What is overfishing? Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans.

Why overfishing is a problem? We are losing species as well as entire ecosystems. As a result the overall ecological unity of our oceans are under stress and at risk of collapse. We are in risk of losing a valuable food source many depend upon for social, economical or dietary reasons.

What can you do to stop overfishing? Safe catch limits A constantly reassessed, scientifically determined, limit on the total number of fish caught and landed by a fishery. Controls on bycatch The use of techniques or management rules to prevent the unintentional killing and disposal of fish. Monitoring and Enforcement A monitoring system to make sure fishermen do not land more than they are allowed to, do not fish in closed areas and cheat as less as possible. Strong monetary enforcement is needed to make it uneconomic to cheat.

The main characteristics, problems and management strategies of commercial fishing, particularly in Atlantic Canada.

Types of Canada’s fishing industry (pg118) Find definition from text book (pg.119): continental shelf banks inshore fishery offshore fishery

Fishing was Canada’s first industry, but unfortunately it has taught hard lessons about the importance of sustained yield practices Natural factors of ocean currents and shallow water made Atlantic Canada the country’s leading fishing region

Inshore fishing is sustainable but the offshore fishery has not been so, with the result that the Atlantic cod resource has been almost completely destroyed Today, the Marine Stewardship Council (MSC) works to improve the sustainability of Canada’s fisheries

H.W. Pg 121 solve Ques.1,2,3,4,5 What are the main differences between inshore fishery and offshore fishery?
