Special Issue Information

Dear Colleagues,

Fishways sensu lato are the most used solution to mitigate longitudinal connectivity problems caused by river barriers. There are multiple types of fishways  (nature-like, step pools, baffles, lifts, locks, etc.) and all aim to allow the free, safe movement of migratory fish through barriers without delay. However, today, there are still multiple unknowns (performance for less known species, ethohydraulics, attraction, bidirectional usage, etc.) that could deviate fishways from their objective and require more research and development.

New advances in ecology, behavior, and swimming performance of fish are guiding current designs to multiespecies fishways, with the goals of  lightening hydrodynamic requirements for fish (e.g., by naturalization, incorporating roughness, or other geometrical features), improving attraction/rejection to key locations, or proposing new fishway typologies (e.g. pumps, siphons or screws), among others. Regardless, fishway assessment using extended monitoring technologies (PIT-tags, radio tracking, fish counters, cameras, etc.), different hydraulic scenarios/conditions, and appropiate statistical analyses are a must to test, calculate their efficiency, and improve and validate these new approaches and devices. 

Therefore, this Special Issue is focused on advances and experiences in fishway design and assessment, considering both upstream and downstream fish migration, attraction and passage, innovative designs, fish behavior, and/or fish efficiency assessment. Field, laboratory, CFD, and case studies on fishways are welcome.

Fishways are essential hydraulic structures to ensure the migration of fish and other aquatic organisms in the area of cross structures in river systems. In this context, the present study focuses on vertical slot fishways with specific geometries and their discharge coefficients. A comprehensive data analysis was performed, aiming on the development of new fitting parameters in conjunction with their respective approaches for practical design procedures. In addition, validity ranges and parameter dependencies were defined. Using the new fitting equations, it is possible to determine accurate discharge coefficients to design functional strutures for a defined validity range. Results show that discharge coefficients are highly dependent on the basin geometry. Comparing newly developed fitting parameters have shown that investigated fitting equations can be used to determine discharge coefficients. However, it should be noted that newly developed fittings can only be applied in practice for the defined range of validity for investigated exemplary geometries. Full article

Enhancing river passability is considered a central part of the efforts to maintain fish population and achieving good ecological status, according to the EU Water Framework Directive (WFD). One commonly proposed approach to achieving this aim involves the creation of fishways. However, recent studies have shown that many of these fish passes are often lacking an optimal design with far reaching consequences for fish migration. Several promising new designs such as nature-like rock ramps, with uphill flow, have been recently developed. Such studies attempt to address these drawbacks by adapting several structure-related features (i.e., boulder size and shape and friction walls). In this study, we used a 2D computational fluid dynamic model to assess how the key hydraulic variables (water depth, velocity and turbulent kinetic energy) were impacted by different design elements of uphill flow fishways with different configurations. With regard to the standard boulder shapes and sizes, our results reveal that: (1) doubling the boulder sizes results in a decrease of turbulent kinetic energy in resting corridors of up to 33%; (2) the inclusion of small friction-walls in the ramp design increases uphill velocity in the intermediate corridors by up to 49%; (3) the trapezoidal shape of the boulder leads to the largest decreases in maximum velocity in the gaps (16%) and the largest increases in the uphill velocity in the resting corridors (180%). These results may allow us to optimise the uphill flow rock-ramp design to improve the passability of this type of fishways. Full article

This work aims to assess brown trout (Salmo trutta) passage through a free-flow pool-weir-type fishway with hydrodynamic notches and extreme water drops between pools. It consists of an old-school fishway design, commonly constructed in salmon rivers of Spain during the period of 1950–1980. To assess their performance, a field test was designed with confined trial conditions during the spawning migratory season. The mean water drop between pools was 0.65 m and the total water height considered for the trial was 11.8 m. The monitoring was carried out using PIT telemetry. The initial hypothesis, considering the fishway design and assessment guidelines, classified this structure as hardly insurmountable. Results showed an ascent success of 19% with a median transit time of 29.1 min/m of ascended height. Larger fish and fishway sections with lower values of volumetric power dissipation were related to a better performance in the passage. The results suggest that in certain circumstances, such as limited construction areas where other design or management options are difficult to implement (e.g., canyons), this type of fishway may be an alternative for the upstream passage of at least a small proportion of the brown trout population, although a selection effect is expected.

Barriers are an effective mechanism for managing invasive species, such as sea lamprey in the Laurentian Great Lakes but are detrimental because they limit the migration of desirable, native species. Fish passage technologies that selectively pass desirable species while blocking undesirable species are needed. Optical sorting tools, combined with newly developed computer learning algorithms, could be used to identify invasive species from high-resolution imagery and potentially isolate them from an assortment of the Great Lakes fishes. Many existing barriers lack fishways, and optical sorting may require fish to be dewatered for image capture. The Archimedes screw, a device originating from 234 BCE, offers the potential to continuously lift fish and water over low-head barriers or into an optical sorting device. To test the efficacy of an Archimedes screw and fish lifting to capture and pass Great Lakes fishes, we built a field-scale prototype and installed it at the Cheboygan Dam, Michigan in the USA in 2021. The fish lift safely transported 704 fish (688 of which were suckers (Catostomidae)) in 11 days. The passage of the suckers through the fish lift increased with the water temperature and attraction flow. There were no observed injuries in the transported fish or mortalities in a subset of suckers held post-transport. Full article
