Abstract:
Morphology, morphometry and growth rings of the otoliths: sagitta, asteriscus and lapillus of Mugil cephalus from Central Mexican Pacific were analyzed. The three pairs of otoliths (sagitta, asteriscus and lapillus), right and left and sex differences were studied. The samples were obtained from the commercial catch in the months of August to December 2007, January to March 2008 and July 2011. In all cases it was observed that growth in otoliths is eccentric with respect to the core. The distance from the core to each age growth ring was measured. Relations between total length of the fish and length and width of the otolith showed that these structures can be used to determine the age in fish. Ten growth rings were identified in sagittae and asterisci. Due to its thickness, these marks could not be seen in lapilli. During the first stages of development, female sagittae and lapilli have larger size but once they reach sexual maturity, males’ otoliths reach larger sizes.
