Use three down flowing trace about 7 feet overall length.
60 to 80lb mono with 4/0 or 5/0 hooks.
Put some tubing on the trace also and bait with side fillets of mackerel, frozen or fresh.
Don't strike the fish too quickly let the bite develop.
Leave still on the bottom , don't jig!
If you want to use a pirk bait it up and let it rest on the bottom.Personally I don't like pirks have lost too many fish off them.I have caught hundreds of congers using the gear mentioned above. (not boasting just giving you the benefit of my experience

)
Good luck.
