Well I would say anything more than 1 or 2 for the table is enough for anyone and if they are undersize then obviously the 'How many is as many as he can' argument goes out of the window completely.
Alan,
Is this person shore fishing or boat fishing?
A few months back, my missus told me about the transit van going around our streets trying to sell fish to unsuspecting locals. One older lady down the road bought some and had to chuck it out. My missus noticed that there was no refrigeration unit on the vehicle so the fish was almost certainly rank and wether or not it's the same lads selling every year I don't know but there have been many complaints around the North East about fish being sold on the doorstep that are not fit for consumption.
What I would like to know is where are these fish sourced from? Is it what the commercial boats don't sell or is it the a group of lads going out every day on their pleasure boat and catching 'as many as they can'
Although most of us have issues with the commercial sector and their practices, it has also been mentioned from some of their members that they are aware of a small minority of anglers who catch their fish to sell without the relevant licences
