För och nackdelar med recirkulerande akvakultursystem - Metodens framtid i Sverige
(2019) MVEK02 20191Studies in Environmental Science
- Abstract
- Until year 2050 the world population will be increased with more than two billion people, this will lead to high demands of food supply. At the same time many of the worlds fish stocks are overfished or under a lot of pressure due to the environment. This study has investigated the pros and cons with recirculating aquacultursystems from the viewpoint’s energy use, carbon dioxide emissions and ethical aspects in comparation with other aquaculture methods in addition to see if recirculating aquaculture systems have a future in Sweden. The methods used are a literature study with a complemented interview. This study shows both a high energy use and high carbon dioxide emissions for recycling aquacultursystems compared to other methods but... (More)

Finally, this study shows that recycling aquacultursystems can be a future solution to issues like food shortage, eutrophication, greenhouse gas emissions and overfished fish stocks. (Less)
