Data herein reports on the preferences of one of three species of fish (Poecilia latipinna, Cyprinodon variegatus, or Fundulus grandis) for oiled versus unoiled sediment. Oiled sediments were randomized and included weathered (40% by weight) or fresh oil at a range of concentrations (low: 0.25 mL oil/L, medium: 0.5 mL oil/L, or high: 1.0 mL oil/L). Fishes were recorded for a period of 10 minutes and the proportion of time spent in oil and no oil sections of the tank recorded and reported in the 'Behavioral Data' tab. Sediment hydrocarbon (alkane and aromatics) were taken from one randomized tank from each treatment and is reported in the 'Sediment Hydrocarbon Analyses' tab.

By giving organisms a choice between oil-contaminated and clean sediments, this work is integral in determining if fishes have the capacity to detect and avoid oil. Results are critical to understanding the resiliency of marsh organisms to anthropogenic disasters such as oil spills and are essential for the continued successful management of living, motile resources such as marsh nekton.
