I suck at fishing. I can do charter fishing, I can also do hand fishing that was fun in Belize even if those locals were shady... I can also do drive around on the boat drinking beer trying to fish fishing.
If it's not one of those then I suck at fishing.
I did catch a fish hand fishing in belize using a soda bottle as the reel. Was very interesting... at one point in time I thought my wife and I were going to be kidnapped and murdered, but they turned out to be very nice locals!
Now crabbing... there isn't a person here that knows more about catching, cooking, and eating crabs than me.
edit: unless you're an actual waterman... then maybe you know more than me
