Selenium and other elements in juvenile striped bass from the San Joaquin Valley and San Francisco Estuary, California Selenium and other elements in juvenile striped bass from the San Joaquin Valley and San Francisco Estuary, California
Concentrations of selenium and other trace elements were determined in 55 whole body samples of juvenile anadromous striped bass (Morone saxatilis) from the San Joaquin Valley and San Francisco Estuary, California. The fish (≤1 yr old—the predominant life stage in the San Joaquin Valley) were collected in September–December 1986 from 19 sites in the Valley and 3 sites in the Estuary, and...

Behavioral indicators of sublethal toxicity in rainbow trout Behavioral indicators of sublethal toxicity in rainbow trout
Four measures of behavior-spontaneous swimming activity, swimming capacity, feeding behavior, and vulnerability to predation-were assessed as indicators of sublethal toxicity in rainbow trout (Oncorhynchus mykiss) in 96-hr exposures to sublethal concentrations of six agricultural chemicals: carbaryl, chlordane, dimethylamine salt of 2,4-dichlorophenoxyacetic acid (2,4-DMA), tributyl

Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams Automatic tracer-dilution method used for stage-discharge ratings and streamflow hydrographs on small Iowa streams
An automatic system was designed to concurrently measure stage and discharge for the purpose of developing stage-discharge ratings and high flow hydrographs on small streams. Stage, or gage height, is recorded by an analog-to-digital recorder and discharge is determined by the constant-rate tracer-dilution method The system measures flow above a base stage set by the user. To test the

Influence of ingested lead on body mass of wintering canvasbacks Influence of ingested lead on body mass of wintering canvasbacks
We determined the prevalence of lead shotgun pellets in gizzards of canvasbacks (Aythya valisineria) collected at Catahoula Lake and the Mississippi River Delta, Louisiana, during winter 1987-88 to assess the influence of ingested lead shot on canvasback body mass. The prevalence of ingested lead shot was significantly higher at Catahoula Lake (27%) than at the Mississippi River Delta (4...
