摘要

摘要:本文首次报道了新热带鱼对塑料的摄食。对在厄瓜多尔拉塞瓜湿地采集的20只标本(雄、雌各10只)胃内容物进行了目测评估。塑料的出现频率(FO)为50%，塑料负荷(PL)在每人5至55个颗粒之间。97%的塑料颗粒是微塑料(0.05)。鱼的大小与PL之间无显著相关(>.05)。纤维是最常观察到的类别，透明和蓝色是最丰富的。研究结果表明，拉塞瓜湿地水域的高水平塑料污染可能对生态系统和依赖它的人们构成威胁。

Ingestion of Plastics in a Wild Population of the Pacific Fat Sleeper (Dormitator latifrons)

Abstract: This is the first report of plastics ingestion by the neotropical fish Dormitator latifrons. The stomach contents of 20 specimens (10 males and 10 females) collected in La Segua wetland (Ecuador) were assessed visually. Frequency of occurrence (FO) of plastics was 50% and the plastic load (PL) was between 5 and 55 particles per individual. Ninety-seven percent of plastic particles found were microplastics (<5.0 mm), and 3% were larger. No significant differences were found in PL between females and males (>0.05). No significant correlation was found between fish size and PL (>0.05). Fibers were the most frequently observed category, and transparent and blue colors were the most abundant. The results suggest high levels of plastic pollution in waters of La Segua wetland that may represent a threat to both the ecosystem and the people who rely on it.

期刊介绍： Pacific Science: A Quarterly Devoted to the Biological and Physical Sciences of the Pacific Region The official journal of the Pacific Science Association. Appearing quarterly since 1947, Pacific Science is an international, multidisciplinary journal reporting research on the biological and physical sciences of the Pacific basin. It focuses on biogeography, ecology, evolution, geology and volcanology, oceanography, paleontology, and systematics. In addition to publishing original research, the journal features review articles providing a synthesis of current knowledge.
