Management briefs: Phototaxis of larval and juvenile northern pike Management briefs: Phototaxis of larval and juvenile northern pike
Age-0 northern pike Esox lucius prefer vegetated habitats that are difficult to sample with standard towed gears. Light traps can be effective for sampling larval fishes in dense vegetation, given positive phototaxis offish. We evaluated the phototactic response of young northern pike by comparing the catches of larvae and juveniles obtained with plexiglass traps deployed with a chemical...

Presence and distribution of nitrate and selected pesticides in surficial-sand aquifers and selected lakes, 1993-94, East Otter Tail County, Minnesota Presence and distribution of nitrate and selected pesticides in surficial-sand aquifers and selected lakes, 1993-94, East Otter Tail County, Minnesota
This report presents selected data collected during the first year (December 1993 to September 1994) of a three year water-quality study of surficial-sand aquifers and selected lakes in east Otter Tail County, Minnesota. The objectives of the study are (1) to determine the presence and distribution of nitrate-nitrogen and selected pesticides in ground water from the surficial-sand...

Hydrology and relation of selected water-quality constituents to selected physical factors in Dakota County, Minnesota, 1990-91 Hydrology and relation of selected water-quality constituents to selected physical factors in Dakota County, Minnesota, 1990-91
Selected water-quality constituents were determined in water from 5 surface-water sites and 29 wells in Dakota County, Minnesota, to search for possible relations to selected physical factors, including waste-water discharge, agricultural land, Quaternary deposits, bedrock, soil-leaching potential, and water-table depth. All surface-water samples were from the Vermillion River Basin...

Water resources of the Grand Portage Indian Reservation, northeastern Minnesota Water resources of the Grand Portage Indian Reservation, northeastern Minnesota
The Grand Portage Indian Reservation Tribal Council needs information about the availability and quality of the ground water in the Reservation to develop, protect, and manage this resource for future use. The U.S. Geological Survey, in cooperation with the Grand Portage Indian Reservation Tribal Council, did a three-year study of the ground water in the Reservation to provide this...

Responses of bluegills and black crappies to dissolved oxygen, temperature, and current in backwater lakes of the upper Mississippi River during winter Responses of bluegills and black crappies to dissolved oxygen, temperature, and current in backwater lakes of the upper Mississippi River during winter
We conducted a radiotelemetry study to examine the effects of dissolved oxygen (DO), water temperature, and current velocity on winter habitat selection by bluegills Lepomis macrochirus and black crappies Pomoxis nigromaculatus in the Finger Lakes backwater complex, Pool 5, on the upper Mississippi River. When DO was above 2 mg/L, both species selected areas with water temperature...

Improving electrofishing catch consistency by standardizing power Improving electrofishing catch consistency by standardizing power
The electrical output of electrofishing equipment is commonly standardized by using either constant voltage or constant amperage, However, simplified circuit and wave theories of electricity suggest that standardization of power (wattage) available for transfer from water to fish may be critical for effective standardization of electrofishing. Electrofishing with standardized power...

Ichthyoplankton abundance and variance in a large river system concerns for long-term monitoring Ichthyoplankton abundance and variance in a large river system concerns for long-term monitoring
System-wide spatial patterns of ichthyoplankton abundance and variability were assessed in the upper Mississippi and lower Illinois rivers to address the experimental design and statistical confidence in density estimates. Ichthyoplankton was sampled from June to August 1989 in primary milieus (vegetated and non-vegated backwaters and impounded areas, main channels and main channel...
