What happened to fishing when Ireland joined the EU
Ireland fishing industry was small until they joined the EU. When they joined they gave control of its fisheries to Brussels and had to share their fishing seas with other countries. The catching of fish in numbers increases massively and the majority of fish caught are by foreign trawlers
Describe the nets on the fishing trawlers.
They are big and invisible to fish. Unbreakable
Name methods used to locate fish on a trawler
The sonar or radar use to locate shoals
Three fishing methods, trawlers
Purse seining
Trawling
Drift netting
Reasons for overfishing:
Too many well equipped trawlers are chasing too few fish, technology
When Ireland joined EU they gave up control of their waters and it was open to foreign trawlers
Juvenile fish are being caught because the nets have small mesh
