Tons of Sharks in the Shrewsbury River???

[Arbutis]

It was a VERY interesting morning! Left at 5:30 home by 8:30.* Me and one other guy.* We caught tons of fluke (mostly shorts), one beautiful weakfish!, scooped a bunch of big crabs that were just swimming on the surface and we had a very interesting encounter. . .
We swore that we were seeing small SHARKS all morning long.* Dorsal fins were popping up everywhere and occasionally we would see an attack and a huge splash! I thought I was going crazy. So we made an attempt to catch one by tossing a plug right in front of the fins. . .
No takes. Several close shots but no bites.* Later, on our way back in some guys crabbing asked us if we have been seeing sharks!* Then in the distance we saw the motherload.* In like 3 feet of water there were schools of them in the hundreds all over. Breaking water and finning.* I threw a big treble hook on my line and we headed over to have a look. . .
I tossed it in and immediately hooked up and line started peeling off the reel!* Others were breaking water and swirling and splashing all around us in the shallows. After** a 10 minute battle with a tiny rod and 10 pound test line, we landed our fish.* It wasn't a shark! But I think I solved the mystery of why there have been no blue crabs in the river this season. . . What's YOUR guess?
