Well then help us understand. What constitutes a "trip". How may "trips" can a commercial fisherman make in a 24 hr period? How long is the pound net season? I know its still in full swing even though recreational fishermen were shut down 9-10 days ago.
And if laws exist stating that commercial fishing boats can be carrying limits from other states on boats within NC waters, that suggests that these are large commercial operations, like global orgs rather than local guys.
As for the the commercial boat operators buying gas from local marinas, im sure thats the case, but one boat full of gas doesnt equal 35% of the recreational fishermen in the country noy buying gas (bait, hotel rooms, meals, tackle, ice, marina fees, etc) that have completely given up on fishing because they cant justify dropping $500 on a weekend fishing trip for 2 fish.
I would agree that not all states are the same. As rotten as NC laws are, some states are even worse. I spent some time doing the math on MD creel limits a few years ago. Between the various species and seasons, one commercial boat might pay $1000 in license fees (the equivalent of 35 rec fishermen), but could take 100s of 1000s of fish in a given year.
Research online pound net maps. If the location and number of these doesn't piss you off then nothing will. Pound nets are like mazes that are setup in key transit areas. Theyre place on the bottom like a series of walls, and once a flounder enters it cant get back out, it winds up in a big box at the end of the maze to be scooped up 100s of fish at a time.
