  1. 1. Development of osmo- and appetite regulation during transfer of smolt from freshwater to increasing salinities

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Jonna Hellesten; [2023-01-26]
    Keywords : ;

    Abstract : Atlantic salmon (Salmo salar) is common in Scandinavian aquaculture and must be transferred from freshwater to seawater to grow properly. Despite being assessed as ready smolts, meaning they have gone through the physiological changes to prepare for SW transfer, the transfer result in a mortality rate of around 13-19%, and significant appetite- and growth reductions.

  3. 2. Bubbles guide migrating smolts around hydropower plants

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Shona MacArthur; [2019]
    Keywords : Atlantic salmon; migration; bubble barrier; hydropower plant; predation;

    Abstract : The development of hydroelectric power production and the damming of water courses that ensues causes a threat to the migration patterns of Atlantic salmon (Salmo salar), by altering their habitat and compromising river connectivity. Because the species’ survival heavily depends on the completion of their migration between rivers and oceans, the design of guidance structures that promote successful passages around dams is a critical goal.

    Abstract : To compensate for the losses due to altered stream habitat large amounts of hatchery-reared Atlantic salmon (Salmo salar) and sea trout (Salmo trutta) are released into the Baltic Sea each year. During the last decades there have been an overall declining trend in the post-smolt survival of both hatchery reared and wild salmon in the Baltic Sea. READ MORE
