There are all kinds of fish that will work for bait for lobster fishing, I have even heard of guys using chicken and even cat food too. For me the two best baits have been salmon heads and mackerel. you can find both at Asian seafood markets and now I’m glad to tell you that you can get them at the bait shop on Belmont Pier too. yes on the pier they have salmon heads for sale for lobster bait. I'd suggest you either cut the heads in half and place them in your bait cages, the mackerel you can cut into little chucks. Make sure you use metal cages or the seals will eat all your bait before the lobster get a chance to. Also the fresher your bait, the better you will do, good luck.
