Alternative Title
Reproduction of the sand smelt Atherina boyeri Risso, 1810 in marine and lagoonal environments.
Abstract
The authors have studied the sexuality and the reproduction of two sand smelt populations. The first originates from the marine area of Monastir, the second from Ichkeul Lake. The sex-ratio variations in relation to time and fish size have been analyzed. The size of first sexual maturity has been determined and the process of the sexual cycle has been described. Some divergences have been noticed between marine and lagoonal sand smelts.
Les auteurs ont étudié la sexualité et la reproduction de deux populations d'athérines, l'une provenant du secteur marin de Monastir et l'autre du lac Ichkeul. Les variations du sex-ratio dans le temps et en fonction de la taille des poissons ont été analysées. La taille de première maturité sexuelle a été déterminée et le déroulement du cycle sexuel a été décrit. Des divergences ont été mises en évidence entre les athérines marines et lagunaires.
