“…Generally, in vertical slot fishways, the slot velocities are relatively unaffected by discharge (Rodríguez et al, 2006). Nevertheless, we observed changes in water velocity at the slots when flow increased in the fishway − it enlarged about 20% from low to high discharge − and also in the main recirculation areas at pools.…”

“…Vertical slot fishways were initially designed to accommodate large fluctuations in upstream and downstream water levels while maintaining constant such hydraulic factors as energy dissipation rate and velocity (Rajaratnam et al, 1986;Larinier, 2002b;Rodríguez et al, 2006;Wang et al, 2010). They have other advantages, though, notably that the slots offer passage opportunities throughout the water column, and are thought to be compatible with a broad range of species (Stuart and Berghuis, 2002;Mallen-Cooper and Brand, 2007;White et al, 2010).…”

-Passage performance of brown trout (Salmo trutta), Iberian barbel (Luciobarbus bocagei), and northern straight-mouth nase (Pseudochondrostoma duriense) was investigated in a vertical slot fishway in the Porma River (Duero River basin, Spain) using PIT telemetry. We analysed the effects of different fishway discharges on motivation and passage success. Both cyprinid species ascended the fishway easily, performing better than the trout despite their theoretically weaker swimming performance. Fishway discharge affected fish motivation although it did not clearly influence passage success. Observed results can guide design and operation criteria of vertical slot fishways for native Iberian fish. Key-words:Iberian fish / vertical slot fishway / fish passage / motivation / transit time Résumé -Aptitude au passage de la truite, Salmo trutta, et de deux cyprinidés ibériques, le barbeau ibérique, Luciobarbus bocagei, et le nase à bouche droite, Pseudochondrostoma duriense dans une passe à poissons à fentes verticales. La performance de passage de la truite (Salmo trutta), du barbeau ibérique (Luciobarbus bocagei), et du nase à bouche droite (Pseudochondrostoma duriense) a été étudiée dans une passe à fentes verticales dans la rivière Porma (bassin de la rivière Douro, Espagne) en utilisant la technologie PIT. Nous avons analysé les effets de différents débits dans la passe à poissons sur la motivation et la réussite de passage. Les deux espèces de cyprinidés montaient la passe facilement, étaient plus performantes que les truites, malgré leur performance de nage théoriquement plus faible. Le débit dans la passe affectait la motivation des poissons bien qu'il n'ait pas influencé clairement le succès de passage. Les résultats observés peuvent guider dans les critères de conception de passes à fentes verticales pour les poissons indigènes.

“…The swimming ability of fishes is commonly measured in a laboratory setting where a fish is forced to swim against a current with a known velocity, often generating estimates of critical swimming speed or estimates of time to fatigue (e.g., Peake 2008). Knowledge of the swimming ability of different fishes has been used to identify potential velocity barriers (Peake et al 1997a(Peake et al , 1997b) and generate models for use in the evaluation of different fishway passage facilities (Haro et al 2004), thus informing biological design criteria (Rodriguez et al 2006;Katopodis and Gervais 2012). Physiological methods such as muscle and blood biochemistry and respiratory energetics (e.g., metabolic rate, aerobic capacity) have been identified as useful ways to measure the physiological consequences of fishway passage (e.g., Connor et al 1964;Dominy 1971;Cocherell et al 2011;Roscoe et al 2011;Pon et al 2012).…”

Our understanding of biological criteria to inform fish passage design is limited, partially due to the lack of understanding of biological motivators, cues, and constraints, as well as a lack of biological performance evaluations of structures once they are built. The Vianney-Legendre vertical slot fishway on the Richelieu River, Quebec, Canada, passes large numbers of migrating redhorse (Moxostoma spp.) upriver to spawning grounds each year. We evaluated the physiological capacity and relative swimming ability of three redhorse species (Moxostoma anisurum, Moxostoma carinatum, Moxostoma macrolepidotum; silver, river, and shorthead redhorse, respectively) to determine how these biotic factors relate to variation in fishway passage success and duration. Shorthead redhorse had higher maximum metabolic rates and were faster swimmers than silver and river redhorse at their species-specific peak migration temperatures. Blood lactate and glucose concentrations recovered more quickly for river redhorse than for silver and shorthead redhorse, and river redhorse placed second in terms of metabolic recovery and swim speed. Interestingly, fish sampled from the top of the fishway had nearly identical lactate, glucose, and pH values compared to control fish. Using passive integrated transponders in 2010 and 2012, we observed that passage success and duration were highly variable among redhorse species and were not consistent among years, suggesting that other factors such as water temperature and river flows may modulate passage success. Clearly, additional research is needed to understand how organismal performance, environmental conditions, and other factors (including abundance of conspecifics and other comigrants) interact with fishway features to dictate which fish will be successful and to inform research of future fishways. Our research suggests that there may be an opportunity for a rapid assessment approach where fish chased to exhaustion to determine maximal values of physiological disturbance are compared to fish sampled from the top of the fishway, which could reveal which species (or sizes of fish) are approaching or exceeding their physiological capacity during passage.

“…The baffles were so shaped that part of the flow was turned back upstream to create recirculation regions in the pools where the fish would rest before ascending the fishway through the slots using their burst speed [10]. Water runs downstream through a series of vertical slots from one pool to the next; the water flow forms a jet at the slot and the flow energy is dissipated by jet mixing in the pools [11].…”

Abstract:The characteristics of the flow in vertical slot fishway depend mainly on the specific pool design, such as the geometry of the pool. We present the results of a study on comparison between four different designs of vertical slot fishways. The results indicated that central baffle cannot cut down the value of the velocity substantially, but it can stabilize the flow pattern, and it can make energy dissipation uniform. Simultaneously, slope has significant impact on hydraulic characteristics like velocity and flow pattern in the fishway. Of the four designs studied, design 4 is recommended for practical use, in terms of velocity and flow pattern.
