Players in the recirculating aquaculture system (RAS) industry will discuss key issues on post-smolt, sustainability, and animal health and welfare during the upcoming 2022 Patagonic RAS conference in Chile this month.

The conference, which opened on Nov. 17, is being promoted by BioMar. The global maker of sustainable animal feed holds the conference every two year. This month’s Patagonic RAS is the fourth version of the conference.

Apart from BioMar, other supporters of Patagonic RAS are DSMHendrix GeneticsAker BioMarineAkva GroupSalmonChile and Keepex, with, Salmonexpert as media partner.


The post-smolt block of the conference will present the experience of a case of post-smolt production in Chile. It will provide an update on topics such as the effects of light intensity and temperature on the early maturity of Salmo salar; the importance of bioreactor management; water velocity as a fundamental factor in growth, health and welfare; and other fundamental considerations in the robustness and smoltification of Atlantic Salmon.

The sustainability portion has a specific forum at the meeting. Attendees find out why recirculation systems are important for the ASC aquaculture standard; the business opportunities that may exist for applied science, based on sustainability; and the difficult path towards the reduction of water use for land-based production of salmon in the post-smolt stage within a context of green change.

Presentations during with animal health and welfare segment will discuss ways of improving productive performance in Atlantic salmon post-smolts through zinc supplementation; a review of the present and future of salmon genetics; challenges and possibilities of microbiota in RAS; recirculation aquaculture and post-smolt health; sustainability aspects taken to production figures; and improving fish health, welfare and performance through optimal vitamin nutrition.

BioMar Chile is one of the main suppliers of high-performance feed for the salmon industry in Chile. The company has more than three decades of experience in the manufacture, research and development of aquaculture feed for RAS farming strategies.
