I would agree completely with that and it's a difficult balance to achieve, especially considering that it really needs to be addressed at an early if not the first stage of pike fishing.
On the one hand you have the imbeciles that see pike as the murderers and stock depleters of many fisheries that deny them bigger catches and on the other hand you have those that understand and appreciate how fragile the species actually is, and a species that will only survive in a balanced natural environment without the intervention of "he who knows better" and whom is happy to catch an endless stream of over populated, stunted and diseased fish.
Quite how you could educate and police this, other than doing what you did albeit too late for that poor fish but with the best intentions, i'm not sure.
