3. Over- exploitation of a resource
 Fish is a renewable resource.
 The over- exploitation of this resource can lead to its
depletion.
 Most fish are caught along the continental shelf.
 This means they are caught around the coast of all
continents.

4. Ireland’s Fishing History:
 Has many fishing ports.
 Location beside the Atlantic Ocean.
 Aided by the continental shelf and shallow waters.
 Ideal for fish to live and grow.
 Abundance of plankton
 Heavily involved in the fishing industry.
 Income and employment

5. Overfishing
 There has been a lot of over fishing in Ireland.
 It’s become a major issue causing many people to lose
their jobs in the industry.
 Overfishing occurs for the following reasons:

6. Membership of the EEC (EU)
 When Ireland joined the EU in 1973, we gave up control
of our waters.
 We had to share our fish with other member countries.

7. Modern Technology:
 Sonar technology and radar equipment means fish are
easier to locate and catch.
 Increase in the size of trawlers, they can stay out at sea
longer and catch more.
 They can also process and refrigerate the fish out at sea.

8. Mesh:
 The mesh size in nets used to be small.
 It meant young fish were being caught.

9. Seasons and Quotas:
 As there was no closed fishing season, all fish could be
caught all year round.
 Fish were not able to replenish themselves.
 There was no limits on how much trawlers could catch.

10. Sustainable Exploitation of fish
 Many fish are now endangered because of overfishing.
 Ireland had to limit the amount of fish aloud to be
caught.
 The following steps were taken:

11. Steps:
 The creation of conservation zones around Ireland.
 The introduction of yearly quotas.
 A ban on endangered species.
 Shortening of fishing seasons for some types of fish.
 An increase in mesh sizes.

12. Learning Outcomes
 Ireland’s fishing history.
 There was once lots of fish- good plankton
numbers= good place for fish to breed.
 Overfishing including the reasons for
it.
 Membership in the EU, modern technology, mesh
sizes and seasons and quotas.
 sustainable exploitation of fish.
 Conservation zones, quotas, net sizes, seasons,
endangered species.
