  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. Seaweed in the tropical seascape : Importance, problems and potential

    Författare :Stina Tano; Christina Halling; Sofia Wikström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. LÄS MER

  4. 3. Anthropogenic Disturbances and Shifts in Tropical Seagrass Ecosystems

    Författare :Johan S. Eklöf; Nils Kautsky; Patrik Rönnbäck; Teresa Alcoverro; Stockholms universitet; []
    Nyckelord :Aquaculture; feedback mechanisms; Kenya; management; overgrazing; regime shift; resilience; seagrass; seaweed farming; sea urchins; Tanzania; trophic cascades; Zanzibar; NATURAL SCIENCES; NATURVETENSKAP; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : Seagrasses constitute the basis for diverse and productive ecosystems worldwide. In East Africa, they provide important ecosystem services (e.g. fisheries) but are potentially threatened by increasing resource use and lack of enforced management regulations. LÄS MER

  5. 4. Women in the Seascape : Gender, Livelihoods and Management of Coastal and Marine Resources in Zanzibar, East Africa

    Författare :Sara Fröcklin; Maricela de la Torre-Castro; Lars Lindström; Nils Kautsky; Meryl J. Williams; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gender; fisheries; invertebrate harvesting; seaweed farming; coastal and marine management; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : All over the world, coastal populations depend on, and influence, the environment in pursue of their livelihoods. Managing the environment, while meeting the growing demand for marine resources, is a challenge. It further requires knowledge about all actors. LÄS MER

  7. 5. New Perspectives in Multi-trophic Aquaculture

    Författare :Matthew Hargrave; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaculture; kelp; seaweed; IMTA; mussel; bioremediation; Saccharina latissima; Mytilus edulis; extractive aquaculture; biofouling; epiphytes;

    Sammanfattning : Aquaculture, the farming of marine and aquatic organisms, is currently the fastest growing food production sector globally. As capture fisheries have stagnated and the fishing down of marine food webs has been seen to be unsustainable, aquaculture is filling the deficit in providing food to a growing world population.
