What does the future of salmon farming look like in B.C.?

The Narwhal

The last open-net pen salmon farms in B.C. have until July 2029 to figure out a different way of doing business. Environmental advocates say the shift is long overdue but the industry warns the timeline is impossible. By Shannon Waters. This story is a collaboration with the newspaper The Guardian.

The Perils of Farming Salmon in a Warming World

The salmon farming industry presents itself as a sustainable solution to feeding humanity in a warming world. But as learned on a recent trip to Chilean Patagonia, intensive aquaculture practices can produce large negative environmental effects. By Jessica McKenzie

At sea as on land? Activists oppose industrial farming in U.S. waters

Mongabay

Agribusiness giants and other corporate interests are pushing to expand industrial finfish aquaculture into U.S. federal waters, arguing that it will help feed a growing global demand for seafood and have less environmental impact. They want Congress to pass legislation establishing a federal aquaculture system. Though Congress has not yet acted, a 2020 Executive Order is favorable to the effort. Environmental advocates are fighting against proposed congressional bills, and calling for a reversal of the executive order and a stop to the proposed projects in U.S. federal waters.

3 Reasons to Avoid Farmed Salmon

Time

Today, wild salmon are an endangered species, gone from most rivers in the U.S. There are many culprits, from polluted waterways and habitat destruction to overfishing and climate change. In the last 20 years, however, a new threat has emerged: floating feedlots on the ocean known as open-net salmon farms. The $20-billion-a-year farmed salmon industry is the world’s fastest growing food producer, and it has made farmed Atlantic salmon the most popular fish on dinner tables North America. But at what cost? By Douglas Frantz and Catherine Collins

Aquaculture Systems - A Basic Overview

UW-Stevens Point Northern Aquaculture Demonstration Facility

This video provides a basic overview of common aquaculture systems in the North Central region including ponds, raceways (flow-through), recirculating and aquaponics systems. Some of the systems shown are those located at the University of Wisconsin Stevens Point Northern Aquaculture Demonstration Facility. Other commercial farms and facilities are also utilized to explain various systems in the video, and are highlighted in the ending credits.

The Dangers of Industrial Ocean Fish Farming

Friends of the Earth

Many people opt for seafood over terrestrially-raised meat because they want better nutrition, a more humane option, and a smaller environmental impact. However, not all seafood is created equal. Much of our available seafood has been mass-raised and harvested in indus- trial ocean farms, pumped with agricultural drugs and pesticides, and provided feed comprised of overfished species, GMOs, and filler ingredients such as corn. In other words, the salmon on your plate could very well be unhealthy, inhumane, and unsustainable. Thankfully not all seafood production methods are bad, and you can continue to feel good about the fish you eat. There are many sustainable ways to produce seafood, including land-based recirculating farms, ocean-based farms utilizing entire water columns, and even some wild-caught fisheries.

Fishy Formula - Why the European Strategy Does Not Add Up to Sustainable Aquaculture

Food & Water Europe

The proposed benefits of increased food production via open water aquaculture (increased food production and job creation) are challenged by the darker side of the practice, including environmental damage, endangerment of wild populations, rampant use of antibiotics and harmful chemicals, job instability, and reliance on fish meal from wild populations. Investment in more sustainable forms of aquaculture, such as land-based recirculating aquaculture, small-scale shellfish aquaculture, and artisanal fishing and tourism would better serve communities.

Challenging the Aquaculture Industry on Sustainability

Greenpeace

Against a continuing background of diminishing and over–exploited marine resources, aquaculture has been widely held up as a panacea to the problem of providing a growing world population with ever-increasing amounts of fish for consumption. With the expansion of the industry, however, the tendency has been for methods of production to intensify, particularly in the production of carnivorous species. This has resulted in many serious impacts on the environment and human rights abuses. This report examines some of the serious environmental and social impacts that have resulted from the development and practice of aquaculture and which are reflected across the global industry.
