Sort of like we know of some illegals but most aren’t documented and tagged.
You got it; and have hit on an aspect that will be more forthcoming this summer of 2021.
"Dr.Greg Skomal Mass. Div. Marine Fisheries ,who has probably tagged more white sharks than anyone else says that, to date, 230 animals have been tagged."
"DR. Skomal estimates that is about 20 percent of the total Massachusetts white-shark population have been tagged, mostly around Cape Cod."
What does that mean? Well, to Capt. Tom, if you are at a Massachusetts beach, and you are in the water and have a white shark "encounter", chances are 4-1 the shark is untagged since it can’t, and didn’t ping any buoy to give you a warning.
But relax there will be more eyes on the water looking for fins this summer.
Yes, but what happens when ....? Those problems will be worked out in the future.-Tom
