RAS engineering and design specialist Marc Sorensen takes us through the history and evolution of RAS in aquaculture. Co-host Brian Vinci also provides his insights on the beginnings of RAS technology. In this episode, we get into the technical details of the why, the how, as well as the current and emerging challenges involved in designing and operating a recirculating aquaculture system.

Guest: Marc Sorensen, president, Sorensen Engineering Ltd.

It started out as a small RAS operation in his home basement, today founder Eric Pedersen’s Ideal Fish is successfully producing Branzino for the U.S. domestic market. We talk to Pedersen and Ideal Fish’s sales and marketing director James MacKnight about the company’s journey, its innovative strategies to reach the market, and its quest to educate the consumers about RAS-grown fish.

Women account for 70 percent of the world’s seafood workers. However, many of them work in entry level, low-paying jobs and very few are in leadership roles. Is the industry paying enough attention to diversity in the aquaculture industry? Is gender diversity playing a factor into the design of RAS facilities? What resources exist for women in aquaculture for skills development and training that will allow them to move into leadership roles? These questions and more are discussed in this episode of RAS Talk.

Guest co-host: Anna DiCocco, fish culture technician, Freshwater Institute

Guests: Astrid Buran Holan, head of innovation, land-based, ScaleAQ; and Christi Dimon, farm operator, Bluehouse Miami, Atlantic Sapphire

The aquaculture industry continues to face challenges brought on by the Covid-19 pandemic. From social distancing protocols to mandatory work-from-home policies, how are RAS producers managing the day-to-day farm operations in this new norm? This episode is a discussion on Covid-19 and the impact it’s having on RAS operations, with hosts Mari-Len De Guzman and Brian Vinci, and guests from New York-based Hudson Valley Fish Farms: John Ng, CEO, and Brittany Peachey, aquaculture operations manager.

As RAS operations across the world ramp up, it is increasingly important to effectively address off-flavour issues in RAS-grown fish. The research is available for effective mitigation measures and many RAS producers are successfully implementing these recommendations. Justin Henry, director of aquaculture at Habitat Life, and John Davidson, research scientist at the Freshwater Institute, discuss some best practices in mitigating off-flavours.

Guests:

Podcasting from Honolulu, Hawaii, host Mari-Len De Guzman attended the Aquaculture America conference where she caught up with Kimberley Player, director of research at Portland, Oregon-based Equilibrium Capital. The company manages sustainability-driven real asset investment strategies and products for institutional investors. The potential of RAS for sustainability and financial gains is making it an appealing proposition for investors. Mari-Len chatted with Kimberley about the opportunities and challenges for investments within the RAS value chain. If your RAS project is ready to scale, this podcast episode is worth a listen.

Do you have what it takes to work in a RAS operation? This episode of RAS Talk tackles the current challenges as well as strategies for hiring the right people. Hosts Mari-Len De Guzman and Brian Vinci talk with Cristina Espejo, head of HR and ESAP (environmental and social action plan) at Atlantic Sapphire in Miami, Florida, and Kirk Havercroft, CEO of Sustainable Blue in Nova Scotia, Canada. These two companies are not just investing in the technology, but more importantly, they are investing in their people to develop a highly-skilled and competent RAS workforce.

All eyes are on Maine as an emerging destination for RAS development projects. In this episode, co-hosts Mari-Len De Guzman, editor of RAStech, and Brian Vinci, director, The Conservation Fund Freshwater Institute, explores the issues and developments at one of Maine’s RAS pioneers – Nordic Aquafarms. Guest Erik Heim, president of Nordic Aquafarms, takes us through the strategies and factors that led his company to choose Maine as the site for its proposed US$500-million Atlantic salmon RAS farm, as well as the challenges and lessons learned through the process.

The annual Aquaculture Innovation Workshop (AIW) is dedicated to the presentation of the latest developments in sustainable aquaculture. AIW participants come to discuss sustainable aquaculture seafood production and work to elevate an industry they feel passionately helps improve public health, protects the ocean and natural resources, and is economically viable. Leading representatives from all parts of the aquaculture seafood value chain attend the AIW, including investors, feed suppliers, producers, processors, retailers, chefs, and consumers.

WHEN IS THE NEXT AIW?

We anticipate scheduling the next AIW to take place in the late 2022 or early 2023. However, due to the uncertainty associated with the COVID-19 global pandemic, we feel it would be premature to move forward with the planning at this time.  As soon as we have details for the new dates we will be in contact with you. We thank you for your understanding. If you have additional questions, please reach out to us directly by contacting our AIW coordinator, Kata Sharrer at ksharrer@conservationfund.org.

This four-day course on water recirculating aquaculture systems started in 1995 at Cornell University in cooperation with Freshwater Institute staff. The course was held at Cornell University until 1999, after which it was held at the Freshwater Institute as a combined Cornell University/Freshwater Institute course. Course participants were initially university extension associates, however current participants include representatives from commercial fish farms, government fish hatcheries, tribal fish hatcheries, government regulators, universities, research organizations, legislative offices, and fish and wildlife organizations. The combined course continued through 2006, after which the course was taught independently by both institutions until Cornell University stopped offering a classroom course. Current course content covers the fundamentals of water recirculating systems for fish culture including mass balances to maintain water quality, unit process design, and system operation. Course topics include the following:

• RAS Overview
• RAS Water Quality
• Mass Balances
• Pumping and Piping
• Circular Tank Design
• Solids Control & Management
• Oxygenation
• Carbon Dioxide control
• Biofiltration
• Ozone & UV Processes
• Fish Health & Biosecurity
• Monitoring RAS Water Quality
• RAS Management & Operations
• RAS Design Examples
  
  

Course materials provided to participants include a binder of all presentations and a copy of the book Recirculating Aquaculture. The course includes a tour of a RAS facility for hands-on explanation of the engineering and operation. Custom variations of the four-day course (e.g., two-day versions) are available upon request.
