  2. 1. Control of bioluminescence. Operating the light switch in photophores from marine animals

    Author : Jenny Krönström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioluminescence; physiological control; nitric oxide; krill; fish;

    Abstract : Physiologically controlled photocytes, capable of producing bioluminescence, are a common feature in the ocean among animals ranging from cnidarians to fish. The aim of this thesis was to study and compare the nature of this control, in both distantly and closely related species from the groups Teleostei Crustacea, and Cnidaria. READ MORE

  4. 2. Miniaturized Techniques for Protein Analysis

    Author : Johan Sjödahl; KTH; []
    Keywords : Proteins; peptides; proteases; Antarctic krill; Euphausia superba; capillary electrophoresis; fluorosurfactants; mass spectrometry; nanoelectrospray; ESI; MALDI; chip; high-throughput; reproducibility; sensitivity; mass accuracy;

    Abstract : Proteins are a highly diversified group of molecules, andfor their study, advanced analytical tools are required. Inparticular, a need for high-throughput techniques has emergedin order to enable the characterization of large sets ofproteins. READ MORE

  5. 3. NMR metabolomics and lipid analyses in salmonid tissue : response to alternative feeds

    Author : Liane Wagner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Salmonids are fatty fish and contain high amounts of omega-3 polyunsaturated fatty acids, beneficial in human nutrition. However, the aquaculture industry has expanded greatly in recent decades, increasing demand for fishmeal (FM) and fish oil (FO) for fish feed, while the supply of fish raw materials has remained static or declined.

  6. 4. 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

  7. 5. Biodiversity and genetic patterns in marine invertebrates

    Author : Emma Vodoti; Göteborgs universitet; []
    Keywords : zoology; marine biodiversity;

    Abstract : Abstract: Systematics based on genetic data has both confirmed and contradicted earlier, morphologically defined species and their relatedness. Morphology does not always correspond to genetic lineages, and this will inevitably affect both traditional systematics as well as biodiversity assessments. READ MORE
