    The transport of freshwater fish (1975)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 7 (1975), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: A method is described for the transport of fish resulting in very few or no mortalities during or after this procedure. Commercial salt is added to the water to give a final conentration of 0–5 %, compressed air is bubbled through the water and the fish are kept in ‘salt water’ after transportation to decrease the incidence of skin infections.

    The surface area of mudfish (1976)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 8 (1976), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The surface area of two closely related mudfish species have been determined by coating the animals with masking tape. The results indicate that Labeo capensis specimens above 95 g body weight have a larger surface area than corresponding L. umbratus animals. The same is true for the fin surface area above 50 g body weight. Below these weights L. umbratus specimens have higher surface areas. The body surface area of L. capensis is always lower than that of L. umbratus in the range studied.

    Haematological assessment of generally used freshwater fish blood anticoagulants (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 17 (1980), S. 0 
    Details

    Topics: Biology
    Notes: Heparin injection B.P., containing 0·5% phenol as preservative, disodium ethylenediamine tetra-acetate (EDTA), trisodium citrate (TSC) and ammonium potassium oxalate (APO) were compared as anticoagulants for routine haematological investigations in Cyprinus carpio and Sarotherodon mossambicus. The acidic nature and haemolytic effects of EDTA and APO render them unsuitable for use with fish blood. TSC was required in higher concentrations (than heparin) for effective anticoagulation and this was undesirable for the determination of blood pH and pCO2 and certain other parameters. Several important interspecies differences in the reactions towards the anticoagulants are also reported. In general, heparin proved to be the anticoagulant of choice, although unsuitable for some assays.

    The effect of tricaine methanesulphonate (MS-222) on the microhaematocrit of fish blood (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 10 (1977), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The effects of the anaesthetic, MS-222, on the microhaematocrit value of freshwater fish have been examined. Blood containing MS-222 showed a higher haematocrit value than blood without the anaesthetic and haemolysis occurred in the former after a variable time depending on the concentration. The results are discussed in relation to previous findings.

    A seasonal study of the haematology of wild freshwater fish (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 13 (1978), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Various haematological values of wild yellowfish (Barbus holubi), carp (Cyprinus carpio) and two species of mudfish (Labeo umbratus and Labeo capensis) were examined on a seasonal basis from May 1975-April 1976, obtained from three different localities. Haematological values of fish of different length groups (from all four species) were studied at one locality during winter only. (June 1976-August 1976). Seasonal variations were observed in all of the parameters studied but no sexual differences were found and no significant changes in the haematology could be related to breeding season. Wide individual variations were evident in fish of different length groups and no correlation existed between fish length (and mass) and haematological values.

    The physiological responses of blood during thermal adaptation in three freshwater fish species (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 19 (1981), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Sarotherodon mossambicus, Cyprinus carpio and Salmo gairdneri were acclimatized at temperatures of 15, 20 and 25° C in order to study physiological responses of blood to temperature fluctuations in the laboratory. Cyprinus carpio exhibited the greater ability to survive at these temperatures. Sarotherodon mossambicus experienced osmoregulatory collapse at 15° C which also occurred in trout at 25° C. This was associated with acid-base malfunction in the trout.

    Observations on the blood of the Chinese silver carp Hypophthalmichthys molitrix (Valenciennes) (1981)
    Oxford, UK : Blackwell Publishing Ltd

    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The ranges and mean values for several blood parameters of adult specimens of Hypophthalmichthys molitrix were determined in order to establish a standard haematological profile for future investigations. Several significant correlations were established, the most important being between haematocrit, haemoglobin and erythrocyte counts. The data are discussed in relation to the general biology of this species.

    Haematological assessment of the effects of the anaesthetic MS 222 in natural and neutralized form in three fresh water fish species: haemoglobin electrophoresis, ATP levels and corpuscular fragility curves (1979)

    Topics: Biology
    Notes: The effects of MS 222 and neutralized MS 222 anaesthesia on haemoglobin electrophoresis, erythrocyte adenosine triphosphate (ATP) levels and corpuscular fragility curves were studied in Cyprinus carpio, Sarotherodon mossambicus and Salmo gairdneri. Haemoglobin electrophoresis showed no significant intra-species differences in the percentage composition of the various fractions for any concentration of MS 222 and neutralized MS 222 used. Significant interspecies differences were, however, still observed. ATP levels showed intra and interspecies differences ascribed to the response of the fish species to MS 222-induced stress and not to actual changes in erythrocyte ATP concentrations. Differences were also observed in corpuscular fragility curves for all three species when using MS 222 or neutralized MS 222 compared to curves obtained without the use of the anaesthetic, but the mechanisms involved are not clear.

    Haematological assessment of the effects of the anaesthetic MS 222 in natural and neutralized form in three freshwater fish species: interspecies differences (1979)

    Notes: Interspecies haematological differences to MS 222 and neutralized MS 222 anaesthesia were investigated in Sarotherodon mossambicus, Cyprinus carpio and Salmo gairdneri acclimated under identical laboratory conditions. Anaesthesia with MS 222 resulted in a ‘chemical stress’ in all fish, as was evident from changes in the haematological profiles of the animals. Such species specific variations in the haematology persisted throughout the whole experiment protocol which employed different concentrations of the anaesthetic. The use of neutralized MS 222, whereby aquarium water quality remained unchanged, improved the haematological profile. Possible reasons for the interspecies differences observed are discussed.

    Haematological assessment of the effects of the anaesthetic MS 222 in natural and neutralized form in three freshwater fish species: intraspecies differences (1979)

    Notes: The effects of different concentrations of natural MS 222 and neutralized MS 222 were studied on the haematology of Cyprinus carpio, Sarotherodon mossambicus and Salmo gairdneri. As judged from the results, MS 222, which is acidic in nature, produced haemo-concentration effects in all species studied, being least in the trout followed by carp and Sarotherodon mossambicus. These differences are ascribed to acid-base regulatory functions and metabolic activities of the fish species investigated. The use of neutralized MS 222 improved the haematological profiles markedly and resulted in stabilization of acid-base parameters and red blood cells sizes and numbers. Haemoconcentration effects, however, still persisted. Trout were found to be more susceptible to the stress of MS 222 anaesthesia than carp and Sarotherodon mossambicus.
