    Sammanfattning : Sandblom, Erik (2007). The venous circulation in teleost fish -Responses to exercise, temperature and hypoxia. Department of Zoology/Zoophysiology, Göteborg University, Box 463, SE-405 30 Göteborg, Sweden. In fish and other vertebrates, venous capacitance changes have important implications on venous return and cardiac filling pressure. LÄS MER

  3. 22. Safeguarding the Welfare of Fish in Aquaculture : Physiological Assessments of Stress and Welfare During Handling, Transport and Slaughter

    Författare :Per Hjelmstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The increased demand of fish for human consumption has led to a rapid expansion of aquaculture. However, there are major knowledge gaps regarding species-specific needs, which entails an increased risk that fish are exposed to various aquaculture practices that have negative effects on their welfare.

  4. 23. A Gill Filament EROD Assay : Development and Application in Environmental Monitoring

    Författare :Maria Jönsson; Ingvar Brandt; Björn Brunström; Kristian Ingebrigtsen; Håkan Olsén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; aquatic; benzo[a]pyrene; biomarker; CYP1A; environmental monitoring; EROD; fish; gill; indigo; PCB; Biologi; Biology; Biologi;

    Sammanfattning : A gill filament-based assay for the cytochrome P450 1A (CYP1A)-catalysed activity ethoxyresorufin O-deethylase (EROD) was developed in rainbow trout (Oncorhynchus mykiss) and applied to Atlantic salmon (Salmo salar), Arctic charr (Salvelinus alpinus), Atlantic cod (Gadus morhua), saithe (Pollachius virens), and spotted wolffish (Anarhichas minor). Exposure to waterborne β-naphthoflavone (βNF; 10-6 M) induced branchial EROD activity in all species but the spotted wolffish. LÄS MER

  5. 24. Effects of non-fish based raw materials on the fish muscle quality of salmonids

    Författare :Jinfeng Pan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Salmonids are considered as fatty fish and a healthy food. They are characterized by a high proportion of n-3 long chain polyunsaturated fatty acids (n-3 LCPUFA). There is great interest in producing high-quality salmonids with a reduced use of fish-based materials and a challenge to adjust feeds towards more sustainable. LÄS MER

  7. 25. From Proteomic Analysis to Biomarker Application - Studies of Carbonyl Reductase in Fish

    Författare :Eva Albertsson; Göteborgs universitet; []
    Nyckelord :Fish; Proteomics; Biomarker; Carbonyl Reductase; AhR agonists; Oxidative stress; Biomonitoring;

    Sammanfattning : Many anthropogenic substances are present in the aquatic environment, but there is limited information on how this combination of chemicals affects exposed wildlife. To assess the impact of chemicals, a biomarker approach is frequently applied in environmental biomonitoring programmes. LÄS MER
