Plastic marine debris affects species on most trophic levels, including pelagic fish. While plastic debris ingestion has been investigated in planktivorous fish in the North Pacific Ocean, little knowledge exists on piscivorous fish. The objectives of this study were to determine the frequency of occurrence and the composition of ingested plastic marine debris in longnose lancetfish (Alepisaurus ferox), a piscivorous fish species captured in the Hawaii-based pelagic longline fishery. Nearly a quarter (47 of 192) of A. ferox sampled contained plastic marine debris, primarily in the form of plastic fragments (51.9%). No relationship existed between size (silhouette area) or amount of plastic marine debris ingested and morphometrics of A. ferox. Although A. ferox are not consumed by humans, they are common prey for fish commercially harvested for human consumption. Further research is needed to determine residence time of ingested plastic marine debris and behavior of toxins associated with plastic debris.
塑料海洋垃圾会影响到大多数营养级别的物种,包括远洋鱼类。虽然人们已经研究过北太平洋浮游鱼类吞食塑料碎片的情况,但对于肉食性鱼类却知之甚少。本研究的目的是确定在夏威夷延绳钓渔业中捕获的肉食性尖鼻狼牙鳝(Alepisaurus ferox)体内吞食塑料海洋垃圾的频率和组成。在所研究的 192 条尖鼻狼牙鳝中,近四分之一(47 条)体内含有塑料海洋垃圾,主要以塑料碎片的形式存在(51.9%)。尖鼻狼牙鳝吞食的塑料海洋垃圾的数量和种类与它们的形态特征(轮廓面积)之间没有关系。虽然尖鼻狼牙鳝人不吃,但它们是商业捕捞供人类食用鱼类的常见猎物。需要进一步研究来确定吞食的塑料海洋垃圾的停留时间以及与塑料碎片相关的毒素的行为。
