Update on Aquaponic Organic Certification in Canada

Recently, the Standards Council of Canada published a new organic standard for aquaculture to help make organic seafood more widely recognizable. However, this label presents its own set of challenges when it comes to organic certification. Most importantly, vegetables and fruits grown in aquaponic systems can be certified organic under the organic aquaculture standard, even though this would not be allowed under the Canadian Organic Standards (COS). Understandably, this has created some challenges.

Under the Safe Food for Canadians Regulations, aquaponic products can now be legally labelled as organic if they are certified by an approved certifying body in accordance with the organic aquaculture standard. According to the CFIA, producers are encouraged to provide voluntary information about which standard the product was certified under. Organic labelling is necessary if a company wishes to export its products outside of its province of production. However, since aquaponics are newly regulated, aquaponic producers will get a grace period of 24 months once the Regulations come into effect on Jan. 15, 2019, during which organic producers will not have to be certified.

10,000 Square Foot Indoor Vertical Aquaponics Farm in Calgary

Deepwater Farms in Calgary raises 900 kilograms of Australian sea bass (or barramundi) every month. The waste is broken down with micro-organisms to create nitrates that fertilize the more than a million seedlings grown less than every two weeks under LED lights in the facility. They were recently featured in this CBC video and article.

Deepwater supplies the top restaurants in Calgary with baby kale, arugula, watercress, red pac choi, mustard greens.

Only One Third Of Canada's Fish Stocks are Healthy and They Continue to Decline

Oceana Canada's 2018 Fishery Audit is available for download here.



Below is an executive summary:

Oceana Canada’s first annual Fishery Audit in 2017 revealed that our fish stocks are not delivering nearly as much as they could, for oceans or for people.

In 2017, only one-third of our stocks were considered healthy. Of the 26 critically depleted populations, only three had rebuilding plans in place. Big gaps remained in the data required to manage stocks effectively.

One year later, some progress has been made. Fisheries and Oceans Canada (DFO) has made significant investments in federal fisheries science, and the department continues to increase transparency by releasing its annual Sustainability Survey for Fisheries and departmental work plans.

However, much more work needs to be done if our seafood industry is going to reach its potential.

Recent investments in federal fisheries science capacity has not yet yielded measurable change in the reported metrics. DFO is falling behind on implementing work plans developed in response to the Auditor General’s 2016 report. For example, four of five rebuilding plans promised by March 2018 remain incomplete. Key policy instruments have not been fully implemented or remain in draft form, including the proposed Fishery Monitoring Policy. Meanwhile, scientific and management information produced by DFO is often published late or not at all.

On the water, there have been few changes in stock health. This is to be expected: it takes time for investments in science and policy to be reflected in measurable changes in the abundance of fish populations. However, the slow pace of policy implementation means the long-term decline in Canada’s fish stocks has not yet been halted, let alone reversed.

Oceana Canada has recommended specific actions — detailed here — to address issues raised in this Audit. These include completing work plans and rebuilding plans, filling data gaps and finalizing a national catch-monitoring policy.

Charlie Shultz Interview - Sustainable Controlled Environment Food Production






This is episode 23 of the Get in My Garden Podcast. Today we have another very special episode. The subject is Controlled Environment Agriculture. We meet Charlie Shultz, a researcher, farmer and teacher; a pioneer in the field of aquaponics and lead faculty in the very impressive Controlled Environment Agriculture Program at Santa Fe Community College.

Charlie began working with fish and plants as an undergraduate at Virginia Tech while double majoring in Biology and Fishery Science. His work has sent him to many locations including 14 years at the University of the Virgin Islands in St. Croix, U.S. Virgin Islands, where he researched indoor aquaponics production and its many facets from nutrition and system economics.

We will cover a lot of topics from aquaponics systems vs hydroponics, their economics, food security and water supply challenges the world faces, and how these controlled environment agriculture systems are the solution.

UN Warns of Overfishing as Per-Capita Consumption Hits All-time High

A new report from the United Nations Food and Agriculture Organization (FAO) shows that per capita fish consumption is above 20 kilograms a year for the first time. Almost a third of commercial fish stocks are now overharvested at biologically unsustainable levels. But the good news is that a growth in rapid aquaculture has helped on the supply side, but population growth and demand are still outpacing supply. This represents an opportunity for sustainable food productions systems like aquaponics.

BC Government Sets 2022 Deadline For Open-Pen Fish Farms

The B.C. government will not cancel provincial tenures for 20 coastal open-pen fish farms, instead giving the industry and its thousands of jobs a four-year reprieve while the province waits for Ottawa to take the lead on the issue.

The NDP government has been pressuring fish farms to switch to closed land-based facilities, where there’s no risk to wild salmon. But the industry has said it’s not financially feasible. The province intends to encourage more research on land-based fish farms during the four-year transition.

The Union of British Columbia Indian Chiefs (UBCIC) applauded the announcement in the following press release.

(Coast Salish Territory/Vancouver, B.C. – June 20, 2018) The UBCIC applauds today’s announcement as an initial step on the pathway to preserve and safeguard the future of wild salmon consistent with the rights, cultural practices and economic livelihoods of many First Nations throughout BC.

Today’s announcement recognizes the significant role wild salmon play in the cultures, lives and economies of First Nations peoples throughout the province. The province has begun to demonstrate its commitment to the implementation of the UN Declaration on the Rights of Indigenous Peoples by recognizing the authority of our Indigenous decision-making processes and our rights to grant or withhold our free, prior and informed consent to projects which impact our title and rights.

Chief Bob Chamberlin, Vice-President of the UBCIC, states “Open net-pen finfish aquaculture presents a very real threat to wild salmon, First Nations communities and to the economy of British Columbia. These new requirements, which necessitate industry-First Nations protocol agreements and which place the onus on salmon farmers to prove their operations present less than minimal risk to wild salmon populations, are years overdue. If wild salmon are to survive, this industry needs to move to on-land closed containment facilities.”

The UBCIC further supports the appointment of the new Wild Salmon Advisory Council, and awaits with great anticipation the Council’s final report and encourages the province to provide the necessary resources to ensure the report is enacted.

For many years the UBCIC has been mandated through resolutions to advocate for the removal of Atlantic salmon fish farms from our coast for the benefit of our wild salmon populations. In September of 2018, the UBCIC in partnership with the BCAFN will be hosting the 2018 Wild Salmon Summit to develop a First Nations designed province-wide strategy to safeguard this important species for future generations.

Organic Aquaculture Guidelines for Canada

The Canadian General Standards Board has published a guide for organic aquaculture production.

Organic production is a holistic system designed to optimize the productivity and fitness of diverse communities within the ecosystem, including soil, sediment and benthic organisms; crops; livestock and people. The principal goal of organic production is to develop operations that are sustainable and harmonious with the environment.

This standard describes the principles and management standards of organic production systems, and provides lists of substances that are allowed for use in organic production systems.

Organic production is based on the following general principles:
  • Principle of health – Organic production should sustain and enhance the health of water, soil, plants, animals, humans and the planet as one and indivisible.
  • Principle of ecology – Organic production should be based on living ecological systems and cycles, work with them, emulate them and help sustain them.
  • Principle of fairness – Organic production should build on relationships that ensure fairness with regard to the common environment and life opportunities.
  • Principle of care – Organic production should be managed in a precautionary and responsible manner to protect the health and well-being of current and future generations and the environment.

New Commercial Aquaponics Book by Dr. Wilson Lennard Now Available

Wilson Lennard is an Australian scientist with a PhD in Applied Biology. His thesis topic focused on the optimisation of commercial aquaponics systems. Dr. Lennard also has over 16 years of experience in the aquaponics industry. Here is a section from his preface that describes the purpose and focus of the book.

The purpose of this book therefore, is to not repeat the knowledge that is already available for standard, tank-based fish production (RAS) or standard hydroponic plant culture in detail, but to rather concentrate on the requirements of the integration process so as to produce the most efficient and optimised aquaponics designs and management methods available. This book wont therefore, go into upper level design and engineering aspects of the fish or plant culturing components of the aquaponic system design process. More detailed information may be found in other, excellent references and resources related to stand-alone RAS fish culture and stand-alone hydroponic plant culture. This book will concentrate on the application of science and engineering principals to the integration of these two existing technologies in a number of ways that meet the ultimate aquaponic outcome; the efficient and optimized use of the nutrient resources (i.e. fish feed) added to the system.

This book will also consider many of the satellite technologies associated with aquaponics, such as greenhouses, lighting, etc. However, and again, there are many excellent resources already available for these requirements, all of which go into far more exacting and complex detail than this book could attempt to do. Therefore, while these other technologies will be considered, it is more the purpose of this book to concentrate on the integration principles associated with fish and plant culture and so these other technologies are better served by trying to provide a list of appropriate external resources.

We hope to provide more details after we get our copy. You can purchase the book here.

Aquaponic Nutrients and the impact on Plant Production

Boris Delaide (University of Liège, BE) gave a presentation of his recent study of nutrients in aquaponics and their impact on lettuce production. Here are some key takeaways.

Aquaponics has a much lower level of nutrients than a typical hydroponic system, yet produces the same amount of lettuce

Most of the nutrient was lost due to the water changes and the sludge removal (solid fish waste removed from the system). Aquaponic systems need to take advantage of the nutrients locked in the sludge. Adding a digester to mineralize the solids is a good place to start.
Despite all of this, Aquaponics is as productive as an optimized hydroponic system with a much higher concentration of nutrients. This echoes the findings of others such as Nick Savidov.

His hypothesis is that aquaponics performs as well as hydroponics despite having less nutrients because of the microflora in the rhizosphere which help the roots in absorbing nutrients more efficiently. The second reason may be the dissolved organic matter may be feeding the plants directly or promoting the uptake of nutrients.
He also found that if the nutrients in the aquaponic system were supplemented so that they were equivalent to the hydroponic system, the plants would grow at a much faster rate than the hydroponic system.

Aquaponic solution supplemented with nutrients equalling what would be found in a typical hydroponic system, produced 39% more plant mass than the hydroponic system. This is due to the more efficient uptake of nutrients in the aquaponic solution.
Finally, he looked at different methods of digesting the sludge to release the nutrients that were locked in the solids. More work needs to be done in this area, but it is promising.

Aquaponics used to grow marijuana in former pulp mill in Nova Scotia

A Nova Scotia company will soon begin growing cannabis in a former pulp and paper mill in Queens County, and hopes the buy-local ethos extends to marijuana.

Health Canada granted Aqualitas Inc.'s cultivation licence Jan. 19, making it the third Nova Scotia company to get the approval — joining Breathing Green Solutions Inc., which has a production facility in the Wentworth Valley, and THC Dispensaries Inc. of Antigonish.

Myrna Gillis, co-founder and CEO, said Aqualitas plans to start growing its first crop in February and then it will test it and apply for a sales licence, with the hope of selling cannabis this summer. So far, none of the three Nova Scotia companies are licensed to sell.



As an early player in one of the largest per capita cannabis markets in Canada, Aqualitas aims to have all-natural, aquaponically-grown cannabis ready for market by this summer. The facility’s annual growth at capacity is projected at 9,000 kg and expansion into a further 20 acres beginning this June will move it towards its goal of becoming the largest licensed producer of all-natural cannabis in Canada.

Aqualitas has renovated a former Bowater warehouse in Liverpool, N.S., and has turned it into a 70,000-square-foot production facility. (Emma Smith/CBC)
Investors have also placed tremendous confidence in the company’s technological innovations, environmental values and most importantly, its team. Aqualitas recently closed an over-subscribed offering of common shares for total gross proceeds in excess of $8.8 million CAD.

The State Of Indoor Farming

The Agrilyst report looks at emerging trends, challenges and benefits of farming indoors. This year's report shows some interesting trends.

There is a growing number of indoor vertical farms since 2012.

Leafy greens remain the most popular crop.

Greenhouses have higher yields per area and are more profitable than vertical or container farms.





Aquaponics is the most profitable indoor growing technique among those surveyed!

The most significant operating cost in Aquaponics remains labour.
