Flow-through bioassay for measuring bioaccumulation of toxic substances from sediment Flow-through bioassay for measuring bioaccumulation of toxic substances from sediment
Over 10 million cubic meters of sediment are dredged annually from Great Lakes waterways. Because much of this material is taken from harbors, connecting channels, and other nearshore areas that often are contaminated with toxic substances, the sediments proposed for dredging need to be evaluated for the presence of bioavailable contaminants and the potential for toxicity to the biota...

Predation on lake whitefish eggs by longnose suckers Predation on lake whitefish eggs by longnose suckers
In November 1981, we observed intense predation on lake whitefish (Coregonus clupeaformis) eggs by longnose suckers (Catostomus catostomus) on lake whitefish spawning grounds in northwestern Lake Huron. Since longnose suckers commonly frequent the same habitat used by spawning lake whitefish, there exists the potential for high losses of eggs due to sucker predation.

Food of young-of-the-year lake trout (Salvelinus namaycush) in Presque Isle Harbor, Lake Superior Food of young-of-the-year lake trout (Salvelinus namaycush) in Presque Isle Harbor, Lake Superior
The food habits of young lake trout (Salvelinus namaycush) were studied by examining the digestive tracts of 293 young-of-the-year collected in Presque Isle Harbor, Lake Superior. Lake trout in the 25 to 27-mm length range started to eat food organisms before all of their yolk material was absorbed. Organisms consumed by the 25 to 27-mm young-of-the-year included Chironomidae, Copepoda

Water quality in the Gillham Lake-Cossatot River system during dry and wet periods Water quality in the Gillham Lake-Cossatot River system during dry and wet periods
Water samples were collected in the Cossatot River-Gillham Lake system during an extended dry period and after heavy rains to determine the spatial variations in certain water quality characteristics. Of particular interest was the influence of the reservoir discharge on the water quality of the tailwater compared with the effects of four tributaries entering the tailwater below the...

Potential impacts of water diversion on fishery resources in the Great Lakes Potential impacts of water diversion on fishery resources in the Great Lakes
Uses of Great Lakes water within the Great Lakes basin are steadily increasing, and critical water shortages elsewhere may add to the demands for diversions of water out of the basin in the near future. The impacts of such diversions on fish in the Great Lakes must be considered in the context of in-basin uses of the water, because in-basin uses already adversely affect the fishery...

Bioaccumulation of toxic substances associated with dredging and dredged material disposal: a literature review Bioaccumulation of toxic substances associated with dredging and dredged material disposal: a literature review
A literature review of sediment bioassessment was conducted as the first step in the development of a more standardized and ecologically sound test procedure for evaluating sediment quality. Based on the review, the authors concluded that 1) a standardized laboratory bioassessment test should consist of flowthrough exposure of at least 10 days duration using more than one aquatic...
