“…black carp: The fish with different body lengths have different fish swimming abilities. Some studies have reported that they were the linear correlation between fish swimming speed and body length [16,[20][21][22]. In this study, it can be seen from Figure 3 that the swimming speed (critical and burst swimming speed) (m/s) of the four carps increased with the increased body length, and the relative (critical and burst) swimming speed (BL/s) decreases with body length, which is similar to previous research results.…”

Anthropogenic engineered structures alter the local ecological connectivity of river and survival habitat of native fishes. The swimming performance is critical for establishing fish passage or fish habitat. This study evaluated the swimming performance of four carps (black carp, grass carp, silver carp and bighead carp) with smaller body lengths (1.0–9.0 cm) in a swimming flume. The results showed that the critical and burst swimming speed (m/s) of the four carps increased with the increased body length, and the relative (critical and burst) swimming speed (the critical and burst swimming speed divided by the body length, BL/s) decreases with body length. The critical and burst swimming speed of each species at two individual length groups (1.0–5.0 cm, 5.1–9.0 cm) was significantly different (p < 0.05), and the water velocities in fish passage should be less than the fish burst swimming speed. The results further provided the swimming performance data of juvenile carps and provided technical reference for the construction of fish passage and the restoration of ecological habitat.

“…The water velocity was initially set at 1 BL/s, and increased by specified time intervals (∆t) until the fish ceased swimming for 5s and was considered exhausted [7,15,16]. U crit and U burst were identified by conducting increasing velocity tests and were calculated using the formula described by Brett (1964), as follows:…”

“…As has been previously reported in several studies of freshwater sh(Cai et al 2020;Starrs et al 2011;Zupa et al 2015), at a given temperature, critical velocity increased as the studied species L T increased. There was a linear relationship between critical velocity and L T , similar to what was reported byHou et al (2018). Thus, sh L T is relevant when estimating critical velocity (Table5and 6), increasing at larger sizes as has been observed in many studies(Mateus et al.…”

This study evaluated the effect of fish total length (LT) and three water temperatures (10, 15 and 20 ºC) on the critical swimming speed (Ucrit) of the species Percilia irwini (2.9 – 6.3 cm LT), Cheirodon galusdae (3.4 – 5.5 cm LT), and Trichomycterus areolatus (4.0 – 6.3 cm LT). An Ucrit estimation model was constructed for each species as a function of temperature and size. The results showed mean Ucrit for P. irwini of 44.56, 53.83 and 63.2 cm s-1 at 10, 15 and 20 ºC, respectively: 55.34, 61.74 and 70.05 cm s-1 for C. galusdae and 56.18, 63.01 and 71.09 cm s-1 for T. areolatus. Critical velocity depended on the interaction between species, body length and water. The swimming performance increased significantly with rising temperature in all three species. The velocity also increased with greater LT. After controlling for LT, velocity also increased with higher temperature in the three species. This research is relevant to small fish species that require conservation measures.

“…The relationships between the escape speed of fish and other classic fish swimming speeds (e.g., critical swimming speed, U c and burst swimming speed, U b ) measured in swim chambers or open channels (Katopodis, Cai, & Johnson, 2019; Katopodis & Gervais, 2016) may assist in quantifying the ability of fish to escape accelerating flows. The data of U c and U b were obtained using the stepped‐velocity and fixed‐velocity (Hou et al, 2018) tests, respectively, in a Loligo System (http://www.loligosystems.com). The critical swimming speed was measured by gradually increasing the water velocity in 20‐min time step and the burst swimming speed was measured at the time to fatigue for a fixed water velocity.…”

The migration corridors in regulated rivers lead downstream fish migrants, particularly juveniles to pass through water infrastructure. Accelerating flow, experienced by fish, might trigger avoidance behaviour and then influence the downstream migration efficacy. It is essential to understand the causes of avoidance behaviour exhibited by downstream migratory fish in accelerating flow. In this study, the effect of three different accelerating flows on the downstream migration behaviour of Schizopygopsis younghusbandi (S.Y) was investigated using a constriction wedge in a circulating flume. The results showed that some fish (30%, 23%, and 39% under low, medium, and high flow conditions, respectively) repeatedly attempted to burst upstream with positive rheotaxis prior to successful passage downstream. Under the low‐, medium‐, and high‐accelerating levels, the average fish swimming speeds were 89.19, 91.28, and 111.94 cm/s, respectively; these values were close to the critical swimming speed (110.42 cm/s) of the target fish. The water velocities at the fish avoidance points were centrally distributed at approximately 73.03 cm/s. Regarding turbulence, the results exhibited that the S.Y generally responded to a discrete range of <50 cm2/s2 of turbulent kinetic energy and < 2 N/m2 of the horizontal component of the Reynolds shear stress (RSSxy). Also, the fish that exhibited avoidance behaviour were not centrally distributed in the lateral and longitudinal velocity locations, where there was an abrupt change in the gradient. This study highlighted the impact of accelerating flow on the downstream fish migration behaviour of a cyprinid. Furthermore, this study quantified the hydraulic factors that triggered this avoidance. Thus, it provided experimental support for optimizing the design of the hydraulic factors for downstream fishways.
