Observations concerned three stations representative of the artificially modified main channel : dyked lotic channel, storage reservoir and diversion canal. Twenty-nine species among the thirty-three known from this part of the river have been captured in the three stations during Spring. Five euryoecious species (Rutilus rutilus, Alburnus alburnus, Leuciscus cephalus, Anguilla anguilla and Lepomis gibbosus) with strong occurences in samples (more than sixty percent) represent ninety-two percent of catches. During the last decade, three new species appeared in the Lower Rhône fish community : Silurus glanis (1987), Pseudorasbora parva (1989) and Carassius auratus (1990). Apart from anthropogenic disturbances, interannual variability in species richness and fish abundances are principally determined by: successive and significant hydroclimatic events (hydrological deficit from 1989 to 1993) and high floods (october 1993 and january 1994), ecological strategies of species facing abiotic and biotic constraints. The results prove the interest of long-term studies to appreciate actual variability in large river fish assemblages.
