“…Thus, to quantify the efficacy of a fish pass system, the water velocity and the flow model must be compatible with the swimming capacity of the species of interest, allowing passage of all fish, and not only the best swimmers (Larinier, 2002b). The diverse hydrological characteristics along the Canal da Piracema, such as steep slopes, high water velocities, and waterfalls, among others, may prevent the passage of fish.…”

The Canal da Piracema at Itaipu Dam as a fish pass system

The Canal da Piracema is the longest (nearly 10 km) fish pass system in the world. The construction of this fish pass was somehow controversial, because it connected two distinct ichthyofaunistic provinces. This study evaluated the ichthyofauna present in the Canal da Piracema and the abundance and distribution of long-distance migratory fish species along this fish pass system (evaluated possible selectivity). The Canal da Piracema was shown to be difficult to sample because of its environmental heterogeneity: artificial ponds, ladders and nature-like fish pass. To solve this problem, we used several fishing gears, adequate for the several biotopes present (unstructured and structured littoral were sampled with seining nets and electrofishing; lentic were sampled with gillnets and longlines (deeper areas); and rapid water areas were sampled with cast nets). The ichthyofauna of the Canal da Piracema followed the pattern for South America and the Paraná River, with a predominance of Characiformes and Siluriformes. The most representative families were Characidae, Anostomidae, Pimelodidae and Loricariidae. We captured 116 species (17 were long-distance migratory) during the period studied. Small-sized species were predominant in unstructured and structured littoral areas, especially Bryconamericus exodon and Apareiodon affinis. The most abundant species was Hypostomus spp. in lentic areas, followed by Iheringichthys labrosus. Hoplias aff. malabaricus predominated in deeper lentic areas. Long-distance migratory species were abundant in rapid waters; they were Prochilodus lineatus and Leporinus elongatus. The sharp reduction in the number of species, including migratory ones, is an indication that the Canal da Piracema is selecting the species that ascend it. Therefore, the search for information on the efficiency of the various fish passes present in the Canal da Piracema is fundamental, to facilitate upward movements of fish. If this is reached, this polemic fish pass has the potential to contribute to the conservation of fish stocks in Itaipu Reservoir and upstream stretches, because of the presence of spawning and development (nurseries) areas for migratory species.O Canal da Piracema é considerado o maior sistema de transposição para peixes no mundo, com 10 km de extensão. A sua construção foi controversa, pois viabilizou a conexão entre duas províncias ictiofaunísticas distintas. Este trabalho buscou avaliar a ictiofauna presente no Canal da Piracema, a abundância e distribuição das espécies migradoras de longa distância ao longo deste sistema de transposição (indicação de seletividade). O Canal da Piracema mostrou-se difícil de ser amostrado, devido a sua elevada heterogeneidade ambiental: lagos artificiais, escadas e canais semi-naturais, sendo utilizados diversos aparelhos de pesca, adequados aos diversos biótopos (litoral não estruturado e estruturado, amostrados com redes de arrasto e pesca elétrica; lêntico, amostrado com redes de espera e espinhel (mais profundo); e águas rápidas, amostradas com tarrafa...

“…4). The correct estimation of water level distribution is vital to assess the performance of fishways, as from this, other variables which are directly related with fish preferences and swimming abilities (Larinier, 2002a(Larinier, , 2002b, such as volumetric power dissipation (VPD = r · g · DH · Q/(B · L · h 0 ), where r is the water density and B is the width of the pool) (FAO/DVWK, 2002; Towler et al, 2015) or maximum velocity in the crosswall (V max ¼ ffiffiffiffiffiffiffiffiffiffiffiffiffiffiffi 2·g·DH p ) (Rajaratnam et al, 1986;Larinier, 2002b) can be estimated. Therefore, this method will enable the analysis of the possible consequences in fish passage of different hydraulic scenarios and, thus, it will allow the preliminary evaluation of the passage and detection of possible problems during the whole hydrological period.…”

-Stepped fishways are the most popular solutions to enable the free movement of fish fauna through weirs and dams. Given the flow variation of rivers throughout the year, successful fish migration through stepped fishways relies on the accurate discharge calculation and their modeling under variable scenarios. This study aims to propose a general method for flow and water level calculation of stepped fishways, unifying different findings in specialized literature. To achieve this purpose, the relation defined by Villemonte is used and tested under laboratory and field case studies. This study shows that the hydraulic behavior of a wide range of stepped fishway typologies can be explained based on a single equation, as well as the need of calibration of the coefficients involved in this equation for different subtypes. Furthermore, the proposed method enables the water level modeling under variable boundary conditions, which in turns allows the analysis of stepped fishways hydraulic performance under different river scenarios. The comparison of the hydraulic parameters in the fishways with the physical capacities and preferences of fish will contribute to the fulfillment of their main objective: allow free movement of fish fauna.Keywords: discharge coefficient / flow measurement / vertical slot fishway / pool and weir fishway / nature-like fishway Résumé -L'approche de Villemonte : une méthode générale de modélisation de la performance uniforme et non uniforme dans les échelles à poissons. Les échelles à poissons sont les solutions les plus populaires pour permettre la libre circulation de la faune piscicole à travers les seuils et les barrages. Compte tenu de la variation de débit des cours d'eau tout au long de l'année, la migration réussie des poissons par ces passes à poissons repose sur le calcul exact de la décharge et sa modélisation dans des scénarios variables. Cette étude a pour but de proposer une méthode générale de calcul du débit et du niveau d'eau des échelles à poissons, synthétisant différents résultats de la littérature spécialisée. Pour atteindre cet objectif, la relation définie par Villemonte est utilisée et testée dans des études de cas en laboratoire et sur le terrain. Cette étude montre que le comportement hydraulique d'une large gamme de typologies de poissons en gradins peut être expliqué sur la base d'une seule équation, avec besoin d'étalonnage des coefficients impliqués dans cette équation pour différents sous-types. De plus, la méthode proposée permet de modéliser le niveau de l'eau dans des conditions aux limites variables, ce qui permet, à son tour, d'analyser la performance hydraulique des passes de poissons en escaliers selon différents scénarios de rivières. La comparaison des paramètres hydrauliques dans les passes à poissons avec les capacités physiques et les préférences des poissons contribuera à la réalisation de leur objectif principal : permettre la libre circulation de la faune aquatique.Mots-clés : coefficient de décharge / mesure de débit / passe à fentes vert...

“…Indeed, the sill block on the weir was likely designed to induce the jump on the concrete and thus prevent erosion and undercutting at the toe. However, fish-passage structures are designed to prevent the occurrence of jumps, given that hydraulic jumps can affect the behavior and physical ability of migratory fishes in negotiating and passing velocity barriers (Beach, 1984;Larinier, 2002;Haro and others, 2004 …”

AbstractRecent efforts to advance river connectivity for the Millstone River watershed in New Jersey have led to the evaluation of a low-flow gauging weir that spans the full width of the river. The methods and results of a desktop modelling exercise were used to evaluate the potential ability of three anadromous fish species (Alosa sapidissima [American shad], Alosa pseudoharengus [alewife], and Alosa aestivalis [blueback herring]) to pass upstream over the U
