- W2108690695 abstract "Reproduction of an estuarine tilapia (Sarotherodon melanotheron Rüppell, 1852) landlocked in a West-African man-made Lake. Reproduction parameters of a landlocked population of black-chinned tilapia Sarotherodon melanotheron have been studied for 2 years and compared to literature data obtained from their natural environment. Sex-ratio (year 1: 1:2.69; year 2: 1:1.96) is in favour of females and shows seasonal variations. Males mature earlier (year 1: 129 mm SL; year 2: 126 mm SL) than females (year 1: 135 mm; year 2: 136 mm SL). Gonad maturation cycle is continuous. All these results are generally similar to those obtained in the natural environment. However, a lower fecundity is noted in Lake Ayame. Accordingly, an increase in oocyte diameter is observed. The average condition factor in the lake ranges between values observed in lagoon populations and therefore indicates a good adaptation of this species to fresh water conditions. Des paramètres de la reproduction d'une population isolée du tilapia Sarotherodon melanotheron ont été étudiés durant 2 années consécutives et comparés avec les données de la littérature obtenues sur des populations vivant dans son milieu naturel. Le sexe-ratio (année 1 : 1:2,69 ; année 2 : 1:1,96) en faveur des femelles varie de façon saisonnière. Les mâles atteignent la maturité sexuelle plus rapidement (année 1 : 129 mm LS ; année 2 : 126 mm LS) que les femelles (année 1 : 135 mm ; année 2 : 136 mm LS). Le cycle de maturation des gonades est continu. Ces résultats sont dans l'ensemble semblables à ceux obtenus dans le milieu naturel de l'espèce. Cependant, une fécondité inférieure et un diamètre ovocytaire plus grand sont notés dans le lac d'Ayamé. Le facteur de condition moyen des populations du lac, intermédiaire entre des valeurs observées dans les milieux lagunaires, indique une bonne adaptation de l'espèce aux conditions d'eau douce du lac." @default.
