The unusual occurrence of elevated levels of odd chain length fatty acids (OCFA) in smelt taken during winter months in Jeddore Harbour, Nova Scotia, is due to the dietary intake of large numbers of the amphipod Pontoporeia femorata (Kröyer). Sampling over two winters confirms that the seasonal peak period for this amphipod in stomachs is mid-December to the end of February. The distributions of monoethylenic isomers are compared to distinguish exogenous and endogenous smelt dietary features in terms of the geographically limited phenomenon of high OCFA levels and the essential absence of biological activity for these acids.
新斯科舍省杰多雷港冬季捕获的胡瓜鱼体内奇数链长脂肪酸（OCFA）水平异常升高，是由于大量摄食了双壳纲动物股窗蟹（Kröyer）。连续两个冬季的采样证实，这种双壳纲动物在胡瓜鱼胃中的季节性高峰期为12月中旬至2月底。通过比较单烯异构体的分布，根据高OCFA水平这一地理上有限的现象以及这些酸基本不存在生物活性，来区分胡瓜鱼饮食中外源和内源特征。
