I agree. This is likely a larger undertaking than it might appear, but I agree. Many early American explorers have their various monstrous fish stories. I seem to recall the Lewis and Clark expedition describing a monstrous fish or fish skeleton. Plenty to work with. I also would like to point out that Gaslamp's Clockwork Empires seems to be getting good mileage out of "fishpeople" who serve as a general menace to players. I am not suggesting that fishpeople be used here, of course, but I do think some sort of coast-specific threats are in order.
