An analysis was made of internal and ambient temperatures, depth, and time of day registered in 68 archival tags recovered from tuna caught mostly in sets associated with dolphins by Mexican purse-seine vessels. Tuna were classified into 3 age groups (I, II, and III) for analyses. Vertical movements were analyzed by dividing the water column into 10 depth strata. The 3 age groups remained the longest in the uppermost stratum (0-25 m), and their presence began to diminish in subsequent strata, with some occasional visits at &gt;500-m depths. In the &gt;500 m stratum, age group III was the one with the longest time investment with 45 min on average. Presence at different depths throughout the day showed significant differences among age groups (Wald&#8217;s test expressed as &#967;2, P &lt; 0.05). The physiological adaptation of yellowfin tuna to maintain minimal changes in its internal temperature at different depths gives it the advantage to expand its food search to deep zones where temperature oscillates around 5 ºC.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Se describe el uso del hábitat vertical del atún aleta amarilla, Thunnus albacares, capturado y liberado con marca archivadora en la Reserva de la Biosfera Archipiélago de Revillagigedo, México, durante el periodo 2006-2011. Se analizó la serie de datos de temperatura interna, temperatura del ambiente, profundidad y hora del día almacenados en 68 marcas archivadoras recuperadas de los atunes capturados, en su mayoría, en lances pesqueros asociados a delfines por barcos cerqueros atuneros de bandera Mexicana. Los atunes fueron clasificados para su análisis en 3 grupos de edad (I, II y III). Los movimientos verticales se analizaron dividiendo la columna de agua en 10 estratos de profundidad. Los 3 grupos de edad invirtieron más tiempo en el estrato superficial (0-25 m) y su presencia fue disminuyendo a medida que fue aumentando la profundidad, con visitas ocasionales a profundidades mayores que 500 m. En el estrato de &gt;500 m, el grupo de edad III, fue el que más tiempo invirtió con un promedio de 45 min. La presencia a diferentes profundidades a lo largo del día mostró diferencias significativas entre los grupos de edad (prueba &#967;2 de Wald, P &lt; 0.05). La adaptación fisiológica del AAA para mantener cambios mínimos en su temperatura interna a diferentes profundidades es una ventaja para ampliar la búsqueda de alimento en zonas profundas donde la temperatura del ambiente osciló alrededor de los 5 ºC.]]></p></abstract>
