RAS Talk Podcast

The RAS industry is not for the faint of heart. The purpose of this “Lessons learned” keynote is to identify those challenges we are facing right now and sharing experiences of how to solve these problems. At RASTECH 2023, we wanted to talk about the mistakes and the setbacks, but always in the spirit of learning how to progress and develop from them.

Panelists:

• Damien Claire, chief sales and marketing officer at Atlantic Sapphire
• Per Heggelund, founder of AquaSeed, Sweet Spring Salmon and now, Andfjord Salmon
• Justin Henry, owner of Henry Aquaculture Consult and aquaculture business director at University of British Columbia
• Sylvia Wulf, president and chief executive of AquaBounty Technologies

Rodrigo Mezerhane is the senior project manager at Blue Star Foods in the United States and his latest project is an interesting venture into a unique species in a recirculating aquaculture system (RAS). Atlantic blue crabs are cannibalistic which makes juvenile survival rates in captivity very low. This project’s solution is to capture Atlantic blue crabs from local fishermen and raise the stock through its late molting stage, instead of raising it in land from its early stages. But this doesn’t mean the species still doesn’t come with challenges. Rodrigo shares the meticulous challenge of establishing good Standard Operating Procedures (SOPs) in order for the facility to raise the blue crabs to be ready and harvested for consumers.

It truly takes a village to raise the next generation of recirculating aquaculture farmers. Kevin Hoffman is the instructor and program manager for Onalaska High School’s aquaculture program in Washington State, United States. Through his hands-on program, students learn many practical skills, including feeding, sampling, fish husbandry, construction and maintenance. In this episode, Kevin shares how he grew this program to what it is today and how others can do the same.

Last July, Kingfish Maine was forced to go head-to-head against an anti-aquaculture group that wanted to put a stop to all aquaculture development in Jonesport, Maine. The aquaculture moratorium was put to a vote and local residents rejected the proposal 201 to 91. Now that the road is clear for the company to begin construction, Dianna Fletcher, communications consultant, shares how the company earned its social license through targeted public relations strategies.

When the island country of Singapore imports more than 90 per cent of its food supply, this new RAS project hopes to be a local solution.

Vismar Aqua is a Ukrainian RAS design firm that built the largest RAS shrimp farm in Europe, Merman’s House. When Russia’s invasion forced the farm to close after only four months in operation, the company decided to donate its first batches of shrimp to the Ukrainian army. Founder and chief technology officer, Lubomir Haidamaka, sits down with co-hosts, Jean Ko Din and Brian Vinci, to share his story from his office in Kyiv, Ukraine.

Aquaponics is often described as the combination of recirculating aquaculture with hydroponics. Many favour it as the ultimate circular food production system, utilizing waste from the production of fish to be used as nutrients for the production of plants like leafy greens and tomatoes. In our world today, the aquaponics model is still appealing and is an example of the circular food systems that we’ll need for a sustainable future.

Currently, there are a few moderate to large aquaponics operations running in the U.S.: Superior Fresh in Wisconsin, Springworks Farm in Maine, and Traders Hill Farm in Florida. In this episode of RAS Talk, co-host Brian Vinci, director of the Conservation Fund’s Freshwater Institute, sat down to talk all things aquaponics with Tracy Nazzaro, principal and president for Traders Hill Farm.
