Organic vs. inorganic or nonorganic, terrorism vs. freedom and democracy, dirty oil vs clean, free range vs. feedlot, farmed salmon vs. wild.
These arguments seem so clear, so black and white, right and wrong, but there is one more that could be added to the list: pirate vs. privateer. If you were Spanish Francis Drake was a pirate (read evil) and if you were English he was a privateer, a man fighting to keep your country safe from the evil Spaniards.
Your perception of the issue will be different depending on what you think you already know about it. The language used to describe that issue will definitely play a part in how you perceive it, whether you know it or not. In this four-part series, I will take a look at some of these dichotomies of language that protesters, governments and industries use to sway public opinion.

Part 4 of 4 – Wild Salmon vs. Farmed Salmon
The idea of saving a wild animal pulls at the heart strings of humans. Saying “save the wild salmon” sounds like a great idea! But first you have to ask, are salmon in danger, and do they need saving? If so, from what?
As with everything on the planet, humans are having a negative effect on wild salmon. Is it any action in particular or is it a variety of issues? Logging, habitat destruction, pollution, overfishing, and fish farms all have effects. Is one more to blame than the others?
Logging, hydro dams and pollution
Logging has come under stricter regulations over the last 30 years or more and everyone seems to understand the importance of leaving trees around streams and rivers. Everyone one also knows that dumping industrial waste into rivers does not benefit anyone. Many hydro dams provide salmon ladders so that spawning salmon can return to their homes.
However, not all hydro dams have had their effects mitigated. In the United States, US Army Engineers spend millions of dollars each year to move salmon past the series of dams on the Columbia River in trucks. Does it help? We don’t know for sure.
Despite being called a source of “clean energy”, the debate over hydro dams continues and many believe dams in the Western US are largely responsible for the decline of salmon in Washington and Oregon. It is highly emotional, much like the debate over fish farms, and like that debate, while the language used is black and white, the actual causes and effects are not so clear.
Net pen salmon aquaculture
Alexandra Morton and the group Salmon Are Sacred certainly believe that fish farms are the cause of all the ills in the ocean. Working from the premise that cattle feedlots are bad for the environment and knowing that the term creates a mostly negative image in peoples minds, she coined the phrase “salmon feedlots” and that term is now widely used by B.C. media.
In 2009 she started a blog and commented on what she felt was a similarity between salmon farming and agricultural feedlots.
“The Norwegian salmon farming companies that operate in BC waters are perhaps the only farmers who never shovel their manure. It flows unimpeded into our ocean and with it the bacteria, viruses and parasites that brew under all feedlot conditions.”
In 2010 her use of the term feedlot becomes more focused until eventually, instead of being like feedlots, salmon farms are labelled as feedlots.
“We the undersigned stand against the biological threat and commerce of industrial net-pen feedlots using our global oceans.”
Prior to the use of the term feedlot the description for the salmon farming that happens off the coast of BC was “net pen salmon aquaculture.” But, let’s face it, feedlot is a lot easier to fit into a headline.
“She [Alexandra Morton] calls salmon farms “industrial salmon feedlots”. Ewwww…conjures up images of chickens stuffed in cages and pigs rolling in their own poo. Ewwww. (no offence to the hard working poultry and pork farmers of this world).”
Morton can’t seem to get her opinion out strong enough with “feedlot” so she adds “industrial” to the front to make it even more “evil” (because, as we know, industry is out to destroy the world).
As discussed in the other parts of this series, if animals (or fish) are kept in unsanitary or stressful situations they will not grow. If they don’t grow, farmers don’t profit. There is no profit in harming your own stock.
Is feedlot a valid description of net pen aquaculture?
One image the term feedlots brings to mind is a large number of animals (or fish) crammed into a small enclosure. This paper takes a fair look at aquaculture and has some interesting points to make about stocking density.
CLOSED WATERS: THE WELFARE OF FARMED ATLANTIC SALMON, RAINBOW TROUT, ATLANTIC COD & ATLANTIC HALIBUT
Written by Compassion in World Farming and the World Society for the Protection of Animals in 2007
Maximum stocking density
It is important not to stock up to a theoretical maximum but instead to provide a safety margin so as to ensure that, even when problems arise, fish continue to have good water quality and sufficient space for swimming. Farmers are not in control of all the factors – such as water quality and bad weather – that can adversely affect the fish. A safety margin is important to allow for harmful developments.
Recent research shows that above 22kg/m3, increasing density is associated with lower welfare for caged Atlantic salmon. However, in order to provide a safety margin, CIWF and WSPA believe that the maximum stocking density for Atlantic salmon in sea cages should ideally be 10kg/m3, with farmers who achieve a high welfare status and in particular low levels of injuries, disease, parasitic attack and mortality being permitted to stock up to a maximum of 15kg/m3.
Net pens in BC farm at a density that is between 15kg/m3 and 20kg/m3, and try to keep it as low as possible, which, as this study suggests, is optimal. In fact, for each net pen, only 3% of volume of pen is taken up with fish. This is far from the image of feedlots and battery chickens that Ms. Morton and her ilk try to portray.
Ms. Morton and others claim that closed containment is the only choice for the future of salmon farming, while ignoring the fact that farming fish on land on a large scale would be more “industrial” than farming them in the ocean. They seem to blissfully ignore the environmental costs of using agricultural or forest land for industrial purposes, as well as the amount of fresh water that would be required, the energy usage or the environmental cost of trucking and disposing of fecal matter.
When the word industry is Googled under images you see hundreds of photos of smoke stacks and factories. Which seems more “industrial:” a net pen floating in the ocean with a 3% volume of population per net or a land-based factory requiring hundreds of acres of developed land?
Current closed containment projects are being held up as examples for the future of the industry but every discussion about taking the industry out of the ocean completely ignores the land use problems. Current successful land based farms grow 100 tonnes of fish. One net pen site in the ocean grows 3000 tonnes. Take one of these land sites and increase them 30 times and you will get one net pen farm. There are many farms currently in the ocean and they do not have anywhere near the impact that land-based sites of equivalent capacity would have.
It is also seldom noted by opponents of net pen farming that the salmon spend the first third of their lifetime in a land-based facility. No one knows better than the fish farming companies about closed containment technologies, and the limitations of the technology, than the industry because they have been using it since the beginning.
Everything humans do affects the environment. Salmon farms are no exception. However, when all the human factors are looked at, it seems highly unlikely that salmon farms caused the decline of salmon runs on the west coast. An unhealthy ocean would mean an unhealthy farm. An ocean without wild salmon would be an unhealthy ocean and this is not something salmon farmers want to see happen.
Before I learned about salmon farming I learned about the collapse of the commercial cod fishing industry on the east coast. Overfishing removed fish from the ocean so there were fewer left to spawn and fewer that would be there for next year’s catch. Farmed fish (salmon being my favorite) seems a good solution.
It should be noted that fish meal and fish oil are used in fish feed. It is obtained from “forage fish… [which] are fast-growing and short-lived fish not generally used for human consumption.”
“Ocean-farmed salmon feed comprises about 30% fishmeal, a name for the otherwise unused forage fish that is converted to food. Salmon feed represents nine percent of the world’s fishmeal consumption, otherwise used for fertilizer or livestock and poultry feed…The Food & Agricultural Organization of the United Nations confirms that forage fish are not over-fished or depleted.”
This is a concern, but I also learned that salmon farmers, and farmers of other types of fish, are working very hard to reduce the amount of fish meal and oil in fish feed. And the amount of small fish harvested to use in fish feed, poultry and hog feed, and health supplements has not changed in decades, despite a growth in aquaculture around the world.
This is a good use of resources because salmon are incredibly efficient eaters.
|Ratio of feed required to edible food produced (pounds)|
|Wild Salmon||10 : 1 or 15 : 1*|
|Beef||10 : 1|
|Pork||5 : 1|
|Chicken||2 : 1|
|Ocean-Farmed Salmon||1.5 : 1|
|*Varies depending on mortality rates and feeding|
Many groups feel that one way to save the oceans is to not buy farmed salmon for dinner but buy wild salmon instead. Hold on a minute, to save the wild salmon we need to kill and eat them, thus preventing their ability to spawn and removing them from the gene pool? This is cognitive dissonance if ever I saw it.
For most people commercial fishing is their source for wild salmon. If terms such as “industrial” or “factory” are considered negative when discussing farming why not when discussing fishing?
Contemporary factory ships have their origins in the early whalers. These vessels sailed into remote waters and processed the whale oil on board, discarding the carcass. Later whalers converted the entire whale into usable products. The efficiency of these ships and the predation they carried out on whales contributed greatly to the animal’s precipitous decline.
Contemporary factory ships are automated and enlarged versions of these earlier whalers. Their use for fishing has grown dramatically. For a while, Russia, Japan and Korea operated huge fishing fleets centred on factory ships, though in recent times this use has been declining. On the other hand, the use of factory ships by the United States has increased.
Some factory ships can also function as mother ships. The basic idea of a mother ship is that it can carry small fishing boats that return to the mother ship with their catch. But the idea extends to include factory trawlers supporting a fleet of smaller catching vessels that are not carried on board. They serve as the main ship in a fleet operating in waters a great distance from their home ports.
Greenpeace uses some very descriptive language to explain factory fishing.
“Beneath the serene beauty of our ocean waters lurks a nightmare worse than any Jaws movie. You could compare it to alien abduction – massive numbers of fish are being snatched out of the water by high-tech factory fishing trawlers. This nightmare scenario is real, and the impacts on our ocean’s ecosystems are extensive. Entire populations of fish are being targeted and destroyed, disrupting the food chain from top to bottom.”
Commercial whaling caused the decline of whales, these types of ships are now used for fishing. Would it not make sense that they will also cause the decline of wild fish stocks?
Sea Choice is a sustainable seafood program that supports Alaskan fishing over over B.C. fishing and salmon farms.
“Salmon (Chinook, Chum, Coho, Pink, Sockeye) From: U.S. – AK Method: Wild, drift gillnet, purse seine, troll
Pacific salmon in Alaska is among the most intensively managed species in the world, with excellent monitoring of both the fish populations and the fishery. Alaskan salmon dominates the West Coast salmon market. Over the past 20 years, Alaska has landed roughly 10 times as much salmon as California, Oregon and Washington combined.”
How is catching 10 times more salmon better for the environment? How is catching that many salmon sustainable?
Alaska has a hatchery program that is very different from what we are used to in B.C. Here smolts are released into a river or stream with the hope that they will grow to maturity and return to spawn. In Alaska there is a process called salmon ranching, which is also referred to as salmon enhancement. The problem with this enhancement is that it is not for the purpose of saving the wild stocks and growing the population, instead it enhances the commercial fishery and allows for the 10 times greater catch.
Simply put, salmon ranching refers to a process by which indigenous salmon are initially caught and stripped of eggs and milt. The fertilized eggs are then cultured in a hatchery where they will hatch and begin feeding on a feed powder. Mimicking the natural life cycle of a wild salmon, these salmon are then transported from freshwater hatcheries to saltwater fish farms. The juvenile salmon continued to be cultured in saltwater fish farms using net pens to contain the salmon. While in net pens, salmon are fed feed pellets to gain size and strength. Also, by remaining captive in an area suitable for a future commercial fishery, the salmon are “imprinted” to the area where they are temporarily farmed. Imprinting ensures that these cultured salmon return to the same place where they were “born” – similar to natural, wild salmon. Once large enough to successfully compete with wild salmon for food and space, these cultured salmon are released into the ocean to forage for food (referred to as “ranching”). Depending on the species of salmon (Pink, Chum, Coho, Chinook or Sockeye), they will return to their birthplace in two to four years. Upon return, a mixture of wild and ranched salmon are caught by commercial and sports salmon fisherman. Selected salmon are also retained by the source hatchery to be used again for eggs and milt – thus repeating the process.
See a video of this process here.
The beginning two thirds (or so) of life for these ranched fish is exactly the same as farmed fish. How is releasing them for the last year of their life more sustainable?
There are some opponents of this practice but not nearly as many as oppose BC fish farms. As mentioned in the posting Transparency some of the money that goes into these campaigns against fish farms in BC (such as the David Suzuki Foundation) comes from groups who support the Alaskan commercial fishery and it’s ranches. To try and say they have the best interests of the environment at heart is a double standard.
Here is one article talking about the drawbacks of this kind of salmon rearing written in Oct. 2010:
“We hear so much about missing wild salmon and recently a record run. But Simon Fraser University scientists say a population explosion of hatchery and wild salmon in the North Pacific Ocean is leading hatchery fish to beat out their wild cousins for food…“Higher levels of hatchery fish straying onto spawning grounds, combined with low numbers of wild fish, could further erode wild salmon diversity, which helps stabilize their abundances,” explains Peterman. “Many salmon from both sides of the Pacific intermingle in the Gulf of Alaska, Bering Sea and/or south of there. Together, these factors create the perfect storm for reducing wild salmon over the long term.”
Here is another, also written in Oct. 2010:
“We’ve been down this road before, in salmon country further south. I watched Oregon’s salmon economy crash after a failed reliance on hatchery-produced salmon. Oregon and Washington are now busy reforming salmon hatcheries, after learning the hard way that a salmon economy built on hatchery fish is a house of cards.”
If the practice of salmon ranching were stopped in Alaska, the Alaskan fishery would collapse and people would be shocked about how few salmon are left.
Alternatively, the Sea Choice guide says:
“Freshwater habitats in Alaska have remained relatively pristine, and salmon originating in Alaska does not face the same damming, deforestation and development challenges as those in California and the Pacific Northwest. The current abundance of Alaska salmon and its habitat reflects the success of the state’s management practices. For these reasons, wild-caught salmon from Alaska is ranked as a “Best Choice.”
B.C. does face the development challenges mentioned and because of this Sea Choice does not recommend salmon caught in B.C. waters. It doesn’t seem to me that the abundance in Alaska has as much to do with the state’s management practices as it does with the abundance of salmon ranching in the state.
What Sea Choice does not point out is that the fish which spawn in B.C. rivers travel through international boundaries to the northern pacific, where they are taken from the ocean by American fishermen and sold as an American product.
What is sustainable seafood?
Is wild salmon the best choice for dinner? How was it caught? Where was it caught? How much fuel was used to catch it and deliver it? What percentage of the wild stock was directly destroyed by that catch?
Sustainable is a word used by people on both sides of these protests, but what does it mean? The Google dictionary explains it this way: 1. Able to be maintained at a certain rate or level. (esp. of development, exploitation, or agriculture), 2. Conserving an ecological balance by avoiding depletion of natural resources. Industry Canada explains it this way:
Sustainable development’s most common definition is “a development that meets the needs of the present without compromising the ability of future generations to meet their own needs”, from the United Nations study which first brought this issue to the world’s attention more than twenty years ago (Our Common Future, The World Commission on Environment and Development – Brundtland Commission, 1987). It is an approach to growth that considers the impacts of policies, programs and operations on economic prosperity, environmental quality and social well-being.
Which is more sustainable; an industry that directly kills a population by removing it from the ocean or an industry that strives to have as low an impact on the ocean as possible but is still able to provide a fresh product all year long?
