Methods of Fishing in Canada
In Shore Off Shore
➔ small boats with limited gear, self-employed
➔ 85% of fishers but just 10% of fish
➔ day trips only, no trips during bad weather
➔ low income➔ lobster, shrimp, clam, cod,
and haddock
➔ large ships with variety of gear, company owned
➔ 15% of fishers but 90% of fish➔ out for two weeks or more at a
time, in any weather➔ reasonable income➔ harvest cod, sole, halibut,
redfish, flounder

Environmental Sustainability:
Are These Sustainable?
Economic Sustainability:Collapse of Canada’s Fisheries
Collapse of Cod: 1992
CAUSES:❖ Overfishing (we caught
too much too quickly!)❖ Illegal fishing done by
foreign boats (foreign=from other countries)
❖ The government failed to intervene in time
IMPACTS:❖ 35,000+ people lost their jobs❖ The government finally placed
a moratorium on cod fishing in 1992
RECOVERY:❖ Since 1992, fish stocks have begun recovering, but still a
long way to go!
