On Friday 6th June 2025, the Faculty of Fisheries and Protection of Waters of the University of Souht Bohemia in České Budějovice (FFPW USB) welcomed experts from the Federal Agency for Water Management In Austrian. The visit took place as part of the international AquaCycle project (INTERREG VI-A Austria – Czech Republic 2021–2027), which focuses on sustainable water and nutrient management in modern aquaculture systems.
The programme took place at the Experimental Fish Culture Facility, where participants attended a series of lectures delivered by experts in the field and went on a guided tour of the facility. The introductory part focused on recirculating aquaculture systems (RAS), a key technology for environmentally friendly fish production.
Particular attention was given to the presentation of a hybrid model connecting RAS with a traditional pond. This innovative approach enables the more efficient use of nutrients, reduces the ecological burden, and supports the integrated production of other aquatic organisms at the same time.
Another interesting topic was the use of edible insects, specifically black soldier fly larvea (Hermetia illucens and mealworm (Tenebrio molitor), as a sustainable source of protein for aquaculture feed. The lectures covered the technology of breeding these insects, the relevant legislation, and how they can be included in closed production cycles.
The meeting provided a valuable opportunity for Czech and Austrian experts to share their experiences. Discussions covered not only technologies and biology, but also the challenges posed by climate change, energy efficiency, and the principles of the circular economy.
The FFPW USB thus once again confirmed its position as a centre of excellence in the research and development of sustainable aquaculture systems. International cooperation within projects such as AquaCycle helps connect scientific institutions across Europe and find innovative solutions for the future.
This activity was also made possible thanks to the financial support of ČSOB, Plc., which has long supported research focused on the sustainability of fisheries and the protection of nature, landscapes, and aquatic ecosystems in cooperation with the FFPW USB.
