Ruiz-Velazco Biología sex growth lobster octopus tilapia Growth parameters are an important component for the stock assessment of exploited aquatic species.However, it is often difficult to apply direct methods to estimate growth and to analyse the differences betweenmales and females, particularly in tropical areas. The objective of this study was to analyse the inter-cohortgrowth of three tropical resources and discuss the possible fisheries management implications. A simple methodwas used to compare individual growth curves obtained from length frequency distribution analysis, illustratedby case studies of three tropical species from different aquatic environments: tilapia (Oreochromis aureus), redoctopus (Octopus maya) and the Caribbean spiny lobster (Panulirus argus). The analysis undertaken comparedthe size distribution of males and females of a given cohort through modal progression analysis. The techniqueused proved to be useful for highlighting the differences in growth between females and males of a specificcohort. The potential effect of extrinsic and intrinsic factors on the organism’s development as reflected in thesize distribution of the cohorts is discussed. Rev. Biol. Trop. 63 (3): 617-627.
