The Problem … Fish farming, as currently practiced, has a

number of real and/or perceived social and

environmental issues.

• Nutrient/Waste Effects

• Sea Lice Interaction

• Fish Escapes

• Effects of Antibiotics

• Feed Composition

• Fossil Fuel Usage

Sustainable Ecological Aquaculture ?

SEA … an approach that

achieves the goal of

Sustainability by using the

principles of Ecology in its

design and operation. Environmental

Our first SEAfarm

Farm Site

British Columbia

CANADA Located along the northern shore

of Surprise Island in Kyuquot

Sound, this farm has served as the

pre-commercial R&D site for our

SEAfood System. It now holds

the first commercial

aquaculture

license of its

kind in Canada.

System

Benefits

• Product diversification

• Improved environmental

performance

• Reduced operating risk

with multiple species

• Reduced CoP with shared

labour pool, SEA- Power

and SEA-Hatchery

• Organic approach –

meets growing market

demand

Market

Potential

• Increasing seafood demand

globally (>2.5% annually)

and growing per capita

consumption in North America

• Growing Eco-ethical consumer

base looking for fresh,

sustainable, wholesome food

choices – and willing to pay

(organic niche)

• Prices of high-valued species

projected to continually

increase (>20% by 2020)
