shimp as bait

[Ggiannig89]

So last time i was out fishing la jolla there seemed to be a ton of bait between macs, krill, and shrimp ( in fishes mouth / belly). It was a pretty slow day of catching with small bites and mostly small fish but in one of the fish I caught I managed to pull out a pretty much whole shrimp out of its mouth and used the shrimp as bait to catch 2 of the bigger fish of the day. So my question would be do any of you guys ever use fresh dead shrimp as bait? If so where do you get it? Or better yet does anybody ever use live shrimp as bait? If so where do u get that?
