Transcription de la présentation

  1. Offshore Trawler

  2. Offshore Fishery • Deadliest Catch • http://www.youtube.com/watch?v=CRO6H8puHF8&safety_mode=true&persist_safety_mode=1 • http://www.youtube.com/watch?v=w1z-hdqEewI&safety_mode=true&persist_safety_mode=1

  3. Atlantic Fishery and the Marine Food Chain • Phytoplankton flourishes in ocean water where they can get plenty of sunlight and nutrients. • waters off of NL and NS which are less than 200 m deep due to the continential shelf, ideal conditions. • Phytoplankton is the start of the food chain. The order is: Phytoplankton-Zooplankton-Capelin and Herring- Cod, Haddock, and large marine animals.

  4. The Marine Food Chain • A scene from Finding Nemo • http://www.youtube.com/watch?v=ea6yjT65wSQ&safety_mode=true&persist_safety_mode=1 • http://www.youtube.com/watch?v=cWRIR39N8WA

  5. Lobster Fishing • Lobster is Canada’s most valuable fish export. • Worth 1 billion a year. • 55 countries around the world consume lobster from Canada. • Most of the catch is from within 2 to 5 km of the shores of Nova Scotia, New Brunswick, Prince Edward Island, the Magdalene Islands and the island of Newfoundland.

  6. Lobster Fishing • Rick Mercer Report: Lobster Fishing in NB • http://www.youtube.com/watch?v=8syXAjtnDic&safety_mode=true&persist_safety_mode=1

  7. Processing Atlantic Fish • Technological change in the Atlantic Fishery • Better cold storage transportation: before the fish had to be dried or salted first before it could be transported over long distances. • Large trawlers, bigger nets: catch in hours what used to take days.

  8. Processing Atlantic Fish Cont. • National Sea Products (Lunenburg, Nova Scotia) is one of the largest fish processing plants in the world. It takes up over 3 hectors of land. 1000 people are employed there. • The company owns 5 stern trawlers and 6 scallop draggers. Also fish are purchased from inshore fishers and foreign trawlers in the offshore fishery.

  9. Processing Atlantic Fish Cont. • National Sea Products (NSP) (Lunenberg, Nova Scotia) is a vertically integrated company, which controls all aspects of the fishing process, from catching to processing to marketing. • Vertically integrated company: a company that controls all aspects of production from raw materials to finished goods.

  11. Processing Atlantic Fish Cont. • After being sorted by size and species fish go through the processing lines in 3 ways: • 1. iced, sent to fresh buyers • 2. frozen and distributed to restaurants, supermarkets, etc • 3. precooked convenience foods, fish sticks, burgers and nuggets.

  12. Processing Atlantic Fish Cont. Transport trucks distribute the products across North America. Ships move products overseas. 65% of raw fillets are sold in the domestic market while 35% is exported to the United States.

  13. Collapse of the Cod Fishery • Technology changed: • Trawlers with dragnets instead of small boats inshore. • Can keep fish fresh by cold storage ships or trucks. • Over fishing by Canadian and European fleets. Quotas were too high. Dragnets damaged the plant and animal life. • Russia, Japan, Korea and Poland joined the fishery. • Seals were increasing so they caused a decrease in the cod stock. • Change in water temperature
