“…Fishways can be located at sites where the flow is limited by operational constraints (e.g., hydropower production) or where large flow reductions can naturally occur [68,69]. It is thus important to determine the discharge needed to operate the fishway, in such a way that hydraulic conditions compatible with fish requirements are ensured as well as hydropower production.…”

“…In the former, the VSF, which encompassed nine pools (2.4 m × 1.6 m) separated by 20 cm wide slots, was tested with bottom substrates. The remaining studies (n = 7, 87.5%) were all conducted under laboratory conditions, with the VSF having been tested for slopes ranging from 7.5% to 8.5%, with either 6 (n = 5, 71.4% [69,76,[93][94][95]) or 11 (n = 2, 28.6% [80,90]) pools (1.85 m-1.9 m × 1.0 m-1.5 m), separated by 10-and 27-cm wide slots, respectively. Of these lab studies, two (28.6%) [93,95] employed a variant of VSF, the multi-slot fishway (MSF [97]), featuring two consecutive slots per pool.…”

“…Experimental studies focusing on the passage performance of barbel under two slot configurations were also conducted [69]: C1-slot configuration with both a central and lateral baffle and C2-slot configuration with only a lateral baffle, based, respectively, on Designs 1 and 11 proposed by Rajaratman et al [20], with both configurations being similar in slope, pool length (L) and width (B), slot width (b), head drop between the pools (∆H), and the mean water depth in the pool (d). The results show no significant differences in the number of upstream movements, total number of successes, time to first successful negotiation, and time to enter the fishway (entrance time).…”

The Iberian barbel (Luciobarbus bocagei) is one of the most common cyprinids in the Iberian Peninsula, whose migratory routes are often hampered by anthropogenic barriers. Fishways might be an effective mitigation measure if they integrate designed operational characteristics that account for the biomechanical requirements of this species. Understanding the flow conditions inside the fishway, and how barbel responds to the hydrodynamics of the flow is imperative to improve free migratory routes with minimum energetic cost associated. Herein, we analyze and synthesize the main findings of research on pool-type fishways for upstream passage of the Iberian barbel and derive recommendations of design criteria for pool-type fishways for this species and others of similar biomechanics capacities. Ultimately, we identify research needs to improve upstream passage of this species.

“…The general question is whether a given bed slope configuration can determine hydrodynamic conditions affecting fish pass efficiency. Field experiments on the ecological efficiency of VSF found in the literature (de Freitas Duarte et al, ; Laine, Kamula, & Hooli, ; Romao et al, ; Stuart & Mallen‐Cooper, ; Silva et al, ; Thiem et al, ) show that for bed slopes lower than 5%, fish passage efficiency is generally higher than 30% and in certain cases higher than 60% (de Freitas Duarte et al, ; Stuart & Mallen‐Cooper, ; Silva et al, Thiem et al, ), whereas it falls below 30% at higher slopes (Laine et al, ; Romao et al, , 2018; Quaresma et al, ). Based on experiments in non‐uniform flow conditions, fish were found making broader use of the fishway pool in scenarios with lower water drops, which are highly correlated with regions of overall lower turbulence and velocity magnitude (Fuentes‐Perez et al, ).…”

Vertical slot fishways (VSFs) are the most efficient and least selective typology of technical fish passage, due to their ability to remain effective even when significant upstream and/or downstream water level fluctuations occur. Fishway construction costs can be reduced by increasing its bed slope, but this affects the flow field inside the pools, with higher head drops between the basins, as well as turbulence levels and flow velocities, which may affect fish passage. In light of this, a VSF was investigated by 3D numerical simulations to identify the possible effects of the bed slope (using values from 1.67% to 10%) on the flow field and subsequent implications for fish passage. A particular focus was devoted to cyprinind species, but the results can be extended to other species of similar swimming abilities and, therefore, be applicable to multispecies rivers. Flow velocity and turbulence values such as turbulent kinetic energy and Reynolds stresses were analysed from a fish passage perspective in relation to threshold values derived from previous studies. Pool areas where turbulence values are compatible with fish ability and behaviour were quantified. Maps of the location of fish-friendly zones in the VSF pools were produced and can constitute a reference for practical applications in fishway design. The flow field generated with bed slopes lower than 6.67% is more compatible with fish swimming capabilities, because it exhibits a predominantly 2D behaviour and more suitable hydraulic conditions, whereas at higher slopes, turbulence levels in the pools increase.

“…Short distance movements (local) are generally related to changes in resources availability (Albanese et al, 2004), like food or refuge (Gowan, Fausch, 2002;Gowan, 2007), predation risk (Roberts, Angermeier, 2007), or to abiotic conditions like salinity, stream flow Romão et al, 2017), and dissolved oxygen (Branco et al, 2016). Local movements can also be related to ontogeny, being an important life-history trait for several species (Winemiller, Jepsen, 1998).…”

Fish movement in an Atlantic Forest stream

Given the importance of fish movement to the dynamics and maintenance of stream dwelling fish communities from the Atlantic Forest, we analysed patterns of fish movement in a coastal stream from Southeastern Brazil, using mark-recapture technique. Displacement distance of each species were presented and discussed considering seasonal (rainy and dry) and body size patterns. We marked 10 species along the stream and recaptured 440 (34.6%) of the 1,270 marked fishes. The species with significant number of upstream moving individuals were Astyanax janeiroensis, Characidium interruptum, Astyanax hastatus, Parotocinclus maculicauda and Awaous tajasica. Only Pimelodella lateristriga presented significant differences between resident and moving individuals. Characidium interruptum and A. tajasica demonstrated greater downstream and upstream movement, respectively, moving up to 2,100 m. Even after controlling for species identity we found no significant correlation between fish length and individual displacement distance. Fishes moved longer distances during the rainy season, in accordance to the breeding season. Patterns of fish movement were in agreement to life-history traits of many of the studied species and can be reflecting specific behaviour and morphologies.Keywords: Coastal stream, Migration, Reproduction, Stream dwelling fish.Considerando-se a importância do movimento de peixes para a dinâmica e manutenção das comunidades de peixes de riachos da mata Atlântica, nós analisamos os padrões de movimento de peixes de um riacho costeiro do sudeste do Brasil, usando a técnica da marcação e recaptura. Avaliamos a distância do deslocamento de cada espécie e também se os padrões de movimento apresentavam alguma relação com a estação do ano (chuva e seca) e o tamanho do corpo. Marcamos 10 espécies ao longo do riacho e recapturamos 400 (34.6%) dos 1.270 peixes marcados. As espécies com número significativo de indivíduos se movendo para cima foram Astyanax janeiroensis, Characidium interruptum, Astyanax hastatus, Parotocinclus maculicauda e Awaous tajasica. Apenas Pimelodella lateristriga apresentou diferenças significativas entre os indivíduos residentes e em movimento. Characidium interruptum e A. tajasica foram as espécies com maior movimento tanto para baixo como para cima, respectivamente, se movendo até mais de 2.100 m. Mesmo após controlar a identidade das espécies, não registramos correlação significativa entre o comprimento e a distância individual do deslocamento. Registramos maiores densidades de peixes se movendo para montante durante a época de chuvas, em coincidência com a estação reprodutiva. Os padrões de movimento registrados estão de acordo com os componentes da história de vida de várias das espécies estudadas, e podem estar refletindo componentes morfológicos e comportamentais específicos.Palavras-chave: Migração, Peixes de riacho, Riacho costeiro, Reprodução.
