“…Riverine fish are bound to shallow shoreline zones that serve as important nursery habitats Keckeis et al, 1997). These sensitive areas are most affected by ship induced wake and splash, which lead to a drastic dislocation of YOY microhabitats (Zauner and Schiemer, 1994;Mazumder et al, 1996;Ali et al, 1999;Arlinghaus et al, 2002;Wolter and Arlinghaus, 2003).…”

Navigation alters the ecology of large inland waterways via engineering and more directly by emission of hazardous substances and wave wash. We investigated the potential effects of the latter on the early life history stages of riverine fish, which have their nursery zones generally located in shallow areas with low current and higher water temperatures. Ship induced wave wash causes the following impacts on fish during their early life history stages: i) short-term dislocation of suitable larval and juvenile fish habitats due to wake and splash; ii) water velocities during ship passages frequently exceed maximum swimming performances of 0+fish; and iii) suspended solids concentrations in the inshore habitats increase dramatically and limit the foraging efficiency of young of the year fish (YOY). In situ conditions during ship passages were investigated in three different inshore zones of the Austrian Danube with respect to wake and splash patterns, changes in water velocity and turbidity. These navigation induced conditions in the main nursery zones of riverine fish were set in comparison to results on swimming performances and capacities of larval and juvenile fish obtained in experimental studies. Engineering in large river systems in Europe and USA has resulted in a strong reduction of natural shoreline structures. Within this altered situation, navigation induced wave wash has a strong and cumulative effect on riverine fish recruitment and, hence, contributes to the general ongoing decline of native fish stocks in inland waterways. These aspects require particular consideration in river restoration programs to mitigate the effects of navigation, especially with respect to the intended expansion of European water ways within EC projects like TEN-T and NAIADES.

“…In the confined channels of rivers, large vessels can generate uniquely large physical disturbances, including sediment resuspension (Adams and Delisio 1990); altered water-velocity distributions, including flow reversals; transient changes in water-surface elevation (Bhowmik and Mazumder 1990); and changes in Reynolds stress distributions, particularly within the nearshore littoral areas (Mazumder et al 1993).…”

We provide the first evidence for chronic effects of disturbance by commercial vessels on the spatial distribution and abundance of fishes in the channels of a large river. Most of the world's large rivers are intensively managed to satisfy increasing demands for commercial shipping, but little research has been conducted to identify and alleviate any adverse consequences of commercial navigation. We used a combination of a gradient sampling design incorporating quasicontrol areas with Akaike's information criterion (AIC)-weighted model averaging to estimate effects of disturbances by commercial vessels on fishes in the upper Mississippi River. Species density, which mainly measured species evenness, decreased with increasing disturbance frequency. The most abundant species -gizzard shad (Dorosoma cepedianum) and freshwater drum (Aplodinotus grunniens) -and the less abundant shovelnose sturgeon (Scaphirhynchus platorhynchus) and flathead catfish (Pylodictis olivaris) were seemingly unaffected by traffic disturbance. In contrast, the relative abundance of the toothed herrings (Hiodon spp.), redhorses (Moxostoma spp.), buffaloes (Ictiobus spp.), channel catfish (Ictalurus punctatus), sauger (Sander canadensis), and white bass (Morone chrysops) decreased with increasing traffic in the navigation channel. We hypothesized that the combination of alteration of hydraulic features within navigation channels and rehabilitation of secondary channels might benefit channel-dependent species.Résumé : Nous présentons les premières données qui montrent que les navires commerciaux causent des perturbations chroniques de la répartition spatiale et de l'abondance des poissons dans les chenaux d'une grande rivière. La plupart des grandes rivières du globe sont aménagées de façon intensive pour accommoder les besoins grandissants du transport fluvial commercial, mais il y a peu de recherches sur l'identification et la mitigation des conséquences négatives possibles de la navigation commerciale. Afin d'évaluer les effets des perturbations causées par les navires commerciaux sur les poissons du Mississippi supérieur, nous utilisons en combinaison un plan d'échantillonnage des gradients avec des quasi-zones témoins et la pondération moyenne des modèles à l'aide du critère d'information d'Akaike (AIC). La densité des espèces, qui représente surtout l'équitabilité des espèces, diminue en fonction de la fréquence des perturbations. Les espèces les plus abondantes -l'alose à gésier (Dorosoma cepedianum) et le malachigan (Aplodinotus grunniens) -et certaines espèces moins abondantes comme l'esturgeon à museau plat (Scaphirhynchus platorhynchus) et la barbue à tête plate (Pylodictis olivaris) ne sont apparemment par affectées par les perturbations causées par le transport. En revanche, les abondances relatives des laquaiches (Hiodon spp.), des suceurs (Moxostoma spp.), des buffalos (Ictiobus spp.), des barbues de rivière (Ictalurus punctatus), des dorés noirs (Sander canadensis) et des bars blancs (Morone chrysops) diminuent en fonction de l...

“…Thus, it was hypothesized that YOY fish densities should be substantially higher in bays (convex banks) than in the straight reaches of the canal where shipping influence should be substantially higher (Zauner & Schiemer, 1992). Recognizing that shipping produces a harsh environment in the littoral because of wave breakage and propagation of wakes (Mazumder et al, 1996), the study included measurements and analysis of velocity patterns that evolved in the straight reaches and U-turn bays as ships passed along the canal.…”

The young-of-the-year (YOY) fish community in Oder-Havel-Kanal, a navigable canal in the German lowlands, assessed from May to October 1999, was dominated by tolerant species especially roach Rutilus rutilus and perch Perca fluviatilis. Roach dominance was high in May and June and low during the rest of the sampling period. The dominance pattern of perch was inversely related to that of roach. Significantly higher densities of significantly smaller YOY fishes were found in bays compared with the straight reaches of the main channel which was the result of an aggregation of 0+ year roach in bays in May and June. Parallel to low structural variability (spawning and nursery habitats), the intensive ship traffic may have been a major force structuring the fish communities in the canals. Measured ship-induced flow velocity in straight reaches was about four times higher than in bays of the canal. Maximum flow velocities caused by barge tows were also four times higher than those induced by pleasure boats. The study demonstrated the relatively low fish reproductive potential of a navigable, artificially embanked lowland canal. To improve fish reproduction, modification of canal banks is highly advisable to preserve existing bays and tributaries and even to create additional ones.
