2. 1. Migration and quality of landlocked Atlantic salmon smolt : Implications for conservation and management

   Author : Johnny R Norrgård; Eva Bergman; Larry A Greenberg; Monika Schmitz; Martyn Lucas; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; acoustic telemetry; hatchery; life history; migration mortality; regulated rivers; Salmo salar; salmon; smolt; trout; Biology; Biologi;

   Abstract : Atlantic salmon Salmo salar has a complex life cycle, including long migrations and habitat shifts for both juveniles and adults. As such, salmon populations are vulnerable to habitat degradation and fragmentation along their migratory routes. READ MORE

4. 2. Catch and effort from a recreational trolling fishery in a large lake

   Author : Anders Andersson; John Piccolo; Larry Greenberg; Ian Cowx; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Angler survey; atlantic salmon; brown trout; complemented survey; Lake Vänern; recreational fisheries; fisheries management; recall bias; Biology; Biologi;

   Abstract : Over recent decades recreational fisheries have grown substantially throughout the world. Despite this increase, catches from recreational fisheries have often been ignored in fisheries management, although this is now being remedied. READ MORE

5. 3. Atlantic salmon in regulated rivers : Migration, dam passage, and fish behavior

   Author : Daniel Nyqvist; Larry Greenberg; Theodore Castro-Santos; Olle Calles; Scott Hinch; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fish migration; fish passage; downstream migration; kelt; smolt; Biology; Biologi;

   Abstract : Hydropower dams block migration routes and disrupt longitudinal connectivity in rivers, thereby posing a threat to migratory fish species. Various fish passage solutions have been implemented to improve connectivity with varying success. READ MORE

6. 4. Forest-stream linkages : Experimental studies of foraging and growth of brown trout (Salmo trutta L)

   Author : Pär Gustafsson; Eva Bergman; Larry Greenberg; John Armstrong; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brown trout; diet; growth; riparian zone; forest-stream linkages; terrestrial invertebrates; light; primary production; Biology; Biologi; Biology; Biologi;

   Abstract : Riparian vegetation along streams and rivers affects the aquatic community in numerous ways and often operates as a link for energy flux between forest and streams. The studies presented in this licentiate thesis focus on light and terrestrial invertebrates, two factors influenced by riparian zone structure, which potentially affect stream ecosystems and thus also brown trout (Salmo trutta).

7. 5. Relations between metabolic rate, migration and behaviour in Atlantic salmon (Salmo salar) and brown trout (Salmo trutta)

   Author : Linnea Lans; Larry Greenberg; Eva Bergman; Jörgen Johnsson; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; brown trout; Standard metabolic rate; behaviour; migration; Ethology and behavioural ecology; Etologi och beteendeekologi; Biology; Biologi;

   Abstract :   ABSTRACT   Migration is common among populations of brown trout (Salmo trutta) and Atlantic salmon (Salmo salar). However, not all individuals in the same population migrate, a phenomenon referred to as partial migration. READ MORE
