Age determination of the grey mullet Mugil cephafus L. and the white mullet Mugif curema V. (Pisces: Mugilidae) in Tamiahua Lagoon, Veracruz

Age determination of the grey mullet Mugil cephafus L. and the white mullet Mugif curema V. (Pisces: Mugilidae) in Tamiahua Lagoon, Veracruz

In this study, by means of the sagittu otolith analysis, five and six age groups and the relation age-length of Mugil cephalus and M. curemu, respectively, in Tamiahua Lagoon, Veracruz (Mexico), are established. The anatomy of the scales and sugitta of both species is described. The fast growing ban...

The anatomy of the scales and sugitta of both species is described. The fast growing bands on the edges show that their formation was higher from March to August for M. cephulus, and from July to November for M. curemu. The development of those bands was related to the spawning migration in both species. The constants of the growth equation of von Bertalanffy were calculated for the species and their sexes, using the scales and the otoliths. Differences in growth between sexes were detected; generally, the females reach a bigger size than the males at the same age in both mulle species. The scales and the otoliths may be used indistinctly in the age determination of both sexes of the species; nevertheless, the otolith showed a better tit to the growth equation. En el presente estudio se establecen cinco y seis grupos de edad así como la relación edad-longitud, mediante el análisis del otolito sugitta de Mugil cephalus y M. curema, respectivamente, para la laguna de Tamiahua, Veracruz (México). Se describe la anatomía de escamas y otolitos para ambas especies. Las bandas de crecimiento rápido en los bordes indicaron que éste fue mayor en los meses de marzo a agosto y de julio a noviembre para M. cephalus y M. curemu, respectivamente. El desarrollo de dichas bandas se relacionó con la emigración de desove de ambas especies. Fueron calculadas las constantes del crecimiento de la ecuación de von Bertalanffy para ambas especies y sus sexos, utilizando la edad estimada por medio de escamas y otolitos. Se encontraron diferencias de crecimiento entre sexos, siendo éste mayor en las hembras que en los machos de ambas especies. Se concluye que tanto las escamas como los otolitos se pueden usar indistintamente en la determinación de la edad de los sexos de ambas especies; sin embargo, el mejor ajuste al modelo del crecimiento se obtiene utilizando la lectura de los otolitos.
