Transcript of Fish Farms

Fish Farms By Lydia Tang
May 2, 2011
Socials 10, Block 2-3
Ms. McGill and Ms. Moon Elaina Flounder •Fish farming is a controversial and highly debated topic
•A lack of jobs in British Columbia forced me into this profession, but I am actually against fish farming
•Industry hides it's problems from public scrutiny; swarms of sea lice, disrupting nature's ecosystem, harmful chemicals used to maintain farm
•While fish farming has benefits, the irreparable harm it inflicts is too great, and fish farming must be stopped before control is lost The Main Course •Salmon is the most farmed in BC
•Coveted for nutrients: protein, selenium, calcium, vitamin D, and omega-3 fatty acids
•Have harvested them too quickly for their population to grow again
•In nature, the salmon is given time to spawn and grow their numbers to feed the ecosystem Running the Show •Salmon is vital in the ecosystem
•Feeds animals in the river and ocean
•Part of First Nation's diet and culture for millenniums
•After death, eagles and bears feed on their bodies in preparation for winter
•With salmon population decreasing, animals will starve and die
•A chain reaction that could be felt from years away Who am I to Say? •Fish farming for over five years
•Has seen everything behind what aquaculture has broadcasted themselves to be
•A member of Greenpeace, WWF, Treehugger, and many local groups against fish farming Blood Sucking Parasites •Sea lice is one of the most stomach churning flaws of fish farming
•A few sea lice can easily multiply to thousands because of the enclosed pen
•Wild salmon are not shielded from these pests; sea lice can float through the netting
•Small fry are more vulnerable to the lice; bodies are too small to sustain itself and the parasites
•In nature, fresh water does not contain the parasites
•Salmon only reach salt water when they are strong enough to endure a few lice
•With sea lice, fewer salmon are returning to spawn The Other Side of the Same Coin Three is Company •damaging the ecosystem
•sea lice
•toxic chemicals •One may argue: fish farms would provide jobs (economy) and a safe upbringing for salmon, with plenty of food. There is convenience, availability, and low costs.

•With harmful chemicals and sea lice, salmon are better off in the wild
•If the salmon ever escape, diseases could be spread
•The food fed to farmed salmon contain toxins, injected with antibiotics to help
•Fish farming takes away jobs from commercial fishermen
•Farms also cause inflation in the fish market (cheap, mass production)
•If the ecosystem is destroyed, there would not be any people left to work for
•Who would trade health and a strong ecosystem for convenience, availability, and low costs? Destroying Without Impunity •Sea lice consume salmon before land animals can, the animals will die
•The ecosystem and economy will collapse
•The chemical in fish farms spreads through the water, kills all of the sea creatures on the ocean floor
•If farm is damaged, chemicals will leak and pollute everything around it
•Humans need Earth to survive
•Even if everyone dies, nature would move past this and continue on Not Good Enough •An unrealistic solution for fish farms is to ban them
•Compromise?
•Improve and raise fish farm standards
•Sea lice: add small fish which feed on parasites, minimizes the pest and the amount of chemicals needed
•Pollution: Close tanks off from open waters, circulate water to keep clean and prevent chemicals and diseased salmon from polluting the ocean
•Reduction of sea lice will save the wild salmon and keep the ecosystem strong
•Disease: Vaccination, reduces the need for antibiotics References http://lightbulbs.org/eco--tech-aquapod-helps-oft-move-fish-farms-to-open-oceans-for-sustainable-aquaculture
