Laboratory experiments on three species of fish to determine avoidance of Macondo oil

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.

本数据集报告了三种受试鱼类——帆鳍花鳉（Poecilia latipinna）、杂色鳉（Cyprinodon variegatus）与大鳍底鳉（Fundulus grandis）——之一对含油沉积物与无油沉积物的偏好性实验结果。含油沉积物经随机化处理，包含两类油样：风化油（重量占比40%）与新鲜原油，并设置了三级浓度梯度：低浓度（0.25毫升油/升）、中浓度（0.5毫升油/升）、高浓度（1.0毫升油/升）。实验对受试鱼类开展了10分钟的行为监测，统计其在水族箱含油区域与无油区域的停留时间占比，相关数据收录于"Behavioral Data"标签页。沉积物烃类（烷烃与芳香烃）样本取自各处理组的一个随机水族箱，相关分析结果收录于"Sediment Hydrocarbon Analyses"标签页。
