    Abstract The effects of various water chemistry parameters on the toxicity of copper to larval fathead minnows were investigated. Increased pH, hardness, sodium, dissolved organic matter, and suspended solids each caused toxicity to decrease on the basis of total copper concentrations. In contrast, added potassium resulted in increased toxicity. The fathead minnow (Pimephales promelas) is a species of temperate freshwater fish belonging to the genus Pimephales of the cyprinid family. The natural geographic range extends throughout much of North America, from central Canada south along the Rockies to Texas, and east to Virginia and the Northeastern United States. This minnow has also been introduced to many other areas via bait .

The species upon which most of the work on dissolved oxygen and turbidity we describe is based on the fathead minnow (Pimephales promelas) as prey and the yellow perch (Perca flavescens) as r work (Robb & Abrahams ) has demonstrated that fathead minnows are considerably more tolerant of hypoxic environments than their predator (figure 5).

In this study we conditioned fathead minnows (Pimephales promelas) to recognize the odor of a perch (Perca flavescens) by exposing them to perch odor coupled with minnow alarm cue.

We then staged encounters between the predator and prey in order to assess whether the predator odor training had any effect on survival of the prey. We tested for a survival effect in the presence and absence of.

Fathead minnow population characteristics and growth. Density estimates of juvenile (20–40 mm TL) and adult (>40 mm TL) fathead minnows were obtained using square 1‐m 2 pop nets (Dewey et al.

The present study determined the effects of environmentally relevant, short‐term (4‐h) exposure to the pyrethroid insecticide esfenvalerate on mortality, food consumption, growth, swimming ability, and predation risk in larvae of the fathead minnow (Pimephales promelas).Acute effect concentrations were determined, and in subsequent experiments, fish were exposed to the following measured.

Female fathead minnows (Pimephales promelas) exposed to copper (Cu) maternally transfer Cu tolerance to their larval offspring. Larvae produced after female parents received a sublethal 5-d, µg/L Cu exposure had significantly greater survivorship in potentially lethal Cu solutions than larvae produced before those females were exposed to Cu.

We showed that fathead minnows, Pimephales promelas Rafinesque,exposed to chemical cues from virile crayfish, Orconectes virilis (Hagen, ), foraging on minnow embryos hatch sooner than those exposed to a blank control.

Moreover, in the presence of cues from virile crayfish feeding on minnow embryos, the hatchlings exhibited a change. Previous studies of toxicant effects on fish foraging behavior and predator-prey interactions have taken a strictly empirical approach.

The most common observation of altered feeding behavior was cessation of feeding or reduction in the amount of artificial food consumed.

Changes in the number of live prey attacked and captured, latency to feed, and capture efficiency have also been documented. fish, such as fathead minnows, as well as early hatching of eggs, smaller fry (newly hatched fish) and increased incidence of abnor-malities and reduced survival in the fry (Taub, ).

Excerpt from: Short-term Methods for Estimating the Chronic Toxicity of Effluents and Receiving Waters to Freshwater Organisms. 4th edition () EPARWe examined effects of dietary methylmercury (MeHg) on reproduction of fathead minnows (Pimephales promelas). Juvenile fish were fed one of four diets until sexual maturity (phase 1): a control diet ( μg Hg g-1 dry weight) and three diets contaminated with MeHg at (low), (medium), and μg Hg g-1 dry weight (high).

At sexual maturity, male and female fish were paired, again.
