1  Fishing

2  Canada’s oldest industry  We have the longest coastline in the world  We have more lakes than the rest of the world combined (60% of all lakes are in Canada)  80% of catch is exported to 80 countries ($4.7 billion 2002) 48 lbs. Ling Cod Winter Harbour. B.C.

3 CategoryDescriptionExamples Groundfish Feed and are caught near the ocean floor Cod, halibut, haddock Pelagic fish Feed and are caught near the surface Salmon, tuna, herring Shell fish Animals without backbones & had protective shells Lobster, shrimp, oysters, scallops CodTrout Lobster

4  Fishery: a place where fish are caught for commercial purposes OR the industry of catching or rearing fish  Inshore Fishery: commercial fishing done close to shore in small, independently owned boats  Offshore Fishery: commercial fishing done farther from shore in larger company-owned boats

5 One of the most common methods of fishing in the world. It involves towing one or more trawl nets behind a boat or in between two boats. Nets differ by their mesh size.

6  Set horizontally on the ocean floor (demersal longlines)  Or set near the surface of the water (pelagic longlines).  Tens of kilometres long and carry thousands of hooks.  Baited hooks are attached to the longline by short lines called snoods that hang off the mainline.

7  Towed dredges are used to collect shellfish such as scallops from the sea floor.  The dredge is towed along the bottom until it is full, then lifted onto the boat and the contents tipped out.

10  Historically Grand Banks have been one of the world's richest fishing grounds.  Most parts of the Grand Banks are less than 50 m deep  Light can reach the sea bed and favours reproduction of sea life.  Beyond the banks, the ocean floor descends to depths over 2,000 m

11 Decline in East Coast fishery since 1990 Newfoundland: Decline due to:  Overfishing by Canadians  Improved technology  Foreign factory ships  Changes in natural conditions

12  1497 - English explorer John Cabot reported lots of cod  1600s - 1700s - Newfoundland prospers from cod fishery  1954 - The first factory-freezer trawler in the world could catch and process as much as 600 tons of fish in a single day. They were able to fish around the clock, year-round and in all but the worst of weather.  1974 - Cod stocks and the economies that were supported by them were in desperate shape. Governments worldwide responded with huge subsidies to assist fishermen.  1976 - In response to declining fish stocks, most countries passed a 200- mile fishing limit.  1992 - Cod populations continued to plummet to levels 1/100th of original population size. A moratorium on fishing was declared, putting 35,000 fishermen out of work.  1994 - All Atlantic cod fisheries were closed.  2003 - Atlantic cod populations were assigned endangered status  2004 - Canada allows a limited cod fishery but with very restrictive catch limits

14  Sport Fishing  Aquaculture  Seafood Production  Commercial Sturgeon, B.C.

15 Pros  Contain less toxins than farmed fish  Taste Cons  Harvesting can cause destruction of ecosystems and sea floor  Result in unintended bycatch  Less control over ocean pollution

16 Aquaculture:  Fish or shell fish raised under supervision, either on land in tanks or in cornered-off sections of the ocean

17 Pros:  high fish yields without the risk of overharvesting and depleting the wild species  reduce pressure on wild stock http://www.davidsuzuki.org/issues/oceans/ science/sustainable-fisheries-and- aquaculture/what-is-aquaculture/ Atlantic salmon farm

18 Cons: high concentration can lead to growth of disease and parasites if farmed fish escape, they could mate with wild fish and endanger native species http://vimeo.com/11129261 http://vimeo.com/11129261 salmonsacred.org/itinerary April, 2010

19 SeaChoice: Greenpeace working with Canada Safeway and the Overwaitea Food Group Avoid - wild cavier, king crab, haddock, wild scallops, farmed salmon, farmed shrimp, red snapper, tuna Best Choice - bass, clams, Dungeness crab, Pacific herring and halibut, wild Pacific salmon, northern shrimp, farmed trout, farmed mussels and oysters http://www.davidsuzuki.org/what-you-can-do/food-and-our-planet/suzukis- top-10-sustainable-seafood-picks/
