontario in June 1986 and 1987. Lake trout recaptured by bottom trawling from April to August 1987 and 1988 were examined for...
Distribution, abundance, and biology of the alewife in U.S. waters of Lake Superior
Charles R. Bronte, James H. Selgeby, Gary L. Curtis
1991, Journal of Great Lakes Research (17) 304-313
Alewives (Alosa pseudoharengus) were first reported in Lake Superior in 1954 and gradually increased in abundance in the late 1950s. In the 1960s and early 1970s, the fish were widespread in the lake but scarce. We determined the more recent abundance and distribution of alewives by cross-contour trawling in the...
Heavy metals in aquatic macrophytes drifting in a large river
Bruce A. Manny, Susan J. Nichols, Donald W. Schloesser
1991, Hydrobiologia (219) 333-344
Macrophytes drifting throughout the water column in the Detroit River were collected monthly from May to October 1985 to estimate the quantities of heavy metals being transported to Lake Erie by the plants. Most macrophytes (80–92% by weight) drifted at the water surface. Live submersed macrophytes made up the bulk...
Comment on “Macrodispersion in sand-shale sequences” by A. J. Desbarats
Daniel J. Goode, Allen M. Shapiro
1991, Water Resources Research (27) 135-139
Desbarats [1990] used a particle-tracking scheme to investigate the physics of three-dimensional solute transport in aquifers composed of two porous media of different hydraulic conductivities. The spatially heterogeneous fluid velocity was assumed to be the only mechanism of solute...
Acute toxicities to larval rainbow trout of representative compounds detected in Great Lakes fish
Carol Cotant Edsall
1991, Bulletin of Environmental Contamination and Toxicology (46) 173-178
In recent years the National Fisheries Research Center-Great Lakes has ranked the potential hazard to fish and invertebrates of various chemical compounds detected in two Great Lakes fishes-- lake trout, Salvelinus namaycush, and walleye, Stizostedion vitreum vitreum (Hesselberg and Seelye 1982). This hazard assessment has included the identification of the...
Influence of nearshore structure on growth and diets of yellow perch (Perca flavescens) and white perch (Morone americana) in Mexico Bay, Lake Ontario
Robert J. Danehy, Neil H. Ringler, John E. Gannon
1991, Journal of Great Lakes Research (17) 183-193
The growth diets of 969 yellow perch (Perca flavescens) and white perch (Morone americana) caught at 3.3 and 7.0 m depths were compared between two cobble/rubble shoals and two featureless sand sites in Mexico Bay, eastern Lake Ontario during 1981. The growth rate of both species was significantly greater for...
Food of blueback herring and threadfin shad in Jocassee Reservoir, South Carolina
Bruce M. Davis, Jeffrey W. Foltz
1991, Transactions of the American Fisheries Society (120) 605-613
Threadfin shad Dorosoma petenense and blueback herring Alosa aestivalis were introduced into Jocassee Reservoir, South Carolina, in the early 1970s as prey for large piscivores. To assess the potential for trophic competition between these clupeids, we examined their diets and the extent of diet overlap in May, August, and December 1982 and February 1983....

Ronald W. Griffiths, Donald W. Schloesser, Joseph H. Leach, William P. Kovalak
1991, Canadian Journal of Fisheries and Aquatic Sciences (48) 1381-1388
Dreissena polymorpha (Pallas), a small mussel common throughout most of Europe, was discovered in June of 1988 in the southern part of Lake St. Clair. Length–frequency analyses of populations from the Great Lakes and review of historical benthic studies suggest that the mussel was introduced into Lake St. Clair in late...
Roles of predation, food, and temperature in structuring the epilimnetic zooplankton populations in Lake Ontario, 1981-1986
Ora E. Johannsson, Robert O’Gorman
1991, Transactions of the American Fisheries Society (120) 193-208
We sampled phytoplankton, zooplankton, and alewives Alosa pseudoharengus and measured water temperature in Lake Ontario during 1981–1986. Through the use of general linear regression models we then sought evidence of control of the eplimnetic zooplankton community (mid-July to mid-October) by producers, consumers, and temperature. Our measures of the zooplankton community...
