  1. 1. Seaweed Integrated Mariculture : Prospects and Constraints Towards Increased Sustainability

    Författare :Christina Halling; Max Troell; Nils Kautsky; Marc Verdegem; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integrated aquaculture; Gracilaria chilensis; Seaweed farming; salmon farming; nutrient reduction; dissolved nutrients; Chile; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Increased global demand for seafood and stagnating catches from capture fisheries contributed to the doubling of aquaculture production taking place the last decade. Expansion within the aquaculture sector is expected to persist, and by many seen as the only mean to meet future demand for seafood. LÄS MER

  3. 2. Meanwhile, in Aysén-Patagonia : exploring discursive transformations on environment and development in a remote periphery

    Författare :Pamela Bachmann-Vargas; the Netherlands Wageningen Wageningen University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Patagonia, is an imaginary territory that comprises the south of Chile and Argentina. Historically, Patagonia has captivated an image of far-off lands and wilderness, embedded in a remote and peripheral context, which in turn has often been idealized as ‘pristine’. LÄS MER

  4. 3. Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; population genetics; aquaculture escapee; hybridisation; corkwing wrasse; lumpfish; cleaner fish translocation; sea lice; range expansion; fishery management;

    Sammanfattning : Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control in salmon aquaculture, often considered to be more environmentally friendly than other delousing methods. LÄS MER

  5. 4. Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conservation; Population structure; Genetics; Aquaculture; Hybridization; Corkwing wrasse; Cleaner fish; Sea lice; Symphodus melops; Escapee; Range expansion;

    Sammanfattning : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. LÄS MER

  7. 5. Intestinal functions in animals : an experimental study on horses, pigs, cows and fish

    Författare :Eje Collinder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Animals and humans live in symbiosis with an active gastrointestinal ecosystem. The balance of the system is maintained by the main actors, the macroorganism, the microflora and the environment, in concert. LÄS MER
