Microplastics pollution is a growing global concern that affects all aquatic ecosystems. Microplastics in the environment can be in the form of fibers and/or particles, being the former the most abundant in the marine environment, representing up to 95% of total plastics. The aim of this work was to compare the content of microplastics among intertidal fish with different feeding type. Our results show that omnivorous fish presented a higher amount of microplastic fibers than registered in herbivores and carnivores. Moreover, lower condition factors (K) were found in omnivorous specimens with higher microplastic content. We hypothesized that the type of feeding resulted in different microplastic ingestion, with species with wider range of food sources as omnivores with higher rates. Futures studies carried out to evaluate the biological impacts of microplastics on marine organisms, and microplastics cycling on the marine environment should consider the type of feeding of the studied species.
微塑料污染是一个日益引起全球关注的问题，影响着所有水生生态系统。环境中的微塑料可以呈纤维和/或颗粒的形式，前者在海洋环境中最为丰富，占塑料总量的95%。这项工作的目的是比较不同食性的潮间带鱼类体内微塑料的含量。我们的结果表明，杂食性鱼类体内的微塑料纤维含量高于草食性和肉食性鱼类。此外，微塑料含量较高的杂食性样本的状况因子（K）较低。我们推测，食性类型导致了不同的微塑料摄入量，食物来源范围更广的物种（如杂食性动物）摄入量更高。未来评估微塑料对海洋生物的生物学影响以及微塑料在海洋环境中的循环的研究应考虑所研究物种的食性类型。
