“…The Vianney‐Legendre vertical slot fishway in the Richelieu River, Canada, has shown to be successful for passing a variety of fish species, including lake sturgeon (Marriner et al., 2016). The Denil fishways of the 63 diversion dams in the Big Hole River basin in southwestern Montana provide opportunities for Arctic grayling ( Thymallus arcticus ) and other fish for year‐round access to critical habitats (Triano et al., 2022). The nature‐based fishway installed at a low dam in Indian Creek, Canada, has proven effective for multiple fish species to traverse the dam (Steffensen et al., 2013).…”

River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and solute regimes, and the channel morphology. These alterations have detrimental effects on the quality and quantity of fish habitat and associated impacts on aquatic life. Indeed, dams have been implicated in the decline of numerous fishes, emphasizing the need for effective conservation measures. Here, we present a global synthesis of critical issues concerning the impacts of river damming on physical fish habitats, with a particular focus on key fish species across continents. We also consider current fish conservation measures and their applicability in different contexts. Finally, we identify future research needs. The information presented herein will help support sustainable dam operation under the constraints of future climate change and human needs.

“…If tagged fish are released downstream but not detected by any downstream telemetry system (e.g., Steffensen et al, 2013), AE and PE are zero and "excluded," respectively, rather than zero and zero, respectively, which is different from Bunt et al (2012Bunt et al ( , 2016. For example, in Triano et al (2022), 416 Thymallus arcticus (Salmoniformes, Salmonidae) were released into a pool. As observed, 335 fish entered the approach pool, 178 were attracted, 86 entered the fishway, and 79 successfully passed through.…”

Globally, fishways perform better when the target fish species are salmonids rather than non‐salmonids. In the past few decades, engineers and dam managers have attempted to identify an ideal fishway type that can fit all migratory orders. To determine a general rule for selecting fishway types, we classified all fish orders into two groups (salmonids and non‐salmonids) and analyzed the effect of different fishway types (i.e., nature‐like [NL], vertical slot [VS], pool and weir [PW], and denil [DL]) on upstream migration for both groups by conducting a meta‐analysis based on data from 64 studies of 76 fishways. The fishway performance was presented in terms of attraction efficiency (AE) and passage efficiency (PE). The results of a random‐effects model, including 257 and 299 estimates of AE and PE, respectively, showed fishway types only had a significant effect on AE for non‐salmonids. Technical fishways had a higher AE than NL fishways for salmonids, but were not applicable to non‐salmonids. The passage results of four fishway types indicated that the PW fishways exhibited the best performance for salmonids, but the poorest performance for non‐salmonids. Only DL fishways had a PE of over 50% for non‐salmonids, whereas all fishway types had that of over 60% for salmonids. Variations in the slope and length of VS fishways could significantly affect PE for both groups, however, the phenomenon for salmonids disappeared when merging all fishway types. Elevation changes had a significant effect only on the condition that salmonids passed through VS fishways. The results of this study play an important role in designing appropriate fishway types for different downstream fish fauna and can be better generalized by complementing quantitative evaluation studies of various fishways as much as possible.

ObjectiveOur aim was to determine the movement patterns of three abundant salmonids—Brown Trout Salmo trutta, Mountain Whitefish Prosopium williamsoni, and Rainbow Trout Oncorhynchus mykiss—in the Smith River watershed of Montana.MethodsWe tagged 7172 fish with passive integrated transponder (PIT) tags, monitored their movements past 15 stationary PIT arrays over 4 years, and located tagged fish between arrays by conducting mobile surveys.ResultMovement patterns varied seasonally, among species, and among locations. Movement was greatest in the middle portion of the watershed, which included a pristine main‐stem canyon and lower reaches of major tributaries. Fish rarely left the canyon, but movement into the canyon from other regions was common. Mountain Whitefish were most likely to move, and Brown Trout were least likely to move. Most fish travelled less than 10 km, but some fish travelled over 100 km. Distinct movement patterns were not evident; rather, a continuous spectrum of movement behaviors was apparent. Movements by Mountain Whitefish and Rainbow Trout increased during their spawning periods. Movements peaked when mean daily water temperatures were between 11.3 and 17.1°C.ConclusionMovements were diverse and probably contributed to metapopulation dynamics, population resiliency, and species diversity. Fish movements along stream networks connect populations across diverse landscapes, and therefore, protecting and restoring stream connectivity along inland streams such as the Smith River is critical to maintaining productive fish assemblages.
