  1. 6. 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.

  4. 8. A circular economy approach for sustainable feed in Swedish aquaculture: A nutrition and physiology perspective

    Författare :James Hinchcliffe; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaculture; sustainability;

    Sammanfattning : One major challenge in aquaculture is the issue of fishmeal replacement as a protein source in aquafeeds. It is agreed that the rate of demand has now outpaced the rate of supply due to the rapid expansion of aquaculture. LÄS MER
