Princes – who sell more 
tinned tuna than any other company in the UK – 
are going to stop using a fishing method which is responsible for killing 
sharks. 
And supermarket chain 
Asda have today also announced that they will shift to greener fishing methods 
for their canned tuna. 
The move follows a 
campaign waged by Greenpeace, who earlier this year placed Princes at the bottom 
of a tinned tuna sustainability league table.
