  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. 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.

  4. 3. Simulation and Optimization of Recirculating Aquaculture Systems

    Författare :Simon Pedersen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; dynamic modelling; optimization; biofilter; wastewater treatment; Recirculating aquaculture;

    Sammanfattning : Recirculating aquaculture -- intensive fish farming with water treatment and reuse -- has great potential as a method for sustainable food production. Benefits over traditional aquaculture include opportunities to reduce nitrogen emissions to water, control of temperature, salinity and pH, reduced environmental impact of escapes and better protection against e.

  5. 4. Kind of turquoise : Effects of seafood eco-certification and sustainable consumption

    Författare :Malin Jonell; Patrik Rönnbäck; Max Troell; Michael Tlusty; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; eco-certification; eco-labeling; seafood; aquaculture; shrimp; LCA; consumer behavior; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Aquaculture and fisheries hold promise for supplying a growing world population with healthy food produced without undermining the earth’s carrying capacity. However, just as livestock production and agriculture, seafood production can have negative environmental impacts and if a continuous or even increased supply is to be guaranteed, the pressure on affected ecosystems needs to be limited.

  7. 5. Integrated Agriculture and Aquaculture Systems (IAA) for Enhanced Food Production and Income Diversification in Tanzania

    Författare :Deogratias Mulokozi; Håkan Berg; Ian Bryceson; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Smallholder farmers; Oreochromis niloticus; Amaranthus hybridus; food production; household income diversification; water use efficiency; farm net income; Physical Geography; naturgeografi;

    Sammanfattning : Aquaculture production in Tanzania has increased in recent years, responding to an increased demand for fish, partly because of an increasing population and declining catches of wild fish. However, the current aquaculture production is still low, dominated by small scale farming systems, that are struggling with a number of challenges such as lack of improved fish breeds, feeds, technical skills and low adoption rates.
