High school kids learn about aquaculture with tilapia

Magnet Cove High School learn about aquaculture by raising tilapia

MALVERN, Ark (KTHV) — Students at Magnet Cove High School are raising tilapia in the classroom. It’s all part of a 6 week project for their aquaculture class.

Magnet Cove teacher Kristyn Sheets saw an opportunity when she came to Magnet Cove two years ago. The school already had a tank system in place for the fish, they just needed a teacher and students willing to get their hands wet.

Sheets says it took off from there. She says, “This is just application of knowledge instead of worksheets and textbooks. When we have all of these toys and all of these hands-on things this is where our classrooms should be.”

Learning by doing; something science has always encouraged students to do and the aquaculture Corey Stanley is liking the innovative style of teaching. “At the start of the year we took notes and stuff about different types of fish. Now, were getting really hands-on. That’s my favorite part about it. I love to study a fish, but hands on is really fun,” says Stanley.

Sheets says, they’re learning a lot in the process. She adds, “This year we’ve set up a project where the students are completely in charge of managing the water quality, they weighed fish on Thursday, they have to monitor all of the feed, so they can figure out feed conversion ratios and percent gain and they’re doing all of that because they have the tools to do that.”

The two large fish tanks are housed within the schools greenhouse and algae is grown as a second crop inside the tanks. Student Dustyn Parker says water quality is the main priority. “I have learned how to do testing for dissolved oxygen, PH levels. I’ve learned that fish don’t eat all the time and they have certain times that they eat. Some days they won’t eat due to the weather and how the weather effects them,” says Parker.

Sheets, says she’s proud of her students and what they’ve accomplished so far. She says, “They might mess up some things and it’s going to be ok, they’re going to learn from it. They’re not going to get a lot of worksheets, they’re not going to get a lot of traditional class work type of grades. They’re going to get grades on if their fish live or die.

Petition Seeks International Investigation of Canada’s Farmed Fish Operations, Protections for Wild Salmon

NAFTA Panel Asked to Investigate Canadian Violation of Wildlife Law

SAN FRANCISCO— Conservation, fishing and native groups in Canada and the United States filed a formal petition today requesting an international investigation into Canada’s failure to protect wild salmon in British Columbia from disease and parasites in industrial fish feedlots. The petition was submitted to the Commission for Environmental Cooperation under the North American Agreement on Environmental Cooperation — an environmental side agreement to the North American Free Trade Agreement — and seeks enforcement of Canada’s Fisheries Act.

“The Canadian inquiry into the collapse of Fraser River sockeye, the largest salmon-producing river in the world, suggests the primarily Norwegian-owned British Columbia salmon-farming industry exerts trade pressures that exceed Canada’s political will to protect wild salmon,” said biologist Alexandra Morton with the Pacific Coast Wild Salmon Society. “Releasing viruses into native ecosystems is an irrevocable threat to biodiversity, yet Canada seems to have no mechanism to prevent salmon-farm diseases from afflicting wild salmon throughout the entire North Pacific.”

Canada has permitted more than 100 industrial salmon feedlots in British Columbia to operate along wild salmon migration routes, exposing ecologically and economically valuable salmon runs to epidemics of disease, parasites, toxic chemicals and concentrated waste. The petition documents Canada’s failure to enforce the Fisheries Act in allowing industrial aquaculture to erode the capacity of ecosystems to support wild salmon. The proliferation of salmon feedlots is linked to dramatic declines in British Columbia’s wild salmon populations and the detection of a lethal salmon virus.

“Fish farms in Canada are an unholy marriage between various levels of the Canadian governments and foreign-owned companies,” said Chief Bob Chamberlain of the Kwikwasu’tinuxw Haxwa’mis First Nation. “We continue to explore, identify and act upon whatever means possible to rid our traditional territories of open net cage fish farms.”

“The Canadian government’s disregard for wild salmon stocks in pandering to multinational salmon farming corporations is outrageous,” said Zeke Grader, director of the Pacific Coast Federation of Fishermen’s Associations. “Salmon feedlots put wild salmon, the communities that depend upon them, a billion-dollar fishing industry, tens of thousands of fishing jobs, and our nations’ shared natural heritage at risk of extinction.”

“Industrial salmon feedlots function as disease-breeding factories, allowing parasites and diseases to reproduce at unnaturally high rates,” said Jeff Miller with the Center for Biological Diversity. “Marine feedlot waste flows directly, untreated, into contact with wild salmon. Putting feedlots hosting a toxic soup of bacteria, parasites, viruses and sea lice on wild fish migration routes is the height of biological insanity.”

When a country signatory to NAFTA fails to enforce its environmental laws, any party may petition for enforcement. Canada’s Fisheries Act prohibits harmful alteration, disruption or destruction of fish habitat or addition of “deleterious substances.” The petitioners seek an investigation and finding by the Commission for Environmental Cooperation that Canada is violating its Fisheries Act with regard to industrial aquaculture. Such a finding could lead to international action to force Canada to protect wild salmon, ideally by relocating fish aquaculture into contained tanks on land.

“Applying the Fisheries Act to fish feedlots as it is applied to all other marine users and removing feedlots from salmon migration routes will benefit wild fish and the economy of British Columbia,” said Miller. “Moving to contained aquaculture on land will benefit areas starved for employment and clean up the rivers to restore wild salmon runs.”

Scientific evidence of harm to wild salmon swimming through B.C. waters from fish feedlots has been mounting, as has public concern that feedlots could spread epidemic diseases. This is a threat that jeopardizes the health of every wild salmon run along the Pacific Coast, since U.S. and Canadian stocks mingle in the ocean and estuaries.

The Canadian petitioners are the Pacific Coast Wild Salmon Society in B.C. and Kwikwasu’tinuxw Haxwa’mis First Nation, a native tribe whose territory off northern Vancouver Island is being used by 27 Norwegian-owned salmon feedlots. The U.S. petitioners are the Center for Biological Diversity and Pacific Coast Federation of Fishermen’s Associations, the largest trade association of commercial fishers on the west coast, representing family fishing men and women. The University of Denver Environmental Law Clinic helped prepare and submit the petition.
