RAS Talk Podcast

We started a podcast in 2020 as a new way to engage stakeholders and extend our work on land-based recirculating aquaculture systems. The podcast is produced in partnership with Annex Business Media, the publisher of aquaculture industry publications Hatchery International, Aquaculture North America, and RAStech. Freshwater Institute director Dr. Brian Vinci co-hosts the podcast with the editor of Hatchery International and RASTECH publications. Together they tackle the important issues in land-based recirculating aquaculture systems with prominent industry leaders. Click below to listen the most recent episodes.

The RAS-produced Atlantic salmon sector has come a long way since its inception in the late 1990s, with the industry has continuously striving for success. However, it took time to get the technology there, with RAS technological components evolving greatly in the past 20-23 years. Today, we continue to improve technology and RAS facilities to produce high-quality Atlantic salmon, but must look at the biology of Atlantic salmon as well, focusing on genetic improvements to the eggs to create quality stock, as well as avoid diseases, mass mortalities, and early maturation. In this episode of RAS Talk, co-hosts Catarina Muia and Brian Vinci speak with Dr. Jónas Jónasson, Production Director at BMK Genetics & CEO at Benchmark Genetics Iceland, and Christopher Good, Director of Research at the Conservation Fund Freshwater Institute, to see how the industry is prioritizing and moving forward with the improvements of Atlantic salmon genetics.
