Today you are going to
look at aquaculture.
1)
Define Aquaculture (1 mark)
Aquaculture
is defined as the
rearing of aquatic animals or the cultivation of aquatic plants for food.
2) Look at the Social (on people), environmental, and economic pros and cons of aquaculture. For each of the three you should list 3 pros and 3 cons. (18 marks)
Social pros:
-can
help feed people
-can
increase scientific knowledge and technology
-can encourage local investment
Economic pros:
-can
create jobs in the community
-increase
revenue on city
-can
reduce seafood trade deficit
Environmental pros:
-can
place more emphasis on protecting coastal waters from pollution
-may
reduce fishing pressure on certain wild
stock
-Fish Farms can be created on Coastal
Areas and Inland Lakes and Rivers
Social cons:
-can conflict with
other users of water bodies such as lobster men, fishermen or migrating fish
-can threaten
livelihood of fishermen
-there is a risk of
eating the supplied fish from fish farms
Economics
cons:
-can be an
unpredictable enterprise for small local communities
-although farmed salmon
production has risen dramatically the number of jobs in it has not. Wild
fisheries employ five times as many people than farmed fishing.
-wild fish are
worth more to Bc economy than aquaculture
Environment
cons:
-Can compromise the beauty of coastline
-Can transfer disease and parasites to wild fish populations
-Can pollute water
systems with excess chemicals and
antibiotics
3)
Write a short paragraph (7-10 sentences) explaining your point of view on
aquaculture. Is it a good thing? A bad thing? Why. Use examples from your pros
and cons in #2. (6 marks)
I think aquaculture
is not a good thing. As I was researching I saw more cons than pros with this solution.
For instance excessive use of chemicals, such as antibiotics, anti-foulants and
pesticides, can have consequences for
marine organisms and human health. If a fish which was farmed escapes it can
interbreed with local wild stocks of the same population. Which leads to
altering the overall pool of genetic diversity. Excess food and fish waste
increase the levels of nutrients in the water and have the potential to lead to
oxygen deprived waters that stress aquatic life. Why find a solution that damages more of the marine organisms when its suppose to help improve its life?
