Aquaculture in Canada: 

Experienced and Innovative 

Canadian Closed Containment Fish Farmers

AgriMarine Recirculating Aquaculture Systems (RAS) are affordable, scalable systems. ATI is developing RAS technologies for applications where water access is restricted or where limited water resources are available for land-based farm production. RAS systems allow water quality of the rearing environment to be controlled, thus accelerating fish growth and crop turnover, while minimizing the entry of pathogens. Biofiltration, gas balancing, oxygenation, solids removal, UV and ozone disinfection and heat recovery are just a few features of the system 

Floating Semi-Closed Raceway Technology designed and delivered by ATI provides the same control over water quality as circular containment systems but can be deployed in smaller water bodies such as sheltered inlets, lakes, rivers, man-made ponds and rehabilitated gravel pits. The features are:

• Easy to implement, affordable systems
• Efficient use of limited water resources
• Control of dissolved oxygen levels, temperature and water velocity
• Biofiltration and oxygen enhancement
• Efficient removal of settleable solids
• Simplifies handling and grading fish

The high transfer efficiency oxygenation at low power is a challenge for farmers. Deepwater Injection Oxygenation System (DIOS) was developed to oxygenate water at a lower power consumption. Initially developed for fresh water applications, this system may be used in either fresh or ocean water. Key features of the DIOS:

• Provides a high transfer efficiency for oxygen supplementation
• Outfitted with adjustable ports that allow users to draw water from surface down to 30 metres depth, which provides temperature modulation and avoidance of deleterious biota at certain depths
• May be adaptable for a variety of applications to achieve the oxygenation needs of an individual site and species farmed

Typical oxygen stones corrode in ocean waters and are difficult to clean. Gas Diffusion Systems (GDS) are serviceable systems that can be taken apart during cleaning cycles and offer a full range of replacement parts. The diffusers are designed for many oxygen and gas transfer applications, from waste water to fish farming and everything in-between. Bubble creation is important for processes such as oxygenation in fish farms and finer bubble diffusers have been proven to provide the best solution for increasing oxygen transfer efficiency. The Micro Bubble Diffuser was designed by ATI for many oxygen and gas transfer applications. Robust and easily serviceable, Micro Bubble Diffusers feature ceramic membranes which are interchangeable and may be refurbished multiple times before replacement is necessary.

Key Features of the GDS are:

• Stainless steel housings which enables for indefinite operation in both salt and fresh water environments
• 50-micron-pore-sized ceramic diffusers
• Robust design for durability and 8kg weight ensures stability
• Diffusers with a 60 square inch surface area
• Bubbling pressure to a maximum 50 psi
• Lower pressure differential in order to save power
• Easy to install, dismantle, clean and replace

Axial 42” Aquaculture Pump -- Key Features of the Axial 42” Pump:

• Superior high performance Axial Pump
• Sophisticated design that transfers high volume water with low head
• With small size adjustments, the applications are unlimited (where large quantities of water are required to move with low head such as waterworks, water supply, drainage and irrigation)
• Pump efficiency up to 85%
• Durable and robust construction for long life
• Reliable and proven performance
• Diverse aquaculture applications

The AgriMarine 42” Axial Pump was custom engineered for low head/high capacity pumping requirements, typically in hatcheries and land-based recirculation systems (RAS), or where large amounts of water need to be moved. The pump may be engineered to suit your requirements, ensuring cost-efficiency and superior performance.

Cloud Based Autonomous Control of Aquaculture Systems -- This monitoring and control system provides remote user access for both monitoring and adjustment of rearing environment control systems. ATI developed the system to provide autonomous control of computers and equipment. The system ensures that computers can make rapid adjustments without the need for someone present at a farm site 24/7. Local data is uploaded to a cloud server which allows for remote access to data in real time, letting the farmer monitor a farm remotely, anytime of the day. Cloud servers send out text messages to farmers to alert them of any issues. 

Key Features of Cloud Based Autonomous Control system:

• Wireless communication between devices makes this system unique
• Modular set up allows easy incorporation into existing systems
• Monitors variables, sensors and pumps for instruments, and provides automated controls based on variables and parameters set
• Currently developing new wireless sensors that can be battery-powered and are easily connected without the need for power
• Data hosting is also available

AVCAM Live Feed Monitoring Camera -- Key Features of the AVCAM:

• AVCAM Camera offers high resolution under low light conditions
• Auto-switch from colour to black & white under low light
• Affordable, robust receptacle
• Permanent installation for hatcheries, rearing tanks and cages
• Live feed monitoring - AVCAM Camera connects to the AVCAM Camera Cart monitor
• Sharp video imaging

Feed management is integral to all aquaculture operations. ATI designed the AVCAM stationary underwater feeding camera with flexibility and efficiency in mind. Stationary cameras provide live feed monitoring with high visibility under low light conditions, so that farmers can easily detect uneaten feed.

In West Coast Fishculture (Lois Lake) Ltd., the ATI operations include growing Lois Lake Steelhead, a fish that is undeniably healthy, unbelievably tasty. 
Established in 1973, they continue to raise fish today with the same care and attention to detail that has made the Company well-known for quality and sustainability. Experience has taught that premium Lois Lake Steelhead is the result of the ideal combination of healthy broodstock, clean waters and carefully selected feed that meets the nutritional needs of their fish.

Lois Lake Steelhead conforms to the United Nations Food and Agriculture Organization’s Code of Conduct.  They have worked closely over the years with the Vancouver Aquarium’s OceanWise™ program which recommends Lois Lake Steelhead as a good alternative. These are the attributes that make the product unique. They are proud of the farm.
Against the backdrop of British Columbia’s majestic Coast mountains and surrounded by old growth forests and the ocean waters of the Strait of Georgia, the farm lies in the deep, cold, clean waters of Lois Lake, near the city of Powell River. The Lois Lake Steelhead are fed with high-grade sustainable feeds that contain high levels of Omega-3 and Omega-6 fatty acids. Reared in a stress-free environment, the Lois Lake Steelhead are harvested at approximately 5 lbs, processed in-house and immediately chilled to the core to ensure maximum quality and freshness.
The cycle of rearing and harvesting takes about 2 years. Eating BC-farmed Steelhead salmon ensures consumers will always be guaranteed a fresh, highly nutritional and flavourful fish that is reared sustainably in an environmentally friendly facility by people who are committed to working with the Vancouver Aquarium’s Ocean Wise™ program.

Unlike most farmed animals, there are absolutely no growth hormones used in the production of Lois Lake Steelhead salmon, Lois Lake Steelhead salmon is not given antibiotics in the feed, so the fish do not contain antibiotics. The fish are only fed with high-grade sustainable feeds.

The vital nutrients that give salmon a pink colour are included in the feed of Steelhead salmon and are called carotenoids. No artificial dyes are used. The deep, cold, clean waters of Lois Lake provide the ideal environment for raising excellent flavoured and textured salmon. Lois Lake Steelhead is regulated by federal, provincial and municipal authorities to ensure that they maintain the highest standard of environmental responsibility. Lois Lake's naturally high flushing allows for continuous cleaning and enables the company to raise Steelhead throughout the year, providing year round availability.

Here is the tank in operation, at AgriMarine's customers' site in Smøla, central Norway.  This is a Ctrl-Aqua test facility, where their tank was compared with competitors’ designs, and was judged the most suitable of the 3 designs tested.
