A new solution to cleaning wastewater on shrimp farms

By Jeanine Moyer

Guelph – Ontario shrimp farmers could soon be going green – with algae. New research is using algae to naturally clean recirculating saltwater on shrimp farms. Still in the early development stages, the new, highly efficient process of removing nutrients and carbon dioxide from recirculating saltwater is being tested at the University of Guelph.

“It’s not a new idea,” admits Andreas Heyland, lead project researcher and integrative biology professor at the University of Guelph. “But we’ve been able to select highly efficient algae strains, which can be grown on the recirculating water.”

In-land shrimp farming has grown in Ontario in recent years with the demand for local shrimp in closer proximity to the marketplace. As a result, farmers are looking for new ways to manage nutrient build-up in the production system; conventional methods don’t produce much revenue and saltwater can’t be easily disposed in the environment.

Thunder Bay – There’s a naturally-occurring material found in discarded shells from crab and shrimp that offers properties with promising industrial uses.

Now, a researcher at Lakehead University is studying the material, and exploring potential for a broad range of applications ranging from wastewater treatment to better pavement.

Dr. Chris Murray studies the properties of chitosan – a naturally occurring long sugar molecule that is found in nearly all invertebrates.

“Chitosan plays a role in many animals that have exoskeletons,” says Murray. “It can be really tough and it provides a lot of physical strength for organisms.” Continue reading

Meals on Mars: Life in space – and on earth – relies on plants

Guelph – Plants are hardier than people. It’s a lesson Dr. Mike Dixon has learned in his lab, where he grows plants under “weird” conditions. Someday, astronauts will apply his research to growing food crops in space, but today his findings are benefiting Earth.

Dixon is Director of the Controlled Environment Systems Research Facility at the University of Guelph. The lab is the most advanced facility of its kind in the world, housing equipment such as hypobaric chambers that allow researchers to experiment with unusual growth conditions such as reduced atmospheric pressure.

Peterborough – Local researchers have developed several strains of algae that can clean waste water as well as serve as a potential livestock superfood.

Nobletech Inc.’s Noble Purification division is currently piloting its algae-based clean water technology, and Noble Biotech has developed sustainable animal feed that is high in protein and omega fatty acids. The company is part of the Greater Peterborough Innovation Cluster.

“Our core technology for both of these applications is the algae product itself,” explains Dr. Andressa Lacerda, a recent Ph.D. graduate of Trent’s environmental and life sciences program. “We’re algae farmers, and we grow algae with different purposes.” Continue reading

Ontario Craft Brewery ramps up production with Growing Forward 2 funding

Guelph – Time is always in short supply when you run a business. It’s something Brent Davies always seems to run out of. He’s vice president and co-owner of Wellington Brewery, so finding the time to look into funding opportunities just never seems to rise to the top of his priority pile.

“When you are a small company, and trying to do everything, you just don’t have the manpower to investigate funding options,” says Brent. “But after successfully accessing three cost-sharing projects through Growing Forward 2, I would encourage other small business to find the time. It’s a well-run program and worth the effort.” Continue reading
