I don't catch fish but if I did:
-Get close to gaff
-Simultaneously gaff and either reduce drag or put reel in free spool stick rod in holder
-Pull bloody fish on lap
-Put leg over
-Game clip fish
-Tell you gorgeous creture you love her and are sorry about what your gonna do but she wont be wasted
-If YT pop the gill to bleed the fish if WSB maybe a knife is easier, bleed out fish
-Rinse deck or kayak
-Look out for jaws
-Put fish on deck in a gunny sack and occasionally splash water on it, or I bought one of those insulated kill bags from oex which I really like but Im not sure what fish think of it.
-Gut the thing ASAP like a rainbow trout
-Ice for 24-48 hours do not let fish lay in water just on top of ice and drain water as it melts.
-Clean fish
-Vacuum seal what you dont eat (or just release it before this whole fiasco)
-Enjoy
