Growth and condition of bluegills in Wisconsin lakes: Effects of population density and lake pH Growth and condition of bluegills in Wisconsin lakes: Effects of population density and lake pH
Growth and condition of bluegills Lepomis macrochirus from five acidic lakes (pH 5.1–6.0) and six circumueutral lakes (pH 6.7–7.5) in northern Wisconsin were compared. Although mean condition factors and mean back‐calculated total lengths at ages 1 to 4 varied significantly among lakes, the differences were not related to lake pH. Rather, the ranks of mean condition factors and back...

Degradation of phenolic contaminants in ground water by anaerobic bacteria: St. Louis Park, Minnesota Degradation of phenolic contaminants in ground water by anaerobic bacteria: St. Louis Park, Minnesota
Coal-tar derivatives from a coal-tar distillation and wood-treating plant that operated from 1918 to 1972 at St. Louis Park, Minnesota contaminated the near-surface ground water. Solutions of phenolic compounds and a water-immiscible mixture of polynuclear aromatic compounds accumulated in wetlands near the plant site and entered the aquifer. The concentration of phenolic compounds in...

Effects of an aquatic plant and suspended clay on the activity of fish toxicants Effects of an aquatic plant and suspended clay on the activity of fish toxicants
Rotenone, antimycin, permethrin, pydrin, and Salicylanilide I were tested for their toxicities against fathead minnows (Pimephales promelas) in the presence of Canadian waterweed (Elodea canadensis) or suspended clay. The plants had little effect on the activity of rotenone and antimycin but substantially reduced the activity of permethrin and pydrin (synthetic pyrethroids). Bentonite...

Acute and chronic toxicity studies with monochlorobenzene in rainbow trout Acute and chronic toxicity studies with monochlorobenzene in rainbow trout
The toxicity of monochlorobenzene (CB) was investigated in rainbow trout following acute intraperitoneal (i.p.) administration and chronic exposure via the water in a continuously flowing system for 15 or 30 days. In the acute study overt toxicity and hepatotoxicity were monitored over a 96-h time period. Variables measured to assess toxicity included weight changes, liver weight to body...

Accumulation and loss of 2' ,5-dichloro-4'-nitrosalicylanilide (Bayer 73) by fish: laboratory studies Accumulation and loss of 2' ,5-dichloro-4'-nitrosalicylanilide (Bayer 73) by fish: laboratory studies
Residues of the 2-aminoethanol salt of 2',5-dichloro-4'-nitrosalicylanilide (Bayer 73), as determined by gas-liquid chromatography, were rapidly accumulated by fish exposed to the lampricide -in blood plasma, gallbladder bile, and muscle tissue of coho salmon (Oncorhynchus kisutch) and rainbow trout (Salmo gairdneri), and in bile and muscle of channel catfish (Ictalurus punctatus) and...

Appraisal of the Pelican River sand-plain aquifer, western Minnesota Appraisal of the Pelican River sand-plain aquifer, western Minnesota
The Pelican River sand-plain area includes approximately 200 square miles of outwash deposits in parts of Decker, Otter Tail, and Clay Counties in west-central Minnesota. Saturated thickness of the outwash is as much as 140 feet and yields of properly constructed wells locally may exceed 1,200 gallons per minute. Recharge to the outwash from snowmelt and rain ranged from 3.2 to 6.1...
