This work was carried out with the aim of analyzing the growth parameters of Hepsetus odoe (Bloch, 1794) caught in the Ebrié lagoon with a view to contributing to the conservation and sustainable management of this fish. A total of 220 fish from commercial artisanal fishing were sampled from July 2022 to June 2023 in sector IV of the Ebrié lagoon. Each specimen was weighed and measured to the nearest gram and millimeter respectively. The length-weight relationship and the condition factor were calculated. The data collected were processed on Excel and Statistica 7.1 software. The size of the individuals varies from 11.2 to 36 cm and the weight oscillates between 10.2 and 196 g. The size frequency distribution is unimodal ([17; 20 [cm). In general, growth is of the positive allometry type regardless of sex and size. It appears that the species is gaining weight faster than it is growing. In males and females the mean value of the condition factor K is 0.638 ± 0.02 and 0.700 ± 0.014 respectively. These individuals are not overweight in their biotope regardless of their sex and size.

Abstract: (french)
Ce travail a été réalisé dans le but d’analyser les paramètres de croissance de Hepsetus odoe (Bloch, 1794) pêchée dans la lagune Ebrié en vue de contribuer à la conservation et à la gestion durable de ce poisson. Au total, 220 poissons issus de la pêche artisanale commerciale ont été échantillonnés de Juillet 2022 à juin 2023 au niveau du secteur IV de la lagune Ebrié. Chaque spécimen a été pesé et mesuré respectivement au gramme et au millimètre près. La relation longueur-poids et le facteur de condition ont été calculés. Les données récoltées ont été traitées sur Excel et le logiciel Statistica 7.1. La taille des individus varie de 11,2 à 36 cm et le poids oscille entre 10,2 et 196 g. La distribution des fréquences de taille est unimodale ([17; 20 [cm). En général, la croissance est de type allométrie positive quel que soit le sexe et la taille. Il apparaît que l’espèce grossit plus vite qu’elle ne grandit. Chez les mâles et les femelles la valeur moyenne du facteur de condition K est respectivement de 0,638 ± 0,02 et 0,700 ± 0,014. Ces individus ne sont pas en embonpoint dans leur biotope quel que soit leur sexe et leur taille.
