Information on size frequency distribution,the width-weight relation and growth parameters of the crabs Callinectes arcuatus and C. bellicosus is presented.The data comes from samples taken with a trawl net both day and night on a monthly basis from March 1998 toFebruary 2000 in a coastal lagoon from Gulf of California. C. bellicosus (n= 878) was more abundant than C.arcuatus (n= 357) and its size frequency distribution presented carapace width CW ranges of 8.4-166 mm and9-130 mm respectively. Both populations were mainly represented by juveniles (75 mm in CW) ranging from37 to 75 mm in CW, and adults (>75 mm in CW) between 76 and 90 mm in CW. In both species the widthweightrelation showed that males grow more than females, with an isometric growth tendency being observed.The growth parameters for C. arcuatus estimated using the von Bertalanffy Model, were: K= 0.84 year-1, L∞=140 mm to = -0.12 for C. arcuatus, and K= 0.9 year -1, L∞= 169 mm to = -0.11 for C. bellicosus. These resultsshowed that the relative age at which maximum growth is attained is between three and four years for both species.Rev. Biol. Trop. 55 (1): 225-233.
