Baras, E., H. Lambert and J. C. Philippart (1994). A comprehensive assessment of the failure of Barbus barbus spawning migrations through a fish pass in the canalized River Meuse (Belgium). Aquatic Living Resources. 7:181-189.
This paper presents a comprehensive study of the impact of damming on the spawning migrations of Barbus barbus in the canalized River Meuse (Belgium). A Denil fish pass on the Ampsin-Neuville dam was controlled 251 times in 1989- 1993. The most striking feature is the almost complete absence of barbel. Most captures of barbel in the fish pass in 1989 were clumped and related with spawning migrations. The variables involved in the attractivity condition set refer indirectly to the influence of water catchment by a hydroelectric plant and to the relative importance of the flow in the pass. The study concludes that this additional condition set significantly interfere with the natural environmental stimuli triggering spawning migrations in barbel and questions the effectiveness of the thermally related reproductive strategy of the species.
