    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epithelial barrier function; smoltification; cortisol; osmoregulation; Aeromonas salmonicida; Atlantic salmon; rainbow trout; bacterial translocation; intestine; Ussing chamber; vegetable lipids;

    Sammanfattning : The salmonid intestinal epithelium is important for growth and health of the fish. The epithelium is exposed to a multitude of internal and external factors that can influence its function. LÄS MER

  3. 17. Alternative feed sources : Effect on gut microbiota, immunity and health of rainbow trout

    Författare :Aprajita Aprajita; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Shifting from conventional fishmeal- and soymeal-based aquafeed to low-cost, sustainable dietary alternatives is essential for expansion and resilience in aquaculture. Possible alternative feed resources include under-utilised organic wastes from agriculture and households and by-products from forestry. LÄS MER

  4. 18. Effects of feeding yeasts on blood physiology and gut microbiota of rainbow trout

    Författare :David Huyben; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Yeast represents a sustainable protein alternative to fishmeal in diets for farmed fish, although more than 40% replacement has been shown to reduce fish growth and welfare. This thesis investigated the effects of feeding high inclusions of inactivated and live yeasts to fish in order to replace fishmeal without negative health consequences. LÄS MER

  7. 20. 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
