  1. 6. Fungal and mussel protein sources in fish feed : nutritional and physiological aspects

    Författare :Aleksandar Vidakovic; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Fungal and mussel protein sources in the diet of Eurasian perch (Perca fluviatilis), Arctic charr (Salvelinus alpinus) and rainbow trout (Oncorhynchus mykiss) and their effect on growth performance, nutrient utilisation, intestinal barrier function and post-prandial profiles of plasma amino acids and whole blood parameters were evaluated in this thesis. Apparent digestibility of dry matter, sum of amino acids and gross energy in experiment with Arctic charr decreased with dietary inclusion of intact Saccharomyces cerevisiae. LÄS MER

  3. 7. Zygomycetes and cellulose residuals : hydrolysis, cultivation and applications

    Författare :Patrik Lennartsson; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; zygomycetes; fungi; lignocelluloses; ethanol; fish feed; animal feed; dimorphism; airlift; pretreatment; Biotechnology; Resursåtervinning; Resource Recovery;

    Sammanfattning : Zygomycetes is a class of fungi living worldwide as saprobes, as part of mycorrhizae, and as parasites. Humans have used some zygomycetes for centuries in the production of traditional foods, e.g. Indonesian tempe. LÄS MER

  4. 8. 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

  5. 9. Effects of replacing fish oil with vegetable oils in feed for rainbow trout (Oncorhynchus mykiss) and Arctic charr (Salvelinus alpinus)

    Författare :Andreas Pettersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : As global capture of fish has stagnated and fish consumption is increasing due to a growing human population, the demand can only be met by increased aquaculture production. Fish oil (FO), derived exclusively from wild pelagic fish, has traditionally been used as the primary lipid source in fish feeds. LÄS MER

  7. 10. Evaluation of locally available feed resources for striped catfish (Pangasianodon hypophthalmus)

    Författare :Chau Thi Da; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : This thesis investigated and compared inputs and outputs, economic factors and current feed use in small-scale farming systems producing striped catfish (Pangasianodon hypophthalmus) in the Mekong Delta. The nutrient content of locally available natural feed resources for striped catfish was determined and growth performance, feed utilisation and body indices were analysed in pond-cultured striped catfish fed diets where fish meal protein was replaced with protein from local feed resources.
