“…Considerable effort has been made to mitigate the effects of river obstacles through the development of fish passes, which aim to facilitate the upstream and downstream migration of individuals around or through obstacles (Larinier, 1998;Guiny et al, 2005;Bunt et al, 2012). The efficiency of such structures is however often questioned; flow conditions such as water velocity and depth within the pass itself are not always conducive to upstream passage of fish (Thorstad et al, 2008;Noonan et al, 2012;Cooke & Hinch, 2013).…”

The behaviour of returning Salmo salar (Linnaeus, 1758) approaching, and attempting to pass low-head weirs remains relatively unknown. A radio telemetry array was created at a low-head weir to enable the behaviour of S. salar (n = 120) to be observed as they approached and attempted to pass the barrier. The majority of fish successfully passed the barrier on their first or second attempt, some individuals required 11 attempts prior to successful passage occurring. Mean delay at the barrier per fish was 47.8 h (±SD 132.0 h), range 15 min to 31 days. Passage success on a fish's initial attempt was significantly predicted by the amount of searching a fish undertook, fork length, and fat content. Fish were more likely to have a successful first passage attempt if it was smaller with a low fat content and exerted a greater effort in searching for a passage channel. Small-scale barriers cause delays and increased energy expenditure in migrating fish. Barriers may be creating an anthropogenic selection pressure for traits which enable passage success. The impact of a delay at a barrier and increased energy expenditure on reproduction and gonad development remains unknown but is likely to be negatively impacted by instream anthropogenic structures.

“…Passage success through upstream fishways depends primarily on two factors: i) the capacity of the fishes to find and enter the system, and ii) the capacity of the fishes to pass through the length of the system (Aarestrup, 2003;Bunt et al, 1999Bunt et al, , 2011Castro Santos & Haro, 2010). Although the efficiency of the Canal da Piracema has not been evaluated as a whole, various migratory species, but specially P. lineatus and L. elongatus are abundant in the Bela Vista River (Makrakis et al, 2007b).…”

“…Designed to mimic natural stream channels, the nature-like fish passages are widely thought to provide superior passage performance for a wide range of species and life stages (Wildman et al, 2002). These claims are largely unsubstantiated, however, and in many cases they perform no better (or even worse) than more technical designs (Bunt et al, 2011). The monitoring of the Canal da Piracema began in 2004, with the collection of data from its diverse segments (mainly with gill nets and circular casting nets), and with radiotelemetry.…”

The majority of the fish passages built in the Neotropical region are characterised by low efficiency and high selectivity; in many cases, the benefits to fish populations are uncertain. Studies conducted in the Canal da Piracema at Itaipu dam on the Parana River indicate that the system component designated as the Discharge channel in the Bela Vista River (herein named Canal de deságue no rio Bela Vista or CABV), a 200 m long technical section, was the main barrier to the upstream migration. The aim of this study was to evaluate the degree of restriction imposed by the CABV on upstream movements of Prochilodus lineatus and Leporinus elongatus, Characiformes. Fish were tagged with passive integrated transponders (PIT tags) and released both downstream and upstream of this critical section. Individuals of both species released downstream of the CABV took much more time to reach the upper end of the system (43.6 days vs. 15.9 days), and passed in much lower proportions (18% vs. 60.8%) than those tagged upstream of this component. Although more work is needed to differentiate between fishway effects and natural variation in migratory motivation, the results clearly demonstrate passage problems at the CABV.A maioria dos sistemas para transposição de peixes implantados na região Neotropical caracteriza-se por baixa eficiência e seletividade, em muitos casos com benefícios questionáveis para as populações de peixes. Estudos conduzidos no Canal da Piracema, localizado na barragem de Itaipu, rio Paraná, apontaram como principal barreira à migração ascendente o componente do sistema denominado Canal de deságue no rio Bela Vista (CABV), uma seção de escada com 200 m de extensão. Este estudo teve por objetivo avaliar o grau de restrição imposto pelo CABV aos movimentos ascendentes de Prochilodus lineatus e Leporinus elongatus, Characiformes. Os peixes foram marcados com Passive Integrated Transponders (PIT-tags) e soltos a jusante e a montante do CABV. Indivíduos de ambas as espécies de jusante do CABV levaram muito mais tempo para atingirem a extremidade superior do sistema (43,6 dias vs. 15,9 dias) e passaram em muito menor proporção (18% vs. 60,8%) do que os marcados a montante desse componente. Embora sejam necessários outros trabalhos para a distinção entre os efeitos do sistema de transposição de peixes e a variação natural da motivação migratória, os resultados demonstram claramente que existem problemas na passagem pelo CABV.

“…There is a strong interdependence among organisms within an ecosystem, and the extirpation of a species could alter the entire ecosystem energy flow and composition (Baxter et al, 2004). Successful passage for fishes of all life stages across barriers to migration is imperative to restore and maintain ecosystem function (Beechie et al, 2010;Bunt et al, 2012;Wohl et al, 2005). In-stream structures must operate within the physiological limits of a fish's swimming abilities, and understanding how fish respond to micro-hydrodynamic and macro-hydrodynamic conditions within a structure is necessary to effectively design for passage success (Williams et al, 2012).…”

EFFECTS OF WHITEWATER PARKS ON FISH PASSAGE:A SPATIALLY EXPLICIT HYDRAULIC ANALYSIS Whitewater parks (WWPs) provide a valuable recreational and economic resource that is rapidly growing in popularity throughout the United States. WWPs were originally thought to enhance aquatic habitat; however, recent studies have shown that the hydraulic conditions required to meet recreational needs can act as a partial barrier to upstream migrating trout and that WWP pools may contain lower densities of fish compared to natural pools. There is limited knowledge of the direct effects of WWPs on fish passage. Managers and policy makers are forced to review WWP designs and make permit decisions without sound scientific evidence. It is also difficult to make design recommendations for future WWPs and possibly retrofitting existing WWPs to allow for successful fish passage without improved understanding of the factors contributing to suppression of movement in WWPs. We describe novel approaches combining fish movement data and hydraulic results from a three-dimensional computational fluid dynamics model to examine the physical processes that limit upstream movement of trout in an actual WWP in Lyons, Colorado. These methods provide a continuous and spatially explicit description of velocity, depth, vorticity, and turbulent kinetic energy (TKE) along potential fish swimming paths in the flow field. Variation in the magnitude and distribution of velocity and depth relative to fish swimming ability is reflective of variation in passage success among WWP structures and size classes of fish. Logistic regression analyses indicate a significant influence of velocity and depth on limiting passage success and accurately predict > 86 percent observed fish movements. Relationships emerge at individual WWP structures that iii highlight unique hydraulic characteristics and their effect on passage success. The methods described in this study provide a powerful approach to quantify hydraulic conditions at a scale meaningful to a fish and mechanistically evaluate the effects of hydraulic structures on fish passage. The results of these analyses can be used for management and design guidance, have implications for fishes with lesser swimming abilities, and demonstrate the need to assess additional WWPs of various sizes.iv ACKNOWLEDGMENTS
