“…The pathology of GBD, in non-experimental studies, is described in both living and dead fish as gas bubbles and hemorrhages in fins 28 , 32 , 34 , 40 , as well as gill congestion and hemorrhages, along with exophthalmia 31 , 41 . In addition, microscopic lesions such as gas bubbles in blood vessels, hemorrhages, and congestion in different tissues, attributed to GBD, have been described 42 , 43 .…”

“…Clinical signs have been observed in live fish inhabiting these supersaturated waters, such as loss of buoyancy and erratic swimming, along with pathological signs such as gas bubbles in eyes and fins 22 . Fish experimental studies on GBD have mainly focused on the survival of the different fish species and life stages at different TDG values 21 – 34 .…”

Decompression sickness (DCS) is a clinical syndrome caused by the formation of systemic intravascular and extravascular gas bubbles. The presence of these bubbles in blood vessels is known as gas embolism. DCS has been described in humans and animals such as sea turtles and cetaceans. To delve deeper into DCS, experimental models in terrestrial mammals subjected to compression/decompression in a hyperbaric chamber have been used. Fish can suffer from gas bubble disease (GBD), characterized by the formation of intravascular and extravascular systemic gas bubbles, similarly to that observed in DCS. Given these similarities and the fact that fish develop this disease naturally in supersaturated water, they could be used as an alternative experimental model for the study of the pathophysiological aspect of gas bubbles. The objective of this study was to obtain a reproducible model for GBD in fish by an engineering system and a complete pathological study, validating this model for the study of the physiopathology of gas related lesions in DCS. A massive and severe GBD was achieved by exposing the fish for 18 h to TDG values of 162–163%, characterized by the presence of severe hemorrhages and the visualization of massive quantities of macroscopic and microscopic gas bubbles, systemically distributed, circulating through different large vessels of experimental fish. These pathological findings were the same as those described in small mammals for the study of explosive DCS by hyperbaric chamber, validating the translational usefulness of this first fish model to study the gas-bubbles lesions associated to DCS from a pathological standpoint.

“…Symptoms of GBD mainly include exophthalmia, hemorrhage (Jensen et al, 1986; Meekin & Allen, 1974; Stroud et al, 1975), and bubbles on the head and in the gills and fins (Fan et al, 2020; Marsh & Gorham, 1905; Meekin & Allen, 1974). Additionally, fish with GBD usually exhibit abnormal behaviors, such as loss of balance, back‐and‐forth swimming, excessive opercular ventilation, and an apparent escape response (Chen et al, 2012; Ji et al, 2021; Krise, 1993). These abnormal behaviors may accelerate the fatigue of fish and reduce their swimming ability (Cao et al, 2021).…”

When dams discharge floodwaters, the river downstream often becomes supersaturated in total dissolved gases (TDG) and contains high volumes of suspended sediments (SS). Supersaturated TDG and high SS concentrations in water may affect fish physiologically in ways that manifest in swimming performance. Despite increasing awareness of the separate effects of TDG supersaturation and SS, knowledge about their synergistic effects remains unknown. To explore the interactive effects of TDG and SS on the swimming performance of bighead carp, the juveniles were exposed to 100, 110, 115, 120, 125, 130, 135 and 140% TDG supersaturated water with SS concentrations of 0, 50, 100 and 150 mg/L, respectively, and the critical swimming ability speed (Ucrit) and burst swimming ability speed (Uburst) were measured. The results indicated that the swimming ability (Ucrit and Uburst) decreased when TDG levels and SS concentrations increased. TDG and SS did not interact significantly to decrease both Ucrit and Uburst. In contrast, exposure to TDG alone significantly decreased both Ucrit and Uburst, whereas exposure to SS alone only decreased Uburst. In addition, our results suggested that there was a negative linear relationship between TDG and fatigue time. Swimming ability can decline significantly due to high TDG levels (> 130%). Therefore, high TDG levels (>130%) should be restricted during reservoir operation to prevent the stress caused by TDG.This article is protected by copyright. All rights reserved.

“…(2019) found that as TDG levels increased from 100% to 135%, the hatchability of Chinese suckers decreased from 78.25% to 67.50%. At 130% and above TDG levels, silver carp ( Hypophthalmichthys molitrix ) exhibited reduced avoidance behaviour (Ji et al., 2021). The survival rates of sliver carp and common carp decreased when TDG levels rose (Deng et al., 2021).…”

Discharged floods containing a large amount of suspended sediment (SS) can lead to total dissolved gas (TDG) supersaturation downstream of dams. The swimming ability of fish may be affected by TDG supersaturation and excessive SS. However, previous studies focused only on the separate effects of TDG and SS, ignoring their combined effects. In this study, juvenile rock carp and grass carp were selected to assess the interactive effects of TDG and SS on fish swimming ability. A totally crossed two‐factorial design (six TDG levels: 100%, 115%, 120%, 125%, 130% and 135%; four SS concentrations: 0, 50, 100 and 150 mg/L) was set, and the critical swimming speed (Ucrit) and the burst swimming speed (Uburst) were measured. The findings indicated that the swimming abilities (Ucrit and Uburst) of both fish species decreased with increasing TDG levels and SS concentrations. Separate exposure to TDG significantly decreased the swimming abilities of the two fish species, whereas separate exposure to SS decreased only the swimming abilities of juvenile grass carp. Juvenile rock carp exhibited weaker swimming abilities than juvenile grass carp in TDG‐supersaturated water. Additionally, the interaction between TDG and SS reduced the swimming abilities of juvenile rock carp and grass carp compared with a separate effect, but this reduction was significant only for the Ucrit of juvenile grass carp. This study demonstrates that TDG‐supersaturated water containing SS during flooding may result in fish failure through fishways.
