“…Previous research has identified three swimming speeds associated with upstream migration: induced swimming speed (Cai et al, 2018), critical swimming speed (Nelson et al, 2002; Plaut, 2001), and burst swimming speed (Wardle & He, 1988). These velocities correspond to distinct swimming states, namely, current sensing, cruising, and bursting against the current (Cai et al, 2018; Cai et al, 2019; Liao et al, 2022; Wardle & He, 1988). These swimming abilities have practical applications in the design and construction of fish passage facilities.…”

Dam construction alters the hydrodynamic conditions, consequently impacting the swimming behavior of fish. To explore the effect of flow hydrodynamics on fish swimming behavior, five endemic fish species in the upper Yangtze River basin were selected. Through high‐speed video visualization and computer analysis, these species' swimming patterns under different flow velocities (0.1–1.2 m/s) were investigated. The kinematic and morphological characteristics of the fish were presented. The principal component analysis was used to analyse the main factors influencing the swimming ability of fish and to determine the correlation coefficients among fish behavior indicators. Fish exhibited three different swimming patterns under different flow velocities. Low velocity (0.1–0.3 m/s) corresponds to free motion, middle velocity (0.4–0.7 m/s) corresponds to cruising motion, and high velocity corresponds to stress motion (0.8–1.2 m/s). The fish kinematic index curves were obtained, and four of five fish species showed two extreme points, which means the optimal and adverse swimming strategies can be determined. With the increase in flow velocity, the tail‐beat frequency showed an increasing trend, whereas the tail‐beat angle and amplitude showed a decreasing trend. Morphological and kinematic parameters were the two main indexes that affect the swimming ability of fish, which accounts for 41.9% and 26.9%, respectively.

“…Compared with four carps of other body lengths reported (in Table 6), the critical swimming speed was higher for the longer fish. This may be that the relative values of fish surface area and muscle weight scales increased in proportion with the increased fish size, and the propulsion power of fish overcoming the body weight is inversely proportionate to the size of body length [15,23,24].…”

Swimming Performance of Four Carps on the Yangtze River for Fish Passage Design

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.

“…He revealed that the impacts of turbulence on fish locomotion rely on the turbulence scales of flow. Furthermore, with more ecological hydraulic structures ( e.g ., fishway) being constructed, multiple studies have focused on swimming performance of fish and fishway design (Cai et al ., 2019; Ficke et al ., 2011; Link et al ., 2017). Nevertheless, few studies investigate how fish may respond to flow with aquatic vegetation, which usually appear as vegetation patches.…”

Flows in river habitats are characterized by unsteady turbulence due to the existence of woody debris, boulders and vegetation. As a representative aquatic species, fish is important for the riverine ecosystems, with its complex behavioural responses to turbulent flows. Previous studies investigated the fish–vortices interaction with vortex streets by placing objects with simplified geometries centred at the flow. Nonetheless, complex river morphology in natural rivers results in much more spatially heterogeneous flows due to randomly distributed obstructions. Thus, a semi‐circular cylinder patch located on one side of the flume is used to mimic a vegetation patch at the riverbank. The patch varies in diameter (D0 = 16, 20 and 24 cm) and density (φ = 0.04 and 0.1), whereas the flow velocity is fixed at 25 cm s−1. Fish are observed to swim in three typical patterns, which are “swim around” (pattern 1), “spill” (pattern 2) and “swim through” (pattern 3). For flow with a dense patch, all three patterns are recorded, but only patterns 1 and 2 are observed in sparse patches. It is noticed that in patterns 1 and 2, fish prefer to hold place in zones of low velocity and low turbulence. Moreover, variations in patch diameter have little influence on pattern selection. Results showed that tail beat amplitude (TBA*) in each zone displayed more variations compared with tail beat frequency (TBF). In addition, Spearman's rank tests revealed that TBA* is affected by none of the four hydrodynamic variables (U,ustd,τxy,Ωz), whereas flow velocity imposes the most influence on TBF. Both diameter and density of the patch displayed no significant influence on TBA* and TBF.
