They have got to be joking,Sea angling fish numbers are miniscule compared to commercial fishing.
I believe whitingstall instigated a no fishing zone off part of the Isle of Man coast,but it included angling and commercial fishing.
His idea worked,the fish had a safety zone,and bred,and thrived.
what the idea is,is to move the zones after a given period.
The fish that bred in the zone thrived,and spread out from the area,thus being a boon to fish stocks.
Perhaps if they were to ban the factory ships like the ones that anchor at the mouth of the Bristol channel,and hoover up tons of fish,it might be a more useful idea.
