There are two videos and one article (although a quick internet search will result in many more written articles) dealing with the Salmon crisis in BC. There are a variety of ways of using this information and it can be tied back to a number of objectives in the SVN3M and 3E courses – which I have included – the orange comments are mine, everything else has been lifted from the Ont Curriculum policy. What I like about this issue is that there are tangible efforts that the students could make in trying to effect change – they can educate the public wrt the impact of consuming farmed fish, they could write letters to the Dept Of Fisheries and Oceans as well as to Stephen Harper and the BC Premier,

Big Ideas:
Sustainable Agriculture and Forestry
Modern agricultural and forestry practices can have positive and negative consequences
for the economy, human health, and the sustainability of ecosystems, both local and global.
SVN3M Objectives that could be covered by this issue:
B1.1 analyse, on the basis of research, social and
economic issues related to a particular environmental
challenge (e.g., overfishing, deforestation,
acid rain, melting of the polar ice
B2.3 investigate, through research or using case – the in depth video shows how a scientist takes data from the field and creates a research paper submitted to (and published in) top scientific journals
studies or computer simulation, how scientific
knowledge and procedures are applied to address
a particular contemporary environmental issue
(e.g., scientific data on the needs and habits of
endangered species are used to develop plans
to protect threatened species; life-cycle assessments
are conducted to determine the total
environmental impact of a consumer product)
B2.5 use a research process to locate a media (any search for missing Fraser Salmon will result in numerous articles)
report on a contemporary environmental issue
(e.g., climate change, melting of the polar ice cap,
deforestation), summarize its arguments, and
assess their validity from a scientific perspective

B3.1 identify some major contemporary environmental – MILLIONS OF SALMON missing from the Fraser is a VERY contemporary issue
challenges (e.g., global warming, acid
precipitation), and explain their causes (e.g.,
deforestation, carbon and sulfur emissions)
and effects (e.g., desertification, the creation of
environmental refugees, the destruction of
aquatic and terrestrial habitats)
B3.5 describe a variety of human activities that have – The practice of farming exotic species in pristine environments
led to environmental problems (e.g., burning fossil
fuels for transportation or power generation;
waste disposal) and/or contributed to their solution
(e.g., the development of renewable sources
of energy; programs to reduce, reuse, and recycle)
SVN3E Objectives:
B1. analyse selected current environmental problems in terms of the role human activities have played
in creating or perpetuating them, and propose possible solutions to one such problem;
B3.5 explain the effects of human activity (fish Farming) on an
aquatic or terrestrial ecosystem (e.g., the impact
of fertilizer run-off, acid precipitation, or an oil
spill on an aquatic ecosystem)

Only one out of ten of the expected bright-red sockeye salmon showed up at Canada’s Fraser River to spawn this summer. Some marine biologists attribute the deaths to the growing number of commercial fish farms that governments on both sides of border have allowed to open.

More than 10 million sockeye were expected to return to the Fraser, but less than 1 million showed up, according to government fish counters.
So what does this mean to consumers?
Of the five major salmon species sold to shoppers and restaurants, fish mongers tell me that most people seem to prefer the sockeye, which is sometimes called Red salmon because of its mild flavor and deep red color.
Sockeye almost always sells for less than the top-of-the-eating-line King salmon.
Canadian Broadcasting reported today that major fish sellers have just about run out of fresh sockeye. But I checked with the Wild Salmon Seafood Market at Seattle’s Fisherman’s Terminal, and they say they can get all the sockeye they need “so far.”
Stan Proboszcz, a fish biologist with “Watershed Watch Salmon Society” told me today that the cause of the sockeye kill-off might be attributed to a marine parasite.
Other environmental activists and some academics agree that the 90 percent drop in the Fraser’s sockeye population can be blamed mostly on sea lice.
These parasites are found in very high concentrations around the sprawling commercial fish farms of Georgia Strait, which runs 170-miles north from the Strait of Juan de Fuca — which separates the U.S. and Canada – to the northeast coast of Vancouver Island.
Proboszcz explained that the juvenile salmon leaving their fresh water birth site — the Fraser River — for the Pacific, soon run into the sea lice from the floating fish farms. The lice attach themselves to the fish and feed on their blood and skin.
The parasites are not unique to the Pacific Coast.
Fish biologists in Maine and in countries bordering the cold waters of the North Atlantic have reported the same problem, that billions of lice can be generated by a single floating salmon farm.
Proboszcz says that while a few lice on a large salmon may not cause serious damage, just a couple on a juvenile salmon, can be harmful or fatal.
Fisheries and Ocean Canada, which, does little to control the hazards from fish farming, has the same conflict of interest that face U.S. agencies, Proboszcz says.
Both groups are tasked with ensuring the health of wild salmon, but also with promoting more commercial aquaculture.
Other causes including over-fishing or an increase in water temperature may add to the sockeye’s demise, the experts say.
Both the B.C. and Washington State governments have approved the construction of more fish farms so the parasite problem, and other harmful spin–offs of the industry, may become worse.
