Los ba\u00f1os anest\u00e9sicos son usados en salmonicultura para manipular peces de forma segura durante selecci\u00f3n, transporte, tratamientos m\u00e9dicos y reproducci\u00f3n, reduciendo estr\u00e9s mediante sedaci\u00f3n. En Chile, los principales anest\u00e9sicos son MS-222 y benzoca\u00edna. Sin embargo, estudios recientes alertan sobre riesgos de esta \u00faltima: la investigaci\u00f3n de la Dra. Patricia Martins (Universidad de Aveiro, Portugal, 2025) en salmones del Atl\u00e1ntico criados en sistemas RAS evidenci\u00f3 que la benzoca\u00edna altera el microbioma cut\u00e1neo, provocando disbiosis y debilitando la barrera natural frente a pat\u00f3genos oportunistas. Se observ\u00f3 una reducci\u00f3n significativa en riqueza y diversidad bacteriana, predominando Gammaproteobacteria y Betaproteobacteria, lo que podr\u00eda aumentar la vulnerabilidad de los peces. Estos hallazgos subrayan la necesidad de reevaluar pr\u00e1cticas rutinarias y considerar impactos en microbiomas para mejorar la salud de los salmones y la sostenibilidad del cultivo.<\/p>\n
