Not a good idea for so many reasons.
Not all anglers show restraint, the expression fishmonger springs to mind.(anglers who fish purely to make money)The use of prawns, shrimps and god knows what else would be used (again)
It is very difficult to pressurise governments to stop high sea fishing if UK anglers are killing and selling fish. Why should the netsmen give up their livelyhoods to give anglers sport.
just don't go there
