  1. 11. Contextual factors influencing the development of a circular business model in aquaponics : a case study of Peckas Tomater

    Master-uppsats, SLU/Dept. of Economics

    Författare :Sofia Björkén; Elin Bystedt; [2019]
    Nyckelord :aquaponic; bio-economy; business model; circular business model; circular bio-economy; circular economy; controlled environmental farming;

    Sammanfattning : Research within the area of aquaponics is mostly focusing on technical perspectives such as aquaculture, hydroponics, and engineering. There are also few existing commercial aquaponics businesses globally and little knowledge about how aquaponic business model develop in practice. LÄS MER

  3. 12. A circular production of fish and vegetables in Guatemala : An in-depth analysis of the nitrogen cycle in the Maya Chay aquaponic systems

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Erik Björn; [2018]
    Nyckelord :Aquaponics; Nitrogen balance; Nitrogen cycle; Nitrification; Denitrification; Akvaponi; kvävebalans; kvävecykel; nitrifikation; denitrifikation;

    Sammanfattning : This study was done with the aim of deepening the understanding of the Maya Chay aquaponic systems. To meet the aim, a literature study on aquaponics, with an emphasis on the nitrogen metabolism in such systems, was conducted. LÄS MER

  4. 13. Miljömässiga kundvärden i en akvaponi : En studie av alternativa kundvärden när en ekologisk certifiering inte är möjlig

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Författare :Nathanlie Nygren; [2016]
    Nyckelord :Aquaponics; sustainable development; customer value; environment; market; survey; organic; local production; certification; Akvaponi; hållbar utveckling; kundvärde; miljö; marknad; enkätundersökning; ekologisk; lokal produktion; närproducerat; närodlat; certifiering;

    Sammanfattning : I en akvaponi odlas fisk och grönsaker i ett kretslopp med cirkulerande vatten. Enligt EU:s regelverk, EG nr 889/2008, kan ett sådant odlingssätt inte certifieras ekologiskt. Problematiken uppstår i hur en giftfri odling kan nå de miljömedvetna konsumenterna utan en certifiering. LÄS MER

  5. 14. Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Lisa Sandell; [2014]
    Nyckelord :aquaculture; earthworm protein ; fish feed; recycling strategies ; vermiculture;

    Sammanfattning : Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. LÄS MER

  7. 15. Aquaculture effluents as fertilizer in hydroponic cultivation : a case study comparing nutritional and microbiological properties

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Johan Lund; [2014]
    Nyckelord :Organic hydroponic; Aquaponic; Aquaculture; Plant nutrition; Microbial horticulture;

    Sammanfattning : This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. LÄS MER
