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.本数据集记录了3种供试鱼类（帆鳍花鳉（Poecilia latipinna）、盐生谷鳉（Cyprinodon variegatus）、大鳍底鳉（Fundulus grandis））中的任意一种对油污沉积物与未油污沉积物的偏好性实验数据。油污沉积物的制备采用随机分组方案，所用油类涵盖风化油（占沉积物重量的40%）与新鲜原油，浓度设置为低、中、高三个梯度，分别为0.25 mL油/L、0.5 mL油/L及1.0 mL油/L。实验期间对供试鱼类开展10分钟的行为观测，统计其在水族箱油污区域与无油区域的停留时间占比，相关数据详见"Behavioral Data（行为数据）"标签页。从各处理组中随机选取一个水族箱采集沉积物样本，进行烃类（烷烃与芳香烃）成分分析，相关结果详见"Sediment Hydrocarbon Analyses（沉积物烃类分析）"标签页。
