Atrazine reduces reproduction in fathead minnow (Pimephales promelas).

Oxygen flux as an indicator of physiological stress in fathead minnow (Pimephales promelas) embryos: a real-time biomonitoring system of water quality.

The detection of harmful chemicals and biological agents in real time is a critical need for protecting freshwater ecosystems. We studied the real-time effects of five environmental contaminants with differing modes of action (atrazine, cadmium chloride, pentachlorophenol, malathion, and potassium cyanide) on respiratory oxygen consumption in 2-day postfertilization fathead minnow (Pimephales p...

Chronic Toxicity of Di-n-butyl and Di-n-octyl Phthalate to Daphnia Magna and the Fathead Minnow

The toxicities of di-n-butyl phthalate (DBP) and di-n-octyl phthalate (DOP) were assessed by measuring the effect of exposure to these compounds on the fecundity of Daphnia magna and on the hatching and survival of the early life stages of the fathead minnow Pimephales promelas. For D. magna, exposure to 1.8 mg/L DBP or 1.0 mg/L DOP caused a significant reduction in reproduction. Doses of 0.56 ...

EFFECTS OF SERTRALINE EXPOSURE ON FATHEAD MINNOW (Pimephales promelas) STEROIDOGENESIS Dennis R. Carty Thesis Prepared for the Degree of MASTER OF SCIENCE UNIVERSITY OF NORTH TEXAS December 2014 Carty, Dennis R. Effects of Sertraline Exposure on Fathead Minnow (Pimephales

Modeling impacts on populations: fathead minnow (Pimephales promelas) exposure to the endocrine disruptor 17beta-trenbolone as a case study.

Evaluation of population-level impacts is critical to credible ecological risk assessments. In this study, a predictive model was developed to translate changes in fecundity of the fathead minnow (Pimephales promelas) in a short-term laboratory toxicity test to alterations in population growth rate. The model uniquely combines a Leslie population projection matrix and the logistic equation. App...

The Toxicity of the Hydrolysis and Breakdown Products of Malathion to the Fathead Minnow (pimephales Promelas, Rafinesque)*

Abstract Malathion undergoes hydrolysis in aqueous solutions; the products derived from the reaction are dependent upon the pH of the medium. It was the purpose of this investigation to evaluate the toxicity of the products of malathion hydrolysis in the fathead minnow, Pimephales promelas. The studies were conducted by toxicity bioassays of 96 hr duration and continuous exposure tests of 14 da...
