Jack Stewarts book say find the whites then chum with leaf /trout worms over your anchor spot in late summer ! I guess the frenzy starts under the boat I think jigging a kastmaster tipped with a worm chunk would them nail these guys in .I think I'm going to try this soon.I gonna cut up the trout worms still in the cup ,find suspended fish on sonar in 25 ft of water anchor up ,chum then jig with the tipped spoon. I think 4 cups is 8 doz trout worms 10 bucks .I will use 1 cup for bait and start chumming with 1 cup cut save the others when the action slows .Chumming with anything except terrestrials is not legal in NYC res !
