    Environmental effects of escaped farmed fish on natural fish fauna – a case study in Lake Storsjön

    Rainbow trout has been farmed as a food fish in Sweden for several decades, and fish escaping from farms is a recurring problem. However, there is still a lack of knowledge about the consequences of fish escapes. This is now being studied in this case study in Storsjön.

    Microbiome monitoring for risk assessment in recirculating aquaculture systems

    Harmful bacteria have a negative impact in aquaculture operations, resulting in increased fish mortality and reduced yield. This project aims to understand the factors leading to their proliferation and develop a monitoring strategy together with commercial partners.
