Biofloc technology : a new concept to produce feed to Swedish aquaculture
The aquaculture provides many people with fish and it will increase in scale. To provide the fish with feed that is not a load on the environment the use of microbes as feed either filtrated directly from the water or recovered to become protein meal is very promising.

| description | The aquaculture provides many people with fish and it will increase in scale. To provide the fish with feed that is not a load on the environment the use of microbes as feed either filtrated directly from the water or recovered to become protein meal is very promising. Biofloc technology (BFT) is one method with filtration directly from water. It has traditionally been used in outdoor ponds that contain naturally photoautotrophic algae that provides the water with oxygen and becomes an additional food source to herbivorous and omnivorous species. BFT have shown to reduce feeding costs, maintain water quality and to help to control bacterial infections in the pond. To maintain a better water stability, BFT could be applied indoors, then sunlight becomes restrained and instead of algae, heterotrophic bacteria will dominate. The aim of this literature review was to see if this technology could have potential in Swedish aquaculture that have a colder climate. When higher water temperature can be held during all seasons, it makes it possible to grow tropical fish species. It is possible to have indoor tanks in Sweden, where fish and shrimps can grow in BFT systems. It would decrease the environmental load and an opportunity to take full responsibility for waste material and substances from the water. |

Vattenbruk bidrar idag med fisk och skaldjur till många människor och efterfrågan kommer att öka. För att kunna ge fisken föda som inte belastar miljön, behövs nya lösningar. Biofloc teknologi (BFT) är en metod som traditionellt sett varit ett system i dammar där det naturligt växer alger i vattnet. Dessa alger tillför syre och blir en näringskälla för herbivora och omnivora fiskarter. BFT har visat sig minska foderkostnader, bibehålla vattenkvalitet och har visat sig hjälpa till mot bakteriella infektioner. Syftet med denna litteraturstudie var att undersöka om denna teknik kan tillämpas i svenskt vattenbruk som har ett kallare klimat. För att bibehålla en bättre vattenstabilitet så skulle BFT kunna användas i inomhus tankar. Då kommer inte solljus ner i vattnet och istället för alger kommer heterotrofiska bakterier att dominera, det innebär att balansen i vattnet förbättras. Dessutom kan man hålla en högre vattentemperatur året runt, vilket passar för tropiska arter. Svenskt vattenbruk kan ha inomhusodling av fisk och räkor där BFT kan vara en av de tekniker som används. BFT skulle ge miljövinster och en möjlighet att kunna ta fullt ansvar för det avfallsmaterial och de ämnen som hamnar i vattnet.
