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... |

The aim of the present study was to ascertain the size at sexual maturity in females of the crab Sesarma rectum Randall, 1840 by comparing gonadal maturity to morphologic maturity (using abdomen-width data). The relative growth of the abdomen was analysed for all growth phases (for each 3-mm carapace width size class), and the slopes of the separate allometric relationships were compared through analysis of covariance (ANCOVA) from log e-transformed data to detect changes in the level of allometry during ontogeny. The physiological size at maturity (gonadal criteria) was determined through a logistic curve, indicating the size at which 50% of females presented mature gonads (M50 = 17.4 mm CW). The highest allometric levels occurred in growth phases 2 and 3... |
