Detectable effect size and bioassay power of mummichog (Fundulus heteroclitus) and fathead minnow (Pimephales promelas) adult reproductive tests

Although multiple reproductive tests have been developed in small-bodied fish to determine the effects of endocrine-disrupting substances, few direct comparisons have been made among the available tests. Side-by-side reproductive tests with mummichog (Fundulus heteroclitus) and fathead minnow (FHM; Pimephales promelas) were conducted with 0, 3, 10, and 30% effluent from a bleached kraft pulp mill in Saint John, New Brunswick, Canada.
