“…Yet another possibility is that severe hypoxia may be perceived by fish as a noxious or painful stimulus. Some authors have identified an aversive behaviour that may lead fish away from regions of severe hypoxia and toward the surface (Petersen and Petersen, 1990;Weltzien et al, 1999;Poulsen et al, 2011;Cook et al, 2013). In the present study, ASR behaviour in zebrafish was punctuated with brief trips to the bottom of the chamber before returning rapidly to the surface.…”

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.

“…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.

“…When fish are put in a respirometer, it is likely that they are not at their SMR level for most of the time. When these fish are exposed to hypoxia, they will respond with an avoidance reaction (Petersen & Petersen 1990) or a reduction of external activity. In the latter case the response wdl show a conformer type response.…”

“…At a certain [02] fish often show avoidance behaviour (Gee et al 1978, Petersen & Petersen 1990, or move to the surface for different l n d s of surface breathing (Kramer & McClure 1982). If the fish do not migrate or switch to another breathing pattern, then their tolerance to hypoxia depends on 2 factors: maintenance of oxygen extraction and/or reduction of oxygen consumption.…”

Long-term hypoxia is a general phenomenon on the Italian Adriatic coastline, and is mainly caused by continuous eutrophication. The sensitivity of sole Solea solea to long-term hypoxia was investigated. Healthy S. solea obtained from trawls were kept at l g°C in aquana for at least 2 mo. The fish were exposed to hypoxia after a preacclimation penod of 30 h at normoxia Oxygen levels dunng normoxla were kept constant at 80% air saturahon (16.6 kPa, 6 . 4 mg I-' OZ); during hypoxia oxygen levels were set at 60, 40, 20, 12 or 6 % air saturation (4.8, 3.2, 1.6, 1.0, 0.5 m g I-'). During the expenment oxygen consumption was measured continuously. At the end of each experiment, blood samples were taken from anaesthetized specimens. Oxygen consumption patterns were statistically analyzed. A novel technique is described for the determination of the standard metabolic rate and the scope for activity of free-slulmmng animals. The resting metabolic rate and the scope for activity showed significant changes at reduced oxygen levels Activ~ty levels declined progressively starting at 40 % air saturation Restlng levels remained constant between 80 and 20 % air saturation, but fell below the standard metabohc rate at 12 and 6 % Blood lactate levels were increased at 12 and 6 % , indicating anaerobic metabolism. Data show that 40% air saturation should be considered as a limiting level, while the incipient lethal level lies between 12 and 20%.
