The answer for me is that I often fall asleep by 2300.

(of course that's cause I'm up up at 430 to go fish...)
But let me add my two cents.
1) Large Browns and Bass are known night time feeders.
2) I've been out when it's dark, bit of a pain just finding your boat spot.
I think stationary bait fishing is the way to go. I wouldn't want to troll
around except maybe during a full moon (hmm...food for thought there..)
Lantern fishing to draw baitfish to the boat is a known night time tactic.
3) Getting home after midnight and then cleaning fish isn't fun.
In the cold months you could leave it till the morning, but not the summer.
I remember this from my night bluefishing days.
4) I read through the DEP regs and didn't see anything specific regarding
night fishing. I've run into the DEP bird boats at night but never the DEP police
anyway. But, I think there might be some USCG regulations regarding lights on
a boat in any waterways at night, although I don't know
if they apply to small boats. In anycase I wouldn't imagine that's enforced anyway since DEP assumes patrol responsibility rather than the USCG.
