  2. 21. Searching for sustainable aquaculture governance : A focus on ambitions and experience

    Author : Ola Luthman; Rickard Lalander; Fred Saunders; Max Troell; Megan Bailey; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aquaculture; policy; environmental governance; Social-Ecological Systems; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Aquaculture is one of the most diverse food-producing industries and is suggested as a key solution to a growing global food demand. It has been argued that aquaculture has the potential to expand sustainably in most parts of the world, especially in the EU where consumption far out weighs production. READ MORE

  4. 22. Metabolomics as a tool to evaluate salmonid response to alternative feed ingredients

    Author : Ken Cheng; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Aquaculture has largely expanded in the last decades to satisfy the growing market demands for fish products. Fishmeal and fish oil, which are traditionally used in salmonid feeds, are becoming unsustainable. Development of aquafeeds based on alternative ingredients are needed to overcome the ecological challenges. READ MORE

  5. 23. Seals and fisheries: a study of the conflict and some possible solutions

    Author : Sara Königson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; seals and fisheries; grey seal; coastal fisheries; harbour seal; seal-safe fishing gear;

    Abstract : Interaction between seals and fisheries along the Swedish coast has serious environmental and economic consequences. This thesis describes the conflict as it affects four different small-scale coastal fisheries; the eel fisheries on the west coast, the herring fisheries and salmon fisheries in the northern Baltic and the cod fisheries in the central Baltic.

  6. 24. Fish predation by the great cormorant (Phalacrocorax carbo sinensis) : analytical basis for ecosystem approaches

    Author : Maria Ovegård; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis concerns the diet of a piscivorus top predator, the Great Cormorant (Phalacrocorax carbo sinensis), in the Baltic Sea. The Great Cormorant has increased exponentially in numbers during the last decades. This has resulted in a human-cormorant conflict because of its perceived competition with fisheries and negative impact on ecosystems. READ MORE

  7. 25. Intraspecific divergence and phenotypic plasticity in behavioural profiles of teleost fish

    Author : Johanna Axling; Svante Winberg; Johan Höjesjö; Uppsala universitet; []

    Abstract : Behavioural differences between and within individuals can greatly affect the outcome of behavioural studies. In addition, behavioural interactions between individuals can compromise the health and welfare of captive fish. READ MORE
