  5. 4. Genetic and Ecological Consequences of Fish Releases : With Focus on Supportive Breeding of Brown Trout Salmo trutta and Translocation of European Eel Anguilla anguilla

    Författare :Johan Dannewitz; Jacob Höglund; Erik Petersson; Ian Fleming; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; conservation; fishery management; panmixia; genetic variation; effective population size; hatchery selection; Biologi; Biology; Biologi;

    Sammanfattning : Although the practice of releasing fish into the wild is common in the management and conservation of fish populations, the success of release programmes and the potential harmful genetic and ecological effects that may follow are rarely considered. This thesis focuses on genetic and ecological consequences of fish releases, exemplified by supportive breeding of brown trout (Salmo trutta) and translocation of European eel (Anguilla anguilla).
