Interactive Toxicity of Aluminum and Acidity to Early Life Stages of Brook Trout
Abstract The influences of exposure to aluminum and increased acidity on mortality, growth, behavior, and biochemical responses of brook trout Salvelinus fontinalis were evaluated as a function ofExpand

Role of physical barriers in the control of sea lamprey (Petromyzon marinus)
Mechanical and electromechanical barriers played a significant role in the initial attempts to control sea lamprey (Petromyzon marinus) populations in the upper Great Lakes. More recentlyExpand

Toxicity of sodium selenite to rainbow trout fry
In a study designed to examine the long-term effects of inorganic selenium (IV) on early life stages of rainbow trout (Salmo gairdneri), survival was significantly reduced at selenium concentrationsExpand

Sensitivity of Young Striped Bass to Organic and Inorganic Contaminants in Fresh and Saline Waters
Abstract The toxicity to young striped bass Morone saxatilis of a contaminant mixture composed of organic and inorganic chemicals was determined in fresh and saline waters when the fish were 35–80 dExpand

Role of calcium in gill function in freshwater fishes
Abstract 1. 1. The role of external Ca on the ionic and osmoregulatory function of the gills of freshwater fishes has been reviewed. 2. 2. A competition for binding sites on the gill between Ca andExpand

Sensitivity of brook trout to low pH, low and elevated aluminum concentrations during laboratory pulse exposures
Yolk-sac larvae of brook trout (Salvelinus fontinalis) were exposed to four sequential low pH and calcium (Ca) pulses, nominally ranging from pH 6.5 to 4.0 in 0.5 pH unit increments, with and withoutExpand

Influence of pH and aluminum on developing brook trout in a low calcium water.
Eyed embryos of brook trout (Salvelinus fontinalis) were exposed to nominal pHs of 4.5, 5.5 and 7.5 with and without aluminum (300 microg liter(-1)) in extremely soft water (hardness <9mg liter (-1))Expand

Influence of Sampling on the Blood Chemistry of Atlantic Salmon
Abstract Blood samples were taken from laboratory-reared Atlantic salmon (Salmo salar) to determine the physiological status of the fish. The Atlantic salmon were also subjected to one of eightExpand

Biomonitoring of lead-contaminated Missouri streams with an assay for erythrocyte δ-aminolevulinic acid dehydratase activity in fish blood
The activity of the enzyme δ-aminolevulinic acid dehydratase (ALA-D) in erythrocytes has long been used as a biomarker of lead exposure in humans and waterfowl and, more recently, in fishes. TheExpand
