Hopefully it will give anglers an idea of whether or not a fishery is managed correctly. However, until something is such as this is made compulsory there will still be overstocked commercials raking money in and not caring about the consequences on their fish. And whilst this is an excellent idea, there are unfortunately those anglers who will fish a lake no matter how badly it is maintained, if it means they are "guaranteed" a double/twenty/thirty etc.
