Investigation into three potential modifying factors in larval fathead minnow (Pimephales promelas) growth and survival
The responses of larval fish to toxicants in subchronic toxicity tests may be modified by events and stressors not associated with the toxicants themselves. In the following work, three potential modifying factors related to larval fish growth, survival, and response to toxicant stress were …

A Comparison of Olfactory Organ Development and Feeding Behavior in Larval Fathead Minnows, Pimephales promelas Rafinesque
The early recruitment and use of the chemoreceptive senses, olfaction and gustation, are important for early behavior development in fathead minnows and the ability of larvae to survive after hatching. Chemoreception is used in the location of food, avoidance of predators, and for intraspecific …

Effects of nanosilver and silver nitrate exposure on fathead minnows (Pimephales promelas) and zebrafish (Danio rerio)
… was to use two fish models, fathead minnows (Pimephales promelas; FHMs) and zebrafish ( Danio rerio; ZFs), to study the effects of AgNPs on gill histopathology, Na+/K+-ATPase immunoreactivity, mucus production, bioaccumulation, particle uptake characterization, gill gene expression, and …

The Effect of Acute Low pH on Feeding and Locomotor Activity of Larval Fathead Minnows, Pimephales promelas
Lowered pH conditions in aquatic environments can have a negative impact on many aquatic organisms. In fish it has been shown that acidic water conditions may result in altered gill morphology, reduced reproductive success, changes in locomotor and feeding behavior and even death. Juveniles and …

REPRODUCTION IN FATHEAD MINNOWS (PIMEPHALES PROMELAS) FOLLOWING WATER OR SEDIMENT EXPOSURE TO A COMPLEX URANIUM MILLING EFFLUENT ELEVATED IN SELENIUM
… and importance of each source to fathead minnow (Pimephales promelas) reproduction and survival. Identification of pathways of exposure is critical to the mitigation of any observed effects. Trios of fathead minnows were allocated to one of four treatments for 21-days where the following were …

Development of a three-trophic level toxicity test utilizing an alga (Chlorella vulgaris), rotifer (Brachinous calyciflorus), and fish (Pimephales promelas)
… rotifer (Brachionus calyciflorus), and fish (Pimephales promelas). The chemostat design used for the lower two trophic levels was crucial in being able to supply the top trophic level with sufficient food on a continuous basis. The system was initially evaluated using copper (Cu) and selenium …

Assessment of the Efficacy of a Constructed Wetland to Reduce or Remove Wastewater Effluent Estrogenicity and Toxicity Using Biomarkers in Male Fathead Minnows (Pimephales Promelas Rafinesque, 1820)
Vitellogenin in Pimephales promelas was used to assess estrogenicity of a local municipal effluent. Vitellogenin induction in male P. promelas increased in frequency and magnitude with increased exposure duration and was greater ("=0.05) than controls after 2 and 3 weeks of exposure. The level of …

Understanding environmental influences on bioaccumulation of contaminants of emerging concern among fish species.
… Next, I examined uptake of a mixture of PFAS by Pimephales promelas over 7 days, under laboratory conditions. I then identified significant relationships between different physicochemical properties and bioaccumulation, including the apparent volume of distribution, which shows promise for …

Toxicity of aliphatic amines on the embryos of zebrafish Danio rerio - experimental studies and QSAR
… other aquatic species such as the fathead minnow Pimephales promelas, Daphnia magna and Tetrahymena pyriformis showed that the toxicity of each species is a good predictor for each other.

Prymnesium parvum effects on green algae, cladocerans and fish in field and laboratory studies.
… and ecological impacts on a fish model, Pimephales promelas, a model green algae competitor, Pseudokirchinella subcapitata and a model cladoceran predator, Daphnia magna. Prymnesium parvum reduced D. magna survival and reproduction in laboratory and field studies, providing the first …

Food Habits and Growth of Rainbow Trout in a Prairie Pond
… (31.2%), corixids (7.0%), and fathead minnows (Pimephales promelas) (1.2%). Volumetrically, notonectids comprised 37.7% of the total volume of organisms, fathead minnows 16.8%, dipteran larvae 9.9%, and decapods 8.1%. Growth of the trout was better than in many areas of the country and was …

Pilot-scale study on anaerobic/aerobic treatment of a textile dye wastewater
… of the wastewaters to Ceriodaphnia dubia and Pimephales promelas were studied. In addition, the benefits of polymer treatment of anaerobic effluent, prior to aerobic treatment, were evaluated in a lab-scale system utilizing continuous flow biological reactors (CFBRs). Wastewater samples were …

Rainbow Trout Production and Water Quality in Eastern South Dakota Dugouts
… and feeding combination [fathead minnows (Pimephales promelas) and supplemental feed, supplmental feed, and trout alone]. Chemical physical properties were also monitored in an old and new unstocked dugouts from July 1980 to July 1981. Growth was greater for 988/ha rainbow trout than the …

The impact of carbon dioxide on freshwater fish behaviors
… CO2 on the behaviors of fathead minnows (Pimephales promelas) and silver carp (Hypophthalmichthys molitrix) following exposure to conspecific skin extracts (alarm cues). In fathead minnows, their response to conspecific skin extracts were significantly impaired following exposure to …

Growth, survival, and vulnerability to predation of stocked walleye (Stizostedion vitreum) fingerlings
… pike (Esox Lucius consumed fathead minnows (Pimephales promelas) 2.6 times more frequently than walleye (Stizostedion vitreum) and 5.7 times more than lepomids. Prey were more vulnerable in circular than rectangular tanks. In field studies, walleye fingerlings averaging 35 mm and 53 mm (mean …
