Dans le bassin du Niger, le debut de la gametogenese de Brycinus leuciscus parait synchrone de la remontee du Front inter-tropical a l'origine des variations saisonnieres du milieu, mais la croissance ovarienne ne se poursuit qu'en presence des conditions de debut de crue. La comparaison du cycle de reproduction de B. leuciscus, sous des conditions naturelles differentes (crue decalee), met en evidence une relation entre l'evolution du rapport gonado-somatique des femelles et les variations de… Expand
Modifications de la croissance de Brycinus leuciscus ( Characidae ) suite aux changements hydroclimatiques et halieutiques dans la plaine inondée du delta central du Niger
TLDR
La faible première croissance des 1+ traduit cette forte ponction halieutique à partir d'une taille de recrutement des engins de pêche estiméeà 55 mm. Expand

Control of Gonadal Maturation and Regression by Experimental Variation of Environmental Factors in the Mormyrid Fish, Mormyrus rume proboscirostris
TLDR
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

Influence de quelques facteurs de l'environnement sur la fonction de reproduction chez les poissons
TLDR
The various environmental factors, interacting with endogenous parameters, depend on the physiology and health of the animal at a given time of the year or the day and on the degree of domestication. Expand
The significance of photoperiodicity, water temperature and an inherent endogenous rhythm for the production of viable eggs by the African catfish, Clarias gariepinus, kept in subtropical ponds in Israel and under Israeli and Dutch hatchery conditions
TLDR
It is concluded that for propagation of C. gariepinus throughout the year, independent of the seasons, broodfish should be reared and kept in hatchery tanks at a water temperature of 25°C, with proper feeding, in the presence of males, and at any local light periodicity. Expand
Oogenesis in five species of grey mullets (Teleostei, Mugilidae) from natural and landlocked habitats.
TLDR
The seasonal histological changes in the ovaries of specimens of five species of Mugil caught in natural habitat were compared with those of specimens in fish ponds and Lake Tiberias to study the Gonado-Somatic Index (GSI) of the various species of mullets. Expand

Abstract A characteristic electric organ discharge display in social encounters between mormyrid fish is a temporary discharge cessation. Using this response, we have investigated the useful range ofExpand
