Toxicity of formalin, malachite green, and the mixture to four life stages of rainbow trout Toxicity of formalin, malachite green, and the mixture to four life stages of rainbow trout
Formalin, malachite green, or a mixture of them are utilized in fish culture for control of external parasites of fish and control of fungus on fish and fish eggs. Very little information is available concerning the toxicity of these compounds to fish under laboratory test conditions or the differences in sensitivity to these chemicals at various life stages. This study was designed to 1...

Hydrology and trout populations of cold-water rivers of Michigan and Wisconsin Hydrology and trout populations of cold-water rivers of Michigan and Wisconsin
Statistical multiple-regression analyses showed significant relationships between trout populations and hydrologic parameters. Parameters showing the higher levels of significance were temperature, hardness of water, percentage of gravel bottom, percentage of bottom vegetation, variability of streamflow, and discharge per unit drainage area. Trout populations increase with lower levels...

Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish
A procedure for the determination of 3-trifluormethyl-4-nitrophenol (TFM) in fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether; the extract is cleaned up by partitioning the TFM from the extracting solvent into 0.1N NaOH, acidifying the aqueous solution, and partitioning again with hexaneethyl ether. The TFM is methylated with diazomethane and analyzed...

Water resources of the Cannon River watershed, southeastern Minnesota Water resources of the Cannon River watershed, southeastern Minnesota
The 1,462 square miles of land surface in the Cannon River watershed varies considerably from areas of low hills and plains to areas dominated by streams deeply incised into bedrock. Much of the south-central part of the area consists of a till plain that ranges in altitude from 1,100 to 1,200 feet above mean sea level. This plain is bordered by end moraines that form ridges on the east...

Water resources of the Blue Earth River watershed, south-central Minnesota Water resources of the Blue Earth River watershed, south-central Minnesota
The Blue Earth River Watershed in Minnesota includes 3,106 square miles of land surface, which varies from fairly flat to gently rolling. The drainage extends south to include an additional 450 square miles in Iowa. The western, southern, and eastern boundaries are end moraines formed by Pleistocene glaciers. Major streams have eroded channels 40 to 75 feet deep in headwater regions and...

Water resources of Wisconsin: Lower Wisconsin River basin Water resources of Wisconsin: Lower Wisconsin River basin
This report describes the physical environment, availability, distribution, movement, quality, and use of water in the upper Wisconsin River basin as an aid in planning and water management. The report presents general information on the basin derived from data obtained from Federal, State, and local agencies, New field data were collected in areas where information was lacking. More...

Bedrock geologic map of the Greenwood quadrangle, Marquette County, Michigan Bedrock geologic map of the Greenwood quadrangle, Marquette County, Michigan
The Marquette Iron Range is presently ( 1973) the second largest iron mining district in the United States. Commercial iron deposits, now mostly concentrating-grade ore, are in the Negaunee Iron-formation, which is part of a thick sequence of metasedimentary rocks of Precambrian X age. These rocks are preserved in the west-trending Marquette synclinorium, and are flanked to the north and...
