The reproduction of Liza falcipinnis were investigated in both lagoons (Ebrié and Grand-Lahou) from January 2006 to december 2007. 2162 specimens were examined (914 and 1248 respectively in Ebrié andExpand

Reproduction and development in some species of the weakly electric genus Campylomormyrus (Mormyridae, Teleostei)
Injection of an artificial GnRH hormone allowed us to obtain ripe eggs and sperm and to perform successful artificial reproduction of four species of the mormyrid genus Campylomormyrus and C. compressirostris, which produce yolky, slightly sticky eggs. Expand
Interaction of the mormyrid fish Mormyrus kannume (Forsskål, 1775) reproduction and feeding intensity with the environment in a Nile Delta Canal,Egypt
The susceptibility of this fish species to change in those variables indicates its vulnerability to any adverse climatic change and the relationship between each of fecundity, egg diameter and gonadosomatic index and the female length or age were examined, and the mathematical correlations were presented.

Spatial and seasonal fish community patterns in impacted and protected semi-arid rivers of Burkina Faso
a b s t r a c t This research evaluates fish assemblages in both impacted and protected areas in tropical seasonal small rivers in Burkina Faso. The study zones were, respectively, in theExpand
Reproductive strategy of Labeo senegalensis Valenciennes 1842 (Teleostei: Cyprinidae) in the Ouémé basin, Benin
Oocyte diameter frequency distribution suggests synchronous development with a single total spawning in Labeo senegalensis, a highly fecund fish that presents a seasonal cycle of reproduction from May to October during the rainy season. Expand
Stratégies de reproduction du poisson-chat Synodontis schall (Bloch Schneider, 1801) (Siluriformes, Mochokidae) en milieux lacustre et fluviatile (bassins Bia et Agnébi, Côte d\'Ivoire)
La reproduction du poisson-chat Synodontis schall a ete etudiee en milieux lacustre et fluviatile, respectivement dans les rivieres Bia et Agnebi. Le caractere permanent de l\'eau, dans le lac aExpand
Control of Gonadal Maturation and Regression by Experimental Variation of Environmental Factors in the Mormyrid Fish, Mormyrus rume proboscirostris
Investigation of spawning, external appearance of the females and in part histology of gonads of the African mormyrid fish Mormyrus rume proboscirostris found that conductivity changes are sufficient to induce gonadal maturation and regression, respectively. Expand
Freshwater ecology and biodiversity in the tropics: what did we learn from 30 years of onchocerciasis control and the associated biomonitoring of West African rivers?
To release humans from river blindness, the Onchocerciasis Control Programme in West Africa (OCP) was implemented in 1974 and ended in 2002. It has emphasized preservation of biodiversity andExpand
Freshwater ecology and biodiversity in the tropics: what did we learn from 30 years of onchocerciasis control and the associated biomonitoring of West African rivers?
After almost 30 years of monitoring the effects of larviciding in West African rivers it can be concluded that the effect of insecticides on the aquatic fauna was usually low for fish, whereas results for invertebrates indicate changes of taxa composition and community structure even at the family level, which should not have affected the general functioning of the aquatic system.
