Leaders of Commercial Aquaculture Technologies
AgriMarine Recirculating Aquaculture Systems (RAS)
AgriMarine Technologies Inc. (ATI) is a Canadian-based leading designer
and innovator of aquaculture systems, dedicated to the development of
sustainable, innovative technology systems and solutions for commercial
aquaculture applications around the world.
The Company develops land-based, recirculating aquaculture systems (RAS) to create
optimal fish rearing environments with economic and environmental benefits. Our
systems are designed for applications where water access is restricted or where limited
water resources are available for land-based farmed production.
Since 2000, ATI has gained valuable knowledge in the economic construction of large-scale
tanks, in the management of water flows, fish husbandry and in the development of patented
rearing technologies, which gives the Company an immediate market edge. We work in
conjunction with leading biotechnology professionals to design, source and construct the
most advanced RAS systems and components available.
Our team of engineers works with each client
to design and build optimized rearing facilities
with tailor-made solutions for a wide range of
aquaculture species. From feasibility studies, to
site selection reports, project and construction
management and installation, AgriMarine
works with clients who want to improve their
sustainability and profitability through the
application of innovative technology.
Designing Innovative Aquaculture Solutions
RAS are land-based, closed containment rearing systems with full water
treatment and recycling technologies employed, that offer economic and
fish husbandry benefits to the farmer. RAS has been used for fish farming
for over 20 years in hatcheries and grow out systems for a wide variety
of species. Increased demands for farmed fish combined with the
challenges of access to new open water culture sites for traditional
fish farming are now causing this market to explode.
RAS allows water quality of the rearing environment to be controlled, thus
accelerating fish growth and crop turnover, while the entry of pathogens is
minimized, as only small make up water flows need be treated.
The discharged water carrying nutrients goes through a series of purification and regulation
treatments before being partially or totally reused. Water treatment processes include
solids removal (waste and uneaten feed), bio-filtration, gas balancing, oxygenation, and
disinfection. For example, the high water quality is achieved by using drum filters,
bio-filters, ultraviolet sterilization for pathogen control, as well as ozone filtration.
Key Features of RAS:

Fish products can command premium pricing
Improves feed conversion ratios
Optimizes growth rates
Provides a consistent biomass once steady-state is reached
Increases bio security
Controls water temperature and salinity levels.
Lowers carbon footprint for farms that are close to markets
Designed for fish production from hatchery to grow-out
Innovation – Vision – Performance
ATI has two RAS concepts to meet the needs of a variety of projects,
fish species and rearing environments:
1. Circular Tanks
2. Mixed Cell Raceways
Housed in a bio-secured building, a typical
design layout would include a set of nursery
tanks, circular rearing tanks, and a set of
purge tanks. Internal bio-filter, solids removal
and emergency oxygen panels are included.
A modular design can be duplicated for
increased rearing volume.
The Mixed Cell Raceway design is comprised
of nursery tanks, grow out raceways, purge
tanks and water quality control systems (biofilter, solids removal, emergency oxygen). A
greenhouse-style building is required. This
type of system is also modular and may be
expanded for future business growth. Typically,
the mixed cell raceway concept is less costly to
build and operate, whereas global experience
with round tank systems is more common.

Client Strategy
ATI customizes designs to meet the specific needs of our clients, for
a variety of species and rearing environments, anywhere in the world.
Working with aquaculture projects requires a streamlined and structured
process for successful execution with minimal interruption to ensure
timelines and budgets are met.
We outline our general process:
1. Pre-Design Phase: Feasibility Study and Permitting
This phase of work will consist of all design, engineering and consultant contract services as
required to fully design and cost estimate the project in detail such that a full feasibility study
report is produced for analysis.
3. Project Implementation
In this phase we will:
• Manage all aspects of the project, including budgeting, planning, construction and
installation of land-based operations.
• Develop a site specific farm management system development, including sourcing of local
suppliers, tradespeople and labour, brood stock and feed.
• AgriMarine will provide logistics support, engineering and physical plant support during
the development period, training, maintenance, husbandry services and animal health
management services on an agreed upon fee for service basis.
Management Support Stages and Services Available
1. Provide production planning for aquaculture systems for desired production targets.
2. Stocking and breeding of fingerlings or liaise with hatcheries for supply.
In this phase, our team will:
• Complete a full analysis of the location of the project, water and power sources, local climate, fish species, and desired production to define CAPEX and OPEX cost estimates.
• Draft a design to suit our client’s production goals and CAPEX budget or design to define the CAPEX if no budget has been set.
• Once the estimated capital cost is established, we will conduct a feasibility study and predict working cash flow OPEX estimates.
• The final construct and budget plans will be presented to our client for final approvals. Should the project be approved for funding and execution,
additional design and service management support will be provided to all
for permitting of the project to allow the implementation phase of the
project to commence. ATI will provide this service under an agreed fee
for service scope of supply.
2. Design and Engineering
• In this phase, we will meet all the criteria of the pre-design
phase, including the engineering, consulting and project
management services to implement the project.
3. Develop and carry out disease management strategies.
4. Feeding, nutrient and harvest scheduling and market sales if required.
5. Train farm labor and key staff in the husbandry and management of the farming systems.
How May We Help You?
To get started, we encourage you to make contact to outline your ideas. We will
respond with clarifying questions and arrange a time to discuss in person.
Information we may need to get started:
• Have you decided upon species?
• Have you decided upon production capacity?
• Have you set a capital expenditure budget and are these funds
available now?
• Have you suitable land available and if so what area is
available for use?
• Have you adequate and stable supply of
electricity for the additional load from
the proposed farm?
• Have you adequate, secure water
supply for the farming
activities?
