Eurasian otter feeding trial

This are data from a fish feeding trial on Eurasian Otters. The animals were fed a different fish species every day; 5 otter spraints were collected per evening; these were analyzed molecularely for fish DNA and morphologically for fishbones.本数据集源自针对欧亚水獭的鱼类饲喂试验。试验期间每日为受试水獭投喂不同鱼种；每晚收集5份水獭粪（otter spraints），采用分子生物学方法检测样本中的鱼类DNA，并通过形态学方法分析其所含鱼骨。
