  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. Regulation of Leptin by Sexual Maturation and Energy Status in Male Atlantic Salmon (Salmo salar L.) Parr

    Author : Susanne Trombley; Monika Schmitz; Sylvie Dufour; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Leptin; leptin receptor; Atlantic salmon; Salmo salar; sexual maturation; puberty; energy balance; hepatocytes; sex steriods; Biology with specialization in Comparative Physiology; Biologi med inriktning mot jämförande fysiologi;

    Abstract : Leptin is a peripheral adiposity signal and a key hormone in energy balance regulation in mammals, acting as a link between nutritional status and the endocrine reproductive axis. If this is also the role of leptin in fish is not fully understood. READ MORE
