... immediately without staining. Wild Atlantic cod, Gadus morhua Linnaeus 1758, with a total length of 46.4±0.45 cm (here and elsewhere: mean±s.e.m.; N =106 animals) were caught by hook and line on board commercial fishing boats in the Mersey Estuary adjoining the Irish Sea near Liverpool, UK (53°25′ N...

... 2015 23 2 2016 © 2016. Published by The Company of Biologists Ltd 2016 Summary: Glucose utilized by fish hearts is converted exclusively to lactate and not used to support aerobic metabolism. ATP produced in the cytosol may be a requirement for ionic regulation. Gadus morhua...

..., swimming efficiency and survival. We report on free-swimming wild Atlantic cod ( Gadus morhua ) held in a large mesocosm that exhibited distinctly aberrant rotational swimming (scouring) when externally tagged with accelerometer data loggers. To quantify the phenomenon, the cod were tagged with two sizes...

...William R. Driedzic; Kathy A. Clow; Connie E. Short SUMMARY The aim of the present study was to assess whether mechanisms of glucose trafficking by red blood cells (RBCs) relate to species-specific extracellular glucose levels. Atlantic cod ( Gadus morhua ), Atlantic salmon ( Salmo salar ), cunner...

... (i.v.) and intramuscularly (i.m.) injected pDNA in Atlantic cod ( Gadus morhua L.). The anatomical distribution of pDNA was determined using both morphological and radiotracing methods. Cellular uptake and receptor specificity were studied in cultures of cod atrial endocardial endothelial cells (aEEC...

...Jennifer R. Hall; Connie E. Short; William R. Driedzic SUMMARY cDNAs of putative glucose transporters, GLUT4 and GLUT2, were cloned from Atlantic cod ( Gadus morhua ). The GLUT4 cDNA encodes a 503 amino acid and the GLUT2 cDNA a 506 amino acid protein. Phylogenetic analysis, amino acid sequence...

...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...

...Jennifer R. Hall; Tyson J. MacCormack; Catherine A. Barry; William R. Driedzic SUMMARY A putative glucose transporter, GLUT1, is reported for Atlantic cod Gadus morhua . A combination of RT-PCR, RLM-RACE and genome walking were used to articulate a 4560 bp cDNA (GenBank accession number AY526497...

...Kathy A. Clow; Kenneth J. Rodnick; Tyson J. MacCormack; William R. Driedzic SUMMARY This study investigated the regulation of glucose uptake in Atlantic cod( Gadus morhua ) hearts. Isolated hearts were perfused with or without glucose in the medium, under either normoxic or severely hypoxic...

...Maxim Zakhartsev; Torild Johansen; Hans O. Pörtner; Ronny Blust SUMMARY The aim of this study was to determine the effects of seasonal temperature variation on the functional properties of lactate dehydrogenase (LDH) from white muscle and liver of Norwegian coastal cod ( Gadus morhua...

...Thomas E. Hall; Nicholas J. Cole; Ian A. Johnston SUMMARY Seven cDNA clones coding for different muscle-specific proteins (MSPs) were isolated from the fast muscle tissue of Atlantic cod Gadus morhua L. In situ hybridization using cRNA probes was used to characterize the temporal and spatial...

...P. V. Skov; J. F. Steffensen SUMMARY The volume of the primary (PCS) and secondary (SCS) circulatory system in the Atlantic cod Gadus morhua was determined using a modified dye dilution technique. Cod ( N =10) were chronically cannulated in the second afferent branchial artery with PE-50 tubing...

...M. Martínez; H. Guderley; J.-D. Dutil; P. D. Winger; P. He; S. J. Walsh SUMMARY This study evaluated the link between swimming endurance and condition of Atlantic cod Gadus morhua that had been fed or starved during the 16 weeks preceding the tests, and assessed whether muscle metabolic capacities...

...Maria Faldborg Petersen; John Fleng Steffensen SUMMARY Atlantic cod Gadus morhua has polymorphic haemoglobin, which can be separated into two homozygous types, HbI-1 and HbI-2, and one heterozygous type HbI-1/2. The geographical distribution of Atlantic cod with the different haemoglobin types...

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...
