From the results obtained in four years of monthly fish sampling and salinity and temperature verification of Lagoa Rodrigo de Freitas lagoon, an analysis of the monthly capture distribution of the nine most representative species, Brevoortia áurea (Spix, 1829), B. pectinata (Jenyns, 1842), Genidens genidens (Valenciennes, 1839), Geophagus brasiliensis (Quoy & Gaimard, 1824), Cerres aprion Cuvier, 1829, Jenynsia lineaía (Jenyns, 1842), Mugil liza (Valenciennes, 1836), Poecilia vivipara (Bloch & Schneider, 1801) and Xenomelani-ris brasiliensis (Quoy & Gaimard, 1824) was performed. The results show that Lagoa waters have an average salinity of 11.06% during the sampling period. Temperature showed its highest values from November to February and lowest values from June to August. G. brasiliensis, G. aprion, J. lineata,M. liza,P. viviparaeX. brasiliensis were constant during the 4 years. B. áurea showed highest frequency in year IV. B. pectinata was constant in years I and II and G. genidens showed only sparse captures.
