“…Treatments ranged from 8 to 210 mm Hg (SD ¼ 18 mm Hg) and were highly variable, fluctuating two to three times more than the variation experienced with our system. Another experiment, employing a design similar to ours, mixed a supersaturated water source with a saturated one after injecting air into a pressurized vessel, maintaining treatment levels of 4-75 mm Hg (SD ¼ 10 mm Hg; Krise and Smith 1991). This variation was similar to our maximal variation at the highest treatment but roughly twice that observed under similar DPs in our oxygen enrichment and chronic studies.…”

Gas bubble disease caused by supersaturated conditions is generally well understood for commercially important freshwater species, such as salmon and trout, but very little is known about impacts to marine finfish culture. We developed a relatively simple, low‐cost apparatus to expose juvenile white seabass Atractoscion nobilis and striped bass Morone saxatilis to multiple gas saturation levels simultaneously. We found that the system was capable of operating under different temperatures and accommodating a range of juvenile fish sizes. Gas saturation treatments were maintained by mixing a supersaturated seawater source with a saturated one. The supersaturated seawater source was created by reducing pressure of an air‐ or oxygen‐equilibrated water source maintained at a pressure of 623.2 mm Hg. The saturated seawater source was achieved by degassing seawater using a packed column. By mixing these two water sources manually by use of needle valves, differential gas pressures (ΔP) ranging from 0.0 to 167.2 mm Hg were maintained. The control treatment level ranged from −35.7 to 0 mm Hg and was maintained using a vacuum degasser. Oxygen‐nitrogen (O2:N2) ratios ranged from 0.83 to 1.41. Temperature within the experiment was computer controlled. The supersaturation apparatus operated very effectively and delivered treatment levels that were stable and significantly different from one another throughout all trials.

“…In the only study we are aware of (Counihan et al 1998), white sturgeon embryos were resilient to GBT but the vulnerability of sturgeon larvae varied with the stage of development (Counihan et al 1998). This is consistent with salmonids, whose embryos are resilient to GBT (Alderdice and Jensen 1985), larvae experience some level of GBT, and juvenile and adults are the most sensitive to GBT (Krise and Smith 1991). White sturgeon feed and live near the deep areas of rivers (Hildebrand et al 1999) where depth has been shown to provide protective effects to GBT (Antcliffe et al 2002;Pleizier et al 2020a).…”

Hydroelectric dams are an important source of electricity globally, but they can also cause total dissolved gas (TDG) supersaturation in rivers. Total dissolved gas supersaturation can harm fish through a condition called gas bubble trauma (GBT). Gas bubble trauma has been studied primarily in salmonids, such as rainbow trout and steelhead salmon (Oncorhynchus mykiss), but seldomly in non-salmonids like white sturgeon (Acipenser transmontanus). We assessed the vulnerability of juvenile rainbow trout (<1 year old), juvenile kokanee (Oncorhynchus nerka) (<1 year old), and two ages of white sturgeon (<1 year old and 3+ year old) to GBT. Bubble formation and the time to 50% loss of equilibrium (LOE) was quantified during exposure to nominal levels of 100, 115, 120 and 130% TDG. We predicted that all three species would show similar times to 50% LOE at a given TDG level. However, time to LOE was longer, the proportion of fish with external symptoms of GBT was lower and the proportion of fish with bubbles in the gills was higher or lower (dependant on age) in white sturgeon relative to rainbow trout and kokanee at a given TDG. The physiological basis for the difference is not known. However, it is important to consider species specific differences in TDG sensitivity in the conservation of vulnerable species
