1. 1. MODELLING THE SMOLT PRODUCTIVITY OF BROWN TROUT (SALMO TRUTTA) IN HAGA Å

   University essay from Göteborgs universitet / Instiutionen för biologi och miljövetenskap

   Author : Lukas Almgren; [2023-10-30]
   Keywords : Brown trout; Salmo trutta; Trout habitat score; THS; Haga å; electro-fishing survey;

   Abstract : The brown trout (Salmo trutta) is a facultatively anadromous species, some individuals migrate from the rearing environment in the rivers to the sea while other individuals stay in fresh water. To determine the suitability of a stream for juvenile trout the organization SGBALANST has developed what is called the "Trout habitat score" (THS) model. READ MORE

4. 3. 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.

5. 4. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

   University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

   Author : Ola Carlström; [2023]
   Keywords : arctic char; brown trout; climate change; diet; habitat use; temperature;

   Abstract : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. READ MORE

6. 5. Effects of summer peaks on brown trout and Atlantic salmon growth and survival in hydropower-regulated Gullspång River

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Oscar Hallberg; [2023]
   Keywords : hydropeaking; hydropower; fish; salmon; salmo salar; salmo trutta; summer; survival; growth; parr; fry; korttidsreglering; vattenkraft; salmonid; salmo salar; salmo trutta; tillväxt; överlevnad; lax; öring;

   Abstract : Daily demands for electrical power are met through sub-daily release of turbined water in the form of hydropeaking. Hydropeaking’s changes to stream flow are listed as a threat to biodiversity in river ecosystems as it causes rapid habitat alteration such as increased depth and velocity, affecting the species living downstream.
