I agree with Noelm on this if you're not going to use it don't kill it,some of the fish I see some people keeping are not good eating .I am fairly fussy with what I keep even flounder are given to elderly friends as we won't eat it in my house. It reminds me of going hunting as a young bloke my mate shot a roo and just left it there. it seemed cruel and stupid to me and no I'm not a greenie
