“…The relationship between gill area, metabolic rate, and body mass in fish determines the typical growth pattern of the species (Archer et al, 2021). The daily average oxygen consumption rate and asphyxiation point of E. kishinouyei are higher than those of M. anguillicaudatus (Tsui et al, 2004), Epinephelus fuscoguttatus (Okomoda et al, 2020), and Acipenser baerii (Yuan et al, 2016), which are of similar size to E. kishinouyei. The vigorous aerobic metabolism and intolerance to hypoxia of E. kishinouyei may be associated with its long-term life in torrential environments.…”

Glyptosternoid fishes are distributed in the torrent environment of alpine canyons, where they often leave the water to climb on rocky cliffs. As one of the most primitive species of glyptosternoid fishes, Euchiloglanis kishinouyei was examined in the current study to analyze its gill microstructure and respiratory ability. We first found that the oxygen consumption rate was relatively high and negatively correlated with body mass, and that the average oxygen consumption at night was higher than during the day. The asphyxiation point of E. kishinouyei (5.05 ± 0.22 g) was about 1.93 mg/L. Subsequently, the surface morphology, gross gill tissue structure and ultra‐microstructure of gill lamellae were investigated by optical microscopy and scanning electron microscopy. The gills showed an overall trend of regression, with five pairs of gill arches in each gill cavity. The adjacent gill filaments were with large gaps, and the gill lamellae were thick. The gill filaments were closely arranged on the gill arches, their folded respiratory surface was highly vascularized with no tiny crest, while there were obvious tiny crests, grooves, pits, and pores on the non‐respiratory surface. The gill lamellae were closely embedded on both sides of gill filaments, which were composed of flat epithelial cells, basement membrane, pillar cells and mucous cells. The gill total respiratory area correlated positively with body mass and length, while the gill relative respiratory area correlated negatively with body mass. We comprehensively analyzed the gill microstructure and respiratory capacity of E. kishinouyei, to provide fundamental data for the adaptive evolution of the gill structures of bimodally respiring fishes and offer insights into further study on the accessory air‐breathing function of skin.

“…The formation of concentrations of various fish species, including sturgeon in the water areas of riverbed depressions, can be beneficial both from the point of view of shelter from predators in zones of increased turbidity (Wishingrad et al, 2014), and to save energy resources in the zones of low-velocity, which are formed in the presence of vertical vortex structures. It should be noted (Yuan et al, 2016;Duan et al, 2017) that individuals of the Siberian sturgeon have relatively high swimming performance and a relatively low coefficient of resistance due to the unique body shape, as well as a high ability to cope with oxygen deficiency, while individuals of this species, as well as individuals of sterlet, concentrate in riverbed depressions. Siberian sturgeon has a wide range of reaction rates, which allows it as a species to occupy vast territories and form life strategies inherent in populations inhabiting an environment characterized by different conditions (Ruban, 2019).…”

Using the modern hydroacoustic methods and the computerized software and hardware complex “AsCor”, the features of the distribution of fish of the Acipenseridae family in the lower reaches of the large transboundary river the Irtysh (Western Siberia) have been investigated: in the water area of the riverbed depression (turbulent flow) and control sections (laminar flow). The identification of sturgeon was carried out by the echometric method according to the shape of the swim bladder. It is shown that in the water area of the riverbed depression, increased density of fish is formed, the share of sturgeons being 4.9–5.8%. Among other fish species, the group of cyprinids always dominates. The significant excess of the average fish density in the riverbed depression, in contrast to the control, was 6–30 times. In the water area of the riverbed depression, the average fish density was 4,524, in the control sections 245–2,091 individuals/ha. The size structure of the group of sturgeon in the control sections was represented by individuals with body sizes less than 25–30 cm, and in the riverbed depression – by individuals of different sizes and ages with a body length to 35 cm. The water area of the riverbed depression is located in the meandering section of the river and is characterized by intense vertical vortex structures (whirlpools) and the presence of malfunctioning currents. Features of the hydrological characteristics of the riverbed depression are factors in the formation of aggregations of fish, since fish can use the energy of discrete vortices, low-velocity areas, and as a result, show preference for certain turbulence regimes.

“…Also, one field study of migration of representatives of sturgeon in North America conducted with the help of acoustic equipment showed (McElroy et al, 2012) that the representatives of this family can still minimize energy consumption by using low-speed areas during migration. When studying the physiology of juvenile Siberian sturgeon (Yuan et al, 2016), as well as for individuals of Chinese sturgeon (Cai et al, 2014), it was found that their individuals, due to the metabolic characteristics of the organism, have a high ability to recover the energy spent on movement in the stream. This feature explains the pattern of increase in the share of the group Acipenseridae and Lotidae in the structure of ichthyofauna from the shore zone to midstream, from 10.2-17.1%, and for almost all size classes.…”

In order to supplement the available information for the eco-hydraulic approach to designing fish passages, taking into account the taxonomic, dimensional structure, as well as taking into account the presence of predatory fish in the stream, the distribution of migratory fish of the boreal plain faunistic complex (Russian Federation) was studied. Three depth-velocity sections from the shore to the midstream were investigated: 5 m and 27.8 cm/s, 8 m and 44.4 cm/s, 11 m and 55.6 cm/s. Analysis of the migration distribution of fish showed that in the direction from the shore to the midstream, the proportion of representatives of Cyprinidae decreases from 41.8–24.3% and that of Percidae decreases from 25.0–18.4%. For individuals of two groups: the Acipenseridae and Lotidae, Coregonidae and Esocidae, patterns of distribution in the structure of migratory fish are opposite – their share increases with increasing speed and depth characteristics: 23.0–40.2% and 10.2–17.1%, respectively. An assessment of the dimensional structure revealed a feature of increase in the size range of fish from the shore to the midstream: the dominance of small individuals (<10 cm) in the shore area is replaced by the dominance of large fish (> 30 cm) in the area of higher speeds and depths. A significant difference in the distribution for all studied taxonomic fish groups between the shore and the midstream was shown. Thus, it has been established that for Cyprinidae during the migration period, the choice shifts in favour of minimizing energy costs, and the choice to avoid the risk of predation from individuals of the groups: Coregonidae and Esocidae, and also Percidae, shifts in favour of the former. The distribution of perch is influenced by the reduction of energy costs and the simultaneous avoidance of predation and cannibalism. For the fish group Acipenseridae and Lotidae, their predominance in the deeper area is due to their less developed visual orientation mechanism in the stream because they are bottom-living fish species.
