..., the stimulus that triggers the production of sounds in the lobster's natural habitat is not known. We investigated the influence of two fish that are known to prey on lobsters, cod ( Gadus morhua ) and striped bass ( Morone saxatilis ), on the production of sounds by American lobsters. In addition, we examined...

...L. H. Petersen; A. K. Gamperl SUMMARY Recent in vivo experiments on Atlantic cod ( Gadus morhua ) acclimated to chronic hypoxia (6-12 weeks at 10°C; P w O 2 ~8-9 kPa) revealed a considerable decrease in the pumping capacity of the heart. To examine whether this diminished cardiac performance...

...Justin J. Meager; Paolo Domenici; Alex Shingles; Anne Christine Utne-Palm SUMMARY We examined the effect of turbidity (0.5–14 beam attenuation m –1 ) and predator attack speed (150 and 296 cm s –1 ) on escape responses of juvenile cod Gadus morhua in the laboratory. We triggered escape responses...

... to different settings of aerobic capacities in populations of cod ( Gadus morhua ) along a latitudinal cline, maximum activities of key enzymes of mitochondrial metabolism and their respective mRNA levels were compared in white muscle and liver of cold (4°C) and warm (10°C) acclimated individuals from cod...

...Paul W. Webb SUMMARY The kinematics of plaice ( Pleuronectes platessa, L =22.1 cm) and cod ( Gadus morhua, L =25.0 cm, where L is total fish length)swimming at various speeds at the bottom and lifted to heights, h , of 10, 50 and 100 mm by a thin-wire grid were measured. For cod, tailbeat frequency...

...D. M. Webber; R. G. Boutilier; S. R. Kerr; M. J. Smale SUMMARY We report the results of an experiment designed to investigate the feasibility of using differential pressure to estimate the swimming speed and metabolic rate of Atlantic cod ( Gadus morhua ). Seven cod were fitted with a miniature...

...M. Berenbrink; C. R. Bridges ABSTRACT The effects of catecholamines on the pH and the cellular ion and water content were investigated in red blood cells from the Atlantic cod ( Gadus morhua ). Noradrenaline induced a rapid decrease in the extracellular pH (pHe) of red blood cells suspended in a CO...

...Lena Sundin; Stefan Nilsson ABSTRACT We have estimated the branchial venous blood flow in the Atlantic cod by direct single-crystal Doppler blood flow measurements in vivo . In the undisturbed animal, this flow amounts to 1.7 ml min −1 kg −1 , which corresponds to about 8 % of the cardiac output...

... a directional pattern of infrasound in the sea. Using a standing-wave acoustic tube, we have studied the sensitivity of cod to infrasound down to 0·1 Hz by means of the cardiac conditioning technique. The threshold values, measured as particle acceleration, showed a steady decline towards lower frequencies...
