I'd suggest that
@Old Man familiarise himself with the law, the links above detail all the rules that apply to EA controlled waters in addition to highlighting the need in for permission on privately owned fisheries or waters on privately owned land.
To be honest I have no issue with fish being taken for the table provided they're taken in line with the law.
@robfosters I understand where you're coming from, I used to do a lot of sea fishing and would regularly see large numbers of undersize fish being taken which is just wrong.
I've also heard of plenty of occurrences where people are illegally fishing and taking fish from private waters - it's just difficult and sometimes dangerous to enforce though
Anyway, threads going off-topic - only recipe I know is the classic wrap it in wet newspaper and bbq. I think pike probably a bit to bony and fiddly for my liking

wouldn't say no to professionally prepared though.
