Incorporating microalgae into recirculating aquaculture systems (RAS) can more effectively manage waste while transforming it into valuable products, according to researchers in Germany and Belgium.
Read MoreScientists delve into rising incidence of mycobacteriosis on Norwegian salmon farms
Cases of mycobacteriosis, a serious disease affecting Atlantic salmon predominantly related to Mycobacterium salmoniphilum infections, appear to be on the increase in Norway.
Read MoreBacterial risks in recirculating systems can be managed, study suggests
There is a risk that antibiotic resistant bacteria of the Aeromonas genus can be introduced into recirculating aquaculture systems (RAS), according to new research in France — while fish feed can provide bacteria with a route into these highly controlled production environments.
Read MoreRAS water exchange rates could affect Nile tilapia welfare
Recirculating aquaculture systems (RAS) are often viewed as viable options for culture of certain fish species in the face of growing environmental regulations for sustainable aquaculture practices. New work from researchers at the Kwame Nkrumah University of Science & Technology in Ghana suggests that moderately high levels of water exchange in RAS provide the best…
