RESUMEN
El presente trabajo tuvo como objetivo describir y evaluar el método de marcado de lobos marinos 
comunes por decoloración del pelo, señalando ventajas y posibilidades de aplicación futuras. Para el marcado 
se utilizó un sello compuesto por letras y números desmontables donde se coloca el decolorante, conectado a 
una vara extensible que permite la correcta aplicación de la marca. Con esta metodología las marcas obtenidas 
tuvieron una duración máxima de 347 días perfectamente visibles, motivo por el cual y sumado al bajo costo y 
sencillez de aplicación, se sugiere que esta técnica es recomendable para estudios no invasivos en pinnípedos 
a corto y mediano plazo.


ABSTRACT. 
Hair bleaching marking technique in South American sea lionsOtaria  flavescens:Descriptionand  evaluation  of  method
The aim of this paper is to describe and evaluate the use of the hair discoloration 
method in South American sea lions, with an emphasis on its advantages and its potential use in future studies. 
For  marking,  stamp  removable  letters  and  numbers  were  used,  connected  to  an  extensible  rod.  The  bleached 
marks obtained had a maximum duration of 347 days perfectly visible and, because of the combination of low 
cost and application simplicity, this technique is considered suitable for both short and long term non-invasive 
studies in pinnipeds.
