  1. 1. Gill EROD Activity in Fish : A Biomarker for Waterborne Ah-receptor Agonists

    Author : Alexandra Abrahamson; Ingvar Brandt; Björn Brunström; Janneche Utne Skaare; Uppsala universitet; []
    Keywords : Biology; biomarker; fish; gill; CYP1A; EROD; environmental monitoring; induction; inhibition; PAH; PCB; produced water; Biologi;

    Abstract : Induction of the cytochrome P450(CYP)1A protein and the connected increase in 7-ethoxyresorufin O-deethylase (EROD) activity are common biomarkers in fish. Enhanced activity of this protein signals exposure to Ah-receptor agonists such as chlorinated dioxins, co-planar polychlorinated biphenyls (PCBs) and certain polycyclic aromatic hydrocarbons (PAHs).

  2. 2. Oxidation of fish lipids during gastrointestinal in vitro digestion

    Author : Karin Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TBARS; HHE; salmon; lipids; TIM; fish; HNE; in vitro digestion; gastrointestinal; aldehydes; cod liver oil; n-3 PUFA; herring; lipid oxidation; MDA;

    Abstract : Fish and many other marine organisms, contain long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), e.g. eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). EPA and DHA has shown beneficial effects in diseases related to inflammatory processes, such as cardiovascular diseases. READ MORE

  3. 3. Does fish health matter? The Utility of Biomarkers in Fish for Environmental Assessment

    Author : Niklas Hanson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biomarkers; Fish; Environmental monitoring; Ecological risk assessment; Rainbow trout; Perch;

    Abstract : Two common strategies to assess exposure to environmental toxicants are to measure chemical concentrations in the environment and to examine the presence of certain species that are known to be sensit... merive to pollution. READ MORE

  4. 4. Studies of fish responses to the antifoulant medetomidine

    Author : Anna Lennquist; Göteborgs universitet; []
    Keywords : antifouling; fish; medetomidine; ecotoxicology; biomarker;

    Abstract : ABSTRACT Growth of marine organisms, fouling, on man-made constructions submerged in the water is regarded as a major problem. For vessels, fouling increases drag and thereby fuel consumption, wherefore antifouling paints are used. Traditionally, they contain toxic compounds, and several of these have unwanted effects in the environment. READ MORE

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

    Author : Jinfeng Pan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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. READ MORE
