【 摘 要 】

ABSTRACT: The evolution of a host-parasite system composed of Pomatoschistus microps-Kudoa camarguensis was investigated in the Vaccarès lagoon (Rhône river Delta, France) from 1993 to 1997. During this long-term monitoring, centennial flooding ofthe Rhône river occurred, leading to an inrush of about 110 million m³ of freshwater in the Vaccarès lagoon. The salinity drastically dropped from 14 to 5 g l^-1 in 1 wk. We observed that the annual prevalence and abundanceof the myxosporean parasite decreased from 12.18 in 1993 to 3.7% in 1997 and from 1.10 in 1993 to 0.27 in 1997, respectively. Here, we discuss the possible reasons for the rapid decline of this host-parasite system following the flood.
