Anything really works for skate. Bonito worked well for me when fishing off the bluff wharf. Have also caught them using Dogfish for bait as well, so I’m pretty sure they’ll take most other baits as well. All the ones I have had have been on a standard ledger rig. One thing I noticed while fishing at bluff was that all 6 skate I caught, were all on the same day, and all the other 5 days I caught none.
