Canada’s Shrimp Industry: A Cold-Water Success Story Rooted in Innovation, Sustainability, and Coastal Identity

Canada’s shrimp industry is one of the country’s quiet powerhouses—an economic engine for coastal communities, a global leader in sustainable fisheries management, and a remarkable example of how science and industry can work together to steward marine resources responsibly. While lobster and salmon often dominate the spotlight, shrimp—especially cold-water northern shrimp and the increasingly important cold-water Pandalus borealis and Pandalus montagui species—play an equally vital role in Canada’s seafood landscape.

This article explores the history, biology, economics, sustainability practices, and future of Canada’s shrimp industry, offering a comprehensive look at why this sector matters more than ever.

A Fishery Built on Cold Waters and Coastal Expertise

Canada’s shrimp industry is concentrated in two major regions:

• Atlantic Canada (Newfoundland and Labrador, Nova Scotia, New Brunswick, Prince Edward Island)

• The Eastern Arctic (Nunavut, Nunavik, and offshore northern waters)

These cold, nutrient-rich waters create ideal conditions for northern shrimp—small, sweet, and prized for their delicate flavour. Unlike warm-water shrimp farmed in tropical regions, Canada’s shrimp are wild-caught, making them part of a long-standing fishing tradition.

A Brief History

The commercial shrimp fishery began to expand in the 1970s, driven by:

• Advances in trawling technology

• Growing international demand

• The establishment of Canada’s 200-mile Exclusive Economic Zone

By the 1990s and early 2000s, shrimp had become one of the most valuable fisheries in Atlantic Canada, especially as groundfish stocks declined. For many communities, shrimp became a lifeline—supporting jobs, processing plants, and local economies.

Understanding the Species: Why Northern Shrimp Are Unique

Canada’s shrimp industry primarily harvests:

• Northern shrimp (Pandalus borealis)

• Striped shrimp (Pandalus montagui)

These species thrive in deep, cold waters and grow slowly, which makes sustainable management essential.

A Fascinating Biological Twist

Northern shrimp are protandrous hermaphrodites—they begin life as males and later transition to females. This life cycle has major implications for fisheries management, as harvesting too many large individuals (typically females) can disrupt population dynamics.

Canada’s science-based approach accounts for this, ensuring long-term stock health.

Economic Importance: A Lifeline for Coastal Communities

Shrimp is one of the most valuable seafood exports in Atlantic Canada. The industry supports:

• Thousands of jobs in harvesting, processing, and logistics

• Dozens of coastal communities, particularly in Newfoundland and Labrador

• Indigenous-owned enterprises and co-management agreements

• A robust export market, especially to the U.S., Europe, and Asia

The Role of Processing Plants

Shrimp processing is labour-intensive and often the backbone of rural economies. Plants in Newfoundland and Labrador, for example, have historically provided stable employment for communities with few alternative industries.

Shrimp shells—once considered waste—are now a valuable feedstock for chitin and chitosan production, opening new opportunities in biotechnology, agriculture, and pharmaceuticals. This shift toward full-shell utilization is transforming the industry’s sustainability profile.

Sustainability: Canada’s Global Leadership

Canada is widely recognized for its rigorous fisheries management. The shrimp industry is no exception.

Key Sustainability Measures

• Quota-based management informed by scientific stock assessments

• Individual transferable quotas (ITQs) for offshore fleets

• Seasonal closures to protect spawning periods

• Strict bycatch reduction measures, including Nordmøre grids

• Ecosystem-based management that considers climate impacts

• Indigenous co-management in northern regions

Many Canadian shrimp fisheries have earned Marine Stewardship Council (MSC) certification, a globally respected sustainability standard.

Climate Change: A New Challenge

Warming waters in the Northwest Atlantic have affected shrimp distribution and abundance. In some areas, shrimp stocks have declined while species like snow crab have increased. This shift underscores the need for adaptive management and ongoing scientific monitoring.

Offshore vs. Inshore: Two Distinct Sectors

Canada’s shrimp industry includes both offshore factory freezer trawlers and inshore vessels supplying local processing plants.

Offshore Sector

• Large vessels capable of processing and freezing shrimp at sea

• Operate year-round in deep waters

• Highly efficient and export-oriented

• Often operate under ITQ systems

Inshore Sector

• Smaller vessels fishing closer to shore

• Supply fresh shrimp to land-based processing plants

• Provide significant local employment

• More sensitive to quota fluctuations

The balance between these sectors has been a long-standing policy discussion, especially in Newfoundland and Labrador, where inshore shrimp supports rural communities.

The Rise of Cold-Water Shrimp on the Global Stage

Canadian shrimp is prized internationally for its:

• Sweet flavour

• Firm texture

• Wild-caught origin

• Traceability and sustainability credentials

Major markets include:

• United States

• United Kingdom

• Denmark (a major reprocessing hub)

• China

• Japan

As consumers increasingly seek sustainable seafood, Canada’s shrimp industry is well-positioned to grow—provided stocks remain healthy and climate impacts are managed.

Innovation: From Shrimp Shells to High-Value Bioproducts

One of the most exciting developments in Canada’s shrimp industry is the emergence of value-added bioproducts derived from shrimp shells.

Chitin and Chitosan Production

Shrimp shells contain:

• Chitin, a structural biopolymer

• Proteins and minerals

• Carotenoids like astaxanthin

Through demineralization, deproteinization, and deacetylation, chitin can be converted into chitosan, a versatile biopolymer used in:

• Water treatment

• Agriculture

• Wound care

• Pharmaceuticals

• Cosmetics

• Bioplastics

Canada’s cold-water shrimp shells are exceptionally pure, making them ideal for high-grade chitosan production. Facilities like the one in St. Anthony, Newfoundland and Labrador are pioneering sustainable, science-driven approaches that turn what was once waste into a globally competitive product.

This shift toward circular bioeconomy principles is redefining the industry’s future.

Challenges and Opportunities Ahead

Challenges

• Climate-driven stock fluctuations

• Competition from low-cost warm-water shrimp

• Labour shortages in processing plants

• High operating costs for inshore fleets

• Market volatility

Opportunities

• Expansion of chitin and chitosan production

• Growth in sustainable seafood markets

• Indigenous-led fisheries and processing

• New technologies for selective harvesting

• Eco-certification and traceability systems

• Development of shrimp-based nutraceuticals and bioproducts

Canada’s shrimp industry is evolving from a traditional fishery into a diversified, innovation-driven sector.

Conclusion: A Fishery Rooted in Tradition, Powered by Innovation

Canada’s shrimp industry is far more than a seafood sector—it’s a story of resilience, scientific stewardship, and community identity. From the offshore trawlers of the Grand Banks to the processing plants of Newfoundland’s Northern Peninsula, shrimp has shaped livelihoods and supported regional economies for decades.

Today, the industry stands at a crossroads. Climate change presents real challenges, but innovation—especially in bioproducts like chitin and chitosan—offers extraordinary potential. With strong science, sustainable management, and continued investment in coastal communities, Canada’s shrimp industry is poised to remain a global leader for generations.
