    Extension of the Pre-rigor Period in Ischemic White Muscle from Yellow-eye Mullet Aldrichetta forsteri) and New Zealand Snapper (Pagrus auratus) as Affected by Hyperbaric Oxygen Treatment (2004)

    Notes: : Chemical anesthesia (AQUI-STM Plus) was used to harvest tank-rested yellow-eye mullet (Aldrichetta forsteri) and snapper (Pagrus auratus) in a “rested” state. Fillets were stored at half the acclimated temperature under hyperbaric, hyperoxic conditions and compared with fillets stored under normobaric, hyperoxic conditions. Postmortem (PM) changes in white muscle (WM) cut-surface pH and key metabolites (lactate, adenosine triphosphate [ATP], and inorganic phosphate [Pi]) were measured. Hyperbaric, hyperoxic storage extended the pre-rigor period in the rested WM by delaying PM changes. Prolongation of pre-rigor was greatest in rested snapper WM. This was attributed to an extended period of aerobic metabolism in PM rested WM.

    In vitro carbon dioxide excretion from erythrocytes of two species of Antarctic fishes and its inhibition by catecholamines (2000)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 57 (2000), S. 0

    Topics: Biology
    Notes: This study was designed to investigate whether the blood of Pagothenia borchgrevinki, exhibits a Haldane effect, and whether activation of a Na+/H+ antiporter increases transport of intracellular protons and Bohr protons out of the erythrocytes resulting in inhibition of CO2 excretion in both P. borchgrevinki, and Dissostichus mawsoni. When carbon dioxide dissociation curves were determined from blood samples pooled from three fish under oxygenated and deoxygenated conditions a Haldane effect was observed. Using an in vitro, CO2 excretion assay, the rate of HCO3− dehydration was determined on blood and plasma equilibrated under an N2atmosphere then rapidly oxygenated with air in the presence of 10−5 M noradrenaline or acetazolamide (1004M). Whole blood and plasma from P. borchgrevinki, and D. mawsoni, were equilibrated with 0·5% CO2 in air and assayed in the presence of 10−5 M noradrenaline. Erythrocyte CO2 excretion rates were depressed significantly by noradrenaline in both species. The whole blood HCO3− dehydration rate was depressed significantly following rapid oxygenation in the presence of acetazolamide indicating that the pathway of CO2 excretion included activation of intracellular carbonic anhydrase and an adrenergic receptor.

    Plasma cortisol and osmoregulatory changes in sockeye salmon transferred to sea water: Comparison between successful and unsuccessful adaptation (1992)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 41 (1992), S. 0

    ISSN: 1095-8649

    Topics: Biology
    Notes: Gill Na+-K+-ATPase activities, haematocrits, condition factors, plasma osmolarities, cortisol, chloride and sodium concentrations were measured in sockeye salmon (Oncorhynchus nerka) transferred rapidly from fresh water to sea water. Comparisons were made between salmon that successfully adapted to sea water and salmon that failed to adapt. In salmon that successfully adapted to sea water there was a brief but large fluctuation in cortisol, and plasma ionic concentrations rose initially but were regulated after 24–48 h. In salmon that failed to adapt to sea water, cortisol remained elevated, haematocrit increased, plasma ionic concentrations were not regulated and the salmon became severely dehydrated and eventually died. The results are discussed with respect to physiological stress and seawater adaptation.
