Free-range
In what year did the government place a moratorium on cod stocks in NL
1992
Fish farming; breeding and growing of fish in controlled spaces
Aquaculture
The outer edge of the continent that extends below the surface of the ocean
Continental shelf
List 3 reasons for the abundance of fish off NL
- cold Labrador current flowed form the north and meets the Gulf Stream causing the water to be nutrient rich
- sunlight reaches the shallow ocean floor of these rich fishing regions and supports the growth of plankton which is the main source of food
- many forms of coral have been discovered along the coral reefs of Nova Scotiaโs continental shelf which is believed to be a keystone species
Fish that prefer to live on the ocean floor along the bottom of the shallow continent shelves like cod
Ground fish
Fish that swim in open water like sardine and salmon
Pelagic fish
like lobster, crab, mussels that are found on the ocean bottom and usually caught in traps or weirs
Shellfish
Explain the significance of the fishery in NL
- direct employment
- percentage contributed to the gross national product: total value of goods and services in a nation over a year
- spinoff employment: food (restaurant), trucking industry, dockside, grading, etc
- income for government:
- royalties used by government to stimulate other economic ventures
- royalties used for infrastructure development (roads, hospitals, etc)
List and describe 4 reasons for the decline in cod fishery
- temp: slight drop in the temp which drives certain fish out of their habitat
- increase in the number of seals put pressure on the marine ecosystem
- foreign factory freezer trawlers permitted to fish for cod
- too many fishermen chasing too few cod (greedy)
A net that can be used in shallow or deep water, the net consists of a mesh that is suspended to hang like a wall on the ocean bottom (referred to as ghost nets)
Gill net
A floating net that encircles a school of fish and is closed by a line that resembles a downstring
Purse seine
A funnel shape net that is attracted to a stirs trawler by towing cables, as the net is towed along the sea floor, two large door like boards hold the net open to scoop the fish (is most destructive)
Otter trawl
A device used to trap fish made of a net supported by a wooden stakes
Weirs
A simple device consisting of an enclosed structure with an opening in the side or the end
Lobster trap, crab pot
What are some pros/cons of the aquaculture fishery?
Pros:
- main economic base of many coastal communities
- farmed fish are rich in omega 3 fats and are equally as healthy to eat as wild fish
- farmed fish provide a large supply of protein while wild fish stocks decline
Cons:
- fish are raised in densely packed net cages so diseases spread quickly
- farmed salmon contains more fat than wild salmon more toxic contaminants like pesticides that may affect human health
- antibiotics and pesticides to prevent disease contaminate water which kills wild salmon and could harm the consumer
