Comparison of the Allometry Coefficient of the Length-Weight and Length-Length Relationship between Selene brownii, S. vomer and S. setapinnis Caught in the Gulf of Mexico
This work presents a comparison of the length-weight and length-length allometric relationships between six measurements: length pattern (LP), cephalic length (CL), maximum depth (MA), caudal peduncle depth (CPD) ocular diameter (OD) and weight (W) of three species of the genus Selene (S. brownii, S...

| Sumario: | This work presents a comparison of the length-weight and length-length allometric relationships between six measurements: length pattern (LP), cephalic length (CL), maximum depth (MA), caudal peduncle depth (CPD) ocular diameter (OD) and weight (W) of three species of the genus Selene (S. brownii, S. vomer and S. setapinnis) caught in the port of Veracruz, Mexico, using a beach seine of 800 m. The results show certain relationships between all measurements of S. brownii (an isometric relationship and four negative allometric relationships); S. vomer showed only four relationships (two isometric and two negative allometric); and S. setapinnis showed three relationships (all negative allometric); the results of S. vomer and S. setapinnis are consistent with those reported by Muto et al. (2010). The comparison of the coefficients of allometry between the three species allowed us to determine that S. brownii and S. vomer differed significantly in two of the four allometric coefficients of length-weight relationships common to them, and in three of the four allometric coefficients of length-length relationships common to them. S. brownii and S. setapinnis differed significantly in two of the three allometric coefficients of length-weight relationships common to them and in the only allometric coefficient of length-length relationships common to them. Finally, S. vomer and S. setapinnis differed significantly in the three common allometric coefficients of length-weight relationships, and in the only common allometric coefficient of length-length relationship. |
