    The histochemistry of muscle in juvenile Atlantic salmon, Salmo solar L. (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 37 (1990), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: In fry, 1- and 2-year old juvenile Atlantic salmon, relatively small superficial red muscle fibres staining well for glycogen and succinic dehydrogenase (SDH) but with little myofibrillar ATPase, were evident on either side of the lateral line, in June. Well differentiated relatively large white fibres contained lower concentrations of glycogen than the red fibres, higher ATPase and no SDH, except traces in the larger 1- and 2-year-olds. Intermediate size pink fibres, which were also intermediate between red and white fibres in their staining properties, occurred in a thin diffuse layer along the red-white boundary, thickest at the apex near the vertebral column, and most evident in the younger fish.

    Effects of pre- and post-prandial starvation on meal size and evacuation rate of juvenile Atlantic salmon, Salmo salar L. (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 25 (1984), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: After a pre-prandial period of starvation or feeding with unlabelled food, 0+ salmon parr (0.8–11.7 g) were fed a test meal of iron particle labelled food and subsequently were again either starved or fed unlabelled food. The quantity of labelled food consumed and the evacuation rate was determined by serial radiographs. In fish of all sizes, pre-prandial starvation causes a larger test meal (as a percentage of body weight) to be consumed when compared to pre-prandially fed fish. In addition, pre-prandial starvation results in relatively larger meals as a percentage of body weight being taken by smaller compared to larger fish. This result was not evident for pre-prandially fed fish. Evacuation rate was unrelated to body size irrespective of feeding history. Post-prandial starvation decreased evacuation rate but this effect was inversely related to the quantity of food consumed. Larger meals were not evacuated differently from smaller meals if feeding occurred post-prandially, irrespective of pre-prandial starvation.

    Development and validation of methods for measuring multiple biochemical indices of condition in juvenile fishes (2003)
    Oxford, UK : Blackwell Science Ltd
    Journal of fish biology 63 (2003), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The investigation established and validated methods to measure multiple biochemical indices of condition (whole body total lipids, whole body triglycerides, muscle RNA : DNA ratio and muscle protein) simultaneously in the same individual juvenile fish. It also provided examples of their application using a species comparison (salmonids and cyprinids) of the degree of change in these indices after food deprivation. The results showed that juvenile rainbow trout Oncorhynchus mykiss were much more susceptible to a decline in all biochemical indices of condition than juvenile fathead minnows Pimephales promelas upon food deprivation. The combination of these techniques can be used to accurately assess condition and growth potential of individuals from wild fish populations.

    Hyperplasia and hypertrophy in the growth of skeletal muscle in juvenile Atlantic salmon, Salmo salar L. (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 37 (1990), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Both red and white muscle fibre numbers in juvenile Atlantic salmon increased gradually with fish length throughout the freshwater growth period. Mean fibre area increased as fish grew to 6.5 cm f.l., but thereafter was unrelated to fish length. Hyperplasia was most obvious when fish were growing fastest, and was the dominant growth process in fish over 6.5 cm f.l. Hypertrophy was most important when growth was slow, as in autumn and winter.Mean white fibre area was significantly smaller in deep muscle than at medial and superficial sites. Total cross-sectional area of red, white and total trunk muscle increased with fish length. The ratio of red: white cross-sectional area increased with fish length to a plateau at about 10% after 6.5 cm f.l.

    Strain identification in Rhizobium trifolii using DNA restriction analysis, plasmid DNA profiles and intrinsic antibiotic resistances (1985)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 30 (1985), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract Indigenous strains of R. trifolii, originating from different geographical regions, were compared using total DNA restriction analysis, plasmid DNA profiles and intrinsic antibiotic resistance patterns. The results of strain relatedness using 2 of these techniques (DNA restriction and antibiotic resistance patterns) were similar, and indicated that these strains formed a heterogeneous group. A large variation in plasmid DNA profiles was observed among the R. trifolii isolates investigated, indicating heterogeneity of plasmid DNA pools. This variation occurred even in some strains that were shown to be related on the basis of their antibiotic resistance patterns. The application of these techniques to differentiate indigenous R. trifolii strains is discussed in this report.

    Notes: Summary Except for a markedly reduced anodal electrophoretic mobility, the serum albumin of the Galapagos marine iguana was physico-chemically identical to that of terrestrial iguanids. Reduction in albumin net charge may have facilitated the adaptation of this species to a semi-aquatic environment.
