“…The decrease in the number of movements during exposure to hypoxia is probably a strategy for saving energy during extended exposure to hypoxia (Nilsson et al, 1993). By contrast, other studies have reported an increase in activity with moderate hypoxia exposure in adult sand goby Pomatoschistus minutus (Petersen and Petersen, 1990), adult brook trout Salvelinus fontinalis (Tang and Boisclair, 1995), and juvenile guppies Poecilia reticulata (Weber and Kramer, 1983). These responses are likely escape responses in fish that often encounter localized hypoxic zones (Petersen and Petersen, 1990).…”

SUMMARY We investigated the influence of oxygen demand (developmental stage) and supply (hypoxia, water flow rate, the chorion and body movements) on the oxygen concentration within the boundary layer next to the chorion of embryos or skin of larvae of rainbow trout (Oncorhynchus mykiss). Oxygen microelectrodes were used to measure dissolved oxygen (DO) within the boundary layer of trout embryos and larvae. As the embryos and larvae developed, the DO gradient and the thickness of the boundary layer increased. The DO concentration within the boundary layer next to the chorion or skin surface decreased as the DO concentration in the free-stream water decreased. A decrease in water flow rate increased the magnitude of the gradient and thickness of the boundary layer. In normoxia, the DO in the perivitelline fluid inside the chorion was 16±3.0% saturation at 31 days post fertilization, indicating that the chorion was a significant barrier to oxygen diffusion. The number of body movements did not change when embryos were exposed to hypoxia before hatching, but after hatching, hypoxia resulted in a decrease in body movements of the larvae. Taken together, our data indicate that the oxygen boundary layer around trout embryos and larvae depends on both the oxygen demand and supply. The factors that significantly impacted boundary layer oxygen were developmental stage, free-stream oxygen levels, water flow rate, and the presence of the chorion.

“…The role of fish surfacing behaviour is to access the more oxygen-rich surface layer to reduce the negative effects of hypoxia (Kramer 1987). Access to the water surface has been shown to reduce mortality in guppy (Poecilia reticulata; Weber & Kramer 1983) and reduce the negative effects on growth rate in mummichog (Fundulus heteroclitus; Stierhoff et al 2003) owing to hypoxia exposure. Therefore, denying inanga access to the surface water was the most likely cause of difference between studies.…”

The acute lethality of low dissolved oxygen (DO) was examined in laboratory studies using several New Zealand freshwater fish and two invertebrates at 15°C. The 48-h LC50 value was used as the endpoint for acute DO sensitivity as, owing to rapid mortality, this was found to best approximate the threshold lethal concentration. Median lethal time to death did not provide a reliable endpoint for comparing sensitivities. Fish LC 50 values varied from 0.54 to 2.65 mg litre -1 , with inanga whitebait (Galaxias maculatus; 2.65 ± 0.19 mg litre -1 , mean + SEM) being the most sensitive species tested. Common smelt (Retropinna retropinna; 1.83 ± 0.08 mg litre -1 ) and rainbow trout (Oncorhynchus mykiss; 1.61 ± 0.06 mg litre -1 ) were similar in their sensitivities, whereas common bully (Gobiomorphus cotidianus; 0.91 ± 0.06 mg litre -1 ) and shortfin eel elvers (Anguilla australis; 0.54 ± 0.03 mg litre -1 ) were the most tolerant fish. The shrimp (Paratya curvirostris; 0.82 ± 0.09 mg litre -1 ) and freshwater crayfish (Koura, Paranephrops planifrons; 0.77 ± 0.06 mg litre -1 ) were also tolerant to low DO.

“…Sloman et al (2008) reported that juvenile sculpins (Oligocottus maculosus) performed ASR, and this occurred at lower O 2 tensions compared with adults; and in juvenile guppies (Poecilia reticulata), ASR behaviour increased growth rate during hypoxia (Weber and Kramer, 1983). But the progression in ASR throughout early life in fish has not previously been correlated with events of respiratory development within the same species.…”

Aquatic surface respiration and swimming behaviour in adult and developing zebrafish exposed to hypoxia

Severe hypoxia elicits aquatic surface respiration (ASR) behaviour in many species of fish, where ventilation of the gills at the air-water interface improves O 2 uptake and survival. ASR is an important adaptation that may have given rise to air breathing in vertebrates. The neural substrate of this behaviour, however, is not defined. We characterized ASR in developing and adult zebrafish (Danio rerio) to ascertain a potential role for peripheral chemoreceptors in initiation or modulation of this response. Adult zebrafish exposed to acute, progressive hypoxia (P O2 from 158 to 15 mmHg) performed ASR with a threshold of 30 mmHg, and spent more time at the surface as P O2 decreased. Acclimation to hypoxia attenuated ASR responses. In larvae, ASR behaviour was observed between 5 and 21 days postfertilization with a threshold of 16 mmHg. Zebrafish decreased swimming behaviour (i.e. distance, velocity and acceleration) as P O2 was decreased, with a secondary increase in behaviour near or below threshold P O2 . In adults that underwent a 10-day intraperitoneal injection regime of 10 μg g −1 serotonin (5-HT) or 20 μg g −1 acetylcholine (ACh), an acute bout of hypoxia (15 mmHg) increased the time engaged in ASR by 5.5 and 4.9 times, respectively, compared with controls. Larvae previously immersed in 10 μmol l −1 5-HT or ACh also displayed an increased ASR response. Our results support the notion that ASR is a behavioural response that is reliant upon input from peripheral O 2 chemoreceptors. We discuss implications for the role of chemoreceptors in the evolution of air breathing.
