- Otolith shape analysis as a tool for population discrimination of the white grunt (Haemulon plumieri) stock in the northern coast of the Yucatan Peninsula, Mexico Christina Treinen-Crespo Harold Villegas-Hernández Sergio Guillén-Hernández Miguel Ángel Ruiz-Zárate Carlos González-Salas Biología stock otolith shape discrimination Haemulon plumieri In this study, the population structure of the white grunt (Haemulon plumieri) from the northern coast of the Yucatan Peninsula was determined through an otolith shape analysis based on the samples collected in three locations: Celestún (N 20°49’,W 90°25’), Dzilam (N 21°23’, W 88°54’) and Cancún (N 21°21’,W 86°52’). The otolith outline was based on the elliptic Fourier descriptors, which indicated that the H. plumieri population in the northern coast of the Yucatan Peninsula is composed of three geographically delimited units (Celestún, Dzilam, and Cancún). Significant differences were observed in mean otolith shapes among all samples (PERMANOVA; F2, 99 = 11.20, P = 0.0002), and the subsequent pairwise comparisons showed that all samples were significantly differently from each other. Samples do not belong to a unique white grunt population, and results suggest that they might represent a structured population along the northern coast of the Yucatan Peninsula. 2012 artículo científico 1659-455X https://www.redalyc.org/articulo.oa?id=633766719011 en http://www.redalyc.org/revista.oa?id=6337 Revista Ciencias Marinas y Costeras application/pdf Universidad Nacional de Costa Rica Revista Ciencias Marinas y Costeras (Costa Rica) Vol.4
