MÉTODOS: Se determinaron las edades de 43 delfines (algunos nacidos en cautiverio), se obtuvieron las longitudes totales de todos los individuos y las longitudes craneales de 12 toninas, así como el sexo de cada uno (17 machos y 26 hembras). Se verificó si existían diferencias estadísticas significativas entre los sexos y entre las localidades. De los 43 animales, 13 son crías de entre 10 meses de edad y cinco años.  RESULTADOS: Para los machos y las hembras maduros sexualmente de la localidad de Quintana Roo, los promedios e intervalos de la longitud total y la edad de los individuos fueron los siguientes: los tres machos, de 18 años; longitud total promedio = 253.33 cm ± 14 cm (intervalo 239-267 cm, n = 3). Las hembras, todas mayores de 10 años; longitud total promedio = 250.6 cm ± 7.5 cm (intervalo 239-261 cm, n = 8). En la localidad de Tabasco, los valores fueron: todos los machos, mayores de nueve años; longitud total promedio = 236.13 cm ± 5.2 cm (intervalo 238-240 cm, n = 4). Todas las hembras, mayores de los ocho años; longitud total promedio = 239.4 cm ± 7.4 cm (intervalo 227-246 cm, n = 5). El total de toninas cubanas fue de siete; por tanto, los valores se consideraron aparte, con objeto de ser comparados con las toninas de la misma edad y sexo de las otras dos localidades.  DISCUSIÓN: Los valores de Lmax de las toninas del sur del Golfo de México son parecidos a los de las toninas de Texas y Florida. No se encontraron diferencias estadísticas significativas. Tampoco se hallaron diferencias en el crecimiento de las Lmax entre delfines adultos ni entre localidades ni entre los sexos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  INTRODUCTION: In order to know the growing rate of the captive bottlenose dolphins (Tursiops truncatus) of Via Delphi, the total length and age from three different geographic zone dolphins, from Quintana Roo and Tabasco in Mexico, and some individuals from Cuba (some dolphins were born in captivity) were recorded. The aim of this study was to establish if there were statistic differences between gender and among dolphins from different localities.  METHODS: The age of 43 dolphins was determined through the analysis of the growth layers groups (GLG´s), The gender of these dolphins was known, the total length of all of them, and the skull length of 12 toninas. The total sample was composed of 17 males and 26 females.  RESULTS: Of these 43 dolphins, 13 were calves between five years to 10 months old. Sexually mature dolphins from Quintana Roo, three males of 18 years old, presented a total length mean of = 253.33 cm ± 14 cm S. D. (range 239-267 cm, n = 3). Females older than 10 years old presented a total length mean of = 250.6 cm ± 7.5 cm S. D. (range 239-261 cm, n = 8). From de State of Tabasco, males older than nine years old, had a mean total length = 236.13 cm ± 5.2 cm S. D. (range 238-240 cm, n = 4). Females were older than eight years old, their mean total length = 239.4 cm ± 7.4 cm S. D. (range 227-246 cm, n = 5). About the Cuban dolphins, The sample from the Cuban dolphins was small (seven dolphins), they compared with dolphins of same sex and age of the two localities.  DISCUSSION: The values of Lmax of bottlenose dolphins in the Southern of the Gulf of Mexico are similar to the bottlenose dolphins in Texas and Florida, no significant statistical differences were found. Differences in growing rates were not found in the Lmax on adult dolphins between localities nor sexes.]]></p></abstract>
