Go to the fish market past the boat marina road goes to one way will be on your right or you can get it at the walmart looking store on the left when you come into town next to sams club.
I just use kastmasters or shad plastic lures. Then you can chop up your catch for bait.
Sometimes, squid can be impossible to find in Rocky Point. I usually bring it with me. Lee-Lee Market at Dobson and Warner always has it locally, or check any Asian market if you're on the west side. We get a couple boxes of the frozen California candy squids. Lee-Lee also has frozen baby octopus, which is tough and works great. Harder to tear off the hook than squid.
I have good luck with squid on the way to the Malecon. As you pass Latitude 31 a block or so there are vendors on the street to the right. If they have sqid they are very good quality ( food quality ) . Tell them you want them for bait and the price is less. You should be able to get about 1 1/2 lbs for $ 3.00 dlrs . If they are out go to the malecon and one of the vendors may have some but I have the quality to be lacking freshness. Keep them cold as they spoil fast. If you are in an RV and you plan on keeping them in the Frig use quality Zip Lock bags and double them up
