Fishing Flashcards
Define and give examples of Pelagic (estuarial) Fish
Fish that feed and are caught near the surface.
Ex: Salmon, Herring, Mackerel, Tuna
Define and give examples of Ground Fish
Fish that feed and are caught near the ocean floor
Ex: Cod, Haddock, Halibut, Polluck
Define and give examples of Shellfish
Mollusks and Crustaceans (animals without a backbone)
Ex: Shrimp, Lobster, Oysters, Scallops
Define and give examples of Inshore Fishing
Commercial fishing that takes place within a few km’s of the shoreline. Small fishing boats go out to sea and return to shore each day.
Define and give examples of Offshore fishing
Ocean fishery done from boats longer than 25m. The boats stay at sea for several days before returning to shore with their catch.
List 5 differences between Inshore and Offshore fishing
Inshore:
- Within a few km’s of shoreline
- Boats go out to sea and return each day
- Individuals and families do this
- Usually 1-6 people go
- Mainly warmer months
Offshore:
- Goes to the edge of the continental shelf
- Boats stay at sea for several days before returning to shore
- Large companies do this
- Usually 12 -16 people go
- All year long in all types of weather
Identify 5 major reasons why it is believed the cod industry collapsed on the east coast. Briefly explain each.
- Over fishing
- The government allowed people to catch more fish than those reaching maturity and sustained yield management was not working. - Improved Fishing Technology
- People developed large, powerful, engine-driven trawlers
- Fishers could locate fish more efficiently, which caused the possibility of over fishing. - Uncontrolled Foreign Fishing
- Foreign countries caught too much fish
- Canada protected their fish stocks, so foreign fishers had to follow Canadian guidelines - Destructive Fishing Practices
- Undesired fish were thrown back into the ocean
- Only remaining fish were reported as caught - Changes in Natural Conditions
- Water temperature dropped
- Salinity levels changed, causing fish to avoid these areas
- Seal population grew, so less cod were found
Where are the 3 areas that commercial fishing occurs in Canada?
- East Coast
- West Coast
- Freshwater In-land Lakes
