%X Length-weight relationships and condition factors are among the commonly used parameters to link the length of a fish to its weight. The present study was initiated to find out the growth patterns and overweight status of 15 fish species in the Lo¨¦m¨¦ basin in Mayombe, Republic of Congo. In the period from February 2020 to September 2021, sampling was carried out in eight stations, following a standardised capture method using four gillnets of 10, 12, 15, and 25 mm mesh size and a hawk net of 1.90 m radius with 10 mm mesh size. Length-weight relationships were calculated according to P = aLS<em><sup>b</sup></em> and the condition factor, using K = (P/LS<sup><em>b</em></sup>)* 100. A total of 1153 specimens representing 15 species, 10 genera and 6 families were recorded. The number of specimens ranged from 10 to 214 for <em>Chrysichthys auratus</em> and <em>Enteromius camptacanthus</em>, respectively. The allometry coefficient b minimum of 2.697 for <em>Chromidotilapiamelaniae</em> and maximum of 3.589 for <em>Garraornata</em>, with a mean of 3.03 ¡À 0.2 is significantly not different from 3 at the 0.05 probability threshold and indicates isometric growth for almost all species, except for <em>E. camptacanthus</em> where <em>b</em> = 2.858 was statistically different from 3 at the same threshold. The positive and high values of the coefficients of determination <em>r</em><sup>2</sup> = 0.787-0.989 of the species, obtained during this study, suggest that weight increases with size in the fish of the Lo¨¦m¨¦ basin. The average condition factor varies from 0.524 ¡À 0.064 for <em>G. ornata</em> to 4.917 ¡À 0.440 for <em>C. melaniae</em>.
