NOAA has alot of great research and programs aimed at a variety of things.
It sounds like this person thought you were a good candidate for the charter boat study, But perhaps missed someone who actually uses those charter services. Someone who doesn't really know the sport could assume that all fisherman must use charter services that target a different species than you were fishing for. Though I doubt that is the case, just trying to get another survey filled out it seems.
I know I don't target those fish species usually, and as a boat owner.. I'm not particularly interested in charters, and would rather stay home as well.
So whether it was inept or lazy research assistant trying to get their quota of surveys filled out, or a misplaced research inquiry..
Whatever the metric, certainly tough to tell what the value is...
