1 East Coast Fisheries Fish in Canada was once thought to be a renewable resource; however the fisheries collapsed in the 1990’s = renewable resources must be managed properly Canada is not 1 of top 10 fishing nations but it is one of leading fish exporters (80% exported)

2 East Coast/ Atlantic Fisheries
Inshore Fishery: commercial fishing that takes place within a few kilometers of the shoreline. Small fishing boats go out to sea and return to shore each day Offshore Fishery: ocean fishery using boats longer than 25m. The boats stay at sea several days before returning to shore with their catch

3 Crisis in the East Coast Fishery
1980s – East Coast fishery catching fewer and smaller fish; fishery collapsed unexpectedly in 1991 Canadian government stopped all northern cod fishing and limited other catches of ground fish Expected fish populations to recover, but still haven’t (diagram page 283)

4 Why it Collapsed Overfishing – more fish were caught than reached maturity Improved Fishing Technology – easier to catch fish/overfishing easy Uncontrolled Foreign Fishing – not controlled until 1970’s Destructive Fishing Practices – when trawler tried to catch one kind of fish, also caught many others; unwanted fish thrown away Changes in Natural Conditions – water temperature dropped and ocean salinity (saltiness has changed Decline of sealing industry = more seals = eat more fish
