The role of color in the intake of microplastic fragments by zebrafish (Danio rerio)El papel del color en la ingesta de fragmentos de microplástico por el pez cebra (Danio rerio)Ríos, Juan Manuelevitaciónmicroplásticospreferenciapeces de agua dulceavoidancemicroplasticspreferencefreshwater fishThe presence of microplastics (MPs) in the stomach contents of freshwater fish has been globally reported. However, the mechanisms underlying the consumption of MPs by aquatic biota are still unclear. In this study, the fundamental question of why wild freshwater fish ingest plastic was investigated. The intake of MPs due to confusion by fish with their natural prey, such as plankton, is a hypothesis that has gained importance lately. Therefore, the color of MPs could influence their consumption, especially in visual predators. In order to evaluate the intake of MP fragments according to the color (red, green, yellow, white, black and blue), a multiple-choice experiment was performed in the laboratory using the zebrafish (Danio rerio) as test species. The results indicated that the zebrafish preferred to ingest blue fragments, while avoiding green and white fragments when faced with an equitable supply of different-colored MPs. Although it is not yet clear how the color of the plastic is related to selectivity and consumption in freshwater fish, the visual skills of the fish could help to explain why certain colors are attractive to a particular fish species.Se ha reportado la presencia de microplásticos (MP) en el contenido estomacal de peces de agua dulce a nivel global. Sin embargo, los mecanismos subyacentes al consumo de MP por parte de los animales acuáticos aún no están claros. En este estudio se investigó la pregunta fundamental de por qué los peces silvestres de agua dulce ingieren plástico. La ingesta de MP debida a la confusión por parte de los peces con sus presas naturales, tales como el plancton, es una hipótesis que ha cobrado importancia últimamente. Por lo tanto, el color del MP podría influenciar su consumo, especialmente en depredadores visuales. Con el objetivo de evaluar la ingesta de fragmentos de MP según el color (rojo, verde, amarillo, blanco, negro y azul), se llevó a cabo un experimento de opción múltiple en el laboratorio utilizando al pez cebra (Danio rerio) como modelo de estudio. Los resultados indicaron que frente a una oferta de igual proporción de MP de distintos colores, el pez cebra prefirió consumir los fragmentos de color azul, mientras que evitó consumir los verdes y los blancos. Aunque todavía no está claro en qué forma se relaciona la coloración del plástico con la selectividad y consumo en peces de agua dulce, las habilidades visuales de los peces podrían explicar por qué ciertos colores son atractivos para una especie de pez en particular.Instituto de Ciencias de la Atmósfera, Universidad Nacional Autónoma de México2022-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionARTtext/htmlapplication/pdfhttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/5452310.20937/RICA.54523Revista Internacional de Contaminación Ambiental; Vol. 38 (2022); 551-560Revista Internacional de Contaminación Ambiental; Vol. 38 (2022); 551-5600188-4999reponame:Revista Internacional de Contaminación Ambientalinstname:UNIVERSIDAD NACIONAL AUTÓNOMA DE MÉXICOinstacron:UNAMspahttps://www.revistascca.unam.mx/rica/index.php/rica/article/view/54523/47318https://www.revistascca.unam.mx/rica/index.php/rica/article/view/54523/47193Derechos de autor 2022 Revista Internacional de Contaminación Ambientalhttps://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessoai:ojs.pkp.sfu.ca:article/545232024-08-16T19:00:41Z |

The presence of microplastics (MPs) in the stomach contents of freshwater fish has been globally reported. However, the mechanisms underlying the consumption of MPs by aquatic biota are still unclear. In this study, the fundamental question of why wild freshwater fish ingest plastic was investigated. The intake of MPs due to confusion by fish with their natural prey, such as plankton, is a hypothesis that has gained importance lately. Therefore, the color of MPs could influence their consumption, especially in visual predators. In order to evaluate the intake of MP fragments according to the color (red, green, yellow, white, black and blue), a multiple-choice experiment was performed in the laboratory using the zebrafish (Danio rerio) as test species. The results indicated that the zebrafish preferred to ingest blue fragments, while avoiding green and white fragments when faced with an equitable supply of different-colored MPs. Although it is not yet clear how the color of the plastic is related to selectivity and consumption in freshwater fish, the visual skills of the fish could help to explain why certain colors are attractive to a particular fish species. |
