I'm saying I see fish as food. I kill what I want to eat. As quickly as possible.
I try not to catch species i don't like, or fish that are undersized (there's no way to actively avoid catching roe-bearing fish).
If I see a fish has been badly damaged and is unlikely to survive (foul-hooked, or blown swim bladder), and is not something I want to eat,I'll kill it for the otters.
Other fish I don't want to eat go back alive.
I don't consider catching a fish the same as catching a human to eat. That would be messed up logic.
I don't feel any guilt about fishing. None at all. My fishing causes no damage to fish stocks

, and almost no damage to the marine environment.
