- Otoliths analysis of Mugil curema (Pisces: Mugilidae) in Cuyutlan Lagoon, Mexico E. Espino-Barr M. Gallardo-Cabello E.G. Cabral-Solís M. Puente-Gómez A. García-Boa Agrociencias Sagitta lapillus asteriscus white mullet Morphology, morphometry and growth rings of the otoliths: sagitta, asteriscus and lapillus of Mugil curema of Cuyutlan Lagoon, Colima, Mexico were analyzed, also the difference between right and left and sexes were studied. Samples were obtained from the commercial catch in the months of August to October 2007, August 2008 and July 2011. In all cases it was observed that the growth in otoliths is eccentric with respect to the core. Relations between total length of the fish and length and width of the otolith showed that this structure is useful in the growth description of fish. Six growth rings were identified in saggitae and asterisci: specimens with two rings measured 21.80 cm of total length (TL) (± 1.41 standard deviation), with three rings 22.90 (± 0.91), with four rings 25.30 (± 0.39), with five rings 28.30 (± 0.78), and with six rings 31.10 (± 2.22). Due to its thickness, these marks could not be seen in lapilli. During the immature stage of development, female otoliths have larger size, but once they reach sexual maturity, males’ otoliths reach larger lengths. 2013 artículo científico 0188-7890 https://www.redalyc.org/articulo.oa?id=83725698003 https://www.redalyc.org/journal/837/83725698003/ https://www.redalyc.org/journal/837/83725698003/html/ https://www.redalyc.org/journal/837/83725698003/83725698003.epub https://www.redalyc.org/journal/837/83725698003/movil en http://www.redalyc.org/revista.oa?id=837 Avances en Investigación Agropecuaria application/pdf Universidad de Colima Avances en Investigación Agropecuaria (México) Num.1 Vol.17
