Registro de micro y mesoplásticos en el tracto digestivo de la especie vulnerable Olivaichthys cuyanus (Siluriformes: Diplomystidae), en el río cordillerano Los Patos, San Juan, Argentina.

The presence of micro and meso-plastics in the stomach and intestine of specimens of otuno catfish (Olivaichthys cuyanus) from Los Patos River is documented for the first time in Barreal, a locality in the Province of San Juan, in the arid west of Argentina. These elements are potentially harmful for the species' survival, and can generate effects such as death due to strangulation and starvation or inflammation and tissue contamination. This record evidences bad management of waste of anthropic origin. [ABSTRACT FROM AUTHOR]
