Big blues the teen size not the 1 to 5# variety moved off shore to spawn, some of the bluefish fleet in NJ after not being able to find them yesterday switched to fluke fishing around mid day. The sharkers had them all over the place finning on the service and they didn't bother them. You are on an Island not the coast. Long Island is on a 90 degree angle to the east coast draw a straight line from the middle of the Island out into the ocean and notice how far off the east coast you are. They could just be moving off the island or passing it on there way to the deep as the biggest spawn is the last week in June through the first 2 weeks in July

Bluefish have still been hard to find. Capt Dale read fish last night along the edge of the Mud Hole but other than one nice size blue they were not interested.
There were plenty of bait fish and squid in the area.
During the day we have been looking for the blues and switching to bottom fishing.
Today we had a number of limits of winter flounder, ling and some sea bass.
Everyone went home with fish.
We will be doing the same tomorrow and this week.
If we can't find the blues we will go bottom fishing.
