Cette Ã©tude a concernÃ© les pÃªcheries des localitÃ© de Sidi-Kompenga et de Sirba situÃ©es Ã lâ€™Est du Burkina Faso et a eu pour objectif de faire lâ€™Ã©tat des lieux de la faune ichtyologique. Lâ€™Ã©chantillonnage sâ€™est dÃ©roulÃ© durant les pÃ©riodes de crue et dâ€™Ã©tiage. Des pÃªches expÃ©rimentales combinant plusieurs engins de pÃªche ont Ã©tÃ© menÃ©es sur six stations. Quatre paramÃ¨tres physico-chimiques ont Ã©tÃ© mesurÃ©s : la tempÃ©rature, le pH, la conductivitÃ© et la transparence. La richesse taxinomique ainsi que les indices de diversitÃ© de Shannon, dâ€™Ã©quitabilitÃ© de Pielou et de Simpson ont Ã©tÃ© dÃ©terminÃ©s. Les tempÃ©ratures moyennes Ã©taient comprises entre 27,8 et 31,2 Â°C et entre 28,6 et 30,9 Â°C respectivement au niveau de Sidi-Kompenga et de la Sirba. Quant aux pH moyens, ils Ã©taient compris entre 7,3 et 8,3 et entre 7,04 et 8,24 respectivement au niveau de SidiKompenga et de la Sirba. Quant Ã la faune ichtyologique, on a dÃ©nombrÃ© 29 espÃ¨ces regroupÃ©es en 22 genres et 11 familles au niveau de Sidi-kompenga et 28 espÃ¨ces regroupÃ©es en 23 genres et 11 familes au niveau de Sirba. Les indices de Shannon Hâ€™, dâ€™Ã©quitabilitÃ© de Pielou et de Simpson calculÃ©s ont Ã©tÃ© respectivement 2,67 ; 0,79 et 0,90 Ã Sidikompenga et 2,66 ; 0,80 et 0,91 Ã Sirba. Les familles des Alestidea et des Mormyridea ont Ã©tÃ© les plus diversifiÃ©es avec chacune 6 espÃ¨ces dont Sarotherodon galilaeus, Oreochromis niloticus et Coptodon zillii ont Ã©tÃ© les 3 espÃ¨ces les plus courantes dans les captures. Les rÃ©sultats montrent que les deux pÃªcheries prÃ©sentent une population piscicole diversitÃ©.
This study concerned the fisheries of the localities of Sidi-Kompenga and Sirba located in the East of Burkina Faso and had the objective of taking stock of the fish fauna. The sampling was carried out during the periods of high and low water levels. Experimental fishing combining several fishing gears was carried out at six stations. Four physico-chemical parameters were measured: temperature, pH, conductivity and transparency. The taxonomic richness as well as the Shannon diversity, Pielou equitability and Simpson indices were determined. Mean temperatures were between 27.8 and 31.2 Â°C and between 28.6 and 30.9 Â°C respectively at Sidi-Kompenga and Sirba. Average pH values were between 7.3 and 8.3 and 7.04 and 8.24 respectively at Sidi-Kompenga and Sirba. As for the fish fauna, there were 29 species grouped in 22 genera and 11 families at the level of Sidi-kompenga and 28 species grouped in 23 genera and 11 families at the level of Sirba. The Shannon H', Pielou and Simpson equitability indices calculated were respectively 2.67; 0.79 and 0.90 at Sidi-kompenga and 2.66; 0.80 and 0.91 at Sirba. The families Alestidea and Mormyridea were the most diverse with 6 species each, of which Sarotherodon galilaeus, Oreochromis niloticus and Coptodon zillii were the 3 most common species in the catches. The results show that both fisheries have a diverse fish population.
