  1. 1. Large-scale releases of native species : the mallard as a predictive model system

    Författare :Pär Söderquist; Högskolan Kristianstad; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Anas platyrhynchos; Farmed; Hunting; Introgression; Longevity; Mallard; Migration; Morphology; Population genetic; Restocking; SNPs; Sweden;

    Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The production of farmed Arctic charr (Salvelinus alpinus) has increased rapidly over the last decade, and the industry is predicted to continue to grow in the coming years. One major bottleneck for this future expansion concerns the supply of viable eggs and juveniles. LÄS MER

  5. 5. Chronic stress and intestinal barrier function: Implications for infection and inflammation in intensive salmon aquaculture

    Författare :Henrik Sundh; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Intestinal barrier function; stress; cortisol; Ussing chamber; welfare; health; inflammation; neutrophils; cytokines; chronic stress;

    Sammanfattning : Aquaculture is a fast growing food-producing sector worldwide. This has increased the awareness among the public as well as governments of the need to secure the welfare and health of farmed fish. Atlantic salmon is, in non-Asian countries, one of the most successful aquacultured species. LÄS MER
