Evaluation of effects caused by high copper concentrations in Torch Lake, Michigan, on reproduction of yellow perch Evaluation of effects caused by high copper concentrations in Torch Lake, Michigan, on reproduction of yellow perch
Elevated concentrations of copper are present in Torch Lake, Michigan, an Environmental Protection Agency Superfund site. The sauger (Stizostedion canadense) population in Torch Lake has been extirpated and walleye (Stizostedion vitreum) populations are maintained by stocking. We used yellow perch (Perca flavescens) to determine if chronic exposure to elevated copper concentrations has...

Hepatic cadmium, metal-binding proteins and bioaccumulation in bluegills exposed to aqueous cadmium Hepatic cadmium, metal-binding proteins and bioaccumulation in bluegills exposed to aqueous cadmium
We examined sublethal responses of juvenile bluegills Lepomis macrochirus to aqueous cadmium in two 28-d tests (test I, 0.0-8.4 μg Cd per liter; test II, 0.0-32.3 μg Cd per liter) in an intermittent-flow diluter. The experimental design was completely randomized, with two replicates in each of eight treatments (seven Cd exposures and one water control with 25 fish per replicate). Cadmium...

Cadmium, metal-binding proteins, and growth in bluegill (Lepomis macrochirus Cadmium, metal-binding proteins, and growth in bluegill (Lepomis macrochirus
We exposed juvenile bluegill (Lepomis macrochirus) to ~1000 mg∙L−1 of continuously suspended river sediment in a 28-d test with six treatments (randomized block with one sediment-free control and five sediments ranging from 1.3 to 21.4 μg Cd∙g dry weight−1). Each treatment had three replicates, each with 25 fish. Growth was reduced by exposure to suspended sediment, probably due to...
