Its my understanding that there are a lot of ducks up there in the fall.
I've seen guys fishing the mouth of all the feeder creeks at the start of the outgoing. You could put your yak in by the boat ramp, make a left as soon as you cross that bridge if you are heading towards the beach. Its a dirt road, if you got to the 1st light you went to far.
Live line a perch?
I fish the tuckahoe alot since I live 2 minutes from the boat ramp. Lots of perch and catfish all year round. Caught some fluke out at the mouth last year, one little striper in the summer. Crabers always tell me they get tog in their traps sometimes. If you venture up the river one a high tide you can find some big pickerel and some bass sometimes. Have caught yellow perch too.
You are required to have a current NJ Fishing License displayed in your vehicle to launch at the boat ramp at Tuckahoe WMA. The small ramp in Corbin City is free (I believe). Parking there is an issue, though.
And yes, there is plenty of activity to be had in the entire length of that river...
