Diane Waller, 20160715, Valuation of the biopesticide Zequanox® on reproduction and early development of Fathead minnow (Pimephales promelas): Data: U.S. Geological Survey data release,


The goal of the study in which the data were collected to determine the non-target effects of the molluscicide Zequanox on the survival and reproductive success of Fathead minnows in simulated open-water applications. The specific objectives were to evaluate effects of 8-h exposure to 50 mg/L and 100 mg/L AI Zequanox on: 1) survival of adult Fathead minnows, 2) egg deposition, 3) hatchability of eggs, and 4) survival and growth of newly hatched fry.

There are no published studies on the toxicity of Zequanox to fish in static exposures at the maximum approved open-water label concentration (100 mg/L) and exposure duration (8h). Previous trials on fish used juvenile/fingerling life stages. Data are lacking on the safety of Zequanox to spawning adults, eggs and early life stages of fish. Results can be used by fisheries managers to determine the safety of Zequanox as a tool for eliminating dreissenid mussels during aquaculture and restoration activities.
