In vitro model of the fathead minnow hypothalamic-pituitary-gonadal axis for toxicological evaluation
… were to develop a tissue co-culture of the fathead minnow (Pimphales promelas) HPG axis and liver to serve as an in vitro system that reproduces the interaction of the fathead minnow HPG axis in vivo. This model system was tested by evaluating the effects of a known EDC, trenbolone acetate …

Investigation into three potential modifying factors in larval fathead minnow (Pimephales promelas) growth and survival
… than 44 mg MB/L in 24 h. At the suggested fathead minnow culture temperature, 25°C, concentrations greater than 5.0 ppm were acutely toxic in 96 h. Chronic toxicity, determined at 25°C, was found at levels greater than 2.12 mg MB/L. Light intensity negatively affected MB chronic toxicity. …

The fathead minnow embryo as a model for the development of alternative testing methods in ecotoxicology.
The fathead minnow, Pimephales promelas, a small cyprinid from North America, is widely used as laboratory test fish. In the present study, rearing and breeding conditions for the fat-head minnow were optimized in our laboratory to produce eggs on a regular basis for testing. Firstly, these eggs …

The toxic effects of the pesticide lindane on the early developmental stages of the fathead minnow
… on the eggs, yolksac fry and larvae of the fathead minnow (Pimephales promelas) were investigated over 14 days at 25 and 18°C. The general objective was to understand the effects of the pesticide on the early life stages of the fish, and to evaluate the suitability of these stages as …

Development of methodology for community level toxicity testing using the fathead minnow seven day survival-growth impairment test
… of the food source currently used in the fathead minnow survival-growth impairment test (<i>Artemia</i>) with a freshwater food source (the rotiter, <i>Brachionus calyciflorus</i>). Along with the alga <i>Chlorella vulgaris</i> (producer), B. calyciflorus (primary consumer) and the fathead …

Food Habits and Consumption Estimates of Walleyes Stocked as a Tool to Suppress Fathead Minnow Populations in West-Central Minnesota Wetlands
… waterfowl. However, persistent, highly abundant fathead minnow Pimephales promelas populations often prevent this clear-water state from occurring. The presence of fathead minnows has detrimental effects on macroinvertebrates, zooplankton, water clarity, and thus macrophytes and epiphyton. …

Quantitative structure-activity relationships of comparative toxicity to aquatic organisms.
… phospherum (known as the Microtox test), and the fathead minnow. To model the toxicities 49 physico-chemical and structural parameters were produced including measures of hydrophobicity, molecular size and electronic effects from techniques such as computational chemistry and the use of molecular …

Survival and growth of fish in water reclaimed from cattle feedlots
… channel catfish (Ictalurus punctatus), fathead minnow (Pimephales promelas), redfin shiner (Notropis umbratilis). tilapia (Tilapia aurea), sailfin molly Poecilia latipinna), and platies (Xiphophorus maculatas) were evaluated in 2-week trials (10 fish/ trial). It was concluded that it is …

The effects of dietary selenomethionine on the escape behaviours of Fathead Minnows
… diet on the escape behaviours of the Fathead Minnow. Using kinematic analysis, I observed how fish responded to various looming threats. I exposed fish to sub-chronic periods of environmentally relevant concentrations of selenium in the form of selenomethionine-spiked diets. I achieved …

Quantifying the U.S. Coast Guard Ecological Risk Assessment on Diluted Bitumen
… and weathering data from NRCan and preliminary Fathead Minnow (Pimephales promelas) toxicity data from INRS, exposure and stressor-response profiles to DB are created. The ecological risk of Fathead Minnow exposure to DB spills is characterized and compared to the risks associated with CC oil …

Pathogenic mechanisms of Photobacterium damselae subspecies piscicida in hybrid striped bass
… carpio (EPC), channel catfish ovary (CCO), and fathead minnow (FHM) cells lines was also evaluated using an in vitro invasion assay. All three cell lines were susceptible to invasion and supported replication of P. damselae. Fathead minnow cells were more susceptible to invasion than the other …

Towards an understanding of synthetic glucocorticoid hazards in aquatic systems.
… zebrafish (Danio rerio) model in vitro and the fathead minnow (Pimephales promelas) model in vivo. Lastly, I examined the effects of synthetic glucocorticoid exposure on aquatic species by utilizing the adverse outcome pathway framework. I observed the inhibition of fin regeneration following …

Toxicity of aliphatic amines on the embryos of zebrafish Danio rerio - experimental studies and QSAR
… models for 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.

Evaluation of Largemouth Bass and Bluegill Stocking Strategies in South Dakota Ponds
… a high-density, split-stocked pond. Bluegill and fathead minnow (Pimephales promelas) reproduction was documented in the majority of split-stocking treatment ponds in 1984 and 1985. No bluegill reproduction was reported in the simultaneous-stocking treatment in 1985. Bluegill fry abundance was …

The Influence of Livestock Watering Ponds (Dugouts) on Native Stream Fishes, Especially the Endangered Topeka Shiner (Notropis topeka)
… sunfish, green sunfish, and total sunfish), fathead minnow (Pimephales promelas) abundance, and fathead minnow presence. Fish assemblages of dugouts (22 species) and the stream (20 species) were similar. Fish inhabited 13 of 20 dugouts; seven of 20 contained Topeka shiners. Three dugouts …

The impact of carbon dioxide on freshwater fish behaviors
… the effects of elevated 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 …

Growth and Survival of Largemouth Bass in Newly Stocked South Dakota Impoundments
… included gold shiners (Notemigonus crysoleucas), fathead minnow (Pimephales promelas), black bullhead (Ictalurus melas), and bluegill (Lepomis macrochirus). Bass only stocking was also evaluated. First eyar survival values for 16 eastern South Dakota ponds ranged from 1 to 100%, with a mean of …

Daphnia Diel Vertical Migration and Chemical Cues from Fish Predators
… osseus (longnose gar), and Pimephales promelas (fathead minnow). Light had a significant effect on lowering Daphnia position in the last set of trials and limited data suggest this light effect was limited to columns containing water from bluegill sunfish and minnows. Although the results of this …
