The Scout Law says that you should not kill God's creatures without
good reason. It is allowable when you need them for food. In the case
of fishing you often catch them when practising, but you need not kill
every fish you catch; you can take them carefully off the hook and put
them back into the water.
The hook as a rule catches them in the lip, which with them is not the
tender flesh that it is with us, but merely a lot of bones held
together by gristle, so they do not suffer pain as we should--and this
is shown by the way the same fish will come on again after having been
already caught.
When you want to keep a fish that you have caught, you should kill him
at once and put him out of his misery, and this you can do either by
hitting him on the head with a stick, or by driving your knife into
his brain, or by putting your finger down his throat and then bending
his head backwards and breaking his neck.
