Re: Plum Island - Where to fish questions
Getting keepers is part luck, part skill, and a whole lot of getting the timing right. Thus, be prepared to put your time in, and enjoy the small ones - at least you are outside and fishing.
If bagging keepers is all you are interested in, you may need to change your location to one that holds more bigger fish and go there when the trophys are there. Best chances for a lot of big fish consistently at PI are in the river during the herring run, long over now, and even that is highly dependent on locations which change from tide-to-tide and as the season progresses.
Otherwise, get a boat.
