Fishing Flashcards
What Canadian agency is in charge of maintaining and safeguarding all of Canada’s oceans and inland water resources?
The Department of Fisheries and Oceans Canada
Canada has the largest offshore economic zone which covers ___ million _ km2. Canada controls the waters from the shoreline to ____ nautical miles (370 km) into the ocean.
3.7 million km^2 and 200 nautical miles.
Canada is home to the world’s greatest tidal range (the rise and fall of the tide) which can measure 16 metres. Where is it located?
The Bay of Fundy
Where does Canada rank in the world in terms of seafood product exports?
Canada ranks 7th place
How many people make their living directly from fishing and fishing related activities?
Approximately 80,000 Canadians make their living from fishing.
Who are Canada’s top two export markets of fish and seafood products?
America and China
What were the top two species caught in 2015?
Walleye and Trout
Which province has the largest recreational fishery?
Ontario’s fisheries
Describe the difference between ground fish and pelagic fish and anadromous fish.
Groundfish are fish that live and feed at the bottom of the sea. Pelagic fish are fish that live and feed on the surface of the sea. Anadromous fish are fish that are born in fresh water but spend most of their life in salt water.
Which method of catching fish is the worst for the environment? Explain.
Otter trawling is the worst method of fishing. This involves throwing a large bag shaped net into the ocean, which is then dragged across the ocean floor to catch fish that live in those areas. This method is bad because it destroys the natural sea floor. As the net is dragged across the floor, it destroys everything in its path.
Which three provinces /territories made the most money (landed value) for seafood products?
Nova Scotia, Newfoundland, and British Colubmia.
Describe the major differences between the inshore and offshore fishery.
Inshore fishing has very small boats and only fish within 16-25 km of the shore. Whereas, offshore fishing has very large boats and fish from 370 km from the shore. Inshore fishing also have very limited access to gear and materials, unlike offshore. Inshore also only has a crew size of 1 - 6 people and only take day trips, ommiting bad weather to fish. Whereas, offshore fishing has a crew size of 12 - 16 people and targets to go fishing for 2 weeks or more at a time.
What is Aquaculture?
Aquaculture is the farming of fish, shellfish, and aquatic plants, in both freshwater and saltwater.
What is the continental shelf and how does it help fishing?
In other words, it’s where a portion of a landmass is submerged beneath the ocean, and forms an increase in slope down the ocean. This is crucial for fishing because due to the shallow waters, it receives more sunlight which supports the growth of plankton and other ocean plants. This forms the base of the oceanic food cycle. Where plankton is eaten by zooplankton, which is eaten by small fish like herring, which are then eaten by larger fish and marine animals like seals and whales. Because of this chain, it attracts other fish which contributes to how much fish are caught by anglers.
