Abstract: The length-weight relationship (LWR) and condition factor for18 fishes of three small lagoons of Ivory Coast were studied for fisheries management. Samples were monthly collected using traps, gillnets, harpoons and hawks between September 2015 and August 2016. Standard length of individuals was taken to the nearest 1 mm and body weight to the nearest 0.01 g. A total of 1886, 1825 and 1483specimens belonging to 18 species and 11 families were collected respectively in Ono, Kodjoboué and Hébé lagoons. All LWR were significant with a coefficient of determination (r²) varying from 0.731 (Chrysichthys nigrodigitatus) to 0.999 (Hepsetus odoe). The coefficient of allometry (b) ranged from 2.01 for Heterotis niloticus to 3.78 for Labeo courbie in Ono lagoon, from 2.03 for Chrysichthys nigrodigitatus to 3.03 for Clarias ebriensis in Kodjoboué lagoon and from 2.01 for Tilapia guineensis to 3.17 for Clarias ebriensis and Hemichromis fasciatus in Hébé lagoon. The K values varied from 0.79 ± 0.12to 2.89 ± 0.73 in Ono lagoon, from 0.70 ± 0.10 to 2.94 ± 0.30 in Kodjoboué lagoon and from 0.96 ± 0.27 to 2.86 ± 0.16 in Hébé lagoon. The value of both parameters indicates a good well-being of fishes in these lagoons.
