So first time I caught I fish, didn’t even know where to start .. how to cut it open.. what parts to take out and so on..
I learned messing it up and practice makes perfect!
I found this website that explains step by step..
Cut all the way to gills.
Pull the guts out.. literally..
Clea it with water and rub with fingers until most blood is gone..
Make a cut between skin and meat and VOILA! you are readyyy
