Sagitta otolith of three demersal species in a tropical environment

The objective of this study was to describe the morphology and morphometry saggitta otoliths Polydactylus virginicus, Menticirrhus cuiaranensis Conodon nobilis in a tropical environment. Fishes were caught with rod reel competitive fishing events promoted 2014-2015 along coast Sergipe. A total 174 pairs sagitta P. 181 M. 77 C. extracted. In general, all three species analyzed here presented different shape indices. permutational multivariate analysis variance (PERMANOVA) demonstrated significant differences among ontogenetic phases within each using linear discriminant (LDA) 98.3% correct reclassification by species.
