Table 4. Effects of developmental stage and season on CL, W, and the W/CL index.
Results of separate General Lineal Models testing for the effects of developmental stage (two levels, pueruli and first juveniles) and season (12 levels, from autumn 2010 to summer 2013) on three response variables: carapace length (CL, mm), weight (W, mg), and W/CL index (condition factor) obtained from individuals collected at Puerto Morelos from autumn 2010 to summer 2013.
