What's the best way to euthanize a fish?

[Earl]

I was told just bang its head on the riverbank, but I've heard people say pull them backwards in the water, but that sounds a bit cruel.

Some fish are too big to just slap against the canal side though, is it worth using a knife or a gun?

[jools182]

12 bore ought to do it

[Earl]

Not good if you're poaching though.

[jools182]

[Earl]

Problem solved.

Would there be much fish left though?

[Major Starbold]

Most sizes of handleable fish will croak when hit on the head with a priest.

[Major Starbold]

Priest.

[Ck]

The kindest way to kill a fish is to pop them in a bag of water then put the bag in the freezer.

[Earl]

Most sizes of handleable fish will croak when hit on the head with a priest.

Aye, but what if you catch one of these, like I did.

[Hutchybee]

I say you throw it back!
