1. 1. Novel Scale Chemistry of Salmo Salar L. : New Linkage of Otolith and Scale Chemistry to M74 Reproductive Disorder

   Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

   Författare :Michelle Von Ehr; [2022]
   Nyckelord :Thiamine; M74; Salmon; Otolith chemistry; Scale chemistry; laser-ablation coupled inductively plasma mass spectrometry;

   Sammanfattning : Baltic salmon suffer from maternally transmitted M74 reproductive disorder, which causes yolk-sac fry mortality due to thiamine deficiency. This study investigates trace elemental analyses of Baltic salmon applied on otoliths and scales and their possible link to identifying M74. LÄS MER

3. 2. Assessing the importance of freshwater tributary systems for the recruitment of Eurasian Perch (Perca fluviatilis) in Baltic Sea Coastal Ecosystems

   Master-uppsats, SLU/Dept. Of Aquatic Resources

   Författare :Joe Wastie; [2014]
   Nyckelord :Perch; Freshwater systems; Coastal areas; Coastal ecosystems;

   Sammanfattning : Populations of one of the most important predatory fish species within Baltic Sea coastal ecosystems, the Eurasian Perch (Perca fluviatilis), have declined in some coastal areas during recent decades. This has caused negative effects on an ecological, commercial, and cultural scale, and protection and restoration of recruitment areas (perch spawning grounds) are believed to be an important player in supporting future stocks.
